Hi,
I'm moving into a bungalow that has a 7 year old back boiler and tank working flawlessley. We will be adding 2 showers, 1 bath, 5 radiators and a towel rail once extension is completed.
To enable staging of the work (we will be living in the house while doing the work) I was thinking of keeping the back boiler and adding a separate combi-boiler.
The question is - what do i run off the combi and what off the existing back boiler?
