My boat uses butane rather than propane and this has frozen up but other than that everything is ok and now it's getting light it is warming up a bit and I think it's going to be a lovely sunny day. Why not put the butane gas bottle next to your stove to let it warm up? That's what I'd do. I just use a little one-ring camping stove on the few days a year it's a problem.

I don't understand why the bulkhead regs are 30mb not 37mb.

I've never had this problem before but always used propane. It was the regulator which froze due to water ingress not the gas freezing.

This regulator is only a couple of years old it's just a shit quality one. Buy cheap, die cheap.

Very bad yes. Makes me glad I have always turned away from having candles or oil lights in the boat as well. Boatt Safety man did pass the boat last week (yaay now have a Gold License) but suggested I get another regulator - he was right. It works fine now but that night it froze up. I was unaware of them failing open like that. My phone tells me it is -1C in Newbury now, here in the frozen wastes of Darkest Scandinavia it is just -2C. But did snow a fair bit overnight. When I was in Northern areas during winter Ross, it was the darkness bit that got to me, more than the snow and cold ( in the winter when the Baltic was frozen we used to go to either Kirkenes or Murmansk to load) (incidentally I see it was minus 21 in Kirkenes this morning)

This regulator is only a couple of years old it's just a shit quality one. Is the regulator outside on the bottle? I ask because they usually have a tiny vent hole which, if installed with the hole upwards, can fill up with water and then corrode and freeze. Hole upwards sort of looks the right way up, but isn’t. The solution (for the new one) is to mount it on the cylinder the other way up (hole at the bottom) then it doesn’t fill up with water...

I don't understand why the bulkhead regs are 30mb not 37mb. Different pressure for butane vs propane.

These are the mornings when I’m glad to have the keyfob remote for the Mikuni on the bedside table. The stove was still going but it was bloody cold in the bedroom. Press the button then arms back under the duvet until things have warmed up a bit! These are the mornings, when I’m glad I have an obedient wife, that I can send down the boat to press a button.

This one says propane butane or mix at 30mb but I think the cooker is jetted for 37mb (propane). Would it work? www.bes.co.uk/caravan-low-pressure-regulator-straight-20568 As for the drain hole I am aware of it but for some reason this regulator has a gauge which is mounted in such a way that it points downwards when the regulator is installed in the correct orientation. It's tempting to mount it so the gauge is visible but only way to do that is sideways. Bit of a pile of junk. I bought it for another job not for this boat but it was only one I had as original one was nackered.

I like Telemachus remote control version. I did similar with a phone control but when on boat a key fob does seem less complex. Easy to implement with a £6 remote control relay circuit. Not sure if it would go through a steel bulkhead though.

I bought it for another job not for this boat but it was only one I had as original one was nackered. Having done a bit of research it seems that the eu have decided that, rather than having separate pressure standards for propane and butane, they will enforce one standard of 30mB. Apparently it doesn’t really make any difference.

Apparently it doesn’t really make any difference. It does if you have the wrong jets fitted. Either hopeless or CO poisoning. I knew what you meant though. Good idea to make the fuels and jets the same. I expect it was a monopoly butane situation, those butane refills are eye wateringly expensive.

Apparently it doesn’t really make any difference. It does if you have the wrong jets fitted. Either hopeless or CO poisoning. No actually I don’t think so. Butane was supposed to be 28mb so 30 isn’t really going to make much difference. Worst case might be a bit of flame lift off which, with flame rectification supervision could I suppose cause the device to shut off. Depends on the device of course, and many have quite a wide range of permitted supply pressures. Propane was supposed to be 37 mB so a fair bit less pressure at 30. However it’s important to remember that the mass flow rate of the gas through a jet isn’t proportional to the pressure. So whilst the pressure at 30 is only 81% of 37, you would (at a rough guess) get 90% of the mass flow. So a bit reduced? Yes. Hopeless? No. And no CO poisoning. With the move to everything being 30mB these days I wouldn’t be surprised if manufacturers have done nothing much except rebadge, and retain compatibility with both the old and new pressures.
