In Baden-Württemberg, the heating system of a single-family house with approximately 180 m² of living space was completely renovated. An oil condensing boiler with 20 kW, a solid fuel boiler with 15 kW and a solar system with a surface of approx. 18 m² were effectively combined. The basis for this was a correspondingly large hot water tank in which the heat from the various energy sources can be stored with little loss. In addition, the stinking battery tank system was replaced by a space-saving, absolutely odor-proof and double-walled oil tank with a usable volume of around 4,000 liters.
Haase provided the solution for the containers: the principle of on-site assembly made it easy to bring the individual parts into the building. With an outer diameter of 1.70 m and a height of 1.95 m, the T 415-28 hot wter tank offers a volume of approx. 2,750 liters. This high capacity as well as the low heat loss of the storage ensure that the heat introduced, regardless of the source, can be stored and removed again over a longer period of time.
