Hydronic system delivers comfort, efficiency
Wilfre Company Inc. was referred to the owner of a 4,500-sq.ft., bayside home whose existing heating system wasn't sufficient when the wind kicked up. Air-to-air heat pumps were the primary source of heat, with hydro-air coils and a large condensing boiler as a second stage. Wilfre disassembled the existing system in September, when the heat pumps would have no trouble satisfying any call for heat. The new 210 MBH Burnham Alpine condensing boiler was hung on the wall, along with a US Boiler Sage Zone Control and a Grundfos ECM circulator for each of the two zones.
