Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater By Nuaire

Do you supply the optional controls for the new DRI-ECO-HEAT-HC, and can you tell me the price please? Also, do they require wiring or are the wireless? Many thanks.

Hi could you please tell me if this unit would be suitable to rid us of condensation and mould in a old stone cottage as what the approximate running costs are.

Can you confirm the duct size for drilling the ceiling please? Also, can you extend the duct to two locations with a T-piece as I want to discharge in two locations due to the layout of my property? Thanks Damon

What controls the heater on this eco heat piv. Does it heat the air all winter 24hrs a day? I can't see it being very economical to run would a ordinary PIV be OK for a 3 bedroom bungalow? How do they cope when for instance the outside humidity today is 92% and the inside is 71%? Hope to here from you soon Colin.

HI, can you tell me what the differences are between the Drimaster Heat and the newer Drimaster Eco Heat version please?

We have a loft which has had spray foam insulation added many years ago, yet we have really bad condensation, does the Nuaire product still work effectively with the spray foam ?

I have moved into a period property on three levels including a basement which has been tanked however we have high levels of humidity in the North facing basement and some salts & black mold appearing on a few internal basement walls. Although we are about to upgrade the central heating I expect that high humidity may continue to be an issue would the Nudari Eco Heat or any other system help?

Our attic is sealed with foam spray on the rafters, with an old velux window, would this unit be suitable? How much does this cost to run in a 3 bed semi?

In the pdf on page 3, section 10.4 it says, "The set point ranges between 10 degrees C (fully anti-clockwise) and 20 degrees C (fully clockwise). If that is the case the mid point would be 15 degrees C. But in the I-sells youtube video I posted below it says "they recommend a mid point of 10 degrees." Which is correct please? https://www.youtube.com/watch?v=mz4jbXrkTWM&index=2&list=PLia-C2J6cpQj7CojIV2oWLiQacOnGdkki

Thanks for your reply. I was not asking what temperature is correct for a home as that is subjective. I was asking what the mid point setting of the blue dial is. I assume it is 15 degree C but at 5 minutes 10 seconds of the isells video I posted in my previous post it states the mid position is 10 degrees C.

do I need to close the air-vents that are in my pvcu windows

I have got my central heating boiler in the loft,is it ok tofit a unit also

Hi, I notice in the picture it has a dial on the bottom part, which I guess is for altering settings. Does this means that you have to go up ladders to alter it if need to or I is there a wall mounted switch that can come with it to make this easier which also has an on off switch when away on holiday etc.

Hi. Trying to make my mind up on the best one to get for my house. Reading question 5 from Colin got me thinking which one I actually really need. Normal PIV model or the newer heater version. My upstairs hall where it would go has a very high ceiling. Older style house with 9' ceiling however top to stairs to foor on the first part landing is a good 10 to 11'. I have read that the normal versions pump out cooler air and some have stated it can get a little chilly. Whereas the heater heats the air flow. What is the difference in temperature between the two? and which one is best for an older house with higher ceilings. There's a big difference in price, so would like to get the correct one. Don't want to be left regretting getting one that feels chilly when you walk past it, but don't want one that cost more on my electricity bills when I don't really need it. Regards

Hi.Our loft air quality is not great tends to get black particles floating around which tends to cover boxes etc. There is a v slight smell too. Our insulation in the loft may need replacing it has vermiculite with normal insulation roll ontop. It would be difficult job to replace. My concern is the quality of loft air venting around the house. I have heard people on forums telling stories of musty smells being distributed around the house. Can the PIV filter cope with this or will it need need replacing often surely it would be black in no time. We do have new roof vents so fresh air can circulate. Can you connect the PIV to draw outside air instead of using internal loft air?? A friend of mine claims he has done this but using a Kair PIV unit. I know you could use a flatmaster & connect but we have a standard 3 bedroom semi + loft so would not be adequate. Looked at Whole House Ventilation which does draw air from outside but this is obviously an expensive option. Any

Trying to decide between model with or without heater - what is the difference in running costs?

Why does my nuair fan only switch on when the hall light is on?

If I wish to leave the Drimaster eco heat on all year round to improve air quality, when the weather warms up is it ok to open some windows in my bungalow or will this disrupt the efficiency of the PIV unit?

I have a ground floor flat which has severe mould problems, despite all trickle vents being open. It has only electric heating. Could I use 1 of these units to solve the problem, and if so which would be best? With a heating option if possible.

Hi, we have a 3 bed bungalow with a vented loft space. Bad condensation particularly in bedrooms on windows. In our bedroom we just had a lovely bespoke fitted wardrobe on an outside wall, which infuriatingly gets condensation on external wall if temperatures drop. I'm interested in your product. Would I need 3 units, one for each bedroom? We have 2 close down one end, but another at opposite end of bungalow. Is fitting in bedroom ok with air blowing in vent?

I have a 3 bedroom property that has been over sealed by the previous owners renovations. My sons room suffers greatly from black mould on the walls as does the hall way, which even forms puddles at the foot of the stairs during colder months. I have looked at getting one of these units to help reduce the condensation problem however I think we would need a second outlet in the lads room. You have mentioned in a previous answer about splitting the airflow to 2 locations by reducing the 200mm outlet to a 150mm. How would this work if the heater unit is fixed with a 200mm input? Also do you supply the reducer parts and ducts/diffusers?

our electrician set this at number 1 should it be set at 2 please answer to my e-mail address

Will PIV "work" alongside continuous/constant bathroom fan extraction (6-15 l/s). The concern being that the new air introduced into property by the PIV will simply get extracted by the bathroom ventilation without allowing the PIV to build up adequate pressure/flow. That or the effect of the PIV will be minimised. Would you recommend turning off continuous bathroom ventilation if present?

Hi, I am looking at putting a unit into my daughter's flat and am looking at the heat and non-heat units. there seems to be a bit of contradiction in your previous responses to running costs. In one response you say £30-£35 per year and in another it's £50 per month. I presume the latter is assuming the unit is running constantly, which I believe it doesn't: I understand that you can set a thermostat on it and it is only when the loft air temperature falls below that setting that the heater will 'kick in'. Obviously £50 per month is very highand would be prohibitive so do you have any real data on which to base running costs? Thanks

Hi there does the product come with a 240 v mains plug as I have a mains socket in my loft to plug into.

Hi. Does the ceiling duct have to be positioned in the centre of the house? Due to a loft extension, it will not be possible to put the duct at the top of my stairwell. The only open loft space we have is 8-10ft away from the top of the stairs, above a small corridor. Would the device still work sufficiently in this position? Many thanks.

Which model do I need to purchase for a two bedroom Bungalow,? Also does this unit need to be wired into the electrics,? Do you have any recommended fitters based in the North east of England.?

HI - does this machine make a noise at all? and can it be fitted in a thatched property (it its almost windy in our loft space!)

Hello, I am torn between whether I buy a heated unit or a standard one. What would determine this issue. I need one for a 4 bedroom house, one for a three bedroom house and one for a single bed flat with loftspace. Could you advise? Thanks

Is the heater just for comfort (respondents talk of cool air being circulated when no heater) or is it essential for the quality of the air circulation (is heated air more efficient than cool air)? Thanks Richard

i still have a little condensation on windows after frost i have it on at number 3 i live in a three bedroom bungalow

I would like to know the following: The Nuaire Drimaster-Heat-Eco can have the diffuser on a right wall. When the diffuser is on the roof of the house, be on a side wall, as close to the ceiling as possible. I have loft, but the top of the rooms is low, so I only have the diffuser aside. One more question my apartment has a strange setup, so I'll have to put two of these appliances on each side of the house (and the two with the same problem as the diffusers). But the question is whether they can work together, and with the same commands? Thank you.

Can the heater and unit be supplied from a spur off of the lighting circuit?

is it possible to turn on/off the heating element from the hallway control unit i.e. not just turn it down but disable the heater so that it does not temper the incoming cold air until I want to switch it back on in the vey cold months? (sorry I cant find a user manual online)

Hi, we live in a cottage with condensation / mould problems at the back of the building. There is a hatch at the top of the stairs, but because it's a vaulted ceiling, the only place to house the inlet / outlet would be in the hatch cover. Is this feasible? There is a good sized roof space to one side of the hatch, but this is over a bedroom.

Hi Are the remote controls battery powered? Can I connect both the Humidity and Control sensors together to the unit? Regards

I am hoping to purchase one of these, but my loft hatch takes up quite a bit of my landing ceiling. What’s is the closest the grill can be to walls/loft hatch/light fittings to work efficiently

Hi I have just had the unit fitted by a NUAIRE recommended fitter and after half a days running, the unit has an 'F' flashing on it. According to the manual this indicates a fan failure and requires a replacement unit. Serial Number of unit is 3794989 Please advise Regards Chris

Hi I am having a problem with the drimaster eco. when I try to pair a 4 way switch to the drymaster its not pairing up . I have tried 2 new switches. also when I first power up the drymaster its not doing what its supposed to do hope you can help thanks carl

will this unit do a 4 bed house ? or would something larger be required.

I have the original non heated green Nuair Drimaster which needs to be replaced. Would the new eco heated blue version fit my current square ceiling diffuser (given the heat unit attaches to the new circular diffuser)? Or should I buy the previous green heated model which you have old stock? The eco one seems to be preferable if it will fit. Thanks, Paul Watts

Hi, does this unit come with everything i need to fit it or are there extras required, like switches, controls, thermostats and the vent that fixes to ceiling. I dont want to order it and then find there are additions required. Thanks.

I am considering fitting a drimaster eco heat in the hall of my three bed bungalow the central heating thermostat is 1.5 metes from where I would need to locate the diffuser would this cause any problems. Also the door to the lounge is 1.5 metres away ,would you feel the cold air coming into room. making it uncomfortable

Can you recommend an experienced installer and, if so, what would be the approximate costs for this product?

Do you have a fitting service,I don't like playing with electrics thanks tony

2 things; I have had the unit fitted and it has already cleared up the comdensation problem in 2 weeks flat. I am now looking to set the correct speed[it was set at 4] for normal running going forward and also the temp which was originally set at 14C. Also,what happens to the unit in spring/summer and can it be switched off then? It has been hard wired in to the supply

Do you have to keep internal doors open for the drimaster to work?

Do you know the contact details of a good, reliable electrician in the Meopham, Kent area who has history of fitting these devices? We have asked around and a lot of who we have called have not heard of them?

Hi we live in a tall 4 bedroom house - there are 4 floors including a basement and the ceiling are quite high. Would this unit work for us or is there a different unit that would be better? Thanks

Hi, I have read on forums that people are re-assured that only clean air enters the house, even filtering out traffic fumes - but I read on this site that the filters are only G3. G3 seems to only filter big stuff so no fumes for sure... but will it stop glass fibre dust from the loft, please?

Hi I have a tenanted 2 storey 2 bedroom terraced house and would like to buy one of your units. Looking at your info it does not seem too necessary to buy the heated unit. In my case it would be fitted at the top of the stairwell ceiling. If I bought the non heated one, could I buy and fit the heater part to it later if there were problems? thanks Jon

If I understand the I&M PDF correctly, the only way you can switch off the Heater function is by installing a 4 way switch (and not on the defuser controls)? Also my 3 bed bungalow's inner hallway is only 870mm wide, so I'm assuming I can really only install the model at Speed 2 given the siting requirement in Paragraph 4.1?

Hi i would like to know if their is a problem with the drymaster how do i get it fixed

We have a extract fan in bathroom with open vent in ceiling will this effect the drimaster from working properly or do we need a sealed vent.

Hi can this unit be fitted DIY or for the warranty does it need to be fitted by a trained engineer

Having installed and powered up the Nuaire, how do you then adjust the fan speed? The instructions in the box suggest doing this at install. Do I need to power-off & on?

Hello Could you tell me if this product would be powerful enough to perform satisfactorily in a 5 bedroom house without being too noisy? Thanks

I have a drimaster eco heat fitted.The heater is turned to minimum but running costs have been very high.Is it worth getting a nuaire 4 way switch to turn off heater or how do I disconnect the heater only.

will it work in a dorma bungalow

Which fixing method gives the least amount of noise while in use? The standard fixing or the joist mounted fixing? Do you have something to compare the running sounds at minimum and maximum settings? Such as sounds like distant traffic? of a jet taking off (which I doubt :-) )

My house/area has a high water table with ~1cm of standing water under the floorboards in certain parts of the house at various times of year. depending upon the rainfall and water table. I have high humidity year round due to his, but no condensation issues. Is this unit suitable for my situation? Thank you

How you know if the heater element is working? The air coming out feels as cold as outside. We've turned the up temperate up to max. I look forward to hearing from you.

Do you have a installation service

Hi there. I am considering purchasing the Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater. I live in a single storey stone cottage which suffers from quite bad condensation. The Humidity levels are constantly around 70-80%. From the reviews of this product and your answers to any questions it would seem that this product may help. My cottage is quite long (around 25metres long) with a corridor running down half of it (the bedrooms are off the corridor) then into a large living and kitchen area (10m in length) which has a higher ceiling than the rest of the house. Please let me know if this is the unit that you would be recommending in this instance.

I have a double thickness ceiling to go through as it is old lath & plaster which was tacked over with plasterboard then plastered over. Will this cause a problem for me?

We have put 'Envirovent' systems into a few properties and they recommend that the bottom of all doors are cut so that there is a 10mm gap at the bottom so that air can flow if doors are closed. Is this the same for the NUAIRE systems which I have only just discovered on the I-sells site

In the instructions it says the following under Setting the Temperature Speed Control Option: 1 (Default) At loft temperatures below 19°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 18°C but less than 24°C, the unit will switch automatically to “Intelligent Heat Recovery Mode”. At loft temperatures above 23°C the unit will switch itself automatically to “Standby Mode”. 2 At loft temperatures below 19°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 18°C but less than 31°C, the unit will switch automatically to “Intelligent Heat Recovery Mode”. At loft temperatures above 30°C the unit will switch itself automatically to “Standby Mode”. 3 This option removes the temperature sensing function out of the unit. The unit will operate continuously in “Normal Operation Mode” depending on the volume control setting selected. 4 At loft temperatures below 16°C the unit will operate on “Normal Operation Mode”. At loft temperatures above 15°C but less than 28°C, the unit will switch automatically to “Heat Recovery Mode”. At loft temperatures above 27°C the unit will switch itself automatically to “Standby Mode”. 5 Not applicable for the HEAT model. What are the following modes, and how does the unit operate in those modes? “Normal Operation Mode” “Intelligent Heat Recovery Mode” “Heat Recovery Mode” (I assume this just has the word Intelligent missing? or is it a different mode?) “Standby Mode” Many Thanks, Dennis

hello just had this installed and is working fine, when does the heating side of it kick in, and how hot is the air from it, just need to make sure its working ok, have got the setting on 3, and the other button is on the plus side max

Dear Sir/Madam, I purchased 2 units from for 2 different homes. However, I need help with the issue in the instructions that I have pasted below: "5.0 DIFFUSER INSTALLATION 5.1 Siting the Diffuser Position The diffuser has a unique air throw pattern and it is essential that it is located correctly in the central hallway in single storey properties or in the ceiling of the top floor landing on 2 or more storey dwellings. The diffuser discharges air evenly in all directions along the underside of the ceiling. Speed Setting Minimum distance of diffuser from wall 1 100mm 2 155mm 3 400mm 4 625mm 5 850mm 6 1000mm" I did not see these rules before my electrician installed the unit. However, he installed it with 200mm clearance to the walls in 2 directions, and over 1000mm clearance to the walls in 2 other directions. He then used the enclosed "air dams" to block off the 2 sides that had only 200mm clearance. My questions are: 1) Can I run my fan at speed 6 based upon the fact that the 2 sides from which the air flows have more than 1000mm clearance to the walls? 2) If not, what is the maximum speed setting that I can use on such a diffuser? 3) Is it advisable to leave the 2 sides with 200mm clearance blocked up or should all 4 sides be unblocked?

Hi, I notice you answered someone with 'and you have ventilation in your bathroom and kitchen and the loft is ventilated then this unit will do your application', however our bathroom does not have an extractor fan, will the PIV still work?

Do you have anyone who could look at my property to see if this can be fitted and is suitable please ?

i have a stone cottage in cornwall - the drimaster seems perfect to reduce damp and condensation in the house. We have a subfloor - about 1m deep and ventilated poorly with airbricks - this is very damp. would the loft mounted drimaster also help in the subfloor or should i buy a second unit to suck air from the house and direct below the suspended wooden floor thanks ben

Hi, can you extend the length of the ducting? If so which one would you recommend. Thanks

In a new build property, if installing this is it still necessary to install bathroom extractor fans?

hi why have these units gone up from £340 to 410!! this has basically priced me out of this product.

2 fitting questions. Our upstairs has dropped ceilings below a loft (approx. 18" void space below lathe & plaster ceilings). This makes access to the loft-side of the dropped ceiling very difficult. Can the diffuser unit be fitted from below (i.e. attach heater and ducting and wires working in the hallway) and passed through the ceiling hole assembled? We can then hook and pull through the duct and wiring to attach to the filter and motor. Secondly, can the ducting be extended more than the 2m supplied if necessary?

I currently have a standard drimaster and would like to change to a heated version, does the heated version diffuser match the dimension /size of the standard version as I obviously already have a hole cut in the ceiling and would not want to re-cut another hole if possible? Thanks

Hello Will this product be suitable for a 2300 sq ft house? Will performance be affected by the hall below the loft position having a glass atrium entrance to the house due to it being reverse accommodation?

can you recommend an installer for the CB6 area please

We have a 3 bed roomed detached bungalow with condensation and mold problems on a north facing wall throughout the property. We also have a new professionally installed boiler in a well insulated the loft space. The hallway is a good size but we would not be able to position the unit centrally because of a light fitting. Would we require a four way control panel as well? We are currently using a dehumidifier to solve the problems of condensation in the kitchen. It looks like the Nuaire Eco heat PIV product would solve our problems, please advise.

Does this product work with the rf controls?

Hi, In the winter we get terible condensation on 1 side of the house which is a thick stone outside wall. Its bad in 2 of the 2 upstairs bedrooms. We have a big house with 8 bedrooms in total all with en-suites. My questions is would this system work if placed in the landing ceiling even though the doors to these bedrooms are closed at night time and in the day and sometimes? Just wondering how it would work or if we would need 1 for each of the bedrooms that are a problem? I am then concerned that cold air will be being blown into these rooms so would need the heating on 24/7? thanks in advance

Hi there, I was wondering if this unit could service a house 3000sqf?

Hi I moved into a two bed Large bungalow 2 1/2 years ago we decorated it through out but in the first winter we noticed mould so I bought and installed drimaster eco heat which I set at 4 and over a period off time has worked well but we are now noticing the wood work round the doors and skirting boards are shrinking and cracks appearing in the plaster we do now the place was done up before we moved in have I had the unit set two high and over a period off time it has dried the place out

We live in quite an exposed location. Does the unit generate sufficient pressure to push damp air out in a location like ours when the wind is often blowing against the house or would a more powerful unit be required?

Hi, I am interested in the nuaire drimaster eco heat PIV, my question is , my property is a dormer bungalow and the only position for the vent would be in the ground floor hall. Would having a room above the vent effect the efficiency of the unit?The rooms I want to improve are on the ground floor. regards Andy

hi can these units be fitted by one's self if so will it affect the warranty

I have major problems with condensation which after reading the reviews, I think this unit will eliminate. I have supplied my tenants with a dehumidifier which they are obviously not using! I would like assurance that my tenants will not be able to turn this unit off or down. Thanks for any help

Can I install buy fitting a plug top with 3 Amp fuse on the flex and plugging into an existing socket? Would this impact warranty?

Hi! Have fitted Drimaster Eco Heat about 3 weeks ago. Very positive effect on the condensation, so happy with that. But I'm concerned as the noise level from the unit has increased noticeably since the the install. It was hard to hear at first (I'm using setting 3-4) but now you can clearly hear vent humming in a landing. Any advice on reducing the noise level (unit is suspended in the loft) or diagnosing possible malfunction?

I'm currently fitting this at the moment and we have loft insulation with boards on top. Is it ok to put the insulation/boards back close to the unit or should we leave some clearance? (Not sure if the heating casing gets hot.)

Can I put this unit in cellar instead? Or do I have to have two units building is two story. I ordered a £9 unit to see if my place is dry I cannot remember what it is called but it was not in my basket when I paid. Please how do I get one so it can come with my Drimaster as I do not want to pay for delivery. When I put drimaster in basket you asked me if I wanted the gadget to tell dryness number and I pressed yes. Thank you Deanna

hi will the carbon filter upgrade kit fit this unit

Hi, is it possible to retrofit the remote control units to the older Drimaster Heat units? Or is a separate option available for the older models? Thanks.

could you please tell me why in summer months i get a horrible sewage smell around bungalow but in winter months this does not happen

Hi, I have an old Dr, however, wimaster unit which is now making a loud click noise so I think something has come loose inside. So I am looking at replacing the unit. I have a couple of questions and hope you are able to answer these for me. 1) My current unit is on the floor in the loft on some batons to raise it up, can this unit be installed the same way or does it need to be hung from the rafters? 2) The current unit has heat but this is on constant and not something I have ever adjusted, with the new unit can I set it and not have to change it? Thank you

I have ordered the basic Nuaire Dri master HC unit for our 3 bed bungalow to hopeful eradicate condensation. My query is would it be ok to position the unit above the hall ceiling approx 1.5metres in from the main front door as this is where we have a radiator and so the warm air from this can counter any draft from the unit and the cooler loft air. We have an L shape hall and the location would be adjacent a bedroom door and in line with mother but round the corner of the L from the main rear longe and kitchen. Thank you

Hi, Im a bit confused with all the different models available from Nuaire. Please could you confirm if this unit is compatable with optional remote control switch and the humidity sensor. That would be appreciated. many thanks, Tim

I have read previous questions and answers and see that you do not recommend the heated version in a house where the unit will be installed at the top of the stairwell as warm air will rise to the unit. My house has high ceilings and a loft, but I'm not sure that it will be occupied all year round, so may sometimes be unheated. In that situation should I buy the heated version or not? Many thanks

Hello. I finally fit my drymaster eco today. The moment unit start running start making squeaky noises. Also it sounds like motor rubbing inside against something. Is it any chance to replace main unit? Or repair it somehow? Thank You

Will the unit definitely cure condensation forming on backs of drawer units etc. Rooms are already well ventilated. No drying of clothes indoors and no tumble dryer indoors. My contractor wants nearly £1000 to fit your unit and don’t want to spend that sort of money if it doesn’t definitely solve the problem.

If installed with loft/floor boards, judging by the photos the heating element would clash with the loft boards. Is it possible to extend the tubing between the diffuser and heating element to avoid cutting out more of the loft board than needed? I am also thinking about servicing needs in the future and just in case the element requires replacing it would be better to avoid lifting floor boards.

How can this reduce humidity inside the home during wet days/months when the humidity outside is much higher than inside?

Is it acceptable to position the landing smoke detector on the bottom of the ceiling diffuser? I have heard this is an option on other units, but the installation instructions do not mention it?

do i have to switch a heat button on or is it automatically heated

Hi I have one of the Drimaster eco heat models and the 4 way switch installed . Is the heater switched ON when the orange led is illuminated or does the orange led just mean that the heater circuit is enabled ready to kick ON & OFF according to where the blue thermostat control is positioned . I ask the question as I am conscious that the orange led being illuminated will be constantly running the heater element . Regards

What is the difference between ECO-Heat-HC. model and the ECO-Heat-HCS model

Could you please let me know when this will be dispatched. When ordering it said next day delivery when in stock but didn't say whether it was or not.

Hi, our top floor bedroom covers the whole floor (no landing area). would this unit still be effective for the whole house?

Can this be mounted on a plaster/Lathe ceiling. I have 250mm between joists is that sufficient to install

Hi. Any idea what the heat recovery function it that the manual indicates please? Can you use the HC model without the 4 boost switch and add it later? An inline extractor fan (about 1.5m away) for the bathroom is in the room behind the hallway but that only comes on when the lights get switched on. Is this likely to stop the PIV flooding air to the rest of the house?

We would like to use your product in a rental property. The roof has a very low pitch which it is not possible to stand up in. Would this cause any problems with the operation of the unit.

How safe is this product with the heating element in terms of fire safety in the loft. Does it have a automatic cut-off safety aspect. I am worried about running a PIV with heating element when for instance you are away on holiday

what is the db noise of the fan in the Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater By Nuaire

Energy now being very expensive-how long should the Drimaster be switched on for? How much does it cost to run (say daily). Does it need to be on 24 hours to work efficiently? Thanks.

Hi there, I bought this a couple of weeks back and installed at the weekend. It's already making a difference - humidity has dropped within the house and the air just 'feels' better! Really pleased so far. Question though regarding the heater. Despite the temperatures being quite low the last few days, the air coming from the diffuser is cold. I've tried altering the small blue dial on the diffuser panel, but doesn't seem to make any difference. There was a kind of heater element smell briefly - like the element was warming - but the air still feels cold, the element doesn't glow as I would expect so not sure if it's working correctly. Is there some way/setting where I can 'force' the heater to kick in? Thanks for your help. Lee

Hi, We’re just getting around to installing these 2 PIV’s, one for our house and one in the parents, but only 1 came with a cord to install it from a rafter. Please can you confirm if the second one should also have come with a cord? Many thanks, Jonathan 07885998144

How long is the standard duct length on these products. Can the duct be added to if I need a slightly longer run?

Would your company offer the installation services? And will you have a site visit to the loft before I place the order?

Do the eco-heat and eco-heat with switch versions come with the PM10 filters or are they only PM2.5? Is it only the eco-heat-NOX that comes with PM10? Thanks
