This portfolio presents examples of Tongyi residential heat pump installations in European markets, including Latvia, Germany and Poland. The projects illustrate how air-to-water heat pump systems can support space heating, cooling and domestic hot water across different homes and climatic conditions.

System configuration varies according to each building’s heating demand and installation requirements. One featured installation combines a Tongyi heat pump with a 300-litre hot-water storage tank to provide a dependable supply of domestic hot water.

• Example System Configuration

  • Hot-water storage: A 300-litre tank is used in one of the featured residential installations.
  • Heat-pump technology: The featured installations use Tongyi R32 air-to-water heat pumps for residential heating, cooling and domestic hot-water applications.
  • Applications: Depending on the project configuration, the systems can provide space heating, cooling and domestic hot water.
  • System design: Heat-pump capacity, storage volume and operating temperatures are selected according to the building’s heating demand and local climatic conditions.
  • Performance: Actual efficiency and electricity consumption depend on the selected model, outdoor temperature, water-flow temperature, system design and user demand.

Installation Considerations

System sizing
Each heat pump should be selected according to the building’s calculated heat loss, required water temperature and domestic hot-water demand.

Climate and operating temperature
Outdoor design temperature and the required heating-water temperature influence capacity and efficiency. Correct sizing is particularly important in colder European climates.

Hydraulic integration
The final configuration may include a hot-water storage tank, buffer tank, underfloor heating or radiators, depending on the property and installation design.

Installation quality
Correct hydraulic balancing, insulation, commissioning and control settings help the system operate reliably and efficiently.
