Heat Recovery Water Heating - Free Hot Water From AC/Heat Pump

Domestic Water Heating image of heat recovery unit water heater A full range of HotSpot retrofit heat recovery systems is available for any size AC, heat pump, walk-in cooler, walk-in freezer or other refrigeration system with a capacity from 1 ton to 100 tons. Commercial and residential models available. HotSpot heat reclaim water heating systems can pay for themselves very quickly.  MORE>>>

Get 100's or 1,000's of gallons of free hot water every day

Heat recovery water heating pays for itself very quickly using free waste heat from your
AC or refrigeration compressor to heat water and cut your water heating and/or pool heating costs.

HotSpot heat recovery water heating units remove waste heat from any refrigeration compressor and recycle it directly into your hot water system, reducing or eliminating the use of purchased energy for water heating. At the same time, improve the efficiency of your air conditioning or refrigeration system by up to 18% as you remove the excess heat. (Up to 40% electrical savings with pool heating model.) Domestic water heating units are independently tested and certified to assure health, safety and verified performance.

Established in 2007, HotSpot engineers have a long history in HVAC, solar, and heat recovery design, development, and manufacturing. Our engineers have developed dozens of cutting edge energy products sold by us and by others under a variety of brand names. HotSpot heat recovery systems convert any refrigeration compressor into a source of free thermal energy to make hot water, using the same initial amount of energy input. The waste heat recovery system also makes the compressor system operate more efficiently and the compressor will use less electricity when the heat recovery unit is active. Waste heat energy recovery domestic water heating systems use a desuperheater for water heat recovery, sometimes called a waste heat exchanger. The heat recovery units are designed for waste heat recycling in order to convert a standard boiler into a heat recovery boiler.

HotSpot also uses a special titanium heat recovery heat exchanger along with heat recovery valves and controls for heat recovery pool heating, the HotSpot pool heaters convert the AC to geothermal technology to heat a pool while increasing the AC efficiency at the same time. HotSpot titanium heat exchanger pool heat recovery units can heat pools with no additional energy to provide a free pool heating system.

HotSpot products are mostly based on saving money through air conditioning efficiency, heat recovery, and solar power. HotSpot also proudly distributes next-generation LED lighting as a way to help customers further cut their energy bill.

In 2012 HotSpot released its 3rd generation solar air conditioning/solar heat system for indoor cooling, heating, or AC augmentation. The ACDC12 is a one ton solar AC heat pump achieving a SEER 35 rating with two solar panels connected and that can provide >80% savings on daytime air conditioning or heating costs. HotSpot also provides an all-DC telecom or solar air conditioner. From 2016 HotSpot is the master distributor (USA) for Chiltrix air-to-water heat pumps offering record-setting AH RI-Certified efficiency.

Solar Air Conditioning

Our team invented the DC solar air conditioner and essentially created the solar AC industry with the development of our first solar AC unit in 2006.

The current model DC48 is version 4.2 of our original 2007 model.

In 2009 we developed the world's first "hybrid solar AC", the ACDC12 which was released in 2010. The ACDC12B came along in 2014. In March of 2018 we released the ACDC12C and the ACDC18C. Many thousands of ACDC12s and 18s are deployed in the USA and around the world.

From Q1 2018, the HotSpot ACDC12C and ACDC18C units define the state of the art in PV-direct solar AC units, now allowing a 100% solar-only experience backed up with extra power pulled only as-needed from the grid and seamlessly blended with solar when the sun is not strong enough to fully run the unit on solar. It runs fully on the grid at night.

During the day, it can run with no AC power connection.

And as with all versions of the HotSpot DC48 and ACDC12/18, no inverter is hidden inside the unit. DC power from solar is directly used.

We are the first, the largest, and most reliable provider of solar AC units. Often copied but never duplicated, you can trust HotSpot Energy to deliver the world's highest quality solar air conditioning products.

HotSpot Energy also produces the Solar AC / Heat Pumps for others under various private label agreements.
