Heat Recovery Valve Options

UL Listed Refrigerant Heat Reclaim Valves
R410a, R22, R134 & All Common Refrigerants

The HotSpot engineering team has developed heat recovery and heat reclaim valve and controls options for a wide range of water and fluid heating applications. Our valves are manufactured for refrigerant heat recovery, dual condensers, parallel condensers, and various refrigeration condenser waste heat recovery applications.

The right valve is never right without the proper system design, controls, sensors, solenoids and related accessories like coils and check valves, etc. Make sure to review your application with one of our experts. The valves provided by HotSpot are UL Listed and designed specifically for refrigeration, air conditioner or heat pump heat recovery applications. We provide these valves as part of complete waste heat energy recycling systems used for pool or aquarium heating (or cooling), hydronic heating, boiler pre-heating, domestic water heating, etc.

Hotspot heat valve for heat recovery applications



When working with most heat recovery applications, you are essentially providing a secondary condenser to capture heat that would normally be wasted by an air cooled condenser. It is important to have a design that evacuates the unused condenser, to make sure that no refrigerant is left behind.

Above: Internal design of one of our heat reclaim valves. One port always connects to the compressor discharge, one port always to suction. The other two ports are used to alternate between two condensers. The operation of the valve is governed by the controls logic established for the application.

A typical heat recovery installation will use one or more heat recovery valves, one heat exchanger, and a properly configured control system.


Heat Recovery Valves for condensing in corrosive fluids (like water with chlorine or saltwater) are typically used with a water cooled titanium heat exchanger. Other valves are available for heating potable water above the condensing point, to obtain higher temperatures, for example to make domestic hot water. Systems for this purpose are called desuperheater heat recovery water heating systems and are available for residential and commercial applications.
