Webasto Thermo Top-change temperature?

[umpire111]

Is there any way to change the temperature of the heated water. Can’t find any mention of changing this in my manual or on the net?

Don't think so. Heater is either on or off

Was afraid of that

Fit a thermostatic mixer valve to the calorifier. You can then set the temperature of the hot water to the shower and taps at a safe level and it has the added benefit of using less hot water so the hot water in calorifier goes further.

And the other added benefit is that you won't scald yourself with hot water after you've been for a cruise.

 

If you fit a TMV on the hot water outlet pipe from your calorifier then the water temp must be set above 60C to kill Legionalla bacteria. I'd also recommend fitting a Y strainer between the calorifier and the TMV because otherwise the TMV can get bunged up with bits of limescale from the calorifier.

The water temperature within the calorifier will be at engine thermostat temperature, 80 degrees C or so. Only the water delivered to the taps will be at the TMV setting.

 

Good idea about using a Y strainer.

Yes I understand that, but my point was that the water in the pipes to the taps should also be above 60c, at least occasionally to kill off any nasty bacteria.
