The DRI-ECO-HC enhances Nuaire's PIV technology with the added benefit of having the system controls located in the contemporary ceiling diffuser. This unique feature bestows the homeowner with complete control of the unit, without having to enter the loft space.
Not only can settings be altered with the push of a button on the contemporary diffuser, but there is also a 7 segment display which notifies the user of the need for filter change and what setting the Drimaster is running on.
The DRIMASTER-ECO range provides whole home ventilation using the Positive Input Ventilation principle, which introduces fresh filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.
A large range of models are available - Please see our table below. Please note, it is not possible to retro-fit a heater to other Drimaster Eco models.
It has become the UK's most popular alternative method of low energy, cost-effective ventilation!
Invented by Nuaire and installed in thousands of dwellings each year, PIV can be a more cost-effective and simple to install ventilation solution, whilst still meeting building regulations.
CREATES A HEALTHY LIVING ENVIRONMENT
MOISTURE AND CONDENSATION ARE DRIVEN OUT
The filtered air gently pressurises the home from inside out, forcing out the stale air.
NO NEED TO OPEN WINDOWS TO VENTILATE
Clean, fresh air is continuously drawn in through the lofts natural leakage points, passed through the filters and fed into the property via a central hallway diffuser.
Always get a qualified electrician for fitting the unit!
The unit is supplied with a pre-wired power supply. This power supply unit has a metal bracket incorporating fixing holes, which should be used to fit the power supply to a suitable surface, e.g. a wooden joist.
The fan unit is also supplied with a fused spur. The 3 core mains cable from the power supply should be connected to a fixed wiring installation, via the isolator, via the spur, in accordance with current IEE wiring regulations.

Once the Drimaster is installed does have to stay on 24/7 or only in the months when condensation is most common.
Hello,
My two storey, 4 bed semi, has a landing ceiling just over 3metres long but only 66 cm wide. Can I simply fit in the centre of the roof and dam the two sides closest to the wall so the unit vents "longways" in both directions?
Hello James
Hi just enquiring about the sizes my loft hatch is small 30cm by 54 cm do you do a drimaster that will fit through my loft hatch I live in a 3bedroom house thank you
Hello Elaine
Hi We suffer from quite bad condensation and I've been told these are the ones to go for. We have a 2 bed flat on the top floor (2nd floor) of a 1960 purpose build. Do you recommend which would be best? We have a large loft which would be able to accommodate a loft installed model. Thanks, Ian
Hi Ian
Hi would this help with asthma? My 4 year old little girl particularly struggled st night with coughing. This has been recommended. Thanks
Hi Katy
how often do you have to change them and what is the cost of them, also could you tell me the running cost per year
Hello William
Thank you for your question. The cost for replacement filters are £27.49+vat +delivery.It is recommended that you change the filters every 5years but in between you can wash the filters with luke warm water and they can also be hovered. The cost of running for this unit is approx.2p a day. If you require any further assistance please do not hesitate to contact me
Kind Regards
Anita
our loft is insulated with spray foam, will this unit still work, also is it suitable for a 3 bed semi? How much does it cost to run?
Hello Sheila
It looks like tile vents, ridge tiles, eaves, soffits have been sealed off, the work was done by warm and dry homes Ltd, by previous owner. There is a velux window, so could you suggest a unit that would be fine to use. Thankyou
Does your system remove diesel particulates and nitrous oxide or do you know of any sytems that do ?
Hello Sol
Sirs Please can you inform me if your company carry out supply and fit Thank you Mrs D SCIPIO
Hello Mrs Scipio
Hi, will there be any impact if doors are closed. We normally keep bedroom doors closed to keep cats out but it's the bedrooms where we really need the fresh air. I assume air will flow through gaps as internal doors are not a tight seal but wanted to know if there would be significant impact on the amount of air.
Hello Andy
Hi, just enquiring what area does 1 unit cover. In m2. I am building a new bungalow so all 1 floor. Thanks.
Hello Nigel
Hi Would this help with condensation in a loft space, the roof is well insulated and its a end house of 6 but does not have any eves was built around 1970 timber frame brick outside walls.
Hello Roger
The answer is No and Yes, so please bear with me!
The indication that you have condensation in your loft points to a lackof ventilation to the loft void, inspect from outside to see if you have slateor tile vents, or ridge tile vents, airbricks or soffit vents.
If there is no ventilation and you installed the Dri Master under these circumstances it would not controlcondensation in your house or the loft as the means of drawing air into thevoid are not sufficient for either.
The installation instructions for this unit begin with the loftinspection below.
Checkto ensure that the loft has adequate ventilation. There may be occasions wherea loft is so well sealed that additional ventilation may have to be provided bythe owner/occupier. Ensure that all water tanks are covered and sealed. Checkthat all water pipes are lagged. Ensure that any extract fans are dischargingto outside and not into the loft. Check that the loft hatch is tightly sealed.Ensure that all holes in the ceilings are sealed i.e. ceiling light fittingsetc
Oncethe loft ventilation has been increased or reinstated the installation of the Dri Master can go ahead and the throughflow of air to the void on the way to the dwelling will create air change andair movement causing surface evaporation and eventual drying of the void andthe dwelling.
How much does this cost to run . Would it have to be on 24/7 and is it nosey
If I buy the non heating model is there a way later on to have it converted to a heating one?
Hi Rowland
i have a 3 bedroom end of terrace ex council property, with a pitched roof suffering from mould everywhere, what model nuaire would you recommend
I suffer from terrible condensation on upstairs windows and walls in one room (the coldest, North facing). It is a four bedroom detached with a high stairwell, what would be the ideal model for me to maximise the benefits of the unit. Thank you
Hello Stuart
Where the system can be installed in a property with high ceilings the basic model is more than adequate and the heat version is unnecessary.
Hi How noisy is this product? Is it a low hum or the same noise as a dehumidifier?
does the product come with fixing kit
Hello James
Hi, I have a 3 bed bungalow with a good sized loft so size of unit isn't an issue. I am curious of which unit would be best for me. We suffer with terrible condensation in every room during the colder months and the bathroom gets black mould near the window reveals. The condensation is almost the entire window streaming with wet. We have double glazing and central heating which we have running 24/7 in the cold months with a min temp of 18deg. I am worried that the system will bring a lot of coolness to the bungalow whilst the heating is on and also I assume that each room has to have the door open for the system to work effectively? Is there a way around this issue? Any advice would be appreciated as I don't want another winter of drying windows and worrying about mould. Many thanks in advance,
Hello Paul
live in a semi detached 2 bedroom bungalow - 5 rooms & hall - which model do I need
The system was designed to be installed to take advantage of convection of warm air, that rises to ceiling level, in houses this would be the stairwell ceiling and the advantage if this warm air is not felt. For properties with lowerceilings and bungalows the heat option is offered to temper the incoming air to compensate for lower ceilings and reduce the chill factor during very cold periods, we should point out that it is not designed to supplement a home heatingsystem and temporarily increasing the internal heating thermostat would be a cheaper option than running the heater option for long periods. Please note that the system is also designed to work with and enhance the efficiency of mechanical ventilation in the bathroom and kitchen.
I have recently purchased one of these, and just had it fitter yesterday, I have a problem the speed control is not working, I called technical service and they are sending some out so it is presently just running on the max speed. But also I have noticed that the air blowing out is bring the loft smells down into the house, (not bad smell but smells different if you know what I mean) is there a solution to this
Hi Peter
The fact that it has only just been installed will be a contributing factor particularly if the loft was slightly damp as it now needs to dry out and the through flow of air will do this in a matter of 24 - 48 hours!
One thing to check is that the ventilation to the void is adequate as covered in the installation instructions. This is something you may need to ask your installer, ie where is the replacement air coming from? This could be slateor tile vents, or ridge tile vents, if there are none the loft ventilation mayhave been provided by overhanging eaves or soffit vents, if the last two,continuing problems can sometimes be a result of loft insulation being rolledtight into the eaves cutting off this means of airflow.
Oncethe loft ventilation has been increased or reinstated (rolling back the insulationat several points or installing sections of open ducting to clear an air paththrough it) the Dri Master will create air change andair movement causing surface evaporation and eventual drying of the void andthe dwelling.
Hi, I can see on the dimension drawing that unit is 820mm wide with filters. Could you please let me know what is the unit width without filters? (I have limited access to the loft) What is the diameter and length of ducting? Is it possible to replace ducting with slightly longer one? (I might require extra 1m) Thank you
Hello Tom
I am installing in a chalet bungalow (it has stairs and rooms in the roof, is it a bungalow or house? what a quandary). Anyway, question is if I start with this basic unit and then decide to upgrade to heat, can i buy the heater separately and reteo-fit to this model?
Hello Graham
i have breather felt to my loft with out ventilation would it work with this
Hi Steve
Hi, I have a 3 bedroom terraced house with hall and high ceiling. My concern is cold air (recently -8)being blown into the house that I am trying to heat. Thanks.
Hello Steve
You mention that you have high ceilings and this is an advantage, theunit is designed to introduce air at ceiling level and in houses, when heating isused, the warmest air naturally rises to ceiling height the stairwell isgenerally the highest point in a house and therefore plays host to some of thewarmest air in the dwelling, the benefit of which, is not felt. If the inputcan be located at this level the incoming air is mixed with the warm air, is tempered, andredistributed. During very cold periods the incoming air would be colder but generally we tend to increase the thermostat setting which deposits even warmer air at ceiling height to counter this.
If however you felt this was not enough, this recent version has the control settings accessible in the diffuser so during prolonged cold periods we are of the opinion that re-calibrating the input air rate temporarily to a lower setting would still provide the required fresh air but should not impact overmuch on comfort levels.
Our house is 3 storeys with the top floor (attic) converted to a bedroom (ie there is no loft space above the attic). Would it be possible to install the unit in the eaves to one side of the attic bedroom? This would mean the diffuser would not be in the centre of the landing ceiling but slightly to one side.
Hello James
I have two bedrooms upstairs but the highest place I can fit the dri master is on the half landing, would this be okay. Thanks
Hello Dave
I had this unit fitted last year and I understand my builder purchased this unit from i-sells website. The product did have an effect on my condensation but not entirely over the winter period. When I access the loft, mainly in summertime, I notice the unit is not on at all. Is this correct? Does the unit work intermittently as I was under the impression that it provided positive pressure at all times...Thank you in advance.
Hi Danny
Hi, I have a 2 bedroom flat and having condensation which is giving black mold appearing especially on the cable side of the property. the flat has a roof space and a stairwell. The top of the stairwell is a door which separates the flat from the stairs. Just wondering which unit would be best and also would I have to make the stairwell part of the flat by removing space at top of the door so as to permeate this space using this unit style
Hello James
I have had 2 Drimasters over the last 25 yrs but my current model has died. I'm looking at getting the Eco Hall Control Diffuser but note it has a circular diffuser (as opposed to the square one on my current model). What is the size of the circular diffuser as I don't want to get my ceiling touched up if I can help it.
Hello Theresa
My stairwell leads to a small landing (3 metres) one door to the left, one door to the right in a tee shape. It is one metre wide in every direction. Is it ok to put the vent at the top of stair well which is only 1 mtr wide just before it reaches the landing?
Hi Sam
Please can you give me an idea why the unit is making a continuous loud clicking noise. I have changed the filters but it still persists
Hello Paul
hi i have a narrow L-shape hallway which is 4ft wide.i wanted to fit diffuser a metre from front door,but ceiling has a roof beam right down middle of ceiling.as u turn right into second half of L-shape hallway there is a loft hatch then kitchen.i think i can fit diffuser just before lofthatch,as all doors are close by,is that ok?can u please tell me what will happen if diffuser is to near to near a wall,as i wanted to fit near front door as i have a rad which would mix the cold air,but one side of the diffuser would be near wall,so only other spot is near loft hatch. 1 last question,as unit draws air from loft gaps etc ,the soffit boards have been overclad with pvc and underneath is cement board which may or may not contain asbestos.if by chance the wind was to blow a fibre into the air would the filters stop it blowing into house.hope u can help regards
Hi Robert,
as i stated my bungalow has a narrow L-shape hallway as u walk in from front door,i wanted to fit 1 metre from front door in centre of 4ft wide ceiling ,but have a roof beam above ceiling board,so is it ok to fit near wall and fit air dam near wall side,i want to fit there as i have a rad which would warm the incoming air.the only other place to put is in second half of the L-shape hallway behind loft hatch ,as all the doors lead off there.hope u can answer both questions regards
Hello Robert
I suffer from running condensation in our upstairs bedrooms. We have a small hallway on the first floor which accesses all bedrooms and then extends above the stairs. What is the optimum position for the unit. On the landing the ideal location is outside of the main bedroom door but I am worried of a slight draught being felt. The other option is on the ceiling above the bottom stair. Would the unit be as effective at this location? If so I wont be able to access the controls on the unit from the hallway so will choose the version with loft controls. I also note this is a basic version is the |HC version more efficient?
Hello Brian
Hi,We live in a 3 bedroom detached bungalow built in the mid-eighties.I am getting condensation on the windows which is becoming a pain. (excuse the pun)I have had Envirovent to give me a quote but the cost for an Atmos system with a built in heater was more than I am looking to pay.Their rep said there was a good air flow in the loft and he guaranteed to get rid of the condensation problem.What would the Nuaires system with a built in heater cost me and does it come with full instructions.Also what is the length of guarantee for the motor.I look forward to hearing from you and would appreciate any advice. Thank you Bob Edwards
Hello Bob
Hello, 1,In the beginning of your video it mentions an average family produces 10 litres of water a day, where will this water go as its in the atmosphere? 2, If my family keep doors closed how can condensation be removed from their bedrooms etc?
Hello Stephen
Hi I have a 3 bedroom detached bungalow which used to be two semi detached the problem is , we terrible condensation in the bedroom and dining room , utility that causes mould , how much do these heat version cost to run .
Hi. The latest costs I have are about a year old, but it won't be far out. The cost for the heated version is aprox 10p per day. The Drimaster will certainly make a difference, and if you have an extractor fan in the bathroom, and preferably the kitchen too, then you should be free of condensation within 48hours. This is providing the loft space is well ventilated. We do always recommend the heated version for single storey properties, as there is less space for any warm air to rise.
Does this product remove the need for an external fan based ventilation system in bathrooms?
Hello John
Hi Is it possible to have a section flat ducting from the diffuser back to the main ducting. i would need to go under floor 1m approx. to get to the landing as i have a dormer next to the remaining part of my loft.
Hi Anthony and thank you for your question. By adding extra pieces of ducting you will be affecting the airflow. The unit and the ducting that comes with it, has been specially designed to give equal air flow throughout the day. Also, if part of the loft has been converted, you may need to add a couple of extra vent points for the Drimaster to be effective. The other option would be the Flatmaster unit. It is suitable for properties up to 100m2.
Been studying these as we have a severe condensation problem thru winter no matter how we live eg opening windows, never dry washing on rad etc etc but nothing ever changes - will these reach areas like behind beds cupboards etc? Are they guaranteed to work@ - we have trickle vents in every single window and a bathroom fan.
Hi angie, if there is a gap between the wall and the bed for instance then yes it should work as the airflow can reach behind it. If the airflow is blocked because the bed is too close then it won't.
I have a 2 bungalow with pretty bad condensation within the winter months is this product suitable to help avoid condensation? Also I see you have a heated version and if I find this version give off to much of a chill is it possible to buy the heater separately and fit to this version?
Good morning Ryan. Unfortunately you cannot retrofit the heater to the non-heated version. Being a bungalow, we would recommend the heated version, but please be aware, the heater is only 400w, so it will only take the edge off the temperature of the incoming air when it is cold.
Can you please let me know if this item is now in stock please ?
Hello Darren
Hi, I just bought a PIV unit after hearing excellent reviews. Do you think it would be more benificial to leave windows very slightly open to make it easier for the filtered air to push out the older air? Many thanks
Hello Sam
Hi there, The item has not arrived. Can you check on delivery status please? Kind regards, Jon
Hello Johnathan
What is the diameter of the flexible output duct of the Nuaire Drimaster Eco Hall Control unit
Good morning Alan. The Flexible duct is 200mm in diameter and is 2m in length.
How often should it be serviced and can any electrician service it or should it be a specialist? If the latter, can you recommend anyone? Thanks
Hi Conrad.
I am confused does this model have integrated heat, the comparison chart has this crossed out? if it does are all of the controls in the diffuser and can you turn the heat off completely from the diffuser?
Good morning Graham. This model does not have the heater.
