Looking through this group. It seems there is always someone asking
about combi boilers and more......
Someone said that I need to get building regs invovled if I'm
replacing my current hot water tank and boiler
If this really needed ?
Afraid so. New installations must meet part L requirements for heat
conservation.
Also gas and oil boilers are controlled items anyway and so have always been
under BCO control.
I am in a similar position myself at the moment, scoping out a new
combi system for self install. From what I have read about the
building regs, my understanding is that they basically mean:
o TRVs for all but one rad / room
o Roomstat in the final location to switch boiler on and off and
minimise
short cycling
o Boiler has to meet minimum efficiency value
Is there anything else "significant" in there?
Time and temperature control of the HW.
Stored HW cylinders to meet PArt L (insulation or cylinder and hot pipework).
