Replacing your heating in Unterseen: what you should know
How Unterseen heats today
According to the Register of Buildings and Dwellings, 60.4% of residential buildings in Unterseen heat with oil or gas: 42.0% with oil, 18.4% with gas. The Swiss average is 49.8%.
Replacing an oil heating system also removes the tank and frees up space in the basement.
18.5% of residential buildings in Unterseen already heat with a heat pump, compared with a Swiss average of 26.2%.
61.6% of residential buildings were built before 1980. In older houses we check at the site visit whether the radiators are sufficient and which flow temperature is needed. Then we decide with you between an air-to-water and a ground-source heat pump.
