Living in the Highlands we don't get calcium build up in our water system. However whilst we were travelling through europe last year we noticed thee kettle was getting deposits in it.
Our van was bought second hand and came from southern/midlands area. So my point is how do we know what the Truma boiler is like if you live or use your vans in these areas ? Does it get get fouled up with these deposits ? Do you clean it with something ?

Use citric acid about every other year seems to do the trick. We live in a hard water area but don't usually fill up the water here as we usually only tour abroad.

Be careful with citric acid if you have a Webasto heater. It can leave you with a very big bill for a new heater as the acid can corrode the aluminium water vessel.
That said, I have a Webasto and I use citric acid to descale it but I only leave it in for an hour and flush it out very, very thoroughly. :)

We were at Alde having our heating serviced the other day and were warned about using acid products to clean the system.
The acid can react badly with the stainless steel boiler and ruin it.
Their recommendation is to use Puriclean Which will clean the water system.
I don’t know how effective it is at shifting lime scale though.

They also warned us about filling with desalinated water in Spain and Portugal.
The salty water can damage the boiler.
