Perhaps posted before and the method known by the 'old hands', but for those who haven't done it before , .... how to descale your Truma water heater..

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 Ed 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”.
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..

I don't know.
Obviously the previous owner of mine hadn't bothered as there were deposits of cal around the spouts and quite a lot in the fresh water tank.
The tank was like new afterwards, the heater must have benefited but of course can't be seen.
Judging by the amount that gets deposited in the kettle at home I'll check after 12 months and decide from there.

Travelling around and filling up with water in different places/countries will have an affect on this as we'd not necessarily know how hard/soft the water is in any given place.

That's true, there can be a great variation in levels. Certainly here I accept that it will be present and in higher levels.
I don't know about the other methods, but the citric acid is a mild disinfectant as well. I have heard of white vinegar being used but I was concerned in case it left a taste of it's presence.

I saw that.
I don't suppose they'd recommend it if there was any problem, but I preferred the idea of citric acid. Having said that, I use vinegar regularly to descale the kettle without issue!
Each to their own.
