Drugasar Explain The Balanced Flue System

The balanced flue system is the technology behind most DRU gas fires and gas wall heaters. DRU engineers from the Netherlands invented the system in the 1930s. It has since become the industry standard for high efficiency and performance. Many companies have copied the original system, but none have been able to match the superior standards that are the hallmark of DRU products.
So what is the balanced flue system and how does it benefit your home or workplace?
Comfortable and efficient
Most conventional gas fires have an open-fronted fireplace that is inset into a standard sized chimney. The air that the fire uses to create its flames is drawn from inside your living room and waste products are expelled up the chimney. (See drawing 1)
So while this kind of fire may be pleasing to the eye, it may not be so kind to your breathing or your bank balance! It requires constant ventilation to keep it burning (ever heard the saying ‘It’s stuffy in here’?). And because of this it consumes more energy and fuel than you can reasonably afford.
In contrast, a balanced flue gas fire is room-sealed using a glass front. It has a sophisticated flue that uses natural convection to draw the air from outside the building for combustion and expels it back to the outside through a separate compartment of the flue. (See drawing 2)
So there is no loss of comfort and minimal fuel consumption. And because the fire is not open at the front it is much safer to use.
No chimney – no problem
DRU balanced flue fires and wall heaters can be installed with or without a conventional chimney.
If there is no chimney in your home, the flue can be fitted through an outside wall or through the roof. It is possible for the flue to be 4 metres long horizontally or 10 metres high vertically. So you have a great deal of flexibility when deciding where to locate your fire.
If, on the other hand, you would like to have all the advantages of balanced flue technology, combined with the aesthetic appeal of a traditional chimney, this can be done! All you will need is a special flue liner installed in your chimney, using the chimney shaft to replicate the balanced flue effect.
A further advantage of this is that your fire can be installed in the classic way, using a fire surround to look like a traditional fireplace. Alternatively it can be mounted further up the chimneybreast as a ‘hole-in-the-wall’ or ‘hanging’ fire.
Either way, you will enjoy the combination of a beautiful fire that uses modern, efficient technology to bring you endless comfort and pleasure.
