Hi
This might be a naive question but I'm no expert in these systems and was wondering if any one can help.
I rent a house which has an under floor heating system which is water based. The system is set up with a Vaillant combi-boiler which supplies hot water to a circuit for the taps and a circuit for the underfloor heating. Both these circuits disappear into a small storage tank so that it works in a semi-combi style, filling the storage tank first.
In the summer we turn off the heating for the floor circuit on the boiler but the floor nearest the boiler (kitchen area) still gets v. hot from the residual heating effect of the hot water ciruit(well this is my idea of how the floor is getting hot).
This gets pretty uncomfortable when the downstairs is open plan and the average temp is +30oC (French Alps, not Sarf London). What are peoples opinions on just closing the water circuits that are feeding the underfloor heating system (there are 4 pipes going into and out of the wall below floor level, with taps on the inlets). Is this likely to cause any damage to the boiler, storage tanks or underfloor heating? Like I say I have no experience of these systems so any opinions would be gratefully received.
Cheers
D.
