I have had a boiler in my van for a few years very simple make sure you us some thing like car radiator hose which you can get from car parts or online make sure that you use gas paste on joints and check with gas detector spray for leaks It will bubble if their is a leak , beware that l p g is heaver than normal gas so hangs about at floor level if there is a leak. make SURE YOU CHECK IT REGULAR make sure also you inform your insurance company if you don't and it goes bang you aint coverd
its not worth the risk IMO...the only option for a safe proper hot water system is a diesel heater........
I think what dazmond is trying to tell you is very important.
I can say from experience having used gas for two years that it’s definitely the cheaper from an initial cost point of view. But I know a fellow window cleaner who’s Boiler set alight inside his vehicle. (Didn’t something like that happen to you Daz?) there is an inherent lack of safety with these cheap Chinese boilers and using flammable gas.
I’m currently switching over to a diesel heater so i’m in the Unique position where I’m using both a gas boiler on one pump and a diesel heater on another unique position where I’m using both a gas boiler on one pump and a diesel heater on another. Having a contractor with me regularly I just don’t feel it is a safe option using the gas. So as soon as with you stop these 19 kg bottles we are removing the gas water heater
Since you’re looking to use an option on two pumps I presume that you have either an employee or a contractor or a mate working with you. What would be the implications of being sued through burns from a gas boiler going up or a van fire on a customers drive? Or a Road traffic incident involving your van?
This is why for me another method is the only way forward. And long term I could have saved myself the money put into a gas boiler if I had just gone for a safer option from the start. Worth considering too if you want to save money
