Heat Recovery

Heat recovery is a technique for maximising efficiency by making use of heat that would otherwise be wasted. A heat recovery unit is a highly efficient water heating system that can cut annual hot water costs in half compared to conventional electric resistance water heating. A Heat Recovery Unit "recovers" heat exhausted by a central air conditioner or heat pump and uses it to heat water. This process supplies hot water virtually for free when the air conditioner or heat pump is cooling. It also supplies hot water at one-half the conventional cost when the heat pump is heating. The recovery unit does not produce hot water when the air conditioner or heat pump is not in use.

EMMCo Proudly offers the Doucette line of Desuperheaters.
