Hi
I have an existing old gas boiler, pump, and vented cylinder. I am looking to feed in a small multifuel boiler to add heat to my 7 radiators to enable me to cut down on gas bill. The boiler I am looking at is a 7 kw to water (5kw to room). My existing total radiator capacity is 8kw, which is warm enough.
My question is, if I have a 1.5kw heat sink radiator in the bathroom above the multifuel stove, could I have it so there is an `option` to turn the pump on when required when the rest of the house needs warming,,, or would the pump need to be constantly running to distribute the heat. my objective is to not have the pump running all the time due to the cost of running it.
Thank you for any advices.
