Mike-
Central Heating and Cooling (Woburn) measured the house... footprint, room sizes, window sizes, insulation, and hot water demand... they speced out the right size Lochinvar boiler... they actually mount the zone pumps, and Boiler/expansion tank etc on a board that is attached to the outside wall of the basement.... the pictures of their installs are great... they have been using these boilers for several years.... BUT their quote is substantially higher than Kirkland & Shaw (Burlington) who says Burnham Alpine High efficiency burners are just as well made & efficient and cost a lot less. Plus the Alpine is sold at cost by natl Grid and installed by your local heating contractor... the Lochinvar is not available at cost thru natl grid.
