Frequently Asked Questions
Q1. Can I install the BWT Pearl HPB Heat Pump myself?
No. All heat pump installations must be performed by a certified pool technician, and models that require hardwiring must be installed by a licensed electrician. Self-installation may void the product warranty.

This depends on your pool’s volume, location, and heating expectations. Refer to the model comparison table above for recommended pool sizes. If you're unsure, reach out and our team will assist you with sizing.

Yes. BWT Pearl HPB Heat Pumps are designed to operate in a wide temperature range (down to -3°C) and are ideal for both seasonal and year-round pool heating.
Q4. How noisy are the BWT Pearl HPB Heat Pumps?
These models are engineered for quiet operation, with sound levels ranging from 23–39 dBA depending on the model. This makes them one of the quieter options available in their class.
Q5. Do these heat pumps work with saltwater pools?
Yes. BWT heat pumps are compatible with both freshwater and saltwater pool systems. Their internal components are built to resist corrosion in saltwater environments.
Q6. Does the heat pump come with a plug or is it hardwired?
The HPB9 model uses a 10A or 15A plug depending on region and installer configuration. All larger models (HPB12, HPB14, HPB20) require hardwiring by a qualified electrician as part of the installation process.
