Heizungsersatz.ch
Tap a star to rate
The portal heizungsersatz.ch is aimed at people who want to replace their old heating system and aren't sure whether to choose a heat pump, pellets, district heating, or a hybrid setup. The site explains the pros and cons of each system, gives pointers on costs and subsidies, and helps structure the decision.
Particularly useful is the step-by-step guide, which walks owners from choosing a system through gathering quotes to final acceptance. Several cantonal energy funding bodies link to the site as well, which underlines its neutrality. A request tool lets visitors gather quotes from installers.
