谷歌来的，新锅炉为啥高效

A high-efficiency furnace saves money because of two major developments in furnace technology:

• They have two heat exchangers instead of one, so the condensed gas is converted into heat instead of being expelled through the exhaust as in older models.

• They use sealed combustion, where an air-intake pipe brings the air required for combustion from outside rather than using open combustion, where warm air from inside the home is heated (like with older models).
