HP21405T | Hayward HeatPro MCHX 140K BTU Heat Pump

Hayward HeatPro 140K BTU Heat Pump

The Hayward HeatPro HP21405T 140K BTU Heat Pump delivers top-tier performance and energy efficiency using advanced microchannel heat exchanger technology—an industry first for residential pool heating. This innovation enhances heat transfer, reduces refrigerant use, and makes the unit lighter and more compact than traditional designs, all while maximizing durability.

Improved Low Ambient Heating That Lasts Longer

Engineered with a patent-pending defrost algorithm, the HeatPro MCHX Series delivers rapid and reliable heating even in low outdoor temperatures. Its advanced microchannel design minimizes performance degradation over time—unlike traditional tube-and-fin systems—ensuring long-lasting efficiency and dependable comfort in any season.

Built to perform in demanding conditions, the HeatPro features a patent-pending defrost algorithm that improves heating efficiency even at temperatures as low as 50°F, extending your swim season with reliable comfort.

Best-in-Class Corrosion Resistance

Built to withstand the toughest conditions, the HeatPro MCHX Series features a TCP coating originally developed by the Naval Air Command. This advanced finish offers exceptional protection against corrosion, making it ideal for coastal environments and demanding outdoor climates.

Engineered for long-term resilience, the HeatPro’s robust coil structure resists physical damage during installation and operation. Its exclusive TCP coating—originally developed by Naval Air Command—provides best-in-class corrosion resistance for harsh poolside environments. The unit is also more environmentally conscious, using less refrigerant and producing fewer emissions. With lower panel loading requirements, it operates efficiently on 40-amp breakers for certain models, making it easier to integrate into existing electrical systems.

Simplified Design, Fewer Leaks

With an 85% reduction in braze joints compared to traditional heat exchangers, the HeatPro MCHX Series minimizes potential leak points—resulting in improved reliability, longer service life, and easier maintenance over time.

The HeatPro is proudly built and assembled in the USA and backed by a 5-year parts warranty. AHRI certified for trusted performance, the HP21405T offers powerful heating in a compact, rugged design—ideal for pool owners seeking both performance and long-term value.

Durable Coil Protection

The robust coil structure is engineered to guard against fin damage during installation and withstand outdoor impacts, ensuring long-lasting performance in tough environments.
