So What Exactly Is An HRV?
An HRV or Heat Recovery Ventilator is a system that keeps warm air in while pushing stale air out.
Due to today’s house building techniques and renovations being more thermally efficient, the air flow in our homes is lacking which results in fresh air changes only happening when doors and windows are opened. Opening a window can help, but it is not very economical. Thus, the HRV was born.
A typical unit has two fans – one to take out household air and the other to bring in fresh air. What makes an HRV unique is the heat-exchange core. The core transfers the heat from the outgoing air to the incoming air. So while the old stale air is removed, the heat we pay for remains.
Not only does it ensure that the indoor polluted air is regularly being replaced by an equal quantity of fresh clean air, but many allergy sufferers have found relief from symptoms using an HRV as well. The system filters the air coming into the home before dispersing it and can remove many common allergens, such as pollen and dust, in addition to regulating humidity levels preventing mold and mildew issues.
A heat recovery ventilator can make your house a cleaner and healthier living environment; all while helping keep fuel bills down.
