Re-fillable gas in Spain

Stations to re-fill your re-fillable cylinders in Spain are not as prevalent as they are in France and Portugal so a little planning is necessary.

We have been here a month and my 21 litre Gaslow has been showing empty for the last two weeks so panic was setting in.. Drove 73 Km to Jerez and guess what?    It took 13 litres to fill it-----Pftttt I bet it is empty next time I go.

if you are on sites and elh why do you need gas

We have to eat in occasionally and I hate salads  

We have to ring elec plate when on hook up use that and eldc kettle snd small plug in oven

Had the same problem a couple of weeks ago when the heating turned off because there was not enough pressure to run it in the bottle I had connected to so I changed bottles and it worked.

Went to fill up on the way home and only got 15lt in the both bottles, so the first one was no where near empty, very strange and annoying.
