PGB · Buderus Systempartner
Which heat pump really suits your building?
We consider heating load, heat emitters, flow temperature, domestic hot water demand and building condition together. The result is not a standard package, but a system suited to your home and the way it operates.
Current Buderus heat pumps
A range for the right application.
The information provides initial guidance. Output, noise, hydraulics, installation and funding eligibility are checked separately for your project.
Logatherm WLW186i AR
R290 air/water heat pump for single- and two-family houses. A flexible system family for new builds and modernisation.

- Flow temperature up to 75 °C according to the current German information
- R290
- Check the heat source and permit requirements individually
Logatherm WPT156
Domestic hot water heat pump as a stand-alone supplement. It produces domestic hot water and does not replace a heat pump for space heating in the building.
- Wall-mounted sizes 80 / 100 / 120 / 150 l
- Floor-standing 200-/250-l classes
- R290 · PV function
- Check capacity and availability for each version
The output figures describe family or variant values, not the modulation range of an individual unit. For WLW186i/176i, 11,6 kW applies to the E version; other variants reach up to 11,5 kW. The highest SCOP of 4,77 at W35 applies to WLW186i-10 AR E. A product SCOP is not a building's seasonal performance factor(JAZ). For WPT156, 200/250 denotes size classes; the actual cylinder capacity depends on the version.
Apartment buildings & Commercial properties
Logatherm WLW286.2-22: when a single-family house unit is no longer enough.
For apartment buildings, housing providers and suitable commercial projects, the R290 range offers scalable system solutions. PGB focuses on the 22-kW version.
22-kW class
9,5–21,7 kW at A−7/W55.
High flow temperature
70 °C down to −10 °C; 65 °C down to −16 °C outdoor air.
Reversible
Heating and active cooling possible.
Up to 14 units
Cascades based on individual system design.
After commissioning
More than installation. Keep track of operation.
A heat pump must work well in the actual building. PGB therefore combines installation and user instruction with monitoring and operating analysis, insofar as the specific system and agreed scope of service support this.
Anomalies are assessed in the context of the building, heating curve and operating mode. A display alone does not replace professional assessment.
PGB System-Monitoring
Identify deviations. Assess them technically.
1 · Record
Available operating data and system messages.
2 · Assess
Technical assessment by PGB.
3 · Optimise
Targeted adjustments following assessment and agreement.
4 · Support
A point of contact after handover too.
