EVOAQ -New Zealand's best ventilation

Building a minor dwelling, a new home, a duplex, or an apartment building?

EVOAQ home ventilation should be at the heart of your design.

Modern New Zealand homes are tightly wrapped for energy efficiency. This makes them easier to heat but harder to keep healthy.

Indoor air quality is how we measure the health of the air you breathe inside. Carbon dioxide, tiny particles, smells, and gases can affect the health of your family and your home.

EVOAQ ventilation is New Zealand's best ventilation systems. Smart sensors and super energy efficient fans control condensation, for a warm, dry, healthy home.

Love the air you breathe for generations to come.

Demand Controlled Ventilation means your building gets the right amount of air at the right time.

Demand Ventilation

Smart software and built-in sensors set EVOAQ apart from older ventilation systems. Easier to control for the best air quality.

Smart software & Sensors

Heat Pump Injection connects your fresh air directly into your ducted heat pump ducting. Constant ventilation even when your heat pump is off without extra diffusers on your ceiling.

Heat Transfer

Transfer heat from your fireplace to warm your bedrooms. Fast and efficient, an EVOAQ heat transfer system helps create a warm and comfy home. for the rest of your home.

Prevent problems caused by cold and damp air, improve your indoor air quality, and enhance your healthy warm new home.

The System

Excess heat is efficiently moved through your home by using the latest fans and automatic sensing controls.

Heat is transferred without affecting the comfortable temperature in your lounge. The best possible air mixing in every room is possible because of the EVOAQ custom-made EC fan & smaller diffusers.

Heat Pump Injection

Connect your ventilation into your ducted heat pump.

Why have more diffusers in your ceiling than you need?

Ducted heat pumps are great for keeping your home at the right temperature. But where is your fresh filtered air coming from? Most ducted heat pumps don't provide ventilation.

Use the EVOAQ heat pump inject kit to add fresh air without extra diffusers in your ceiling.

Injecting air directly into the heat pump ducting provides air even when the heat pump is not off.

Your ventilation and heat pump can finally work together without competing.

Fresh dry filtered air without extra diffusers littering the ceiling.

EVOAQ - FAQs

  • Unovent and DVS systems are low-flow systems, which cost little to run.
    However, when the supply air quality is bad these systems are programmed to switch off. the EVOAQ systems operate in the same low-flow mode, but only when the supply air is too cold or hot. Our advantage is that our systems also do higher airflows when the air is within the optimal range of 18-25°C to further improve the IAQ. Find replacement fans for all of these systems here

  • EC fans are Electronically Commutated fans, which means they use a brushless DC motor. Basic DC motors rely on carbon brushes and a commutation ring to switch the current direction as the motor turns, while EC motors use permanent magnets on the rotor and stationary coils that are electronically powered to control the rotor movement. Using this "brushless commutation" means that these motors have a longer life as they undergo less wear during use, and they are more efficient and waste less power through the electronic motor controls. They are also very controllable with a speed range of 0-100%, as opposed to AC fans that often only have up to 3 speeds available.

  • HRV and SmartVent use high-flow systems which only ventilate when the supply air quality is good. They use fans with a high energy demand which are noisy and expensive to run. When the supply air quality is less than ideal, the systems are turned off as they would otherwise affect the thermal comfort inside the home. Our advantage is that our systems can similarly use high airflows when the supply air quality is good, but they are also able to do very low airflows when the air quality is less good, which helps to maintain the IAQ without affecting the thermal comfort or noise level within the house.

  • VOC stands for Volatile Organic Compounds. It refers to organic chemicals that have a very low boiling point and are usually a gas at room temperature. This includes substances such as formaldehyde (caused by paint vapors) and car exhaust fumes. Most odors in your home are also caused by VOCs. Not all VOCs are harmful to your health, but many can be. While they may not appear to have any immediate effects on your health, they can become very harmful to your long-term health if you are exposed to them over a long time. This is why it is important to continuously extract VOCs from your home. Our VOC extraction fans can detect many of the more harmful VOCs within your home, including formaldehyde, benzene, carbon monoxide, ammonia, and cigarette smoke.

  • IAQ stands for Indoor Air Quality. The IAQ in a building is a measure of several factors, including temperature, humidity, and levels of harmful substances such as pollen, CO₂, and other VOCs. The better the IAQ is inside your house, the better it is for your health.

  • Yes, our systems run 24/7 at an average minimum airflow of 10L/s per room. This meets the standard of ASHRAE 62.2 - based on “Build tight, ventilate right”. Rather than turning off, our fans continue to run at a “trickle” rate, consuming as little as 3W while still maintaining the IAQ. As such, there is little difference in power usage of the system between running on trickle speed and turning the fan off. As an example, the average running cost of a currently installed ventilation system in Auckland is about $0.13 per day, or less than $50 a year.
