The R290 Monobloc DC Inverter Heat Pump is an integrated system that combines the compressor, heat exchanger, and hydraulic components into a single outdoor unit. Unlike split systems, this monobloc heat pump eliminates the need for indoor refrigerant piping and complex installation procedures. For homeowners and installers, it means easier setup, lower labour costs, and minimal indoor disturbance. As a heat pump supplier serving global residential markets, Green Power has designed this home heat pump for convenient retrofit and new build applications alike.
As one of the leading heat pump manufacturers, Green Power utilizes R290 refrigerant — a natural gas with an ultra-low Global Warming Potential (GWP). The r290 heat pump achieves outstanding seasonal efficiency and environmental sustainability. Meanwhile, the DC inverter heat pump adjusts compressor and fan motor speeds according to demand, ensuring smooth operation, lower power consumption, and whisper-quiet performance. This combination of R290 and inverter control gives homeowners an advanced domestic air source heat pump that delivers reliable comfort and significant energy savings year-round.
The R290 Monobloc DC Inverter Heat Pump is engineered for all-season operation. It provides consistent heating and hot water supply even when the outside temperature drops to –25 °C. Capable of producing outlet water temperatures up to 75 °C, this residential air source heat pump is perfectly suited for both modern underfloor systems and older radiator-based heating networks. Whether in mild or cold regions, this home heat pump delivers stable comfort and exceptional energy efficiency that meets Europe’s strict A+++ energy-rating standards.
Green Power has established itself among top heat pump manufacturers and suppliers worldwide, offering ODM and OEM solutions built with premium components — including GMCC compressors, Swep heat exchangers, Wilo pumps, and Danfoss controls. Each r290 heat pump undergoes strict testing to ensure performance, safety, and durability. As a global heat pump supplier, Green Power delivers dependable monobloc heat pump systems tailored for residential and commercial needs, providing long-term reliability and after-sales service for every home and domestic air source application.
Residential Boiler Replacement & Home Heating Upgrade
For homeowners who currently rely on a conventional boiler system, the R290 Monobloc DC Inverter Heat Pump provides an ideal upgrade path. With its monobloc design (no indoor refrigerant lines), installation is simplified and disruption is minimal. Whether your home uses radiators, underfloor heating, or a mix, the unit’s high output water temperature and wide ambient operating range make it a realistic alternative. As a domestic air source heat pump solution from a reputable heat pump supplier, this product supports efficient home heating, hot water generation and lower energy bills—transforming your residence into a high-performance, future-ready home heating system.
New Builds & Cold Climate Applications
In new build construction or regions with colder winter climates, specifying a residential air source heat pump system is increasingly common. This R290 heat pump is engineered for performance even at low ambient temperatures, delivering reliable output and ensuring comfort throughout the season. Developers and specifiers can rely on the heat pump manufacturer’s credentials and global export track record when specifying this home heat pump system. The monobloc installation format further streamlines commissioning and reduces risk on site—making it an excellent choice for modern building projects, multi-unit housing or homes in colder zones.
Hybrid or Phased Conversion Systems
Some properties may not be able to completely remove existing boiler systems or may wish to adopt a phased transition to heat pump technology. In such hybrid scenarios, the R290 Monobloc DC Inverter Heat Pump can function as the primary heating source while the existing boiler remains for peak load or as a backup. Its compatibility with typical hydronic systems, ease of installation and inverter efficiency make it a strong candidate when selecting from heat pump manufacturers and suppliers. Homeowners benefit from a smooth transition, improved energy efficiency now, and a clear path to full heat pump reliance later.
