The balanced flue system is the engineering behind most DRU balanced flue gas fires. DRU technicians from the Netherlands devised the system in the 1930s. It has since become the industry standard for high efficiency and performance. Many appliance manufacturers have copied the balanced flue system, but none have been able to rival the superior standards that differentiate DRU balanced flue gas fires.
So what is the balanced flue system and how does it benefit your home or workplace?
Comfortable and efficient
Ordinary gas fires have an open-fronted fireplace that is installed into a conventional chimney aperture. The oxygen that the fire burns in order to create its flames is extracted from inside the living room and waste gases are expelled back up the chimney.
So while this type of fire may be easy on the eye, it may not be so kind to your respiration or your fuel bills! It requires constant ventilation to keep it burning. And because of this it consumes more energy and fuel than you can comfortably afford.
In contrast, DRU balanced flue gas fires are room-sealed with a glass window. They have a double-thickness 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.
So there is no loss of comfort and greatly reduced gas consumption. And because the fire is not open at the front, there is no danger of fire hazard or injury.
No chimney – no problem
DRU balanced flue fires can be installed with or without a conventional chimney.
If you home has no chimney, the balanced flue fire can be installed on an outside wall, with the flue going through the wall or up to the roof. With a standard balanced flue model, it is possible for the flue to be 4 metres long horizontally or 10 metres high vertically. With the new DRU PowerVent® system the distances can be even greater, and the fire can be installed in the centre of the room if you wish. 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 benefits of a balanced flue fire, but inserted conveniently into your traditional chimney, this can be done! You will simply need a special flue liner installed in your chimney, using the chimney shaft to replicate the balanced flue effect. In the case of some models, and subject to a chimney inspection, even the flue liner is not required
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.
DRU balanced flue fires come in a huge selection of models, due to the exceptional flexibility of the balanced flue system. Because you are not restricted to the standard chimney opening, you can choose from widescreen letterbox models, 2 sided corner models, 3 sided panoramic models, see-through tunnel models, freestanding stove-style models and even fires that hang from the ceiling.
