Descaling
If you use mineral water you will need to descale your hot water tank.
Heated mineral water will cause minerals to fall out. Eventually they will plug up your water-
ways, resulting in a gradual slowdown of the flow rate, leaking faucets, and other problems.
Descaling Solutions
Cooking vinegar is proven to remove calcium deposits efficiently.
Depending on the frequency of decalcification treatments, please use the following propor-
tions of White Vinegar.
- For descaling once every 3 months, use 2 cups (500 ml) of white vinegar with 2.5 liters of
hot water.
- For descaling once every 6 months, use a mixture of 6 cups of white vinegar with 2 liters of
hot water.
- For descaling once every year, use 12 cups of white vinegar and 1 liter of hot water.
- For descaling less frequently than once a year, use undiluted white vinegar.
