Different energy sources and technologies can ensure heat production. The choice depends on several factors, such as the type of building, heating needs, budget and energy efficiency objectives.
GOOD TO KNOW: According to the Swiss Federal Office of Energy, "the heat sector currently accounts for some 50% of energy consumption in Switzerland and causes more than 35% of CO2 emissions". The objective of the Heat Strategy 2050 is to achieve net zero emissions by 2050 by covering all of Switzerland's heat needs with renewable energies and without CO2 emissions of fossil origin.
The ideal heating system must be efficient, economical and environmentally friendly. There is a wide variety of heating systems on the market, each with its advantages and disadvantages.
Here is an overview of the main solutions:
The production of domestic hot water (DHW) represents a significant part of a household's energy consumption. Optimising DHW production is therefore essential to reduce energy bills. Among the most common solutions are electric water heaters, thermodynamic water heaters and combined solar thermal systems.
Central heating is a system that distributes heat to all rooms in a building via a network of radiators or underfloor heating, allowing uniform distribution.
Heat pumps use renewable energy sources. Different types exist: air-to-water, water-to-water, ground-to-water.
Solar thermal is ideal for producing domestic hot water. The panels capture the sun's energy.
The heat network distributes residual heat from a plant to a group of buildings, particularly suitable for urban areas.
District heating makes use of the heat produced by plants and distributes the heat via pipes.
Comparing installation and operating costs varies according to several factors: building size, insulation, needs, region, etc.
