Description
Air to Water Heat Pump R290 RH Series
A Heat Pump That Thinks Before It Runs
Unlike conventional systems, the RH Series is built around energy-aware operation. Instead of reacting only to temperature demand, it evaluates:
- Real-time PV generation
- Battery storage availability (BESS)
- Electricity tariffs and grid signals
- Thermal demand of the building
This allows the system to shift operation toward maximum self-consumption and minimum grid dependency.
This positions the RH Series as a next-generation energy aware heat pump system, not just a heating device but a core component of intelligent energy infrastructure.
Designed for PV and Battery Integration
The RH Series is engineered as a PV integrated heat pump system, enabling direct interaction with solar and storage infrastructure.
Key capabilities include:
- PV-responsive operation (prioritizing solar energy usage)
- Compatibility with battery storage systems (BESS)
- Load shifting to align with renewable generation
- Reduced reliance on peak grid electricity
This makes it ideal for solar-powered homes and hybrid energy systems.
Applications
- Residential solar homes
- Net-zero and low-energy buildings
- Retrofit projects replacing fossil systems
- Smart homes with battery storage
- Grid-interactive buildings
Integration within the Huawei FusionSolar Ecosystem
The Tongyi RH Series can operate within advanced energy ecosystems such as Huawei FusionSolar, enabling coordinated control between:
- Inverters
- Battery systems
- Smart meters
- Heat pump operation
This integration allows the heat pump to function as part of a fully optimized energy management system, rather than a standalone appliance.

With increasing grid regulation (e.g., demand response frameworks), the RH Series supports grid responsive heat pump operation.
Features include:
- Demand-side flexibility
- Compatibility with smart grid signals
- Load modulation under regulatory frameworks
- Preparedness for evolving EU energy policies
This ensures long-term compliance and adaptability in regulated markets.

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.
