Hoval Grundwasser-Wärmepumpen
Tap a star to rate
Hoval is a Liechtenstein manufacturer with a distribution network across Switzerland. Its groundwater lineup includes units from 5 kilowatts up to well over 100, covering everything from single-family homes to multi-family buildings and commercial properties.
The seasonal performance factor of groundwater heat pumps in Switzerland typically sits between 4 and 6, because groundwater stays at a constant 10 to 12 degrees year round. That makes it more favorable than air to water systems, which become less efficient in cold weather. Hoval recommends a hydrological survey of the site before every project.
