HYBRID ENERGY SOLUTION

The BLUEJOY Hybrid SPA Heat Pump incorporates a sophisticated electric heating control program, engineered specifically for spa heating systems. By seamlessly connecting to your spa's electric heater via integrated relay, it delivers a true hybrid heating solution and elevates the user experience through consistent, reliable performance. Besides, optional PV direct-drive module increases energy saving from 80% up to 98%, delivering maximum efficiency with minimal cost.

40℃ HOT WATER AT -25℃ AIR TEMPERATURE

Versus traditional heat pumps, BLUEJOY Hybrid SPA Heat Pump (UItra-low Ambient Temp.) integrate Enhanced Vapor Injection (EVI) technology, enabling stable 40℃ hot water output at -25℃ ambient without auxiliary heaters. Meanwhile, comprehensive anti-freeze systems and full thermal insulation ensure reliable cold-climate operation.

INSENSIBLE DEFROSTING

Compared to traditional SPA heat pumps, BLUEJOY Hybrid models integrate dedicated control terminals for electric heaters. During defrost cycles:

▶Instant heat compensation activates to maintain water temperature.

▶Defrost time gets reduced.

SG & HEMS CONNECTIVITY

Enables unit connectivity with national smart grids and PV system to support energy conservation under expanding energy-saving policies.

Heat pumps are controlled by smart meter or home energy manager signals to maximize household photovoltaic energy utilization.

Operational Intelligence:

Heat pumps are controlled by smart meter signals to maximize household photovoltaic energy utilization.

Reduces energy expenses through dynamic load optimization.

Compatible with energy storage expansions:

▶Electrical Accumulators

▶Thermal Batteries
