    Liquid Propane Weight

    This site: http://www.pmak.org/public/propane_facts.html states the following:

    The specific gravity of propane liquid is 0.504; water is 1.

    Therefore 1 litre of propane weighs 0.504kg.
    19.5 kg = 38.69 litres

    Or do as I do work on the basis that 1Kg = 2 litres - then if you want to err on the safe side just take a litre off the end result.

    So by my reckoning I paid 58p ltr for autogas yesterday at our local shell garage but last week I paid 20 quid for a 19.5kg bottle of propane from the builders merchants which equates to 52.6p ltr by the 2 for 1 formula which makes bottled Gas the clear favourite to use in my RV while Im fulltiming on site through the winter months.
    Funny , I always thought Autogas was half the price.
    Interesting.

    Hi Tony

    £20 for a 19.5 kg bottle is a good price. Our local Calor dealers sell the 6 kg bottles for anywhere between £17 - £21.
    We use Autogas in our Gaslow system, our local BP garage is now selling it at 63.9p per litre.

    Hi Tony that is a very good price :thumb: a 12 kg bottle here costs £23 exchange or a 15 kg £25 exchange -- Now this surprised me ---the 12 kg & the 15 kg bottles are the exact same size only difference is in the weight- :Rofl1:

    just exchanged a 15kg calor butane (for the cabinet heater at home.)

    £27 from the local BATA store.:Eeek:

    less £17 for the bag of scrap copper cable at the local scrapyard...:thumb:

    £10 for 15kg.....beat that. :Rofl1:

    dont forget the VAT difference......17.5% at the pumps(road gas).....5% for bottled.(domestic gas)

    Hi
    What brand of propane do you use ??
    I just paid £30 for 19.5 Calor ,it get cheaper as you get larger bottles (the 47Kg is half the price,-- per Kg-- of 13Kg

    I use Flo Gas mainly because I had a few of their empty bottles kicking around to exchange.
    I think I paid round about £50 for a 47 kg just before christmas.
