I moved up to New England from Florida about six years ago. Until that point, my only experience with hot water boilers had been when I was in the Service, many, many moons ago.
Well, during my time up here I have heard that water circulator pumps should be installed on the return side of a hot water system and I've also heard that they should only be installed on the supply side.
The thing is - I haven't really heard a good explanation as to the Why of it, either way. I'm hoping that one of you will be able to give me an answer as well as a bit of insight about why it should be done one particular way and not the other.
Thanks in advance for the help in this.
Ps. Give me a Heat Pump/Gas Furnace system any day! Heh.
