4. Boiler Water Preheating: Reduces Boiler Fuel Consumption by Up to 30%
For hybrid systems integrating boilers, the heat pump serves as an energy-saving preheater. By raising incoming water temperatures to 40–50°C before it enters the boiler, it reduces the boiler’s workload, cutting fuel consumption by up to 30%. This synergy extends boiler lifespan and lowers emissions. The system’s PLC-controlled modulation ensures seamless integration with existing boiler setups, optimizing energy use without compromising performance. Ideal for industries relying on large-scale hot water production, such as hotels or hospitals.
5. Adaptability for Year-Round Energy Savings: Meeting Diverse Heating and Cooling Demands
In summer, it switches to cooling mode, providing efficient air conditioning. In winter, it delivers robust heating. Its modular components (e.g., water pumps, valves) allow customization for specific applications, from single-family homes to multi-unit buildings. By reducing reliance on fossil fuels and lowering operational costs, it offers a payback period of 3–5 years.
