500 Liters Hygiene Buffer Storage with a Heat Exchanger Drinking Water Tank

The hygiene storage tank is responsible for hot water and buffering heating water and solar. Inside the storage there is a stainless steel spiral with an area of 5.70 m². With this high exchanger surface, the hot water for showering is still 40 degrees, with a buffer temperature of 42 degrees in the buffer tank. The stainless steel spiral runs from bottom to top. This ensures that the layering of the hygiene storage is maintained. This is a problem with many other hygienic storage tanks, as the cold water is often introduced at the top, thereby destroying the stratification in the buffer storage tank.
