Basically safest to simply say a gas heater with a flame is an absolute NO NO in a confined space, as very high risk of lethal Carbon Monoxide poisoning from the combustion process! - you die without knowing anything is going wrong, as it's a colourless, odourless gas that builds up from the floor level, making you drowsy then killing you in your sleep!
There are a few CATALYTIC gas heaters available with no naked flame combustion which claim to be safe. I'd still fit a Carbon Monoxide alarm to be doubly safe!
Inverters to provide 240v power are best avoided, as inherently inefficient, and will 'waste' your precious limited battery capacity! Far better to use 12v appliances, a number of duel 12v/240v TVs available at moderate cost, look at the Cello camping range.

Forget any notion of heating or cooking appliance running off 12V battery, they will kill it dead in no time!
Always worth bearing in mind, with ordinary (lead acid type) leisure batteries, you only really have HALF the stated capacity available for use! If you discharge them beyond that point you risk irreversibly damage them! Also, as they get older, the effective working capacity diminishes too! A good quality battery, well looked after, may have a working life of 5 or 6 years before it's too 'worn out' to be much use. Your 55Ah battery should from a practical point of view be considered a 20Ah battery, which translates as 1A (or 12W) of power for 20 hours use, or 20A (or 240W) of power for 1 hour use. Of course, once the battery is discharged, it NEEDS recharging near immediately, because it will risk damage being left for very long in a discharged state! All 'technobabble' to you I'm sure, but may just give some insight into how marginal a small battery is in practical terms if your sole electrical power. For instance, your battery would run my 12v TV for maybe 7-8 Hours total, 10 hours at max! - and that's the TV alone, you will need lights too!
Probably best to keep your battery power for lights and phone charges only if going 'off grid'! You could buy a bigger battery and a solar panel, and a 12v TV, but suspect that may impact your budget too much! ... then again EHU only pitches resolve all your problems!
