GROUND AS HEAT SOURCE
Ground source heat pumps use heat absorbed by the ground to provide buildings with an environmentally sound and efficient heat supply
GEOTHERMAL ENERGY – DIRECT EXPANSION
The ground acts as a free and plentiful heat store, making it an ideal heat source.Horizontal collectors work day and night, continuously harvesting what is, in essence, stored solar energy. When sized correctly, sufficient source energy will be available even in deepest winter.
Direct ground heat systems (also referred to as direct evaporation), will enable you to achieve the lowest possible operating costs of all currently known geothermal collector systems. You will utilise about 4/5th free energy from the environment. The heat transfer medium in the heat pump circuit is free of chlorine and is ozone-neutral. It picks up geothermal energy directly via the seamless duplex pipes of the horizontal collector (copper, PE protective sleeve). This is achieved by the direct evaporation of the refrigerant inside the horizontal collector. Design/engineering information
