    Off grid heating

    I understand this could be how long is a piece of string. But I want to wild camp early next year in Scotland. I have gas heating and 3 fan speed settings. I realise the leisure battery will power the fan. If on low how long would it be ok to run it? Is it likely to drain the battery very quickly so probably not worth using? I’ll definitely be taking a hot water bottle and wouldn’t leave the gas heating on overnight. I have a solar panel and would be doing some driving during the day as well so will be topping up the leisure battery. Many thanks

    Hi! I can't remember what van you have but simply boiling a kettle on the gas ring generates a lot of heat. The boiling water simply left in the kettle will continue to radiate heat too, so fill up and reboil if you filled a hottie bottie! Take two for Scotland in early spring!
    No idea how long a fan will run as it depends on what size the battery is, and how much heat you need. Generally anything generating heat of some sort will quickly deplete battery power, but having a relay and solar will definitely help.

      when we were in Scotland ( up in the snow covered mountains
      we used the heater to warm it up in the mornings and put the kettle on for tea most of the time it was not too cold in the van so .... as we are still using the same gas bottle it probably does not use too much

        You are concerned about the battery, not the gas, if I read your post correctly. If you have a solar panel and you drive at least every other day you have no worries about using the heater. Just use it whenever you want to - the heater fan will not take a lot of electricity, it's the gas that makes the heat not the battery. Are you sure it has three fan speeds? They usually just have low and high. Anyway just stick it on low speed for the evenings and if you need to, for the morning. Driving will recharge the battery and so will the sunshine if there is any. The bottom line is that it is nothing to worry about, if the leisure battery goes flat you will still be able to start the engine and drive off.

          Don't know how big your battery is, or the solar panel, or what sort of electrical drawer the heater fan takes - but as a guide, I have a 110 aph battery and a 200 watt solar and can do 3 nights easily without moving the van over New Year. Actually, on thinking about it, I hadn't had the solar panel fitted last New Year and I stayed 3 nights! I didn't have the heating on all the while, though - in the morning for an hour or so to facilitate getting up, washed and dressed, and for a few hours in the evenings. I have a Truma gas blown air system.

            Thank you for all replies. Sounds like I’m ok for an hour to defrost! I’m sure I won’t be too cold. Hot water bottle, thermals and a springer spaniel . Touring Scotland is one of the main reasons I bought my Surf. Ireland will be next on the list after Scotland.

              Hi according to Propex the heatsource 2000 consumes 1.6 amps that is ignition and fan, so from that you can work out how much battery use the heater will use (negligible). I would suggest what you ought to do is convert the habitation area lighting to LED.
              I hope you enjoy Scotland as much as we have done in the past and will in the future.

                That's because we socialised in my van....and the battery went flat on the third night, lol. Note..I didn't have a solar panel.
                Anyway, I'm no expert but would expect all will be fine with a solar panel and driving every day.
                I was in the van today preparing for the weekend and according to the meter on my newly fitted solar panel it was providing 14 volts to the solar controller despite the dark clouds and heavy rain.
