NULITE New Energy has recently completed an air source heat pump installation project in Bishkek, Kyrgyzstan, providing space heating and domestic hot water for a 350m² villa.
The project was developed with a particular focus on the local electricity supply conditions. For some residential properties in the area, the available electrical input power is limited, and the customer for this project required the heating system to operate with an input power of less than 10kW. This requirement became an important consideration when selecting and configuring the heating system.
To meet the customer's needs, the project uses an R32 10P air source heat pump, together with a 200L buffer tank and a 300L domestic hot water tank. NULITE heat pump systems support frequency limitation, allowing the operating frequency to be adjusted according to the customer's requirements. The applicable setting can be adjusted within a range of 0.3–0.9, providing greater flexibility for projects where electrical capacity needs to be carefully managed.
Under the rated A7/W35°C condition, the R32 10P has a rated heating capacity of 35kW, an input power of 8.1kW and a COP of 4.32. These figures are based on the specified rated test condition and are provided as a reference for equipment selection. Actual operating performance varies according to outdoor temperature, water temperature and system demand.
For this Bishkek villa, electricity availability was an important part of the customer's decision to adopt a heat pump system.
The property has a floor area of approximately 350 m² and requires both space heating and domestic hot water. At the same time, the available residential input power needs to remain within the customer's specified limit.
Rather than treating power capacity as an afterthought, NULITE considered it as part of the overall system configuration. The heat pump's frequency limitation function allows the operating frequency to be adjusted according to the requirements of different projects. Within the applicable setting range of 0.3–0.9, customers can select an appropriate setting based on their available electrical capacity and operating requirements.
This flexibility is particularly relevant in markets where residential electricity capacity is limited or where customers need to manage the power consumption of heating equipment within an existing electrical supply.
The approach also reflects a broader consideration in heat pump system design: equipment selection needs to take into account not only the heating requirements of the building, but also the conditions under which the system will actually operate.
The project is located in Bishkek, where outdoor temperatures in the project area range approximately from -9°C to 32°C.
The NULITE R32 10P is used as the main heat source for the villa's space heating and domestic hot water requirements.
The heating system includes a 200L buffer tank, which provides additional water volume for the heating circuit and supports the connection between the heat pump and the building's heating system. An external circulation pump is also installed to support water circulation between the heat pump, buffer tank and building heating circuit.
A 300L domestic hot water tank is also included to meet the household's hot water requirements. The heat pump supplies heat to the DHW tank through its heat exchanger, allowing the same heat source to serve both space heating and domestic hot water.
The resulting system provides a centralized heating and hot water solution while taking the property's electrical capacity into consideration.
The Bishkek project provides an example of how heat pump solutions can be adapted to the practical conditions of the local residential market.
For customers in areas where household electricity capacity is limited, the electrical requirements of heating equipment can be an important factor when evaluating different heating options. Flexible operation can therefore play an important role in making a heat pump system suitable for a particular property.
NULITE's frequency limitation capability provides customers with an additional way to adjust heat pump operation according to project requirements. Combined with appropriate equipment selection and system configuration, this allows the heating solution to be considered from both the thermal and electrical perspectives.
Through projects such as this one, NULITE continues to gain practical experience in Central Asian markets and to better understand the requirements of local customers and installation partners.
As heat pump applications continue to develop in Kyrgyzstan, NULITE will continue to provide solutions that take into account local climate conditions, electricity supply and installation requirements, supporting customers and partners in implementing practical heating and hot water systems.
