Ground to Air Heat Exchanger – Harvest the energy below us especially In a hot, humid climates

0 Comment

New innovative solution for precooling the fresh air stream of the HRV ventilation system and  really make the most of your natural surroundings to SAVE YOU ENERGY & MONEY on your airconditiong bill.

ground to air heat exchanger significantly reduces your heating and cooling bills as well as providing long-term environmental benefits.

It does this by exploiting the natural temperature of the ground to provide a cost effective source of renewable energy. At a depth of 1.5 to 2m, the earth’s temperature is a constant 8-12˚C throughout the year.

By drawing air through an underground network of pipes, it is either pre-heated by the ground in winter or pre-cooled in summer. In combination with our VHR unit this significantly reduces the heating and cooling costs of a building.  The underground connecting  pipe is made of polypropylene and comes complete with a unique integrated antimicrobial layer, made of silver particles. This prevents microbial growth on the inside of the pipe, which would otherwise cause musty smells. The air inlet also has a dust and pollen filter, further benefiting allergy sufferers.

There is no mixing of air streams. During winter, the system is able to capture over 90% of the energy from the outgoing stale air before delivering it as warm filtered, preconditioned air into the living areas of the property through the ducting.
