Many thanks! Coat cupboard sounds like a good idea. I was thinking of having the manifold in there as well. As for smart controls. most probably I will go with tado https://support.tado.com/en/articles/3487152-how-does-tado-control-multi-room-heating-setups-with-a-combination-of-radiators-and-water-based-underfloor-heating and something along the lines of option no 2. Looks pretty straightforward.

Hmmm thanks for the photo, very helpful. This makes me think that such a buffer tank will fit. Can it go to the space under the boiler or does it need to be fitted high?

Thanks Nick for your advice. I don't think I will be able to use a buffer tank, but I will have another look and try to include it. Walls are insulated, however not the floor so this will be part of the process. It is suspended timber floor and most probably I will use PIR for insulation. Definitely I will keep reading the various threads to find useful information

Hi everyone! Nice to meet you. Just bought my first property, a 1930 semi detached two storey house. I am planning to retrofit wundatherm underfloor heating on the ground floor and leave radiators on the upper floor. The house has a combi boiler. I want two zones so the radiators will work independently of the UFH. What is the best way to connect them? Is just a zone valve before the manifold enough? Most probably I will get the Honeywell evohome or the tado V3 smart thermostat. Anyone had the above setup and use any of these smart systems? Many thanks, Zen
