davidmac Posted April 13, 2012 Share Posted April 13, 2012 I have a 40lt onboard LPG tank , the fridge uses 300 gm per 24 hours.If someone could tell me how much 1lt of LPG weighs I could figure out how long the tank will last.I also have Truma gas heating /hot water and gas cooker/ hob but need somewhere to start.

George Collings Posted April 13, 2012 Share Posted April 13, 2012 Where did you get the 300g per day figure from. I ask as fridge gas consumption is highly dependent on the weather.The hotter it get the more gas is used. I take it you really want to know how long you can expect from each tankfull. I fitted a refillable bottle back in 2008 and since have kept a note of how much gas we have used in the 158 nights away. By strange coincidence the figures coincide at 158 litres so its a litre per day. That is with only using electric HU for about 25% of the time when the battery needs a boost. Normally if available we use site showers but otherwise use all the vans facilities at shows or on aires etc.. Link to comment Share on other sites More sharing options...
Airstream Posted April 13, 2012 Share Posted April 13, 2012 Hi, We use approx 1.25 litre per day for fridge, hot water, cooking/bbq and brewing in winter a little more depedent on how cold it is Ray Link to comment Share on other sites More sharing options...
vindiboy Posted April 13, 2012 Share Posted April 13, 2012 I understand that a Kilo of Gas equals 2 Litres, hence a 13 kilo bottle of gas equates to 26 litres . Link to comment Share on other sites More sharing options...
Clive Posted April 14, 2012 Share Posted April 14, 2012 LPG is as near as makes no difference half the weight of water. C. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted April 14, 2012 Share Posted April 14, 2012 George Collings - 2012-04-13 8:19 PM Where did you get the 300g per day figure from? I ask as fridge gas consumption is highly dependent on the weather... The technical data section of my Dometic RM-7605L fridge/freezer's manual contains a gas consumption figure based on 24hrs usage (in my case 380g). This is defined as "Average consumption measured at an average ambient temperature of 25°C in pursuance of ISO Standard". I 'budget' for an LPG usage of around 1 litre per day, but this can reduce dramatically, of course, if a campsite 230V hook-up is exploited a lot, or rise significantly if touring off-campsite in cold weather when the motorhome's gas-greedy heater is brought into play.

davidmac Posted April 14, 2012 Author Share Posted April 14, 2012 Once again thanks for all your replies. Having just started with the motorhome I am pick up on any problems before we set off on any long trips. AS well as the refillable tank there is also a 13kg bottle plus room for another. LPG seems available at many filling stations so will just go with 1 bottle for emergency use.Based upon usage of others we should have no problems.
