André Suter GmbH

At the center of the offering sits the heat pump water heater, which warms domestic hot water using a heat pump designed specifically for that purpose. The unit draws the energy it needs from the room air in the basement, and the waste heat from an existing oil heating system is especially well suited for this. With the right sizing, the basement barely cools down, and drying laundry there still works. Anyone with a solar power system can also run the water heater on their own solar electricity.

André Suter compares its efficiency to that of a thermal solar system, but puts the cost at roughly a third of it. When replacing an old electric water heater, the company points to a subsidy of 450 francs. Besides the water heater, the business from Beinwil am See in the canton of Aargau also covers plumbing and heating, and supports coordinating other trades during a heating system replacement.
