Grundfos Solar pumps are specially designed for circulating heat transfer fluid in solar systems for hot water heating and supplementary heating. Their construction withstands the higher operating temperatures typical of solar circuits.
Available in various lengths (130 and 180 mm) and power ranges depending on the size of the solar system and the number of collectors.
Frequently Asked Questions
- Can I use a regular heating pump instead of a solar one? We do not recommend it – solar circuits reach higher temperatures and use a different type of heat transfer fluid, which the Solar pump is specifically adapted for.
- How do I choose the pump output based on the number of collectors? The pipe length and the number/size of solar collectors are decisive – for larger systems we recommend consulting with us.
- Is the pump also suitable for a combined system (solar + boiler)? Yes, the Solar pump is commonly used in combined systems where solar energy supplements boiler heating.
