Hot Water Heat Recovery System
Get Free Hot Water...
From Your Air Conditioner
HotSpot is a low cost, hassle-free heat recovery unit (HRU) that recovers heat energy to make free hot water.
HotSpot recovers concentrated high temperature heat from your air conditioner's condenser circuit and pumps the recovered heat directly into your hot water tank.
Heat recovery provides an excellent return on investment for residential customers located in areas where the air conditioner is running the majority of the year. It will provide free hot water heating during the season that the air conditioner operates. To see what annual percentage of free water heating you may be able to obtain, see Cooling degree days data chart for locations in the U.S. (US 48 only.)
Air conditioner users benefit with free hot water during the cooling season. Heat pump users can obtain free hot water during the cooling season, and also save up to 70% on water heating costs during the heating season. Users in climates like southern Florida and Hawaii can get free hot water all year long. HotSpot operates day or night, rain or shine, with no panels on the roof & is maintenance free.
A HotSpot recovery unit connected to a typical 3.5 ton air conditioner running 5 hours per day can recover more than 34,000 BTU, enough to save about 10 kWh of electricity per day.
HotSpot water heating recovery units are simple to install and are complete pre-configured systems including pump, controls, heat exchanger, and 140F automatic upper limit safety switch. UL Certified & Made in USA.
Upgrade any air conditioner, large cooler or freezer, or heat pump system into a source of free hot water.
By far, waste heat recovery is our most popular aftermarket solution because it can be located directly adjacent to the compressor without regard to the tank location.
It connects to one or two compressors and can connect to any hot water tank.
Remote units can be installed indoors or outdoors, on the roof, or wherever the compressor is located. That means that the refrigerant lines can be very short and the system is quite simple to install.
Freeze-protected for outdoor installation.
