Questions and answers of the customers

Hi. I am considering purchasing one or more of these and was wondering if you install these. If not, who would I get to do it?
-
A Hi Katie, Thank you for your question, We do not do installs and are supply only, a qualified electrician would be able to install the unit for you. We could possibly offer someone that can instal the unit, where abouts is the property? Kind regards,A
Hi Katie,
We could possibly install these depending on where your property is located. If you are not close enough then you should have a qualified electrician to install the units.
Kind regards,
Hello, would this be suitable for a 40m3 kitchen please? Dimensions are 5.3x3.1x2.4 (lwh). The extractor would be towards the end of the room (extracting from one end of the 5.3m length). Thank you
-
A
The airflow capacity of the Kair Heat Recovery Extractor Fan is typically between 40-60 m³/h for single-room units. This is significantly below the required airflow rate for a 40 m³ kitchen.
the Kair fan is not suitable for a kitchen of this size because it cannot provide the required ventilation rates.
Consider a kitchen-specific extractor fan or a centralized heat recovery ventilation system with a capacity of at least 400 m³/h.or a 60 L/s fan
you could try this nuaire extractor on our website i-sells.co.uk you can give me a call on 0208 463 9518

Does this unit have a continuously run function? What is the range of humidity sensor please? Would it suit 6m by 6m open plan kitchen/family room?
-
A Good afternoon Natalia. All Heat recovery units run continuously. This unit will run on a trickle speed and boost via humidity or by pulling the pull cord. The threshold for the humidity sensor is between 20-90% but we recommend setting it between 50-55%.It will be suitable for the living space, but the kitchen will need to have a separate extractor fan ducted to the outside. Kind regardsMarc
Hello,
We suffer from lots of condensation and black mould spots in our bedroom each winter. These grow around the window frame most densely, as well as on curtains and blinds, the exterior bedroom walls (of which there are two) and also any furniture positioned in the coldest areas of the room.
Previously I was advised to open a window to allow the damp air to escape, but this doesnt work and is also very cold in winter months. I have tried to remove with damp spray each week to try and limit the problem but this is just a quick fix.
This year we have a new baby (currently 3 months old) so need a solution and am hoping the Kair Heat Recover Extractor Fan would work. Im not sure if this is the right product as I cant see anything about mould in the questions above, just condensation.
Many thanks in advance for your advice.
-
A Hi Lauren. Give me a call on 020 8463 9514. I do go to lunch between 1.30 and 2.30, but am available until 5.30, and from 8 am tomorrow morning.Kind regards, Marc
We need to improve ventilation and control humidity in the kitchen. The only feasible access is through the wall to the adjacent garage. An extension of about 1m would then allow access through the garage wall to the outside, but I understand it is not possible to duct the kair unit. What would you suggest
-
A Good morning Mike.You could look at something like the Airflow QT150HT extractor fan. These can extract over long duct runs, and it comes with an inbuilt humidity sensor.We currently have 1 in stock.Kind regards, Marc
We had the fan fitted recently but the night sensor was not activated. Could we activate it ourselves or do we need to get an electrician to activate it? In either case, please tell us how to do it as I cant see anything about it in the instruction booklet. Thank you.
-
A Good Morning JanetThank you for your question. A Light Level Sensor is included to prevent the fan from switching automatically to boost at night time.This is a useful feature particularly if the Heat Recovery Ventilator is installed in a bedroom or bed-sitaccommodation, ensuring noise is kept to a minimum.The sensor is factory set in the OFF position as this is preferred for most installations. This meansthat the automatic boost feature will operate if the humidity rises during the hours of darkness. Toactivate the light sensing feature, (boost inhibited during darkness) turn the adjuster fullyanti-clockwise, shown on page 2.This should be an approximate setting for most installations depending on the location of the remotetransformer/humidity assembly in the room.Fine-tuning may be required for precise operation, especially in rooms with low energy light bulbs:- Clockwise allows boost to operate during darkness- Anti-clockwise prevents boost operating during darknessA simple test for the correct setting is to trigger the boost feature via the humidity sensor in adarkened room. When switching the light on or off, the boost speed should cut in and out accordingly. Please come back to me if you require any further helpKind RegardsAnita
Hi, we have a small 2 bedroom terrace with upstairs bedroom. We currently experience high levels of moisture from the bathroom, adults and child sleeping upstairs and kitchen cooking and clothes drying downstairs. Is there a way I can understand the right number of units as really keen to purchase, but want to right-size the requirement. At the moment, I think I would like one unit in the kitchen downstairs, and one or possibly two upstairs. Im uncertain about the upstairs as the house is small, hence the question. Once weve come up with the right number of units, it would also be great to see if you have any recommended suppliers in the East of England? Many thanks for any help
-
A Hello JamesThank you for your enquiry. Please give me a call on 0208 463 9683 and I will be happy to talk through your requirementsKind ReagrdsAnita
Hi there, is there an adaptor for using this in a single skin wall (approx 215mm + plaster)? I.e. something to secure the overlap of the 345mm shaft...
-
A Hi Ed, and thanks for your question.Sadly there is no adaptor, as these units are really only suitable for wall thickness between 229mm and 356mm, or up to 1m with the extension.If your wall isnt quite thick enough, you may need to create a box section on the inside, being careful not to affect the airflow of the unit.Kind regards, Marc
Are the controls manual and is there an off switch?
Thanks.
Ruth
-
A Hello RuthThank you for your enquiry. The pin wheel to set the unit is on the fan and the pullcord if the fan needed to be boosted is on the transformer. This fan is designed to run continuous however if you have windows open in the summer then you can turn the unit off. If you have any further questions please do not hesitate to contact us.Kind RegardsAnita
We had one of these heat recovery extractor fans fitted in our conservatory a few weeks ago in order to cure the condensation problem that we were having . I must say that although the unit was on boost for a couple of weeks it has sorted out the problem. The only thing is even with the radiator on the unit seems to be blowing out cool air , I thought that it should circulate the warm air in the room. The unit is on the opposite wall to the radiator if this makes any difference. I look forward to your early reply.
-
A Good morning Bill. The incoming air wouldnt necessarily be hot air, as it does rely on the exhaust air warming up the heat exchanger. That in turn should warm the incoming air a little bit and should save quite a bit of heat loss. Its possible the air around the unit on the inside is not warm enough to heat up the heat exchanger enough. This would be more prominent when it is very cold.Kind regards, Marc
What is the noise/decibel level of the product when switched on at the different output levels?
-
A Hello Joseph, Trickle speed 21 decibels (youd hardly notice it unless you put your ear up to it and everything around is quiet) and then 45 decibels on boost speed (which you will hear but in theory its only on that when it needs to boost the air circulation to bring the humidity level back down or if the pullcord is pulled). The trickle and boost are dependent at which level the humidistat dial is set at (ideally between 40-60%, it comes set at around 50-55%) but you can easily adjust this yourself so this will also determine how often the machine goes from trickle to boost itself.Hope this helps, Ingrid
Hi, this would be for a kitchen, so I dont really need SELV. Do you do such a version?
Thanks,
David
-
A Good afternoon David. Take a look at part number KAIKSRHRV100-WHKind regards, Marc
Thanks for aswering my question ive opened it up and the fuses are missing can you tell me exactly what fuses they are please
-
A Hi Don.To the top left of the circuit board you will see two fuse positions, one labelled ‘fast’ and one labelled ‘slow’. The reason for this is toallow adjustment for long cable runs. Make a note of which positionyour fuse is in before replacing and make sure your new fuse goesback in the same place.These units use a 5A quick-blow fuse.You may also want to check the fuse on the fused spur.There is a diagnostic PDF in the download section on out website. If you look up k-hrv150 and click on the HRV unit itself and scholl down a bit, you will see it. Info is on page 2.Kind regards, Marc.
unit not working at the moment are there any fuses that may have blown and can be replaced
-
A Hi Don. There is 1 or 2 fuses in the transformer itself. It is likely one of those have blown. Please make sure you replace it with the same type and amperage.Kind regards, Marc.
I have been waiting to purchase this item for several months but havent because its not a stock item, I have noticed that it is due in stock on 6/12.21. If I place an order with you now will you debit my account with the full purchase price on the day of purchase or 2months from now when the item is dispatched?
-
A Hi Mark, Thanks for your email.Yes sorry the units have been in high demand and limited supply recently due to component shortages.To secure a unit within the next available batch you would need to pay now rather than when the unit is dispatched.I hope that helps to answer your question.RegardsChris
I would like to install a Single Room Mechanical Ventilation Heat Recovery System in my bathroom, but the only reasonable way of connecting to the outside air is through the roof. Is it possible to do this, rather than going through the wall? Can your heat recovery unit be used with a standard roof vent tile, or is there another way?
-
A Good afternoon Ben, and thanks for your question. This unit is only deigned to go directly through the WALL. The only units that can be ducted to tile vents are the Blauberg Komfort D105-A and the Vent Axia HR100R / HR100RS. The tile vents will need to be at least 300mm apart, preferably 500mm to prevent the duct runs from contaminating each other.If you want to discuss options, you can call me on 020 8463 9514 Mon-Fri 8am-5.30pm.Kindest regards, Marc.
One of these units has been recommended for installation in a second floor bedroom to cure a condensation/mould problem. The unit looks suitable to cure the problem but I am balking at a quote of £700 to purchase and install one unit. Is this reasonable?
-
A Good morning Ted, and thanks for youre enquiry. Prices will differ from installer to installer, so it might be worth shopping around. The installer will need to do a few post installation checks to make sure the unit is working how it should be. You could buy the unit yourself, and shop around for someone to install it. That may save you some money. We dont have stock available at the moment until the middle of May.Kindest regards,
Hi, old mid terrace house, no cavity walls, small damp cellar under front room only from inadequate ventilation. do you think this fan would be able to ventilate the cellar sufficiently and dry it out ? the air would be expelled a little above floor/ pavement level- but from head height in cellar. i am thinking it would fit in air brick site under the floor.. would i have to block up any other air brick in cellar for best effect ? previous owner had blocked up air bricks [ idiot ] so i need to sort it quickly.i am guessing size wise the kit would fit the wall thickness. many thanks , rob
-
A Good morning Robert and thank you for your question. To be honest, there are some variables that need to be considered. Has the cellar been tanked? What size is the cellar? Length x Width x Height. Also, is there any kind of heating down there. For Heat Recovery to be effective, it would require some heat to recover, or you could just be bringing in cold air. If you want to give me a call on 020 8463 9514, I can go through some options with you.Kindest regards, Marc.
Hi. This item is out of stock wherever I look. Do you know when it is likely to come back into stock at i-sells.co.uk? Thanks
-
A Hello GeraintThank you for your question. The next due date we have is the 12th April. I would recommend placing your order now so your order is placed on back order and allocated when the stock arrives. If I can help any further please do not hesitate to contact meKind RegardsAnita
Can you tell me if I will hear noise from the outside. My outside wall backs onto the back of a shop who have a large and noisy air conditioning fan running 24x7. I have the windows closed to stop the noise, hence the condensation....would this unit transfer the noise into the bedroom ?
-
A Hello GrantThank you for your question. It is a possibility that you would hear some noise within the room. Is the property a house or a flat as I maybe able to spec another unit for you.Kind RegardsAnita
We are looking for individual heat recovery fans for a bathroom and a kitchen.
The bathroom measures 2.2x1.6x2.5m. The kitchen measures 5.0x2.3x2.6m. What would be suitable for each room, especially the kitchen since according to your (very useful) air exchange guide, the kitchen would require a massive air exchange rate (299 l/sec !?). Also, can an ordinary electrician install individual heat recovery fans?
-
A Hello MarkThank you for your question. The HRV150 heat recovery unit will do your bathroom application but will not do the kitchen due to the size. You can however install a continuous running fan or a humidistat fan in to the kitchen. Please see below two product codes for two options of fans. If you have any further questions please do not hesitate to contact meCV2: QS12424Kair Smart: QS50879Kind RegardsAnita
Hi, I will shortly be installing a large dehumidifier for a pool room and this dehumidifier will do the required dehumidification. Im thinking of getting this Kair heat recovery unit simply to provide ventilation, but keep the incoming air warm. The room is 9m x 7m x 2m. Will it be suitable for this purpose?
-
A Hello ShaunThank you for your question and sorry with the delay. Please give me a call on 0208 463 9683 and I will be happy to talk through your requirementsKind RegardsAnita
Would your K-HRV150 unit be suitable for an 8ft by 11 ft garden room that has rather thin walls? The walls are breeze block with insulation and plasterboard on the inside and render on the outside, so the total wall thickness is just a bit over 15 cm.
-
A Hi Colette, I have answered this on the original format
Is there a requirement for an internal or external condensate drain. Does the unit as sold for £286 come complete with the transformer/humidistate or does this need to be purchased separately
-
A Hello RogerThank you for your question. Everything you need comes complete within the box there is no requirement for a condensate drain on this unit. If I can help any further please do not hesitate to contact meKind RegardsAnita
Is there a maximum room size where this fan should be fitted
-
A Hi PhilThis a good question and depends on the room designation.For instance, is more than capable of dealing with (and keeping dry) a domestic wet room which would be approx 2.5x2.5x2.5.Place it in a bedroom of larger proportions it works fine but there is no moisture creation. Same to be said for an even larger open plan lounge / dining room.Probably not a good answer but tell us the application you are thinking of and we may be able to help with advice.

Easy to order and swift delivery. I knew what I wanted and found the item quickly so ordering was simple. I received the item in great condition and was happy to give the project a tick.
(K-HRV150/12RH – Kair Heat Recovery Silent Extractor Fan with Humidistat, Pullcord, Night Sensor – Anti Condensation Ventilation Unit – HRV150)
Brilliant product. I got a bungalow of 8 flats in. In the past, every room has problems with condensation, humidity, mould. I tried many things to help combat this problem. However, every time I visited my tenants, i always felt the room air is humid and not having fresh air. I know opening the window could be solution but in winter time, no one like to do it.
I got 2 Kair to try first after speaking to Marc, I could felt the difference of air in the room. The room became less humid and the air has been fresher. After trying for 2 rooms, I decided to put the rest with this fan. The job was done today, I was very pleased as the air in all the rooms are really nice not like before. I highly recommend this product. Because the flat is self contained, so I was worried about the noise. Kair is very good as in normal mode, I hardly hear anything but when it is boost mode of course the noise is stronger but it will trick back to normal mode when the humidity is at set level. To install it is a bit hard as the old fan hole is smaller so we need to make it bigger but our electrician did it for us very well.
Thank you so much to Marc for giving useful advice and selling such a good product like this.
Info about this product on the website looked straight forward but when the product arrived and looking into the instruction booklet for installation, it wasn’t straightforward and we had to seek advice to get info on how it should be installed. It’s quite fiddly. Took much longer than expected and so costs me more due to time taken with electrician. It is now summer so not really using it. I just hope it will work during the winter time to prevent condensation and mould.
An excellent product which hopefully will expel any moisture to prevent mould growth on a stairwell where it has been installed. My only gripe was installing it from the inside only as there was no access to the outer wall. (stairwell to flat a flat) Not as easy as was claimed; therefore only 4stars
Does not blow cold or even cool air at you, very important in a bathroom setting. Pretty quiet but not silent. Very efficient, especially considering the price.
