## LG Therma V R290 3-Phase Monobloc Heat Pump 14kW


The LG Therma V R290 (LG-HM143HFD.UB41) is a 3-phase monobloc heat pump with a 14 kW heating capacity for large residential and light-commercial applications. 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 400V outdoor unit provides a strong solution for villas and commercial buildings. The system runs on the natural refrigerant propane (R290) with an ultra-low GWP of 0.02 and supplies flow temperatures up to 75°C. Thanks to the 3-phase connection, power draw is distributed evenly across the grid. Because the complete refrigerant circuit is contained within the outdoor unit, you install the unit purely hydronically without an F-gas certificate.


***Please note: selecting a control option is mandatory for installing the monobloc outdoor unit (Control box LG-PHCS0, Hydrobox or Combi unit).***


### Benefits of the LG Therma V R290 Monobloc 14kW 3-phase for installers


- **No F-gas certificate required**: the sealed refrigerant circuit is completely located in the outdoor unit, meaning only a water-side connection is needed
- **Balanced 3-phase power distribution**: prevents phase imbalance in the distribution board on a 3x25A grid connection
- **Strong performance in cold conditions**: delivers up to 89% of maximum heating capacity during cold winter days at -7°C
- **Flow temperature up to 75°C**: easily provides high water temperatures for effective heating while retaining existing radiators
- **Operation on natural R290 refrigerant**: eco-friendly refrigerant with an extremely low GWP of 0.02 for future-proof installations
- **Quiet operation**: silent running at 35 dB(A) at a distance of 5 metres and 57 dB(A) sound power level in quiet mode
- **Fast servicing via side panel**: direct access to the control PCB and terminal blocks without removing the front panel
- **High seasonal efficiency**: achieves energy label A+++ at 35°C and A++ at 55°C with a SCOP up to 4.80

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


### Simple water-side installation and easy maintenance


The monobloc design saves valuable installation time on site. As the refrigerant circuit is sealed at the factory, you perform no refrigerant pipework during setup. The connection requires 1-inch male threaded pipes for heating flow and return and a 400V power cable. For maintenance and commissioning, you reach electrical components directly via the side panel. This removes the need to dismantle the front panel, simplifying servicing.


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


Thanks to the thermodynamic properties of propane, the system delivers solid heating performance during heavy frosts. The heat pump supplies heating water up to 75°C and maintains strong capacities down to -7°C. This allows you to replace a conventional boiler directly with a fully electric setup without altering existing radiators or building pipework. Furthermore, the natural refrigerant easily satisfies strict environmental standards for years to come.
