Absorption-Heat-Pump/Boiler Systems

Using renewable energy to achieve thermal efficiencies of up to 145 percent in commercial buildings

Condensing gas-fired hydronic boilers have become increasingly popular in commercial heating applications during the last 20 years. Several models of condensing boilers now have thermal efficiencies approaching 100 percent at low firing rates and return-water temperatures. However, the 100-percent level remains the fundamental efficiency limit for hydronic heating systems in the commercial-buildings sector.
