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 AHRI-Certified efficiency.
