OK - Advice pls.
I want to accomplish 2 things maybe with one system.
I would like to out baseboard hot water heat into a basement I am finishing. I would like to use natural gas. One zone is fine, multiple zones would be gravy if it didn't add too much to the cost.
I also want to upgrade my hotwater heater to a 50 gal or larger.
My existing HW heater is 40 gal NG with a powered vent out the side of the house. I figure I need a 50 or 75 gal HW heater to supply enough hot water to fill a large soaking tub.
Here is my ideal setup, if something like this exists.
A single boiler that will supply heat for the baseboard and serve as an on demand system for domestic hot water. This boiler would be able to exhaust in the same way that the existing HW heater does (3" PVC out side, horizontal, of house).
Alternatively A storage tank with this set up would be my second choice. 3rd choice would be to keep domestic HW and baseboard heat totally separate.
Any thoughts? Thanks in advance
