When deployed as a Heat Pump Water Pump, it circulates heat-transfer fluid between the evaporator and storage tank, preserving the COP efficiency advantage of heat pump water heaters. Its 85°C maximum medium temperature rating matches perfectly with most residential heat pump and solar thermal systems.
Ideal application scenarios include domestic hot water recirculation, solar water heating systems, gas and wall-hung boilers, underfloor heating loops, and small commercial installations such as cafes and salons.
The Hot Water Boost Pump outperforms traditional AC pumps with its BLDC motor — saving $100–$180 over 5 years, operating at ≤45 dB, and delivering ≥2,000 hours of brushless, maintenance-free performance.

It is equipped with G1/2″ or G3/4″ threaded fittings, compatible with pure water, tap water, and up to 50% propylene glycol antifreeze. It requires horizontal shaft mounting and an external DC power adapter, fitting all common water heating equipment including tank, tankless, solar thermal and gas boiler systems. The 36V version delivers higher head with lower current for long pipe runs or multi-story homes, while the 24V version suits solar and off-grid setups.
The product is CE/RoHS compliant with a 1-year manufacturer warranty and installation guidance. It is safe for potable hot water when installed per local plumbing codes. Annual maintenance only covers inlet screen inspection, seal check and impeller descaling in hard water areas, with no brush replacement or lubrication needed.
