Overview: Why TONGYI R290 Stands Out Among European Residential Heat Pumps
As the EU pushes strict F-Gas phase-down rules, net-zero residential targets, and widespread rollout of rooftop PV, battery storage and EV chargers, homeowners and installers demand heat pumps that balance eco-friendliness, high efficiency, and full smart energy interoperability. The TONGYI HEMS Optimized R290 Smart Heat Pump is engineered specifically to meet European market requirements, combining natural ultra-low-GWP refrigerant, AI energy decision logic, open industrial protocols, and seamless coordination with solar, storage and electric vehicle infrastructure.
Unlike generic air-to-water heat pumps that only deliver basic heating and hot water, this unit acts as a core node of your whole-house energy ecosystem. It automatically shifts operation to surplus solar windows or off-peak tariff periods, boosts on-site energy self-consumption by over 30%, and supports virtual power plant (VPP) dispatch to generate extra grid revenue for households. With a compact footprint, it fits urban balconies, utility cupboards and small garage retrofits—perfect for old European apartments and new passive houses alike.
Core Green Advantage: R290 Natural Refrigerant With GWP=3
Unbeatable Low Carbon Footprint Complying With EU F-Gas Regulations
Refrigerant global warming potential (GWP) is now a non-negotiable standard for EU heating equipment:
- R290 (propane) GWP = only 3
- R32 GWP = 675
- R410A GWP = 2088
TONGYI’s R290 circuit eliminates high-GWP fluorinated gases, helping property owners hit local carbon reduction benchmarks without sacrificing heating power. The seasonal COP reaches up to 5.33, translating to drastically lower electricity bills year-round, even during cold winter ambient temperatures.
75°C Maximum Hot Water Output For Radiator Retrofits
A common pain point for European boiler replacement projects is low water temperature from standard heat pumps, which forces costly radiator upgrades. This R290 smart heat pump delivers stable 75°C outlet water, directly compatible with existing cast iron radiators, high-temperature domestic hot water circuits, and industrial heat recovery setups. It maintains consistent heating capacity under harsh low-temperature outdoor conditions, removing renovation barriers for older homes across EU countries.
8 Key Intelligent & Interoperable Product Advantages
1. Open Protocol Compatibility – No Proprietary Vendor Lock-In
Native built-in support for mainstream European smart energy bus standards, no additional gateway hardware required:
- EEBUS, Modbus RTU/TCP, M-Bus, KNX, REST API

This open architecture avoids closed system limitations, a critical feature for installers designing flexible smart home energy setups.
2. Full-Chain PV + Battery + EV Charger Dynamic Linkage
The unit’s HEMS decision core runs real-time surplus photovoltaic tracking:
- Detects excess solar generation instantly
- Prioritizes heat pump operation or thermal hot water storage
- Coordinates EV charging schedules to maximize self-consumption
Independent testing verifies a minimum 30% lift in household self-consumption ratio, cutting grid electricity reliance and monthly energy expenses significantly.
3. Grid-Friendly Functions: TOU, DAM, VPP & DSR Smart Dispatch
Built-in grid interaction engine designed for European liberalized energy markets:
- TOU Time-of-Use tariff auto-optimization: Runs heat pump during low-price valley hours
- DAM Day-Ahead Market price response: Adjusts load based on next-day electricity pricing
- VPP Virtual Power Plant dispatch: Participates in grid flexibility services to earn household incentives
- DSR Demand Response millisecond-level signal reaction: Automatic peak shaving & valley filling
Homeowners gain dual savings: lower daily heating costs + passive income from grid balancing programs.
4. Native Huawei FusionSolar Ecosystem Integration
Exclusive seamless compatibility with Huawei’s full solar product line: inverters, power optimizers, residential battery storage.
