Now i know its a electrical engineering group but plumbers are electricians with their brains kicked in arnt they
I am considering installing UFH in a bathroom, the arear to be warmed is 8 square meters my plan is to run the boiler flow pipe (22mm) to two
zone valves one of which runs the whole houses radiators and the other is to run to the bathroom in 22mm where it is reduced to 10mm JG speedfit for the UFH loop and back on to the 22mm return to the boiler.
The boiler is Worcester 28i junior (non condensing) and brand new.
after the pipes are in it is to be tilled
My question is by reducing it to 10mm will this provide sufficient heat
restriction so as I dont have the full heat of the boiler on the floor tiles?
i.e. I dont want to cause them to crack through thermal shock.
I am not a qualified plumber but have a few years of experience in domestic systems
Thanks for any advice
