KairHeat Recovery Silent Extractor Fan with Humidistat, Pullcord, Night Sensor - Anti Condensation Ventilation Unit

What a great unit. Fitting it was slightly tricky, but once done it really is superb. The air coming in is slightly cooler than that of the room, but I can't feel any draft underneath, nor does the room get noticeably colder. It also works just fine in very windy conditions, which was a major argument made against these units.My only gripe is the size of the humidistat box, which is rather large and heavy, but it is very worthwhile. Run a bath for 10 seconds and it detects the humidity and goes onto boost.Just great. Also everything was top quality.ONE WORD OF WARNING: The pipes/outer cowling will not glue using solvent glue, which is what the instruction manual called for. - they just don't melt the way they should. I had to turn to Araldite to get the outer cowl to stay in.

We initially had damp issues in 2 upstairs bedrooms. We had a damp expert come out and survey our house and there was a couple of issues.1. Our loft insulation wasn't thick enough AND wasn't spread out far enough so the walls were freezing cold in winter therefore helping the damp. We got this sorted with a few Wickes trips and help from my boyfriends dad.2. We needed air vents in those 2 bedrooms to promote air flow. Nothing fancy, just a plain, non-electric vent. We sorted that for around about £100 - £1503. He said our kitchen oven good extractor fan was more for show rather than efficiency, and said that's the case with most of them. When cooking a lot of wet heat and moisture come about and can go through the whole house, so we now always cook with the kitchen door closed and kitchen window open, still have the oven good extractor on when boiling and frying anything on the hob, and have this running in the background 24/7.You can set it to different humidities so that it's not on the high setting all the time (it's a little noisier than the general setting but it's not loud, you can hear but you just get used to it).Either way, after all 3 steps, we no longer have damp or little blobs of mould!

Installed it. Awful. So loud all the time; you can hear it from 30 metres away. Will be removing immediately

Installed this unit 2020 in the kitchen. I have not objective measurements but it seems to be doing its job. The humidistat level wanders a little so I have to change the threshold very occasionally (winder/summer), once set it manages itself, turns on when the kettle or the hob is on and turns off after its dried the room out. The transformer unit that includes the humidistat and override pull cord is rather old fashioned looking. It is quite expensive but a damp house costs you money heating. Despite the aesthetics and cost t I'm considering buying another for the shower/bathroom.

It turned out not to be quite the perfect thing for my particular application.I wanted this to reduce the humidity in my garden outhouse, mainly so I can store my guitars there without the potential hazard of wood swelling issues.It's my music room and I use it only a couple of times a week.Although I was advised this product works equally well in heated or unheated rooms, my experience is that it requires a certain amount of heat in the room to work at its best.Being a garden outhouse, it's not much warmer than the outdoor temperature when unheated in there.I don't really want to waste money heating a room 24/7, I obviously only want to heat it when I'm using it.I was hoping this unit would keep the humidity down no matter the temperature, but it appears to work more effectively when the room is heated, as I guess it extracts that heat from the outgoing air and applies it to the incoming air, so it doesn't really seem to do what I need the rest of the time, ie when unheated (when I'm not there!)To be fair to the retailer I-Sells, they have been excellent in their communications and I want to thank Ted and Connor in particular for their attentiveness and efforts in trying to reach a resolution to help me resolve the issue and I thoroughly recommend the company in general and Phil for talking me through the process on the phone and offering a site visit.Great guys who provide an excellent and genuine customer service.I happen to live only a few miles from their showroom and was able to visit on a couple of occasions, both times the sales guys were extremely proactive in working with me in trying to find a resolution.But I think perhaps my scenario (cold unheated garden room) is not a common one so perhaps no one foresaw that these conditions may be a stumbling block to the effectiveness of the unit.In a normal room in your house at normal room temperature, I'm sure it works absolutely great.Also, although it's fairly quiet, I wouldn't call it silent and I still need to switch it off when recording with mics as they pick up the gentle whirring in the background.Certainly quiet enough for a bedroom I'd say, just not when working with microphones (another uncommon scenario no doubt...!)To be fair, my research hasn't brought about any other product that can do what I need, so I'll continue to work with this the best I can for now.

Does what it says on the tin. We have it in our main bathroom and we leave the bathroom door open all day so it's helping ventilate the bedrooms and landing. I've looked at it with a flir camera and it doesn't get cold on cold nights. Don't point it at the shower though. Its easy to wire and yes the cover falls off the end of the pipe if you don't use something like tec7 and a couple of screws. The 6 inch hole saw recommended further down will take all day to drill a hole for this. Pity it's not quieter, I'm tempted to fit one in our kitchen but the noise puts me off.
