Two questions actually - A few years ago when we bought our home, we got a new Bradford White Aerotherm water heater that has a heat pump. Told its very efficient.
What they did though was have the incoming water come through our oil furnace and radiator system - and the furnace keeps the water in there heated pretty high - it comes on now and then for a couple minutes. 24/7. But we turn it off in the summer - we are in Maine - so this is really a winter concern.
We were told that it was set up this way so that if there was alot of hot water demand, the heat pump would have water already heated from the furnace. Two things about this - its just two of us, rarely if ever is there a lot of hot water demand - its a pretty big tank too- but more important why would I want my less efficient oil furnace heating my hot water that goes into the way more efficient brand new hot water heater?
Second question - in the winter, when the heat is coming on more, is it more efficient to have the furnace coming on and off to keep the water that will circulate to the radiators warmer?, or just let the system turn on and off from the thermostat which means the water is being heated from a cooler temperature?
I am also going to speak to the heat pump company. Thanks for any help.
