Ive opened a can of worms by researching the heating system for our refurbishment. We are having a central heating system installed. The proposed boiler is a Vaillant ecoFIT pure (think 618 but not definite). The heating will have 3 underfloor heating circuits for two zones. Builder intends...

I have just bought a house with a Vaillant ecoTec 637. The previous owner had some terrible Honeywell system installed but took all the controllers. So I can’t control the system, and in particular I can’t get the hot water on, no matter what I do. I had previously used a tado system, so I have...
