Heat pump – for a sustainable energy future
Heat pumps are the most economical and environmentally friendly solution for domestic comfort. They use the freely renewable energy source of air, earth or groundwater to heat your home in winter and, with some appliances, to cool it in summer. With a Swiss heat pump of CTA you say ‘goodbye’ to fossil fuels and ‘hello’ to an economical and environmentally friendly alternative.

Investing in a heat pump
The investment costs of a heat pump are higher compared to fossil-fuelled heating systems, but the maintenance and energy costs are significantly lower. This is why a heat pump also pays off financially in the medium and long term.
How a heat pump works
In principle, a heat pump works like a refrigerator. However, while a refrigerator extracts heat from its interior and releases it outside, a heat pump extracts heat from its surroundings and releases it into the living space. All it needs is energy of the air, earth or water and a small amount of electricity to drive it.
How much electricity a heat pump needs
Heat pumps get up to 80% of their energy free of charge from the environment. This means from the air, earth or water. The remaining approximately 20% comes from the power socket. Thus, heat pumps do require electricity, but they obtain the majority of their heating energy requirements from renewable energy sources.
Photovoltaics and heat pumps
Heat pumps and photovoltaic systems are a powerful team when combined correctly. The increasing use of PV systems and heat pumps offers homeowners the opportunity to organise their energy supply sustainably and cost-effectively.
Free Cooling
Free Cooling makes it possible to cool your home naturally by two to four degrees Celsius in summer. The heat pump is not in operation, so the function is practically energy and cost neutral. Free Cooling works with geothermal probe heat pumps and groundwater heat pumps.
Decision criteria
Every house is different. Which heat pump is the right one for your own single-family home or multi-family home depends on various aspects. Different requirements and needs and the particular surroundings make several solutions possible.
