Ground-air Heat Exchangers

Ground-air heat exchangers (also known as earth tubes) offer an innovative method of heating and cooling a building and are often used on zero carbon / near zero energy home buildings. Ventilation air is simply drawn through underground pipes at 1.5m deep which pre-heats the air in the winter and pre-cools the air in the summer.AWADUKT Thermo pipework was specifically designed for this application with its integrated antimicrobial silver layer.
