The age old question: zone valves vs circulator pumps
We decided on a boiler and an installer. The contractor has recommended that we replace our 4 zone valves with circulator pumps. I am somewhat against this as I feel that the zone valves are more energy efficient. I can certainly see the benefit of the circulators but fear that my electric bill will be $30 or so higher during the winter months. $30 isn't going to make or break me but doesn't it defeat the purpose of upgrading to a more efficient boiler? Connecticut has one of the highest electric rates in the country at something like $0.23 per KW. Am I over reacting? Would 3 additional pumps use much more energy than zone valves?
As always, your help is appreciated.
