I'm trying out the heating and hot water on my new van. It's a Truma combo. I'm trying it out first on gas. The heating is working fine, but the hot water icon on the panel is flashing. Does that mean it's still heating up? My instruction manual isn't in English. Thanks

Photo of switches would be good as different ones.

Yes, flashing means it is doing that function. Steady icon when the heater is up to temperature or the heating has reached its limit.

I had it on eco, it's stopped flashing, but the water was only luke warm. I ran it for 20 seconds and it started flashing again. Does that sound right?

water heats a bit with heating on, but need to turn water heating on as well to get hot water. Eco is for the fan on the blown air heating, water heating gives a temperature, 40º and 60º i think, blown air has temperature then choice for gas, electric or both and eco or high for fan.
Not needed at the moment but you can put it on fan only for cooler air in the hot weather.

Not correct, on the hot water settings ECO is 40° & HOT is 60°.
When setting the temerature ECO sets the fan to auto.

Yes. Eco is lukewarm and the light started to flash as it was heating the water again.

We have a Truma system on our Auto-Trail and have often wondered what the auto setting is on top of the heater unit. It doesn't fluctuate in output so what's auto about it?

Not on ours eco only comes up for space heating and have a choice of 40 or 60 for water, choice too of electric 1 or 2 gas or both for both space and water heating looking at images, there is more than one inet panel, perhaps theirs is more modern.
Then again I may need to have another look at our system.

ECO is a waste of time, it heats the water to 40° then the thermostat turns off and doesn't turn back on until water temperature is below 27°.

Interesting you should say that, I only ever use mine on eco and it heats enough water for both myself and my wife to have a hot shower.

On the CP Plus panel they changed the logo for water from 40 to ECO as it didn't really keep the water at 40.

Mine has eco, hot and boost.

Boost heats to 62°& disables heating if its on, then turns off.

When it's cold I often set the water on boost and heating on 18°, timer set to come on at 7:15am.
So the boiler fires up at 7:15 with just the water heating as it disables the heating. When the water is up to temperature around 8:00 the heating turns on. So we can get up later to a nice warm van with hot water for showers.
Although with the water heating on boost it has turned off but because the heating is running it keeps the water hot.

"Boost" will take the water temperature up to 70 deg,handy for showering as it then needs more cold to dilute back to a more user friendly temperature, thus reducing the hot water amount taken per shower. From memory, you can only use the "boost " function twice.
This setting is also useful for a boiler clean and de-scale.

If your Truma heating is a C3002 model (or similar) try auto with the fan speed setting at 5 , I think it should adjust speed of the fan according to the temp.

The 'A' on top of the heater unit. It's the type that looks like a conventional domestic heater. The fan just blows at constant speed and doesn't fluctuate at all. It doesn't bother us at all but just wondered what the point of it was.

This thread is about the Combi boiler, I think on your fire Auto should adjust the fan speed with regard to temperature.

That's what I would expect it to do but it doesn't and never has since new.

I agree with what has already been said, Eco is a waste of time. If you have heating and hot water on the heating takes priority and the water flashes because the heat is going elsewhere. Boost changes the priority to hot water and shuts off the heating fan.

Here are some English operating instructions. German first then English.
