Breathe easy…

With the HRV Home Ventilation system, outside air is drawn through the roof space (up to 7 air changes per hour) and into the system. A superior deep pleat, electrostatically charged filtration system, and the best fan available, create the heart of New Zealand's leading whole home ventilation system. The incoming fresh air is filtered through the HRV system's medical grade filter and then distributed through your home. Filtered air, free from pollutants, gently circulates through the rooms creating a fresh, healthier home environment with an even temperature that you control.

The key benefits…

• Remove toxins, pollen, allergens and harmful dust
• Remove the environment dust mites thrive in
• A sensitive choice for asthma and allergy sufferers
• Improve air quality in your home = improved health

It's your roof… 
Your free solar energy

The average NZ rooftop collects 220 thousand kWh of solar energy per year - more than 20 to 30 times the home's total energy requirements*. The sun's free energy heats the air circulating in your roof space - yours to harness for heating and dehumidifying.

Your free heating

The HRV system harnesses the free heat captured by the rooftop and circulates the warm air throughout the home. With just a 5°C temperature difference between the roof and the home, HRV provides every room with the equivalent heat of a 1200W heater - all for the cost of running a light bulb.

Your free summer night cooling

As the sun sets and the night air cools, the roof space temperature drops more quickly than inside your home. The HRV system delivers the cooler night air into your home making it more comfortable on hot, sticky, humid nights.

The key benefits…

Energy efficient whole home ventilation Reduce heating bills and GHG emissions Reduce reliance on heaters and air conditioning Improve efficiency of current heating

It's not called the "Land of the
Long White Cloud" for nothing…

A combination of New Zealand's damp climate, and the moisture you create in your home every day from cleaning, 
cooking, and washing is working against you achieving a healthy home. Sort it with HRV Healthy
Home Ventilation.

Fresh air circulating through your roof space is drawn into the HRV system. The roof space air has less humidity than air inside your home. The incoming dry, fresh air is filtered through the HRV system's medical grade filter and then distributed through your home. Positive pressure acts to expel damp and dust laden air and provide a healthy ventilation flow even with the windows closed. Warm filtered air, free from damp and pollutants, gently circulates through the rooms creating a warmer, drier, healthier home environment.

The key benefits…

Remove condensation, damp and harmful mould Create a healthier home for your family Create a home that is easier to heat Remove the environment dust mites thrive in

Harness the sun's FREE energy
to help warm and dry your home…

Sunlight hits the air through solar radiation - the average NZ rooftop collects 220 thousand kWh of solar energy per year* - more than 20 to 30 times the home's total energy requirements. _{EECA, 2002}

Solar radiation warms the air circulating through your roof space and is drawn into the HRV system which is located in the apex of your roof space. The incoming warm fresh air is filtered through the HRV system's medical grade filter and then distributed through your home. The fully functioned HRV controller automatically works towards the desired temperature you set inside your home. Warm filtered air, free from pollutants gently circulates through the rooms creating a warmer, drier, healthier home environment.
