It provides leaving water temperature of up to 75°C, maintains 100% heating capacity at -7°C,1) and operates heating down to -25°C, providing a warm and comfortable environment even in extremely cold conditions.

Max. Leaving water temp Up to 75℃ Max. Leaving water temp. 75℃ at ambient temp -25℃

ErP Energy label A+++ / A++ High efficiency up to SCOP 4.75 (7kW)

100% Heating capacity At -7℃ Performance at Low Ambient Temp. @LWT 35℃ (5/7/9kW model only)

1) This is only applicable to the 5/7/9 kW models.

All-in-one system enabling simpified installation

LG R290 Monobloc S is a full monobloc system in which all essential hydronic components and the control box are fully integrated into the outdoor unit. As no separate indoor unit is required, it enables efficient space utilization and easy installation, even in homes with limited indoor space, while providing a warm and comfortable indoor environment. In addition, since no refrigerant piping is needed, installation can be completed quickly and easily in many regions without requiring a certified refrigerant technician, reducing both installation time and complexity.2)
2) It may vary depending on the country and installation conditions.

Compact size and reduced weight

With reduced weight and a more compact footprint, the R290 Monobloc S offers improved installation and maintenance convenience. The unit weighs 102kg, with volumes reduced to 0.41 m³ 3) respectively. It also features two support feet instead of three, enabling more efficient installation.4)
3) The weight and volume specifications provided are for the AWHP R290 Monobloc 5–9 kW Single Phase models (HM051HFS, HM071HFS, and HM091HFS), and may vary depending on the model.
4) The unit is up to 33% lighter and 41% more compact than previous models. Specifications are based on the R290 Monobloc S 5–9 kW models and may vary depending on the product.

FAQs

Ε:
How do Air to Water Heat Pumps work?
Α:
Air to Water Heat Pumps operate by transferring heat from renewable energy sources—primarily outdoor air—and converting it into usable heat through a refrigerant cycle. Approximately 75%5) of the energy used for space heating and domestic hot water comes from ambient air, making air-to-water heat pumps an efficient and sustainable solution. The system works through the following five-step process

1. Outside Air

Heat energy is absorbed from the surrounding outdoor air.

2. Evaporator

A low-temperature liquid refrigerant absorbs heat from the air and evaporates into a gas.

3. Compressor

The vaporized refrigerant is compressed, increasing its temperature and pressure using electrical energy.

4. Condenser

The high-temperature refrigerant transfers its heat to water through a heat exchanger.

5. Expansion Valve

The refrigerant pressure is reduced, returning it to its original state, so the cycle can repeat. This continuous process efficiently delivers heating and hot water, even in cold outdoor conditions.

5) Each ratio is general to help understanding, and it is based on SCOP of THERMA V Monobloc S under Low Temperature & Average Climate conditions which is higher than 4. The actual efficiency may vary with water and outside temperatures.

Ε:
What are the advantages of the Monobloc type compared to other system types?
Α:
The Monobloc is an all-in-one air to water heat pump with fully integrated hydronic components packaged within the outdoor unit. This integrated design allows for easy installation in relatively limited spaces while maximizing overall space efficiency.

Because the system does not require any refrigerant piping, it minimizes the risk of refrigerant leakage. As a result, installation can often be carried out quickly and easily without refrigerant-certified technicians.6)

Additionally, the R290 Monobloc S utilizes R290 refrigerant, which has a low Global Warming Potential (GWP) of only 0.02. R290 is also effective in high-temperature domestic hot water production and maintains performance in low outdoor temperature conditions, delivering powerful and reliable heating performance even in low ambient conditions.

6) It may vary depending on the country and installation conditions.
Ε:
Does it support cooling as well as heating and domestic hot water?
Α:
Yes, cooling is also available. In particular, the R290 Monobloc S delivers improved cooling performance compared to the R290 Premium Monobloc. Depending on the model, cooling capacity is increased by 8–46%, and EER is improved by up to 9.6%. The R290 Monobloc S provides reliable heating and enhanced cooling performance to create an optimal and comfortable indoor environment.
Ε:
Does it offer smart control features such as app control and Wi-Fi function?
Α:
Yes. The unit has an embedded Wi-Fi modem, enabling wireless control via the remote controller as well as control through the LG ThinQ app. Maintenance support is also available through BECON Cloud.

The remote controller features a larger 4.3-inch display and full-touch operation, making control more convenient and intuitive. In addition to the controller, the ThinQ app allows you to adjust temperature, schedule ON/OFF operation, monitor energy usage, and manage various operating functions.

With BECON Cloud, remote commissioning and remote firmware updates are possible without an on-site visit, enabling faster and more convenient support.
Ε:
Does it operate quietly?
Α:
The LG R290 Monobloc S is designed with various noise-reduction technologies to provide quiet operation. As a result, its sound power level is 53–59 dB(A) depending on the model.

Noise is further reduced through a new biomimetic fan design. The suction side features grooved patterns, tubercles, and variable winglets, while the pressure side incorporates a waved trailing edge and a leading-edge bulb to help minimize noise.

Thanks to these technologies, the R290 Monobloc S can operate more quietly than the R32 Monobloc S.
Ε:
What is SG Ready?
Α:
SG Ready (Smart Grid Ready) is a function that enables heat pump systems to interact with the external power grid through signal communication. By receiving external signals, the system can automatically adjust its operating mode to optimize energy usage. This helps improve energy efficiency and potentially reduce energy costs. SG Ready certification is granted when a product meets the relevant regulations and requirements set by an authorized certification institution. The LG R290 Monobloc S is SG Ready certified, enabling efficient and cost-effective operation.
