    The AirSense™ range

    For the latest in home ventilation technology, including our most powerful fan, even more effective filter and WiFi-connected app control, HRV AirSense™ delivers. The AirSense™ range includes a balanced pressure option, managing air outflow as well as inflow – ideal if you have a modern home with tightly fitted doors and windows.

    Essential Essential HRV AirSense™ Essential is our latest home ventilation system, efficiently delivering dry, filtered air to your living areas as well as real-time visibility of your indoor air quality. Essential+ Essential+ The HRV AirSense™ Essential+ model adds a Summer Kit. This very clever accessory helps manage indoor temperatures in summer, by drawing cooler air from under the eaves on the southern (shaded) side of your house and delivering it to rooms that face the sun. Balanced Balanced HRV AirSense™ Balanced pressure system only draws fresh air from outside, incorporating a roof cavity bypass. This is an ideal system for homes where the outside temperature is colder than the inside temperature for prolonged periods of time, or any home when you want to maximise ventilation while minimising heat loss. Balanced+ Balanced+ HRV AirSense™ Balanced+ removes stale and moisture-laden air from your home, while simultaneously drawing in fresh air from outside or from the roof cavity if the temperature is more desirable with solar gain. Incorporates a heat exchanger, so warm outgoing air is passed over incoming filtered air, recovering up to 90% heat energy and helping manage the cost of running your heat pumps or other heating sources.

    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.

    Installing your HRV AirSense™ home ventilation system

    Once we've measured and assessed your home, your custom-made system will be ready to install in a few weeks' time. Because of its larger central fan housing, HRV AirSense™ might not suit installation in homes where roof access is limited, but we'll check this before making a recommendation. Your HRV expert will keep you updated on progress and arrange a time for installation. This usually takes just one day, but could be longer for large homes or more complex systems.

    On the day, your installers will talk to you about where your control panel and ceiling vents will go, then once installation is complete, they'll show you how to set and operate your system.
