Solvarmebeholderen.dk supplies mantle tanks for small domestic solar-powered water heating systems.

Since the early 1990s, mantle tanks used in combination with low flow* operation in the solar collector loop have been shown to provide better thermal performance than traditional spiral tanks used in combination with high flow operation in the solar collector loop. 

Solvarmebeholderen.dk manufactures mantle tanks to take full advantage of this documented superior performance. Our aim is to make mantle tanks the standard choice for small solar-powered heating systems.

Solvarmebeholderen.dk’s heat storage tanks are available in two sizes: 165 l and 300 l. They are manufactured in high-quality stainless steel, using the latest know-how.

The thermal performance of a solar heating system with a mantle tank is approx. 20% larger than the thermal performance of a similar solar heating system using a spiral tank.

The increased thermal performance of a mantle tank is the result of very good thermal stratification with high temperatures in the top of the tank and low temperatures in the bottom of the tank, which results in:

Lower auxiliary energy consumption, because the hot water is already present in the top of the tank.

Longer operation time of the pump in the solar collector loop during the day and throughout the year, because of the low temperatures in the bottom of the tank.


Other advantages:

  • Less lime deposit
  • Smaller and cheaper pipes
  • Lower pumping power

Thanks to the higher temperatures at the top of the storage tank, less water has to be tapped. This results in reduced lime deposit and a cheaper solar circuit as a consequence of the low flow* operation, which requires smaller pipes and lower pumping power.


Solvarmebeholderen.dk

– supplies optimised stainless steel mantle tanks. The tanks are designed for small solar domestic water systems, and are available in two sizes: 165 l and 300 l.

Solvarmebeholderen.dk is owned by Martin Dandanell, who has worked with solar heating since 1984.
