This has most likely been asked before but I can`t find a specific answer from searches so a bit of guidance would be appreciated.
Recently moved house and some of the c/h rads are in desperate need of replacement.
I`ve got a combi boiler supplying the rads and dhw on demand and the new rads are of a different size to the old ones so in need to move some pipework etc, but my question is:
if I drain the c/h system only will the boiler still supply the dhw when needed?
Any help appreciated.
