i am going to try to keep my central boiler running all summer to heat my domestic hot water. i by passed my heat exchanger and now the central boiler runs through my side are on my hot water heater. i am concerned with the unit running all the time and the electric consumption i have the bigger pump talco 014 which uses 1.7 amps unlike the 007 that uses .70 amps that most of you use on your boiler. i was thinking about putting the talco on a in line timer and only running the pump around dinner time to heat the hot water back up. what do you guys think about this? and do you think its a overkill ?
