    I think I already know the answer to this, but thought I'd ask someone in the know!

    Is it possible to run a heater (e.g one of those tubular heaters everyone seems to be getting) off your leisure battery?

    I assume it'd drain it quite soon, but wondered how long you'd get from a full battery.

    If not, then what do you guys do? Run it from your house with an extension??

    Thanks in advance.

    with the tube heaters well the 120watts or less ones, depending on you battery size and how good it is.

    as a rough guide a 110ah would run one for about 2 days.

    Wow thanks! That's brilliant.

    Think my bat is 110ah, so you're saying I could easily run a 120w tubular heater off my leisure battery overnight? Say 10hrs.

    It recharges off my van alternator so would recharge as I drove along.

    Would the wiring be easy to do???

    it should do, but not 100% sure as i havent working it out for one of them.
    if possible, it would be better to run it from the house if you can do it safely

    the wiring is easy if you use and inverter, them come fit the fittings to fit to battery

    120 watt (heater) divided by 12 volt (battery) = 10 amps.

    120ah leisure battery should last 12 hours at 10 amps per hour.

    110ah leisure battery should last 11 hours

    85ah should last 8.5 hours.

    I think.

    I've just got a new batt for the van, thinking of putting a splitter in to use the old one for a bit of backup for pump, can I also stick a tube on it for o/night?

    Will be interested to see if this works, are you using 12volt heaters or are they 230 volt through an inverter, I would be carefull about running the battery flat as you can easliy damage a battery
