hi, I'm struggling to get my head around what kw boiler to fit for customers who need a combi. I've never had to survey a job (normally done by someone else).
I've read that a rule of thumb is 1 lmp = 2.5kw
So I've tested my own home and I have 18 lpm from the main and 9 lpm from the hot tap. The boiler I have is a eco tec pro 28 and works fine, but isn't the boiler undersized? I've checked the cold valve under the boiler, it hasn't been closed down but I'd aspect some restriction through the plate/boiler.
Any advice will be appreciated.
