I just had a LPG installation done in Ribeira, Galicia, Spain and I must say I am extremely impressed with the company who carried it out. I had an appointment at 9:30 this morning (I had booked it before we left the Canaries) and they were waiting for me. Van in, conversation about the options and in 2 hours all finished. The filler has been fitted inside the fuel filler compartment, so no worries about taking out the bottles etc. The bottles themselves are composite rather that metallic and have an initial 10 year life before a visual inspection and then 10 years more. These containers come from the UK so I imagine many of you already have them. 2 x 24 litre bottles with an automatic switch over valve and impact security system. Level indicator on each bottle. After the completion of the installation, the guy took us to a gas station nearby to fill the bottles and check for leaks (none, fortunately) and show me how to fill them. Excellent service an all for €1.340 which I thought was reasonable.
