We have a 1984 Hymer which is still, mainly at 50 mBar. The fridge heater and hob all run off the 50. We had a new water boiler installed last year which runs at 30 mBar and has an inline reducer to handle the 50 down to 30.
We have had problems with the aluminum gas hob heads burning out and melting. (IF you spot it soon enough they are just difficult to remove, if not - well nigh impossible.)
We have a GasLow system with 2 11kg bottles.

I would like to know if it would be advisable to drop the whole lot down to 30 and what the implications are for the heater, hob and fridge. If so, is it a DIY job or can anyone recommend someone to do the work.

Any advice, thoughts etc most welcome

Thanks

I presume with the Gaslow system you are still using the old type continental regulator and not the latest 30mbar one. If that is the case I can see no reason why your hob heads are burning out? Even if you were supply wrong pressures to your appliances I still do not think it should burn out your heads but I am no gas expert. Cannot see you have anything to gain by going to the expense of changing the jets on your older equipment but no doubt someone else might know better?

Does the old style 50mb work on butane or propane?

Another thought. When they first introduced the euro standard 30mbar regulator I inquired if you could retrofit an older van. The answer was no!
It is possible you will not be able to change the pressures on your older equipment without actually changing the equipment.

Thanks for the replies.

The system is currently using the 'original' 50 mBar regulator. When I say original, I mean the one that was with the van when we bought it.

The van has a GasLow system and so uses Autogas/Lpg.

After having done some more research today I have found a 37 mBar regulator that works with an adaptor to fit the GasLow bottles. If I were to fit this, would it have any adverse effect or would the gas hob 'benefit'?

A gas engineer at a certain MotorHome outlet seemed to think it might be ok, however I would have preferred a confident answer!

Hi I would say try it, what with your problems with the aluminum gas hob heads burning out and melting that is not good! after all what about when you run on Camping Gaz you go from 37 down to 28 it still works ok. Bob.

But you also, I hope, changed the regulator? 37mbar was the pressure for propane and 28 for butane. I assume the appliance jets were designed to work efficiently at these pressures for the respective gases.
