Heat recovery ventilation is the obvious solution to the requirements for ventilation in todayâ€™s energy efficient homes. Building Regulation L (England and Wales) lays down exacting standards of insulation and air tightness designed to minimise space heating needs and carbon emissions.
A pressure test is required to show that the home meets the low level of air leakage required. All of this is easily undone by the conventional use of trickle vents and extract fans for ventilation.
A whole house ventilation system maintains the air tightness of the structure whilst providing continuous balanced ventilation throughout the dwelling. The energy efficient, healthy way to ventilate.
