Balancing seems to be one of the favourite topics in this forum so sorry to be boring but...

I posted before about balancing. Many helpful replies. I pretty much get it but one quick clarification if possible. I have only 6 rads with combi boiler.

TRVs are on all rads except bathroom.

When balancing system should both valves in bathroom be fully open for by-pass purposes or should bathroom rad be included in balancing? Will this still be all right when other TRVs are shut down?

Sorry to be thick.

Thanks

Nigel
