Rooms that get more sun or have a heat source are generally warmer than those without. With a heat transfer system however, you can ensure other rooms in your home are as warm and cosy as your sunlit lounge.
Heat transfer systems balance the temperature in your home by evenly distributing energy from a heat source, such as a fireplace or heater, throughout your home.
DVS Heat Transfer Kits
While you may have a perfectly good heating source in the living area (such as a wood burner), the heat it generates does not always extend to other areas, such as the bedrooms. The DVS EC Standalone Heat Transfer System uses excess heat from your existing heating to create supplementary heating for other rooms in your home – making the best use of heat you’ve already paid for.
Why DVS?
DVS home ventilation systems are the most advanced ventilation systems in the Australian market. Some of the many benefits include:
- Made in New Zealand.
- German made EC motors by ebm-papst.
- Temperature sensors in the fan and the control panel.
- Custom moulded DVS diffusers that are both attractive and designed specifically for ventilation.
- 5 years warranty.

AC Motors vs EC Motors
AC motors are cheaper than EC motors but still provide excellent performance. They are very quiet during operation and move large volumes of air through ducting. They operate at one fixed speed where they are most efficient.
In real world use, EC motors provide even higher air flow, are extremely quiet during operation, are capable of silent operation at reduced fan speeds, have smoother fan rotation, and consume almost no power at reduced fan speeds. EC motors have adjustable speed and are very efficient at all speeds.
EC Motor Centrifugal Fans

- Extremely low noise during operation
- Can be silent at reduced fan speeds during operation
- R3G220 motor manufactured by ebm-papst in Germany
- Custom New Zealand made fan housing
- 5 year warranty
- IP 54 protection rating.
Standard Insulated Duct vs Green Insulated Duct
High quality insulated duct is essential for minimising heat loss if you want your heat transfer system to work well. Despite this, almost all heat transfer systems use poor quality and poorly insulated duct, which leads many people to believe that heat transfer systems do not work.
Fresh Ventilation conducted the following experiment in the Southern Highlands. The incoming air from the heat source was 32°C, the air in the roof space where duct was located was 5°C, and the transfer length was 18 metres. The air temperature was then measured at the destination. The air exiting from uninsulated duct was 16°C, a loss of 16°C. The air exiting from Rm0.6 standard insulated duct was 21°C, a loss of 11°C. The air exiting from Rm1.5 green insulated duct was 31°C, a loss of only 1°C.
