cost effective options to heat a small temporary space.

[speedystu]

Boiler pump, these systems are not generally used for UFH, but for radiator systems, I can's see why they can't be used that way, the mixing of the boiler water to cold water to maintain the correct temperature in the pipes (approx 45deg) would need careful adjustment as it would with a conventional system, you will need a large diameter by-pass to prevent local overheating, are you going to use the boiler to indirect heat your water.

I will work with a local plumber to get it all right but looking at the auto mixing valves on the manifold seem like the perfect way to keep the temperature regulated for ufh, the boiler would heat the water for ufh but , I suppose if the boiler was big enough it might be able to heat hot water for separate storage too? I really only had the immersion heater in mind before you told me about electric boilers thank you! I got quotes for heat pumps, they are too much for this budget build first up.hence trying to think of a civilised and budget way around it. Heat pump in the future just not yet
