The sun warms up our atmosphere and the outer layer of the earth’s crust. In one year the energy sent to the earth by the sun is 50 times higher than the total consumption of energy on our planet. This makes the sun a vast and a sustainable source of energy.

On sunny days you can feel the thermal energy from the sun on your skin. But actually, there is always lots of thermal energy in the air, even on cold winter days or even at night. Heat pumps take thermal energy from the atmosphere, or from the water (rivers, lakes,...) or from the ground. With Altherma, energy is extracted from the outside air which is cheaper and easier than the other alternatives.

Altherma is a highly flexible, energy efficient home heating system that extracts the heat from the outside air, raises this heat to a higher temperature and then distributes warmth around the home through high quality heating units. At the heart of the system lies an air to water heat pump.
Altherma satisfies all your heating and domestic hot water requirements right through the year even on the coldest days. Solar heating panels can be connected to the Altherma system as an option if required. With a fully integrated control system, Altherma will provide consistent comfort with optimum efficiency…and for those long hot summer days Altherma even comes with a cooling option.
