The Efficient Home Forum

I have some work being carried out on my CH system early January and I was wondering if range rating a combi boiler is still of benefit if running Evohome and Opentherm on the boiler side?

I only ask as it's something I could have done at the same time but I obviously don't want to do it if it's not necessary when using Opentherm.

Thanks in advance for any input.

Yes range rating is of benefit to OpenTherm, because the OpenTherm Bridge recalibrates based on the new kW figure you have rated the boiler to.

Thank you very much for the reply.

I will add it to January's jobs.
