The NULITE R410A DC Inverter Split Air Source Heat Pump is a high-efficiency, all-in-one solution for residential heating, cooling and domestic hot water. Featuring advanced DC inverter technology, a Mitsubishi inverter compressor and R410A refrigerant, it delivers stable and energy-efficient operation in outdoor temperatures from -25°C to 43°C. The split system consists of an outdoor heat pump unit and an indoor hydraulic module, providing flexible installation and reliable performance. Compatible with underfloor heating, radiators, fan coils and domestic hot water tanks, it offers year-round comfort, intelligent control and efficient energy management for modern homes.
The NULITE R410A DC Inverter Split Air Source Heat Pump features a two-part design consisting of an outdoor heat pump unit and an indoor hydraulic module. This configuration allows flexible installation while keeping key water system components indoors, helping reduce exposure to freezing conditions.
The compact indoor module simplifies system integration and maintenance, providing a practical heating, cooling and domestic hot water solution for modern residential buildings.
Designed for year-round comfort, the NULITE R410A split heat pump combines space heating, cooling and domestic hot water in one efficient system. It supports underfloor heating, radiators, fan coil units and compatible hot water storage tanks.
This multifunctional solution helps homeowners reduce the need for separate heating and cooling equipment, simplify system management and enjoy comfortable indoor temperatures with reliable hot water throughout the year.
Equipped with a Mitsubishi twin-rotary DC inverter compressor and brushless DC fan motor, the heat pump automatically adjusts its operating output according to actual heating and cooling demand.
Unlike conventional fixed-speed systems, inverter technology reduces unnecessary start-stop cycles and helps maintain stable water temperatures with improved energy efficiency. This intelligent operation supports lower electricity consumption, quieter performance and consistent comfort under varying load conditions.
The NULITE R410A split inverter heat pump is designed to operate in outdoor temperatures ranging from -25°C to 43°C, providing dependable heating and cooling performance across different climate conditions.
Combined with advanced inverter technology and intelligent system control, the unit adjusts its operation to changing outdoor temperatures and building demands. This helps maintain stable indoor comfort and reliable hot water supply during cold winters and warm summers.
The indoor hydraulic module incorporates a high-efficiency SWEP plate heat exchanger and expansion tank to support reliable heat transfer and stable system operation. Selected models also feature a built-in inverter circulation pump and 3kW auxiliary electric heater.
These integrated components help simplify hydraulic system design, reduce external equipment requirements and make installation and maintenance more convenient. The practical configuration provides flexibility for different residential heating, cooling and hot water applications.
The NULITE R410A split heat pump features an intelligent microcomputer control system with a user-friendly touch controller for convenient temperature adjustment, operating mode selection and system monitoring.
With support for multiple operating modes, including heating, cooling and domestic hot water, the system allows users to manage year-round comfort more easily. Flexible control and connection options also help installers integrate the heat pump into different residential heating and cooling systems.
This heat pump adopts PV DC direct-drive technology. DC power from the photovoltaic array drives the compressor directly, removing the need for inverters and batteries to maximize solar energy use. It delivers up to 90% energy savings on sunny days and roughly 60% overall energy savings. Switching between grid and PV power is seamless. The system gives priority to PV power, with utility power automatically covering any PV shortfall.
The unit comes with Modbus RTU protocol for seamless integration into building automation and energy management systems. Real-time monitoring covers key operating data such as water temperatures, compressor status, operating mode, fault codes, and energy consumption, while remote control includes on/off, mode switching, temperature setpoints, and special functions such as quiet mode and legionella disinfection. Several heat pumps can be centrally managed through multi-unit networking.Clients can integrate heat pumps into their own control systems for remote monitoring and control.
