Free Air Heating & Cooling

It is generally acknowledged that Mechanical Ventilation with Heat Recovery (MVHR) is integral to today’s residential building specification.

MVHR is strongly encouraged by current Building Regulations and is considered essential for low-energy and Passive houses now, MVHR can provide Winter heating & Summer cooling, with the addition of a Ground Energy Intake Duct, which delivers natural heating and cooling energy, with no running costs!

The Ground Energy Intake Duct is laid at a depth of 1.5m, where ground temperatures remain at 7-12o all year round. The air supply to the MVHR Unit can therefore be 7-9o warmer than atmosphere in Winter and 12-14o cooler in Summer, with pollen filtration included. As a result, significant heating & cooling gains are enjoyed, carbon emissions reduced and comfort levels greatly improved.
