This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids. Combustion source fuel types including natural gas, propane, digester gas, diesel fuel, and No.2-6 fuel oil are all heat sources which can be retrofitted with Cain heat Learn More
System Function Cain boiler economizers reduce energy cost by capturing valuable heat from boiler combustion exhaust that would typically escape up the stack and into the atmosphere. This recovered BTU is transferred back into heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol and thermal fluids.Learn More
Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil.Learn More
