Water to tank for heating

bluethunder

I picked up my van last weekend and very happy with everything. I've had a good look around and everything is in good working order. There's one thing i'm hoping you guys might be able to help me with.

I have a fresh water tank underneath the van. It then has another smaller tank inside the van which is for hot water, heated by gas. I can get the gas to light but i'm not sure if there is water in the tank, in fact i'm pretty sure there isn't. My question is, how do I fill this tank? I'm assuming it draws supply from the fresh tank but i'm not sure how. The small tank has a valve at the top to release air if it is airlocked. Can anyone tell me what to do to draw water into the tank?

Cheers.

Hi what kind of system is it?

Most of us will have the Truma boilers. With this to make sure there is water in the boiler your run your hot tap until it stops spluttering. Once you have done that there is water in the boiler.

Your system sounds a bit different to mine but my guess is that the procedure would be the same i.e. run the hot tap (or the mixer tap all the way to hot).

Oh and BTW congrats - enjoy. We are approaching out six month anniversary as campervan owners and loving it.

Agreed - run the hot tap.

Thanks guys. I don't have a Truma model, I can't remember the make but it's some acronym like ABG or ATG or something like that. Anyway, so you think running the hot tap until there is no spluttering will mean that the tank is full? I just want to make double sure because if I fire the gas for hot water and there's no water I could cause a serious problem! I assume I may also have to fiddle with the air release valve.

Any photos to let us see what boiler model might be ?

I'll try what you suggested tonight and if it doesn't work i'll get some photos and post them up.

Update: got the heater going last night. Filled up the fresh water tank until the overflow started spilling. Then I ran the hot tap and after much spluttering and pumping I figured the heating tank was full. The gas lit and in about ten mins I had warm water!

Now I just need to sterilise the tank and all the lines and i'm ready for road.

is the heater mounted up on the wall? and you can see a little pilot light in it? Often known as a "Geyser" .
