I am new to this site and to heating with anthracite coal. I purchased a Alaska Channing III direct vent in the late spring and I am attempting to install a hot water coil.
My question is how large of hot water heater would I need for a family of 5 ?
I have been searching for a used one on craigslist and have come across quite a few good used water heater for short money but most of the units are under 50 gallons and I am trying to find at least an 80 gallon tank (thinking that more is better).. If I cannot find one of that size, would I be able to run 2 smaller tanks, say a 40 gal or 50 gal tanks in tandem?
Any help would be greatly appreciated.
