Description
Air to Water Heat Pump R290 RH Series
If you are looking for an air-to-water heat pump designed for the realities of today’s energy systems, the Tongyi R290 RH Series represents a clear step forward. Built around native HEMS logic, this generation goes beyond temperature control to actively manage when and how energy is used. The system continuously adapts its operation based on real-time energy conditions, enabling energy-aware heating and intelligent prioritisation of self-generated power. With PV-responsive control at its core, the RH Series transforms surplus solar electricity into usable thermal energy, reducing grid dependency while maintaining stable comfort and high seasonal efficiency.
This isn’t just another heat pump variant — RH stands for a shift in how control is designed. In the Tongyi R290 RH Series, RH combines the proven R290 platform with native HEMS intelligence, upgrading the control architecture rather than the mechanical core. It is not a cosmetic rename, nor a new hardware generation, but a smarter operating logic that allows the system to respond to energy availability, self-consumption opportunities, and grid conditions. The result is a heat pump that moves beyond simple temperature control, operating as an energy-aware system component built for modern, PV-integrated homes.

Explore the mechanism of an Air-to-water heat pump's operation.
An air-to-water heat pump functions by absorbing the latent thermal energy present in the air, which serves as the primary heat source. Through a refrigeration cycle, the heat pump employs a compressor to increase the captured heat’s temperature and transfers it to a water-based system. This heated water can then be utilized for space heating, as well as domestic hot water production.
