I disagree it is unlikely. It all depends. 15% is the difference between 5.8kw and 6.7kw, so maybe a 7kw machine would be OK for both levels of heat l...

I haven't heard any discernible noise from the internal parts of my system, which is a Vaillant. Admittedly, I have no buffer, but I doubt they are no...
I would think this would be beyond the skills of most householders. My install just finished and it took them about 25 person-days and having observed...
Yes, Vaillant. But Aira were willing to give me that if I paid an extra £1k, which would still have been cheaper than HG. To be fair, a chunk of the ...
Just to round off some loose ends from my contributions to this thread, in the end I decided not to go with Aira. I realised that the various compromi...
