I have a new to me camper with a truma therme hot water heater, which is tucked away under the side units, I can see a dial type valve with a clear pipe coming from the lower side of unit to the floor, (where it’s goes after is no longer visible but straight down into the floor so I’m guessing this is the drain down valve? It also looks like it may possibly be able to function as an air electric heater but as far as I know it only has an of or on control? Is this a dual purpose unit ?
This is wrong From the start in the first minute as you can't control the room temperature when you just have the water on! This video will confuse you even more ......
