Descaling
If you use mineral water you will need to descale your hot water tank.
When mineral water is used, calcium deposits will block passageways in the hot water tank.
This blockage can be observed by the gradual slow down in the flow rate.
Descaling Solutions
There are 2 substances proven to remove calcium deposits efficiently. They are:
1. White vinegar used for cooking.
2. Lemon acid in powdered form, used by beverage makers and bakeries.
Depending on the frequency of decalcification treatments, please use the following proportions
of substances.
1. 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.
2. Lemon Acid:
- For descaling once every 3 months, use a mixture of 1 oz. of powdered lemon acid and 3.5
liters of hot water.
- For descaling once every 6 months, use a mixture of 2 oz. of powdered lemon acid and 3.5
liters of hot water.
- For descaling once every year, use a mixture of 4 oz. of powdered lemon acid and 3.5 liters
hot water.
- For descaling less frequently than once a year, use a mixture of 5 oz. of powdered lemon acid
and 3.5 liters hot water.
