Based on an average-sized home of 150m2 that uses a unit of power at 25 cents:
- DVS EC fan costs about $17 per year to run using an average of 9.5 watts
- Typical AC home ventilation fan costs approx. $140, using an average of 77 watts
- DVS customers SAVE approximately $123 per year per fan*:
$615 savings over five years
$1,230 savings over 10 years
*Based on independent power consumption tests undertaken by Spectrum Laboratories Ltd. Yearly power consumption calculations are based on typical DVS time of use factors.
Annual filter changes are needed to make sure your system operates efficiently and safely. A standard DVS filter costs $62 and is easy to change yourself (see Filter Fitting Instructions).
Other ventilation companies offer filters that could cost $250 and often there is no DIY option.
Depending on the house design, one DVS fan will ventilate a home of 300m2. Other home ventilation systems will only ventilate a home of 100 to 180m2 with one fan.
Compared to a two-fan competitor, a DVS fan can SAVE you up to $188 per year in maintenance costs. That’s $940 savings over 5 years and $1,880 savings over 10 years.
