This R290 heating heat pump application in Germany shows how four 12kW air-to-water heat pumps were used to support space heating for an 826m² building. The system has a total nominal heating capacity of 36kW, giving an approximate capacity-to-area ratio of 58W/m².

This figure provides a useful reference for similar heating projects. However, final heat pump selection should still consider building insulation, heating terminal type, required supply water temperature, local outdoor design temperature, and system control strategy.

The project required a heating solution for an 826m² building in Germany. For a building of this size, heating capacity is only one part of the system design. The solution also needs to support stable operation, flexible load matching, and practical service planning.
Germany is a demanding market for heating applications. Buildings often require reliable space heating over a long heating season. At the same time, many customers are paying closer attention to refrigerant direction, long-term product compliance, and system efficiency.
For this project, a multi-unit R290 heat pump configuration was selected. Instead of using one large heating unit, the system uses three 12kW heat pumps. This makes the heating system more flexible under different load conditions.
*12kW R290 heat pump Germany
The system uses four R290 air-to-water heating heat pumps, each with a nominal heating capacity of 12kW. Together, the four units provide a total nominal capacity of 36kW.
This configuration gives the project several practical advantages.
During milder weather, the building may not require the full 36kW capacity. In that case, part of the system can operate while other units remain on standby. When the heating demand increases, more units can join the operation.
This staged operation helps the system respond to changing heating loads. It also avoids relying completely on one large unit. For maintenance planning, a multi-unit system can be more practical in many project conditions.
For OEM and ODM heat pump customers, this is also a useful product strategy. A 12kW R290 model can work as a standard platform. When multiple units are combined, the same model can support larger heating projects without requiring a completely different product range.
*Application-R290 air to water heat pump for heating
The project uses four 12kW units for an 826m² heating area.
The calculation is simple:
3 × 12kW = 36kW
36kW ÷ 826m² ≈ 0.044kW/m²
Approximate capacity-to-area ratio: 44W/m²
This makes the case useful for reference. It shows how a 36kW R290 heat pump configuration can be applied to a real space heating project in Germany.
However, this should not be treated as a fixed selection rule. Heat pump sizing depends on more than floor area. Building insulation, window area, local climate, heating terminal type, supply water temperature, buffer tank design, and user comfort requirements can all affect the final selection.
For similar projects, the 44W/m² figure should be used as a project reference, not as a universal sizing standard.
*Application - 12kW R290 heat pump Germany
R290 is a natural refrigerant with very low global warming potential. For heating heat pumps in Europe, it is becoming an important refrigerant direction, especially as the market moves away from high-GWP refrigerants.
In this case, R290 was selected because it supports both heating performance and long-term product planning for the European market.
For German heating projects, refrigerant choice is not only a technical detail. It can influence product positioning, installer communication, catalogue content, and future market acceptance.
Since R290 is a non-fluorinated refrigerant, this heating solution avoids the HFC quota pressure faced by many high-GWP refrigerant systems in the European market. For OEM and ODM customers, this makes R290 a stronger option for long-term heating product development.
This case is designed for space heating. It is not a domestic hot water case or a swimming pool heating case.
The system can be used with suitable hydronic heating terminals depending on the final project design. These may include floor heating, fan coils, radiators, or other water-based heating systems. The actual configuration should be confirmed according to the building’s heat loss, required water temperature, and installation conditions.
A three-unit system is suitable for projects that need more heating capacity than a single residential unit can provide, but do not necessarily require a heavy commercial heating solution. This makes the configuration relevant for large homes, villas, small apartment buildings, office spaces, and light commercial heating applications.
The main value of this system is flexibility. The project can use part-load operation during lower demand periods and increase output when outdoor temperatures drop.
For OEM and ODM heat pump buyers, this German case is more than a product display. It shows how a standard 12kW R290 heat pump platform can be used in a real heating application.
This is important for brand owners and distributors. In many European markets, customers are not only asking for product parameters. They also want to see whether the product can be applied in real projects.
An 826m² heating case gives sales teams, distributors, and installers a clearer reference. It helps them explain how several standard units can be combined to support a larger heating demand.
For brands planning to sell R290 heat pumps in Germany or other European markets, this type of case can support product line planning, project-based sales, and installer training.
Three 12kW units provide a total nominal heating capacity of 36kW. The system can operate in stages according to the building’s heating demand.
The case shows how R290 heating heat pumps can be applied to an 826m² building heating project in Germany.
R290 supports the European market’s move toward lower-GWP refrigerants. This gives OEM and ODM customers a stronger long-term product direction.
Compared with relying on one large unit, a multi-unit configuration provides better flexibility for part-load operation and maintenance planning.
A 12kW model can serve as a standard product platform. By combining multiple units, customers can cover larger heating projects while keeping the product line easier to manage.
Before planning a similar heating project, several points should be checked carefully:
Building area and actual heat loss
Building insulation level
Local winter design temperature
Heating terminal type
Required supply water temperature
Buffer tank configuration
Multi-unit control or cascade control requirements
Installation space and maintenance access
Local certification and energy efficiency requirements
Installation manuals and after-sales documents for the target market
These details affect the final system design. A heat pump project should not be selected by floor area alone.
For heat pump products exported to Europe, refrigerant selection should consider both regulatory direction and market acceptance. HFC refrigerants such as R32, R410A, and R134a are subject to different regulatory pressure compared with natural refrigerants.
R290 is a natural hydrocarbon refrigerant. It is not an HFC refrigerant. This gives R290 heat pumps a clear advantage in low-GWP product positioning.
For the German heating market, this matters. A heating product should not only meet today’s project demand. It should also support the customer’s long-term product strategy.

This R290 heating heat pump application in Germany shows how four 12kW R290 air-to-water heat pumps can support space heating for an 826m² building.
With a total nominal heating capacity of 48kW and an approximate capacity-to-area ratio of 58W/m², the project provides a useful reference for similar heating applications. More importantly, it shows the value of a multi-unit heating configuration: flexible operation, easier project replication, and stronger relevance for low-GWP heating product lines.
For OEM and ODM heat pump customers targeting Germany and other European markets, this case offers a practical example of how standard R290 heating units can be applied to real building heating projects.
