Be aware it can only be used under certain floor types too. For about a third of the cost you can fit standard under tile electric UFH at the outset and if you don’t want to use it, just switch it off ... I think there's more to it than normal LV UFH. It only heats up where it's needed. If the sun is shining on a patch of floor that patch will not heat. Link to comment Share on other sites More sharing options...

It doesn’t care if the heat is from the electrical resistance or from an external heat source, it will self regulate. It’s the same technology that has been used in trace heating tape for years.

I will go back & question BPC a bit more. They are my preferred option. I will ask them to put me in touch with an installer. Does anyone have any other ideas for a supply & fit? Hello how did you get on with bpc? I’m thinking of using them. thanks. Link to comment Share on other sites More sharing options...

Moira Niedzwiecka Posted February 12, 2018 Share Posted February 12, 2018 @Luckylad Sorry not to respond before. I have not had a chance to look into this further yet. Lots of other more urgent stuff going on. BPC have always been helpful in the past. Link to comment Share on other sites More sharing options...
graeme m Posted February 14, 2018 Author Share Posted February 14, 2018 I'm now looking at the Nilan Compact P system. I like everything in one box. Ducting is blooming expensive though. http://www.nilan.dk/en-gb/frontpage/solutions/domestic-solutions/compact-solutions/compact-p Link to comment Share on other sites More sharing options...

I used plastic ducting which has worked well. Link to comment Share on other sites More sharing options...

Gone West Posted February 16, 2018 Share Posted February 16, 2018 14 minutes ago, graeme m said: How does the warm air heating work? Is the only heating you have? It has a built in EASHP which heats the water and heats the ventilation supply air up to 40C. That is supplementary heating because we also have electric towel rails in each of the three 'bathrooms'. These are 300W but are turned down to around 200W and are on eight hours a day. The heat from these is recovered and heats the supply air. We are not living in the house yet but it's kept at around 19C/20C. The Genvex Combi185LS has worked well for us so far but ours is a very low energy house.

I don't know if that is overkill or not, sounds like it might be to me. Do you have to use their ducting, so it would invalid a warranty if you don't for instance.

stratman90 Posted February 20, 2018 Share Posted February 20, 2018 Anybody experience in dealing with Beam when it comes to MVHR? I'm getting a quote this week from them. From the sound of things it sounds like I need to speak to BPC too! Link to comment Share on other sites More sharing options...

Power consumption is 6 watts slow speed, 12 watts on mid speed, and 48 watts on boost! Runs on slow speed continually and boost when required humidity is very comfortable. Filters are easy to source and replace around £20 a set. Link to comment Share on other sites More sharing options...
