I have recently had one fail on a truma system that was less than 9 months old.
Truma water heater not working.
Most truma hot water systems have a small 10 amp.
Ceramic slow blow fuse fitted on the control pcb.
If you are lacking heat by searching the web i found that there are several problems that seem to afflict these heaters 1 relays not working.
When the appliance is switched on the burner starts automatically as soon as the hot water faucet is opened and the flow of the water is greater than approximately 0 4 gallons per minute 1 5 l min.
Compact heater for many uses.
Truma varioheat heaters varioheat is an especially compact heater for caravans motor homes and vans.
In the truma boiler gas a powerful gas burner heats the water in your caravan or motor home quickly completely without a power supply the gas boiler has excellent insulation to ensure that almost no heat is lost.
If the water temperature drops the electronics reignite automatically.
No i don t fix caravan heaters but to help you here is how i fixed mine.
It can be installed flexibly in various positions vertically or horizontally and is suitable as the main heater in a van or an additional heater in larger vehicles.
The unit has worked without further problems following replacement of the fuse.
My model has settings at 500w 1kw and 2kw.
I was having problems with my heater.
They are known to fail for no apparent reason.
