    I have a two-panel sun for heating the room. And it irritated me when replacing the cylinder that it is not completely empty! There was something left, sometimes you could even feel a lot when the cylinder in your hands was opening. I found a way to empty it completely. This only applies to heating under the sun, or perhaps in a stove. Well, I set up an ordinary fan, one to cool down in the summer heat over the sun. I directed the airflow to sweep the escaping hot air down to the floor. Now I have heat all over the room and the cylinder burns out to the end. I think that this leftover gas does not burn out because the cylinder bottom temperature is too low.

    EDIT: Just don't let someone think of heating the cylinder on, for example, an electric heater!

    You just need to heat the room in which you breathe the exhaust fumes.

    Read the instructions of this sun. It says that it is forbidden to use it indoors ...

    What is it for? For heating the yard?
    I have been warming myself in the workshop for 10 years and I have no problems with breathing. A minimum exhaust ventilation in a suitable place is sufficient.

    You combine like an uphill horse. I also had a problem with gas devices not completely emptying the cylinder (mainly the radiator). The solution to the problem turned out to be very simple. It was enough to put the cylinder upside down and place the radiator on the floor. All the liquid and muck left on the bottom of the bottle drained out of the nozzle (like a spray). The flame was much bigger. It turned from blue to yellow and soothed the radiator. The adjustment valve increased the resistance to turning the knob.

    It's good that you are alive. After such "saving" treatments, you can give your body a good one.

    I spend a lot of time in Masuria. There I use four cylinders. I was always annoyed with leftovers in the cylinders. Years later I came to the conclusion that there were leftovers non-flammable / not flammable and when refilled the distributor added it to the net weight, which I pay for. Now, after firing the cylinder, I turn it upside down and pour out the remnants - water, crap - attention, it stinks a lot, it should be done on the sidelines.
    At least someone who buys the gas for me won't pay for the crap they don't burn.

    The gas simply contains some compounds other than propane and butane and they aggregate at the bottom of the cylinder. Like water in a compressor.
    It doesn't make sense to burn it out by force, because you don't know what it is.
    The idea of pouring it out is pretty good but when I poured it out in front of my house it stank for another week ;) .

    Gentlemen, the failure of the cylinder to the end may be caused
    1 as in the author's case, he rarely uses the cylinder, propane is lighter goes up and slept butane falls to the bottom butane itself burns poorly and stinks more.

    2 pure propane is expensive, so some producers play with propane, butane and derivatives, especially in summer, it can be noticed because nothing will freeze, the same applies to home tanks, if you order gas in summer, they can bring anything and in winter they can't because they will not pump it out cisterns, when the gas is bad, it happens that the pots are smoky, if point 1 is excluded, I advise you to change the cylinder exchange points, add a few zlotys and have peace of mind

    I just ran a little test, here are the results:
    0.5l of water at room temperature, boiled in a kettle on an optimally selected burner.
    Natural gas consumption is just over 0.013 m?.

    The cost of this, taking into account the cost of gas and the variable network fee (a fixed one, I would pay anyway, so I omit it) is approximately PLN 0.4 per liter.

    Has anyone done a similar calculation for the current? :-)


    Measured - 1.7 liters of water boiling = 0.193 KWh


    So 1 liter - 0.11kWh. At 65 [g / kWh] it gives 7.4 [g] for boiling a liter of water with electricity.


    The electricity is cheaper than you wrote. Currently, Wrocław costs PLN 0.53 per kWh in the G11. (no fixed fees - because these are still paid for the TV set :)

    The gas in cylinders can be of mediocre quality, with the addition of water, etc. So switching to electric is only a plus:
    = no cylinder changes required
    = expelling gas elements from the house
    = increased security

    Possibility to switch to 2nd tariff electricity - I recommend. If the coffee is before 7:00 am, you can still get a cheap tariff - PLN 0.28 per kWh.

    Gentlemen - weigh the cylinders empty and full!
    I use "alleged" 11 kg cylinder for the stove at home
    We have its tare weight on the cylinders - correct after emptying,
    But I have already weighed 2 cylinders straight from the distributor (wrapped in foil, etc.) and unfortunately I find that the gas itself is there .... 5 kg
    Another change awaits me in a few days - I will see how much will be in the next one


    Very interesting information. I wonder how much of these 5 kg is gas ...

Topic summary

The discussion revolves around the challenges of maximizing gas usage in 11kg LPG cylinders for cookers and forklifts. Users express concerns about residual gas and liquid left in the cylinders after use, with some suggesting that the remaining substance is not gas but rather a liquid, possibly butane, which does not burn efficiently. Various methods to extract or utilize the remaining gas are debated, including turning the cylinder upside down to drain the liquid. The conversation also touches on the economic aspects of using LPG versus electric kettles for boiling water, highlighting the inefficiency of gas in such applications. Additionally, the quality of gas and its composition, particularly the presence of butane and propane, is discussed, with recommendations to consider using pure propane cylinders for better performance and less residue.
