Furnaces and Boilers | Department of Energy
Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.Learn More
Optimizing Efficiency for Boilers and Thermal Fluid
Feb 05, 2016 · (See table 1 for a sample chart or perform an Internet search for "gas efficiency charts.") For steam boilers, an efficient and durable design is a four-pass, water-backed, scotch-marine boiler. "Four pass" means that the hot gases from the burner travel the length of the boiler four times before exiting.Learn More
