R290 industrial heat pumps

Industrial R290 monoblock heat pumps

The R290 refrigerant-based industrial air-to-water heat pump is an energy-efficient heating solution for production and warehouse facilities, commercial and office buildings, apartment buildings, and other facilities with high heat demand. Weston Climate’s selection includes monoblock heat pumps with a capacity of [e.g., 50–100 kW], including 380 V three-phase models.

Why choose an R290 heat pump?

• Natural refrigerant. R290, or propane, has a very low climate impact (GWP 3) and is not a fluorinated greenhouse gas. Therefore, it is not affected by the phase-down associated with the EU F-gas regulation. It is a solid choice also in the long term.
• Compatible with any heating system. Our R290 heat pumps heat water up to 75 °C. Therefore, they work with both low-temperature floor heating and fan coil units as well as radiator heating requiring a higher temperature, and are also well-suited to replace a gas, oil, or pellet boiler.
• Reliable even in cold weather. The devices are designed to operate even at low outdoor temperatures. The exact operating limits can be found in the technical data of each product.
• Compact monoblock solution. The entire refrigerant circuit is located in a factory-sealed outdoor unit, and only the water piping enters the building. Refrigerant piping work is not required, and the refrigerant remains outside the building.
• Scalable system. For higher power requirements, multiple units can be connected in cascade.

Where is an industrial R290 heat pump suitable?

• for production and warehouse buildings;
• for commercial and office buildings;
• for apartment buildings and apartment associations;
• for agricultural buildings;
• for the modernization of existing boiler houses.

How to choose a heat pump with the right capacity?

The appropriate capacity depends on the heated area of the building, heat loss, the type of heating system (underfloor heating or radiators), the required supply temperature, and domestic hot water demand. An undersized unit will not cover the heating demand in cold weather, while an oversized unit will operate inefficiently and is more expensive.

We recommend performing a capacity calculation before purchase. Send us the building data. via the inquiry form and we will help you choose a suitable solution.

Installation and accessories

In addition to the heat pump, an industrial heating system typically includes:

• accumulation tank – stores heat and ensures steady operation of the heat pump;
• expansion tank – compensates for the thermal expansion of water and maintains stable pressure in the system;
• circulation pumps – circulate the heat transfer fluid between the heat pump and the heating system;
• heat distribution system – radiators, underfloor heating, or fan coil units.

We also offer installation, so that you can get the whole solution from one place.

Frequently Asked Questions

What is R290 refrigerant?

R290 or propane is a natural refrigerant with a very low global warming potential. It has good thermodynamic properties, which is why it is increasingly used in new generation heat pumps.

Is the R290 heat pump safe?

Yes, if the device is installed according to the manufacturer's instructions. Propane is a flammable gas, but in a monoblock heat pump, the refrigerant is located in a factory-sealed circuit in the outdoor unit and does not reach the building. During installation, the manufacturer's safety distances must be observed.

Is the R290 heat pump suitable for a building with radiator heating?

Generally yes. R290 allows for a higher supply temperature, which is why it is also suitable for buildings with radiator heating. Suitability should always be double-checked during the capacity calculation.

Can a heat pump replace a gas or oil boiler?

Yes, an industrial air-to-water heat pump is a common solution for replacing old boiler rooms. The heat pump can also be used together with the existing boiler, which then serves as a peak load or backup source.
