Actually I like that idea as all 3 UFH manifolds have a return electrical feed which powers the boiler ( there is no main circulation pipe just a pump for each circuit ), thus the pipe stat can be put in series and the water heating circuit can rely on the boiler stat. Talking to Warmflow...

From practical experiance the higher temp you put into the blending valve the lower return temp of the boiler return as most of the return feed is diverted into the blending valve which as the input is high temp then slows down the input flow which then means all the extra heat you have created...

Its a Warmflow HE, and yes did ask, return of 30 -35 OK by manufacturers, in practice the return is about 30 -32 so sought of working OK. Heat needs to be only 38 reaching the floor to give good even heat with a floor temp of about 25. Would just be nice to keep the boiler working in the...

Yes the boiler is a high efficiency ( oil boilers don't really condense )requiring allowing slightly lower than normal returns plus each under floor zone has its own temp blending valve but to run the boiler to 50c rather than say 80c for most of the time would save quite a lot of fuel over a...

We have an oil fired boiler which has a basic high level thermostat which is ideal for heating the water cylinder ( a few hours per day ) but we have also an underfloor heating system which requires a lower temp water ( most of the day). Does anyone know of a dual temperature thermostat ie one...
