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.
Like all renewable energy water heaters, including solar or heat recovery, the industry best-practice is to use a pre-heat design. This is especially important when working with high-SEER or variable speed AC or heat pumps.
