    FAQs

    What do I need to get an HRV home ventilation system?

    If your home has an accessible roof cavity, then it should be suitable for HRV home ventilation. Your HRV expert will confirm suitability during your free home assessment visit. Get help to find your ideal HRV system

    Can an HRV be used as an air conditioner?

    An HRV system cannot be used as an air conditioner. HRV home ventilation and air conditioning are two different things. Ventilation brings fresh, filtered air into your home, while an air conditioner heats or cools it. We often recommend installing both and can advise you on the best combination. See our home air conditioning range here

    Can an HRV system cool a house?

    An HRV system fitted with a Summer Kit can take advantage of drawing in cooler air from outside if desirable. A typical example during summer, is when the roof cavity air has been heated during the day and remains warmer than the outside air during the evening and early hours of the night.  This is when you can take advantage of venting in the cooler outside air, supporting a better night’s sleep. The Summer Kit is an optional extra with HRV Classic home ventilation that draws cooler air from under the eaves on the south (shaded) side of your house and delivers it to rooms on the sunny (warmer) side of your house.

    Is an HRV system the same as a heat pump?

    An HRV system is not the same as a heat pump. A heat pump uses energy in the ambient air to heat or cool your home and doesn’t bring fresh air in from outside. HRV home ventilation brings a constant flow of fresh, drier, filtered air into your home, which a heat pump can then heat or cool. See our heat pump range

    Do I need a dehumidifier if I have an HRV?

    One of the key benefits of HRV home ventilation is reducing moisture and dampness in your home. Unlike a dehumidifier, it does this for every room in your home.

    Is an HRV system an air purifier?

    All HRV home ventilation systems feature advanced filtration to purify the air your family breathes before it enters your home.

    How is positive ventilation different from balanced ventilation?

    A positive pressure system brings fresh, filtered air from your roof space and uses it to drive out stale, damp air through gaps in your doors and windows.   A balanced pressure system in comparison, pulls stale and moisture-laden air out of the home through outlets in your roof soffit, while simultaneously drawing in fresh air from outside or from the roof cavity if the temperature is more desirable.  A heat exchanger is also included, capturing heat from outgoing air and using it to warm the fresh incoming air

    What size of HRV do I need?

    Every HRV installation is customised to suit the home it's going into. Your HRV expert will spell out the size and cost of your home ventilation system during your free home assessment visit.

    HRV versus heat pumps

    HRV versus heat pumps

    Why not both! HRV home ventilation, whether you choose a positive pressure or balanced pressure system, replaces the damp, stale air in your home with fresh, drier, filtered air. While some systems and some optional accessories help you manage the temperature in your home, HRV home ventilation isn’t a heating system.

    That’s where heat pumps come in. HRV home ventilation works well alongside heat pumps, and we often install both at the same time. And because drier air is quicker and easier to heat, your heat pumps will operate even more efficiently.
