I have an old oil hot water furnace and I was wondering if I could reduce the amount of time and duration it fires up if I added a hot water tank before or after it? My father in law has a newer, multi zone one and I noticed he has a hotwater tank beside his. I noticed his doesnt come on as often as mine does.
My old one is dude for replacement in the next few years and I was also wondering in what way a new one is better?
