Excessive gas usage

Not what you want when on Holliday but the best place to start is the gas bottle and work back,there is clearly a leak and most probably at a joint.
I hope that you get sorted soon.

If you have a bottle and a rubber tube to regulator check it ,that can perish, in fact in spain it is unlawfull to use one over a certain time. That why all Spanish gas tubes have a date stamped on them. The spanish regulator fitting is the same as southern irish one and you can get a Repsol (petrol company) bottle for about 18 euro deposit and get in back when you are finished. they were around 20euro a refill in May. The price is government controlled and is the same all over. Now about your leak, get a paint brush or a sponge and some soapy water and go along your lines checking for leaks .

Firstly check that there is actually a washer present on the pigtail!
Its not unknown for them to fall off or get knocked off.

If it is any help we have a similar fridge freezer and when in France we use Aires (so no hook up). We usually find that we get between 14 -16 nights from the first 11kg cylinder.
That is water heater on permanently when parked, fridge, gas BBQ and oven /hob cooking.

David I use about a table spoon of Fairy in half a cup of water sud it up really well and use a toothbrush .give. Over every joint that was opened lately.
Did you not have a problems before you left ? Go over all the joints from bottle to fridge with everything switched off and the gas turned on.
Best. Of luck.

Thanks for that. That is approximately what I get in Ireland

Well we are still alive!! South of Barcelona and this cylinder is still tipping away. For how long is the big question. Still no smell of gas. Even asked a few Motorhomers on sites to have a sniff around, literally and figuratively.... and all drawing a blank. Checked a lot of connections and..... nothing. So, onward we go, having a great trip and swmbo already making noises about bigger and better trips ahead. Guess I can sort the non- leak so and keep her with me

The stenching agent in gas will tend to settle over time, sometimes you can get a bottle that has a lot of it concentrated in the bottom for some unknown reason and that produces the rotten smell you get.
Propane or Butane is nearly odourless so to make people aware the gas companies add the smell to help safety.

If it's any consolation, my wife said she smelled gas last night but I had just taken in s citronella candle. I don't get the similarity but when I put it in front of her, she said that was what she smelled.

Fast forward to this morning I thought I was on empty in hidden valley cos the water heater was on strike and I switched the fridge to gas to check and computer said no. The gas was turned on at the cylinder and the regulator. I dodged the advice at reception that I'd need to drive up to 'the crossroads' to find a propane cylinder, the incoming queue and 1pm closure of the recommended store was enough to put me off.

I went out the tenters gate on foot and pretty much across the road was a Glanbia farm shop with flogas cylinders. Obviously I'm not hardcore enough to carry an empty cylinder on spec but I walked over to enquire about propane with the intention of popping back for the cylinder and my wallet, note for the app, they do stock flogas propane red cylinders and open until 4 on Saturdays and are almost across the road from the tenters entrance, the campsite recommended stockists, well beyond walking distance close at 1pm. As it turned the cylinder didn't feel empty and wasn't empty. I've no explanation but the van hasn't been getting the use it deserves recently but the drive down yesterday should have stirred any gas cylinder into action.
