The Truma website it will tell you to de-scale as follows: -
“For hygienic reasons you should decalcify the water container occasionally. Use special decalcification products from camping specialists or conventional vinegar essence or citric acid, for example.
Fill the decalcifying product in the recommended ratio into the appliance via the water system, allow it to work and then rinse the Combi heater thoroughly with fresh water”
Following an email to Truma I received the following reply:
“Please find below instructions for descaling the Truma water heater:
Dilute 2 litres of white wine vinegar into 10/12 litres of fresh water, introduce into your water system via your water inlet, (removing the filter if one is fitted for this process) open the taps to pull through to the heater and then leave the solution in the heater for 4 to 5 hours and then flush through with fresh water”.
I have also been provided with the following additional advice concerning the use of Citric acid:
The ratio Truma recommend is 1 tablespoon of citric acid to 1 litre of water”.
My preference is Citric Acid.
Make up the solution of Citric Acid,
I used an 11lt watering can and poured the solution into the fresh tank, then pumped through all taps, hot and cold, including shower head, and toilet flush.
Drain down and flush system with plenty of fresh water..
This will also descale the water tank level probes
The same method can also be used for cleaning the Thetford toilet cassette
