## LG Therma V R290 1-phase monobloc heat pump 9kW


The LG Therma V R290 (LG-HM091HFD.UA41) is a 1-phase monobloc heat pump with a heating capacity of 9 kW for residential projects. Within our range of **[heat pumps](https://www.estg.eu/en-gb/assortment/heat-cool/heat-pumps)** from **[LG Electronics](https://www.estg.eu/en-gb/brands/lg-electronics)**, this outdoor unit provides an effective solution for larger single-family homes and renovations. The system uses natural propane refrigerant (R290) with a GWP of 0.02 and supplies flow temperatures of 75°C even in freezing temperatures down to -15°C. This allows you to connect the system directly to existing radiators without altering the heat distribution setup. Because the complete refrigerant circuit is housed within the outdoor unit, you install the pump on a purely hydronic basis without an F-gas certificate.


***Please note: selecting a control option is mandatory for the installation of the monobloc outdoor unit ([Control Box LG-PHCS0](https://www.estg.eu/en-gb/p/LG-PHCS0.ENCXLEU), [Hydrobox](https://www.estg.eu/en-gb/p/LG-HN16XAHC.NK1) or [Combi Unit](https://www.estg.eu/en-gb/p/LG-HN20XAHY.NK1)).***


### Advantages of the LG Therma V R290 Monobloc 9kW for the installer


- **No F-gas certificate required**: the sealed refrigerant circuit is completely self-contained in the outdoor unit, requiring only a hydronic connection
- **100% heating capacity at -7°C**: delivers the full 9 kW heating output during freezing conditions without performance loss
- **Flow temperatures up to 75°C**: effortlessly reaches high water temperatures for effective heating while preserving existing radiators
- **Operation on natural R290 refrigerant**: an environmentally friendly refrigerant with an ultra-low GWP of 0.02 for future-ready installations
- **Quiet running performance**: quiet operation with 34 dB(A) at 5 metres distance and 55 dB(A) sound power in low noise mode
- **Fast servicing via the side panel**: direct access to the control PCB and terminal blocks without removing the front grille
- **High seasonal efficiency**: achieves energy label A+++ at 35°C and A++ at 55°C with a SCOP up to 4.70
- **Flexible system integration**: connects seamlessly with the LG Control Box, hydrobox indoor units or an all-in-one combi unit with a 200L cylinder

- **16 kW**: [LG-HM163HFD.UB41](https://www.estg.eu/en-gb/p/LG-HM163HFD.UB41)


### Simple hydronic installation and servicing convenience


The monobloc configuration saves significant assembly time on site. Because the refrigerant circuit is hermetically sealed at the factory, you perform no work on refrigerant piping during installation. Connecting the unit requires only 1-inch male threaded pipework for flow and return alongside the 230V electrical feed. During maintenance or commissioning, you access internal electrical parts directly through the side panel. This eliminates the need to remove the front casing, significantly speeding up routine service.


### High performance with propane (R290) in renovation and new build


Thanks to the thermodynamic qualities of propane, the system delivers reliable space heating even during severe winter weather. The heat pump preserves its full 9 kW capacity down to -7°C and supplies heating water up to 75°C. This allows you to replace a fossil-fuel boiler with an all-electric setup without upgrading existing radiators or interior piping. Moreover, this natural refrigerant protects the environment and comfortably complies with future European legislation for decades to come.
