Hi just wondering I am thinking of fitting a big 70 litre LPG tank in my motorhome for everything but running the van on but I have been told the fridge works of the fumes where as the heating and cooking aspect works off the liquid I am new too this and could do with some advice because my idea is get the 70 litre LPG tank for everything but the fridge then get 1/2 solar panels for the frige during the day and 2 6/7kg gas flows for the night this is my idea is there a cheaper easy er way round it ? And bearing in mind my locker only FIts 6/7 please help much apriceated (At the moment been running of english calor in Spain anywhere to fill up as its my first time didn't think it would be a problem lol but anywhere to fill would be helpfull)
 
hi .fridge cooker and heating work from the vapour /fumes . the engine runs off liquid . but it isnt wise to run both systems through one tank. as you dont want to run the motor i see no problems . google fes gas or someone like that.

Thank you ye we don't want to run the engine from it so we should be ok then the tanks is actually out of a car I had gas converted is that still ok to be used ?
 
hi, no that is designed to take liquid from the tank. unless you are properly conversant with it . better get a proper vapour tank. there are ways round it but for your safety better you visit the right people . do not just fit your car tank . liquid going to appliances is highly dangerous .

Thanks for that yes I would get it done professionally fitted and I suppose I could always ask the garage what they thinks best its always useful to get as many opinions as you can get I suppose better to be safe than sorry but thanks again much apriceated :)
 
Hi, The Murvi has a 10k.5 g fixed LPG tank for the gas hob & fridge. On a six week trip 10.5kg ( about 20 litres) lasts about 32 / 35 days.
Unless you going to do full timing 70 litres seems a lot.

Hello
I agree with Dezi 70 ltr is an awful lot of gas for a motorhome unless you are full timing. I have 2x 11KG about 42 ltr refillable bottles. I use my van winter and summer for 2 to 3 months at a time and never run short of gas.

I don't think you should use a LPG liquid tank for running apliances. There is some info on the net of how to convert/modify a liquid tank to make it a vapour tank but I advise against it.

Any pressurised container is tested/certified. As soon you as you temper with it you void this.

But there are so many ready made tanks and upright tanks (looking like conventional gasbottles) out there, it's not worth taking the risk in my opinion of getting it wrong when butchering a gas tank. Not even talking about insurance complications if something goes wrong.

BTW engines do not use liquid gas to run. They have a vapouriser under the bonnet to turn the liquid gas into fumes. The vapouriser is connected to the engines cooling system and needs the heat of the coolant to vapourise the gas. That's why you need to start the engine on petrol to generate some heat in the first place to make the vapouriser operational and switch over to LPG.
And yes, there are liquid injection LPG systems as well but they also engine heat to vapourise the LPG once it leave the injectors.

Thanks for the info guys I put this up for my dad so I will let him no ASAP because we are thinking of becoming full timers but when I show him this I'm sure we will to a conclusion thanks again
 
Liquid propane sprayed into an open flame burner eg gas hob, will cause an explosion. That's why you must have the correct bottle with expansion space and correct regulator.
