Not Afraid Of Legionella.

Decentralized water heater protect consumers from dangerous bacteria is water not only for drinking. Every day we use it also to the showers, cooking, washing or rinsing. For this quality of drinking water available is tenants. This must be so, because bacteria in the water can be dangerous. The new more stringent drinking water Ordinance is therefore in November 2011.

Thus for example landlords of apartment buildings have to annually inspect their equipment to the hot water for Legionella. These bacteria, which are inhaled through the finest water droplets, respiratory problems or even severe lung infections can trigger especially when showering. Self used houses the expert review of the hot-water system is absolutely advisable but no obligation, to prevent hazards from the line”, so Roland Grabmair from the initiative heat + in Berlin. Who uses decentralized tankless water heater in the House, is on the safe side. The modern devices that heat Water just as the flow passes through, so that Legionella bacteria have no chance to develop into the cold water pipes.

Legionella is most multiply at temperatures between 30 and 45 C. Excess of 60 C they die quickly and also cold water provides no growth medium for bacteria,”Garcia knows. Hot water systems where the water is stagnant longer periods of growth-enhancing temperatures pose a higher risk. This is the case for example in houses with Central hot water storage tank. Therefore here large amounts of water must on high temperatures above 60 C constantly be heated and stored, to prevent the formation of Legionella. This costs energy and goes into the money. Decentralized devices work much more efficiently. Electronic tankless water heater consume no standby power and adjust the flow rate sparingly. More information on the topic will find under about the initiative heat + for many homeowners in the coming years Investment in a contemporary house heating on. With a comprehensive information and services the initiative heat + in enlighten, as an efficient plant technology can contribute to a more intelligent use of energy in house and apartment. In the focus are innovative solutions such as the heat pump, the decentralized hot water production with electronic instantaneous water heaters, electric underfloor heating and the home ventilation system with heat recovery. The members of the initiative include the companies AEG Haustechnik, Clage, DEVI, Dimplex, Stiebel Eltron and Vaillant, and the Central Association of electrical and electronics industry (ZVEI) and the HEA technical community for efficient use of energy.
