Underslung LPG newbie

[JulieH]

Hi All. I recently purchased a Swift Voyager with a 40litre underslung LPG tank. We filled it up before spending 2 days and nights off grid. We had a full size fridge freezer running, along with the heating (nonstop) and a small amount of cooking. Our indicator is telling us we have used half a tank. Does that seem excessive? I'm a total newbie to it but just expected it to last a bit longer than that. Was just a bit concerned that we have a 6 night stay on a site booked and the gas wouldn't last - although, it will be warmer weather and we'll be hooked up so the fridge can run on electric. Thanks

The gauges ( level indicator)are about as much use as a chocolate fire guard.
Wait until the red light comes on as you will still have approximately 1/3 of a tank left.
Do not become obsessed with the gauge lights they really are just an indicator and definitely not a calibrated gauge.
I wish we didn’t have to sell them as they cause more problems than anything else, it the installers aren’t shorting them out at installation then the customer is on to us about faulty gauge
I would love to stop selling them tomorrow

Heating will guzzle it, our heating uses about 500g an hour on gas.
Fridge uses about 200g an hour.
Cooking... really depends.

You are probably using a lot less than implied by the hopelessly inaccurate gauge on that underslung.

Unfortunately the only way to understand how much lpg you have used, relative to the useless gauge, is to start fully filled, use a bit, look at display, and refill.

My 25l original tank (which means about 21l actual due to the 80% fill levels), I've never got more than 12l refilled when it's just gone red.

Because the cylinders are on their side, the internal float gauge has limited scope for movement. Makes the thing so inaccurate that a chocolate fireguard would be more useful.

Sounds about right tbh if you had the heating on all the time.

NB Automatically, the filler wont let the tank fill to 100%, the liquid gas needs an ’air’ gap to work properly

Fridge uses about 200g an hour.

Christ, what sort of fridge you got... our large twin door fridge/freezer used 380g PER 24 HRS...
But yes agree the killer to gas usage is the heating...

Sorry I meant per 24 hours, label says 220g actually.

To come back and answer.. you say 6nights on EHU!
Can you not run your heating on leccy ?
Even if you can't I would be happy to stay 6night with my 30ltr tank using heating wisely, especially as you say fridge will be on leccy.
You could always take a fan/oil heater to plug in...

Yes, we have a radiator to plug in but it will be summer time so probs won't need heating anyway.

Even in deepest, coldist winter we do not have heating on all night..
You will be surprised how toasty it is once in bed..
Does not take long to reheat van once you are up..

Fair point actually. Our old van had a diesel heater and we would run it day and night for pennies. Just need to be more mindful with the truma heating. Another learning curve

We have 2 tanks one 25 and one 30 litre we Have been in France since 19 Feb. Gauge on the 30 litre shows 3/4 full 7.5 mtr A class heating on 24/7 as is the fridge. The gauges are notoriously inaccurate as you will find out the next time you fill up with LPG. Van parked up in our garden no hook up.

He said a large fridge/freezer so more like 500g (1 Lt) 24hr.

That's another point I think missed up to now - 40ltr tank gives what 16kg of gas at 80%?
