Hi,
I have an old 15 year boiler, but don't belive it is worth it to upgrade due to the payback time required. I currently have no TVR's. Is it worth installing? do they really save money?
I understand they shut of radiators but the boiler will still work until the thermostat turns it off?
Another question, are triple radiators more efficient than double or just produce more heat due to more surface?
