Heat Recovery Ventilators
When creating an energy-efficient, airtight home it’s very important to consider ventilation. Your home needs the exchange of indoor air with outdoor air to reduce indoor pollutants, moisture, and odors. Buildings today are intentionally made increasingly airtight, which results in less ventilation. An ideal solution for tightly sealed homes, an HRV system exchanges stale air from inside with fresher outdoor air. To ensure absolute comfort, the system also captures heat from contaminated air before it is moved outdoors.
An HRV unit is not a heating system, it’s a ventilation system that works independently of a heating system. It recovers heat from warm air inside the home that would ordinarily be lost through natural draught ventilation, wall grilles and trickle vents etc.
Benefits of Heat Recovery Ventilators
- Constant supply of fresh air with higher comfort levels
- Overall air quality within the house is significantly increased which is of benefit to all occupants especially Asthma & Hay Fever sufferers
- No condensation
- No fungal growth in bathrooms
- Fresh smelling bathrooms (air is constantly being changed no need for air freshener)
- Less dust and fewer spiders as they feed on dust mites
- Extra security having all windows closed at all times
- Quieter house, less outside noise as windows are closed
- Lower heating bills. While the unit does use a small amount of electricity, the amount of energy saved greatly out-weighs the amount used.
HRV units should be checked every year. Basic servicing can be carried out by the owner and the main component of maintenance is changing the filters.
