Why Do We Need Home Ventilation?

Mould, Moisture and Dampness

Mould is almost always caused by dampness and poor ventilation in your home.

The signs of dampness and poor ventilation can often be quite obvious.

However, in newer homes, which are built to be almost airtight under building regulations, signs of poor ventilation aren’t always initially visible and may exist in the form of excessive moisture that can’t escape and hidden damp, which accumulates over time.

When damp and mould are allowed to grow, they can be a trigger for asthma attacks, cause flu, fatigue and even more severe respiratory illnesses.

Toxic mould syndrome occurs worldwide and is linked to headaches, nausea, nose bleeds, depression, eczema, lack of energy, respiratory problems and hay fever (allergic rhinitis). Asthma sufferers are particularly at risk in damp and mouldy homes, as are babies, children, the elderly and people with weakened immune systems.

Window Condensation

Condensation forms on cold surfaces when they come into contact with moisture in the air.

Dripping condensation and excessive moisture can result in a number of issues for your home and your family’s health:

  • Left uncontrolled, window condensation can cause mould and mildew that damages curtains, clothing and bedding.
  • Cold and damp homes exacerbate asthma and are more likely to contain mould spores.
  • Mould spores are dangerous to you and your family’s health and are an equally dangerous trigger of asthma.
  • Wooden window frames can warp and become difficult to operate.
  • In severe cases, condensation also causes paint to peel.

Purify Indoor Air

Australian homeowners are increasingly keeping their windows closed due to noise, pollution and security. This reduces healthy natural ventilation and can increase the inhalation of harmful pollutants and respirable dust.

Modern homes are well insulated and sealed tight to increase energy efficiency, but are more likely to have poor ventilation because they cannot breathe. Opening doors and windows is not always practical and does not provide adequate ventilation, which needs movement and exchange of air.

Off-gassing of paints, floor coverings and building materials creates an unhealthy environment indoors. In fact, the air inside our home is 4 times more polluted than the air outside our home, meaning that 50% of toxic substances we are exposed to will come from inside our homes.

Pollutants in our homes range from carbon dioxide (from breathing), carbon monoxide (from cooking and unflued gas heaters), Volatile Organic Compounds (VOCs) and formaldehyde (from building materials), mould, pollen and dust mites.

Asthma, Allergens and Hay Fever

Two million Australians suffer from asthma.

Asthma Triggers:

  • Allergens are triggers of asthma.
  • Cold and damp homes exacerbate asthma and are more likely to contain mould spores.
  • Mould spores are dangerous to you and your family’s health and are an equally dangerous trigger of asthma.
  • Dust mite excreta is one of the most common asthma triggers. Dust mites are microscopic tick like arachnids typically found in damp environments. Dead dust mites and dust mite excreta can make up 10% of a 2 year old pillow’s weight.

An allergen is something that triggers an allergic response. Allergens found in everyday environments include pollen, mould, animals and dust.

The rate of environmental allergies, including hay fever, eczema and dust mites, has doubled in 15 years. Most of the research points to the state of our damp, cold home environments and the air we’re subsequently breathing in.

Symptoms and Reactions to Allergies:

  • Hay fever (allergic rhinitis).
  • Eczema.
  • Hives.
  • Asthma.

About DVS

For more than two decades DVS have been making homes healthier and more comfortable to live in.

Home ventilation systems manufactured by DVS use advanced technology (such as EC motors and Wi-Fi connectivity) to gently introduce cleaner, drier, filtered air from the roof space or from outside your home. Home ventilation systems significantly reduce problems like crying windows, mould and mildew, which are key triggers for asthma and allergies.

In winter, good air circulation and home heating are essential for maintaining air quality. A home ventilation system from DVS removes the excess damp, moisture-filled air and improves the overall air quality inside the house, making it much healthier for you and your family. And, once it’s installed, a DVS ventilation system costs from just eight cents a day to run, making it a good investment for not only the well-being of your family but also the value of your home.

We are proud to offer the latest range of premium DVS products, including positive pressure heat recovery home ventilation systems (HRV), balanced pressure energy recovery home ventilation systems (ERV), summertime cooling addons, integrated heat transfer addons, and a range of advanced filtration technologies.

New Zealand Designed and Manufactured – Internet Connected Home Ventilation Systems

DVS EC Connect systems can be connected to your home Wi-Fi router. This means when they make improvements to the system software we are able to send them to you without the need for a potentially costly service visit.

The combined technology, connect-ability, and features available from the DVS EC Connect range of home ventilation system cannot be compared.

Humidity Sensing and Control

The humidity sensitive control function constantly monitors humidity levels inside your home and in the air supply. Automatically adjusting to ensure that only air which will keep your house healthier and drier is introduced.

Carbon Dioxide CO2 Sensing and Control

Closed windows trap air filled with contaminants and carbon dioxide that cause discomfort, fatigue, and lack of focus and can make your in-home climate unhealthy.

The DVS EC Connect range constantly monitors carbon dioxide levels. When the carbon dioxide reaches an unhealthy level, the system automatically increases the level of fresh air being introduced into your home. This minimises any risk brought on by having too much carbon dioxide in your air, and is also great for getting a good and refreshing night’s sleep.

The CO2 sensors are a remote wireless device and can be positioned in up to four places in your home.

Temperature Sensing and Control

The temperature sensing function allows the DVS EC Premium Connect positive pressure home ventilation system to react to differences in air temperature (comparing the air supply to the air inside of the home). Adjusting the air supply automatically to make the best use of free warmth when it is available and then slowing to a minimum ventilation rate when the air is cooler. You are able to adjust the aggressiveness of the system according to what you want to achieve with your DVS.

Custom Logic

Custom logic is intelligence that you create yourself and add in to the programming of the ventilation system. You would typically add your own custom logic where the functionality required cannot be obtained with the normal operation of the ventilation system.

External sensors can be installed in various locations where data is needed (such as outside or near a fireplace). Custom logic can compare data from all of the sensors in the system:

  • Keypad: internal temperature sensor, external temperature sensor, internal absolute humidity sensor, set temperature.
  • Main Fan: internal temperature sensor, external temperature sensors 1-4, internal absolute humidity sensor, external absolute humidity sensors 1-4, fan speed sensor.
  • Slave Fan: internal temperature sensor, external temperature sensor.
  • Auxiliary Fan: internal temperature sensor, external temperature sensor.
  • PIR Sensor: motion high, motion low.
  • Custom Switch 1: on, off.
  • Custom Switch 2: on, off.

When certain conditions are met custom logic can be activated for a period of time or for the duration the conditions are met. Custom logic allows near endless customisation of a DVS ventilation system:

  • 240V Relay: on, off.
  • Summer Ventilation Damper: on, off.
  • Heat Transfer Damper: on, off.
  • Spare Damper 1: on, off.
  • Spare Damper 2: on, off.
  • Main Fan: off, low, med, high, max.
  • Slave Fan: off, low, med, high, max.
  • Auxiliary Fan: off, low, med, high, max.

Custom logic can be used to control external appliances through custom integration.

Custom Integration

Custom integration allows a DVS ventilation system to be integrated with other components in the home. The main fan includes ports to control two additional 24V dampers and up to 2200 watts from a 240V socket.

DVS Positive Pressure Heat Recovery Ventilation Systems

DVS EC Premium Connect
Fresh, dry, filtered air from your roof space or from outside your home delivered to the habitable areas of your home. A positive pressure is created inside your home that ‘pushes out’ the stale, unhealthy air.

The DVS EC Premium Connect is a superior positive pressure ventilation system. Featuring the latest ventilation technology from DVS, you can now control your home’s humidity, temperature and air quality from a fingertip. Enjoy the benefits of a drier and healthier home now with our EC Premium Connect model.

The DVS EC Premium Connect is an enhanced positive pressure ventilation system and is designed to keep your home dry and healthy with minimal user input.

The ventilation system features a wireless CO2 sensor, which continually monitors the level of carbon dioxide in your home. When CO2 reaches an unhealthy level, the ventilation system will instantly increase the level of fresh air delivered into your home – helping to keep you and your family healthier all year round.

Thanks to its heat retention and heat recovery functionalities this ventilation system adapts to the ambient temperature. If the supplied air temperature is warmer than your home, free warmth will be transferred into your living areas up to your desired temperature. If the supply air is colder than your house (such as winter evenings), the fan speed can be slowed down to keep the home as close as possible to your desired temperature.

The humidity sensing function monitors humidity in the supply air and inside your home, ensuring your home will only be ventilated with air that helps make it healthier and drier.

DVS EC Premium Connect Diagram

How Does it Work?

A quality German-made energy-efficient EC fan quietly takes the drier, fresher air from your roof space or from outside your home and draws it through a high efficiency air filter, tested to international standards. The fresher, filtered air is then gently pushed into your home through the DVS patented ceiling diffusers. The incoming air is directed along the ceilings where it mixes with warmer air and spreads evenly through the home. Put simply, it creates a positive pressure inside your home that ‘pushes out’ the stale, unhealthy air.

Optional Addons

  • Automatic Summer Ventilation: A continuous supply of fresh, filtered air is drawn from outside of the roof space when the roof space itself becomes too hot. This allows you to make better use of your DVS EC Premium Connect home ventilation system during summer, ventilating with fresh air when you’re not home to open the windows.
  • Integrated Heat Transfer: This is designed to provide supplementary heating to rooms isolated from the main heating source (log burner or other solid fuel burner). The DVS EC Premium Connect ventilates your home with fresh, filtered air, and switches to a heat transfer system when required to help warm the cooler rooms in your home.
  • Sub Floor Ventilation: The DVS EC Premium Connect ventilates your home with fresh, filtered air, while simultaneously controlling sub floor ventilation fans to ventilate your sub floor area underneath your home.

DVS Controller

The controller offers personal control of your home environment, all through an easy, simple to use interface. Your system will be configured for you, and the airflow and settings individually calibrated to the size of your home to run automatically. However, you are able to easily adjust the system functions or fine tune the fan speed to better suit your needs or use the Fan Boost option for clearing the house of extra moisture or smells.

The EC Connect controllers are Wi-Fi capable and can be connected to your home internet. This allows you to download any software updates DVS make available when they are improving their systems.

DVS Balanced Pressure Heat Recovery Ventilation Systems

DVS EC Reclaim Connect
Fresh, dry, filtered, prewarmed air from outside your home delivered to the habitable areas of your home. Warm, stale air extracted from kitchens and bathrooms. Heat is recovered by a European counterflow heat exchanger.

Build tight, ventilate right!

The DVS EC Reclaim Connect is a superior balanced pressure ventilation system. With the increase in design of airtight dwellings in Australia there is a greater focus on balanced ventilation and heat recovery. Have an existing air conditioner? Installing a home ventilation system from DVS can boost its performance by making your home’s air easier to heat and cool!

If you’re looking for ways to create a healthier and more energy-efficient home, our ultimate balanced pressure heat recovery ventilation system is the perfect ventilation solution for your home. The heat exchanger reclaims energy produced by the exhausted stale air, and redistributes it into your home. This means that less heating is required to keep your home warm, which equates to big savings – both to your power bill and the environment.

Controlled ventilation is the key to achieve necessary air changes while maintaining an energy-efficient building. The DVS EC Reclaim Connect is an enhanced balanced pressure heat recovery ventilation system, and is located in your roof space. The two energy-efficient EC fans will effortlessly and quietly extract the damp, stale air and deliver fresh, filtered air into your home to keep it dry and healthy. As the ventilation system extracts the stale air, the heat exchanger reclaims energy that passes through it, which means that less energy escapes from your home.

Mechanical ventilation is essential to manage internal moisture in airtight buildings. For this reason balanced pressure heat recovery ventilation systems like the DVS EC Reclaim Connect are perfect for modern homes.

The DVS EC Reclaim Connect is our ultimate whole-house balanced pressure heat recovery ventilation system, and features a wireless CO2 sensor, which continually monitors the level of carbon dioxide in your home. When CO2 reaches an unhealthy level, the ventilation system will instantly increase the level of fresh air delivered into your home – helping to keep you and your family healthier all year round.

The humidity sensing control function ensures your ventilation system will only ventilate your home with air that will assist in keeping your home drier, while the energy the heat exchanger has recovered will be re-used in your home. That means less heating is required to keep your home at a desired temperature. That equates to big savings on your power bill and also benefits the environment.

DVS EC Reclaim Connect Diagram

How Does it Work?

The DVS EC Reclaim Connect is located in your roof space (or a cupboard in your home) and uses two German-made energy-efficient EC fans ⑥. One fan will effortlessly and quietly extract the damp, stale air out of your home ①. As the DVS extracts the stale air, the heat exchanger reclaims energy from it (usually generated by activities such as cooking, showering and paid for heating) before exhausting it outside.

The second fan draws a constant supply of filtered, fresh, outdoor air into your home ③. The energy recovered by the heat exchanger is transferred to this incoming fresh air, warming or cooling it before it is delivered to your home ②. The state-of-the-art European counterflow heat exchanger will operate at up to 98% efficiency without mixing the stale and fresh airstreams ④.

Because the recovered energy is re-used in the home, less heating is required to keep your home at the desired temperature when ventilating your home. That equates to big savings – both to your power bill and the environment.

When warm air is available in the roof space, the DVS EC Reclaim Connect (when fitted with an optional Solar Gain Roof Intake) can use this free heat by passing it through the heat exchanger without roof space air being supplied to the home ⑤. This is achieved by opening the roof space bypass to allow the roof space air to mix with the extracted exhaust air from your home and pass through the heat exchanger helping to pre-warm the incoming fresh air.

To increase the effectiveness of your system during summer, an Automatic Summer Bypass can be fitted to allow the incoming fresh air to bypass the heat exchanger when the outside air is cooler than your home.

DVS EC Reclaim Connect state-of-the-art Recair Sensitive heat exchanger

DVS Filters are Better for the Environment

Made Using New Zealand Wool

Scientifically developed by Lanaco, in New Zealand, using wool grown in New Zealand to create advanced filtration systems that enable you to enjoy healthier, safer air.

Lanaco’s Helix technology is so trustworthy it has been selected by NASA to protect astronauts in their next voyage to the moon. So, the same technology used in critical life support systems in space is found in the latest generation of DVS filters.

The Best of New Zealand Innovation

DVS’ new standard filter with Helix technology uses natural wool fibres, the world’s most positively charged fibre, to act as a magnet and capture those minute dust particles and airborne contaminants.

In fact, the new Helix wool filter is more than 99% efficient at 2.5 microns.

Its superior performance won’t affect the airflow of your system, keeping your fan working at the most efficient, and cost effective speed.

The chart attached shows comparison with other filter technologies illustrating how hard a fan needs to work for the desired result.

The DVS Standard Wool Filter with Helix technology delivers world class-leading performance with a lower environmental footprint.

Caring for the Environment

DVS created their latest filter using Helix technology with their customers and planet in mind, leading with science and sustainability.

Their new filter technology is made using biodegradable wool fibres making it more environmentally sustainable and better for our planet.

DVS have always offered their filters as an easy DIY option for customers wanting to change their own filter, which is why they have utilised a filter pocket design.

Progressing to Helix filtration has allowed DVS to retain a filter pocket design whilst at the same time increasing filtration efficiency: a win-win for our customers and our planet.

Benefits of Helix Filter Technology

  • Class-leading particle capture performance: Harmful particles are captured via the exceptional electrostatic capabilities of Helix MERV15 filters. This same technology has been scientifically developed for industrial, medical and respiratory health sectors.
  • Extremely breathable and super easy air flow: The Helix filter matrix offers superb breathability and much lower air flow resistance supporting a lower energy usage whilst still ensuring high particle removal.
  • Bacteria resistant: Wool fibres within Helix filters naturally resist and reduce the growth of bacteria and microbes on the fibre surface.
  • Natural way to reduce toxins: Natural wool fibres within Helix filters have an affinity for toxic vapours, safely and permanently eliminating them from the air.
  • Safer against fire: Natural wool fibres within Helix filters increase the flame retardancy, ensuring a safer filter in a compromised environment.
  • Eco-friendly and sustainable: Helix filters all contain naturally biodegradable wool fibres making it more environmentally sustainable and better for our planet.
