The myclimate subsidy programme supports the replacement of old oil or natural gas heating with fully automated pellet heating. Property owners can receive funding for building heating from the programme at locations in Switzerland where there is currently no financial support from the federal, cantonal or local government.
In Switzerland, oil and gas heating systems for room heating and warm water, which are in need of modernising, are generally replaced by other heating systems that run on fossil fuels. From a climate protection perspective, replacing the old heating system with automated pellet heating or another non-fossil technology would be a better choice. This subsidy programme aims to reduce the high investment costs needed for pellet heating. The climate protection programme was developed with the support of proPellets.ch and Holzenergie Schweiz and can be implemented thanks to the financial contributions of the KliK Foundation. The amount of the subsidy is calculated by myclimate on the basis of the previous yearly energy consumption and corresponds to 18 centimes per kilowatt hour. This corresponds to approcimately CHF 360 per kWth (nominal heat output), if the pellet heating system is properly dimensioned. The conversion from fossil-fuel driven to renewable heat production using wood reduces the amount of greenhouse gas emissions generated by heating.
Pellet heating systems are fully automated wood heating systems. During the production of pellets, dried sawdust and wood shavings from the manufacturing industry are compressed into cylindrical rods. Two kilograms of pellets contain about the same energy as a litre of heating oil or a cubic metre of natural gas. The pellets are delivered by tanker and kept in the buildings storage, which is often located in the former oil tank room. From there the fuel is automatically transported into the combustion chamber by means of a conveyor or suction system. The burning provides warmth for room heating and the production of warm water, and leaves behind a small amount of ash. The incorporation of a buffer tank allows for needs-based control of heat distribution to users.
The subsidy programme is open to private households, businesses and industry (no process heating), provided that the admission criteria in the registration form are met. Only fully automated central heating systems up to 70 kWFL (thermal input) with a seal of quality from Holzenergie Schweiz, which are not eligible for state financial support, will be subsidised. You can find out in which cantons state funding is available on the Energiefranken website. Please see the registration form for details of the application process:
