Combi boiler work without heating pressure?

thehound · 1 Aug 2019

Is it possible to make a combi boiler work to heat water when the heating system is drained?
My radiator changing project is taking longer than planned and the family would like some hot water!!

It’s a potterton 24 eco HE

Any ideas gratefully received.

Many thanks.

Basically no... you need at least one radiator on and the boiler and fad filled and pressurised.

Alternatively, you could cut into flow & return pipes, rig up a temporary loop under the boiler and pressurise it that way.
