Truma water heater switch

[Neil Jenkins]

Hi everyone I'm new to the group so hope I've done this right! I've just changed the van and can't remember what chap said in handover about water heater switches as they are different to my last van. Its a truma unit with two switches on front. One says truma boiler with 50 or 70 which I know is the water temperature, and the other says truma el with two squiggles one bigger than other. Is the first one gas and the one with el electric high or low. Think I switched wrong one on because water is pulsing. Thanks for any help Neil.

If your water is pulsing I would have thought it would be more to do with the pump.Or do you mean it's going hot then cold?

Sorry all got it now top one gas bottom one electric that was why it was pulsing had both switched on by mistake!

According to the manual you can use both gas and electric at the same time, heats up really quickly.
Only the gas is thermostatically controlled though.
What do you mean by pulsing?

I think you should be focussing on the pump pressure. If the pulsing is rapid, see if you can adjust the operating pressure. You can 'play' with the Truma controls as much as you like.
