I am considering conversion from oil to gas. I have questions about optimal boiler for my existing radiator system. I have looked at the Burnham Alpine 150 (through local gas company offer) versus more conventional cast iron unit.
- 1982 well insulated 3200 sq ft house in Southern New England
-120ft of 1/2 in slantfin copper baseboards.
- Heat loss calculation 73,000 BTU/H.
I have concerns about the need for higher water temperatures with my current radiators and wonder if the lower operating range of a mod con will be effective. My current oil boiler runs at 175-195 deg.
In looking at a non mod-con unit - I am told I will need to line my chimney w/ SS vs Aluminum which given the course of the chimney may be more expensive than using PVC direct vent for mod con.
1) Given present radiator/housing specs - is a mod con boiler appropriate? If not what would you recommend.
