Well, the new boiler (radiators) is a "super high effiecent" model. Low mass
boiler, heats only 2.5 gals of water, then an indirect hot water tank. Yes
there are some modifications, such as re-plumbing my garage errr SHOP for
more effiecient use of the water to heat my 2160 sq ft. Thats just the shop,
(eat your heart out). Thats only the first est. others are coming in this
week. So far I have had three companies out to give me estimates.
