Correct Ventilation for a Dry and Healthy Home

New Zealand modern buildings and homes are now, rightly, well insulated and airtight, due to improved building materials, standards and building methods.
Controlling air movement is critical in achieving a dry, healthy, energy efficient, comfortable environment and protecting your internal furnishing integrity.

Method and Benefits

MHRV delivers outside filtered fresh air into your building without creating uncomfortable drafts and mitigates excessive demand on your heating and cooling systems.
The health benefits to the occupants cannot be understated.
Protects your internal building and furnishing investment.
Modern airtight buildings need to ventilate to remove moisture, CO2 and dirty air more than ever before. For those who have investigated ventilation, understand that MHRV is not only the best option to ensure a clean environment, but also in achieving thermal comfort
The incoming air is filtered before it is introduced into the buildings. MHRV has two airflows (supply & exhaust) that pass one another parallel within the heat-recovery heat exchanger without mixing physically. The heat from "stale" extracted outgoing air is transferred to the "fresh" air introduced from outside.
The overall MHRV process exhausts moisture laden air from wet rooms such as bathrooms, kitchen, laundries and supplies fresh air into all habitable living areas and bedrooms. Thereby replacing the need for independent bathroom and laundry extraction fans.

So Why Use Heat Recovery Ventilation Systems?

Introduces 24/7 fresh air without noise pollution and outside dirt & dust.
Ensures safe and healthy indoor air quality - low CO2.
Exhausts wet areas thereby reducing moisture loads.
A dryer home is easier to heat.
Removes cleaning chemical toxins and off-gas/VOC.
Automatic Summer bypass to prevent stuffiness and hot spots.

Allows windows to be closed during inclement weather.
Protecting temperature loss, wind/drafts, safety, insects and pollen etc.
Low energy EC motors provide extremely cost effective operation.
Easy installation & maintenance with fully automated or user-friendly controls.
