New building: Age-appropriate wooden house

March-Holzhausen

The Müller family built a new house in 2018 – wheelchair-accessible for old age. They opted for the HALLER overall concept consisting of infrared heaters, photovoltaics and hot water boilers and produce more electricity than they consume!

Statement

from the customer

"We built a wheelchair-accessible house for old age in 2018. We heat our wooden house with 9 HALLER infrared heaters and a Scandinavian wood stove. It's an absolutely ingenious system. The photovoltaic system produces more electricity than the whole house needs. The heat from the infrared heaters is very pleasant, and they're easy to use."
