Ahrens Schornsteintechnik enlighten with a free advice hotline. Around 42 percent of the total energy consumption of in Austria go on the account of the housing/building area (source: igpassivhaus.at) the rising number of passive and low energy houses which efficiently counteracts. Modern low-energy houses have a measure of energy under 30 kWh/m2a, passive houses under 10 kWh/m2a. Current alternative? Yes, with additional stove and chimney system for ambient air-independent operation. It’s now even particularly cold and there seems little sun, as well as in the winter, then it does, that the calculated heating load is not sufficient and needs to be heated. Often, this happens through a heat pump that is heated with electricity. However, this has safety risks E.g.
power failure in itself. An efficient alternative is to purchase an additional oven. However, each combustion required oxygen, where there may be no connection between the stove and space in airtight houses but. Therefore there are specially tested and approved fireplaces on the market AMBIENT air independent operation. They are connected exhaust-side to the flue and air-side to supply leadership, not compromising the independent circuit of controlled housing ventilation. The Ahrens LAF will be routed the combustion air from the outside of the chimney head and the annular gap to the Firebox (tile, fireplace, pellet stove).
The chimney head is trained it so that no fumes with the fresh airflow can mix. The supply management necessary for the additional heater about the system exhaust system can be realized the easiest, cheapest and safest. Having a room-air dependent fireplace, would you suck the air from the room, smoke could be drawn due to the negative pressure in the room (due to controlled housing ventilation) from the stove in the room. This would mean mortal danger”, as the gew. Managing Director Bmst. ing. Edmund Drohojowski. Ahrens explains whether chimney sweep, homeowners or builders eventually deals everyone who builds a passive house, with the theme of energy supply. Even if it is relatively low in buildings in low energy construction. Often encounter questions concerning operation of an extra fireplace. To remedy the Ahrens of now all interested has provided an educational video to the LAF: this video arrives on the functioning of the LAF Ahrens. The Ahrens LAF is the only fireplace system with concentric air/exhaust duct and W3G approval, as well as additional suitability for pressure operation (P1). This is possible due to the unique isostatic Ceramic tube with 6 cm sleeve. Constantly requests by passive homeowners reach us, how they can best the needs rest heat in their building. This is a technically complex issue with which we are concerned for decades. Provide this information publicly available, to make the function of an ambient air-independent chimney more transparent. And I think, well we succeeded with the product video for the LAF Ahrens”, so Managing Director Mathias Ahrens.
