The Truma water heater heats water inside a tank. It uses a burner or electric element to warm the water. A thermostat controls the temperature to keep it steady.
Water flows through pipes to your taps or shower. The heater turns off when the water reaches the set temperature. It restarts automatically when more hot water is needed.
Common Issues
