Propane/Butane
I normally use Repsol Propano for my boiler and heater. However, the supplier today only had Butano. Now both have the same connections but everything I read says it needs a different regulator. They both have the same UN1965 label attached. Does anyone know whether they are interchangeable without changing the regulator? A quick test on a stand alone gas heater worked fine but I am concerned that there may be pressure issues.

Re: Propane/Butane
Never, ever worried, but ignorance is bliss! Seriously, notwithstanding the info you have, we've interchanged the bottles for 15 years now without problems.
Maybe a techno can impart more safety info?

Re: Propane/Butane
In the UK butane and propane appliances work at different pressures. That is why, in the UK, the fittings on the cylinders are different for butane and propane such the only the correct regulator can be used.
I believe, that here in Spain, there isn't a pressure difference or that the difference is very small, so they don't need different regulators. As you have noticed the standard regulator fits both butane and propane cylinders.

Re: Propane/Butane
Very quickly..you get more bang for your buck with Butane in Spain. Propane needs to be used at a much higher pressure than they use it here so it is running much under par all the time.
Propane however will gas at much lower temperatures than butane so is better for outdoor applications. Butane will not gas below about 4 degrees Celsius so on a very cold night outdoors for instance..nowt will come out. Jet sizes in appliances are the same for both gases so in summer butane on your boiler outdoors will be fine but it does cost more per cylinder but should last longer. I do not recommend propane for kitchen use or in estuffas ( it will work however) as it does not provide the same heat output if you are using Spanish kit. It is completely different in the UK

Re: Propane/Butane
As an aside, Butane is definitely heavier!!
