I.ON Energy Services
I.ON Energy Services is a Swiss company specializing in solar photovoltaic and heat pump installation.
How does a heat pump work?
“A heat pump captures thermal energy from the air, ground or water and concentrates it to heat your home. To produce 100 % of the heat you need, it only consumes 25 to 35 % in electricity; the remaining 65 to 75 % come free from the environment.”

“The seasonal COP (SCOP) varies by type: 3.5 to 4.5 for air-to-water, 4.5 to 5.5 for vertical geothermal. We contractually guarantee the seasonal COP calculated during the study.”

“Budget 32,000 to 48,000 CHF gross for a well-sized air-to-water unit, 55,000 to 80,000 CHF for geothermal. Cantonal grants amount to 4,000 to 9,000 CHF depending on the canton and output. With tax deductions, the effective net cost falls to 21,000–32,000 CHF for a standard air-to-water unit.”
View in the company profileDoes a heat pump really work in winter?
“Yes. Modern air-to-water heat pumps (Daikin Altherma 4 H, Vaillant aroTHERM plus, Stiebel Eltron WPL-A, Panasonic Aquarea T-CAP, Alpha Innotec hybrox, Buderus Logatherm WLW176i) operate down to -20 °C with a reduced COP. Geothermal is never affected by outdoor temperature since it draws from the stable-temperature ground. No electric backup is required for correctly sized installations.”
