Today, our homes and workspaces are extremely well isolated. That is obviously a good thing because you are wasting less energy. But these particular insulation standards must necessarily be accompanied by adequate ventilation – preferably mechanical. A ventilation system extracts the air used from our living environment and supplies it with fresh air. By ventilating with a system integrated heat recovery device, you can count on energy savings of the order of 40%.
Ventilation and heat recovery go hand in hand
There are many ventilation systems that effectively accomplish this important task – the transfer of stale and fresh air. However, there is only one type that combines this task with space heating and thus promotes energy savings.
A heat recovery ventilation system expels used air and provides fresh air, first heating it with the heat of the outside air. This ingenious system ensures a healthy and pleasant environment at all times. While the air is continually refreshed, the temperature remains the same. No need to increase the heat. That's why heat recovery gives you a financial advantage. Our calculations show that you need 40% less energy thanks to such a device.
Ventilating your house used to involve a lot of heat loss, especially in the winter. However, this is a legal obligation, as ventilation ensures a healthy climate at home. Fortunately, there is now a ventilation system with heat recovery, which allows us to keep the heat inside the house and achieve solid energy savings.
Ventilating is better than aerating
In addition to heat savings, ventilation is also much more efficient than aeration. If you open the window for an hour, it will only take three or four hours for the air to return to its pre-aeration condition. On the contrary, ventilation has the enormous advantage of constantly changing the air in your home, 24 hours a day.
Tips for choosing a fan with heat recovery
Make sure you choose a low energy fan. Otherwise, you may win with one hand what you lose with the other.
Also, pay attention to the efficiency of the fan, i.e. the heat rate actually recovered. To do this, look at the NBN en 308 standard: the fan must meet at least 85%.
For optimal fan operation, make sure that the amount of incoming air is the same as the amount of outgoing air. Ask your installer to check the output and input rates of the installation in order to make an appropriate adjustment.
Choose a quiet fan, as the noise causes noise pollution that can become very annoying in the long run.
Finally, make sure you can stop heat recovery in the summer by an automatic by-pass.
You can check these resources in various languages about heat recovery: in Swedish - Värmeåtervinning, Danish - Varmegenvinding and German - Wärmerückgewinnung.
Exodraft offers a complete range of commercial ventilation solutions with heat recovery. This way you can easily and efficiently ventilate your office, store, hotel or other commercial operation while saving on your energy bill. Our range includes both compact units and larger and more powerful ventilation systems.
