It is well documented on here Calor are experiencing great difficulties in meeting demand for new touring size cylinders. IMO this is not the Dealers fault. Don’t forget the cylinders are rented not sold.It is the gas you buy
In many cases yes, but not always. There have been several different bottle connections over the years, but regardless of which UK sourced cylinder, you should be able to get the correct pigtail.Are the connectors the same for different manufacturers (ie will a caravan pigtail be suitable for Flogas and Calor etc)?
That could be difficult for people that live in Scotland and tour, but for those who venture north of the border it should not be a deal breaker if they take two full bottles with them. Of course if they are going off grid it could be more difficult. We had no problems with two 6kg Calor when spending a month in France although we had EHU albeit low current at times. but we would travel back still with a good amount of gas left.I thought the Nationwide availability of Flogas was sparse particular Scotland?
IIRC most Propane Calor or Flo uses the same pigtail, the one for Butane is different. However confusingly, the Flogas Gaslight (propane) actually uses the butane style pigtail.Are the connectors the same for different manufacturers (ie will a caravan pigtail be suitable for Flogas and Calor etc)?
I have 6k calor and 6k flogas both propane and use the the same pigtailIIRC most Propane Calor or Flo uses the same pigtail, the one for Butane is different. However confusingly, the Flogas Gaslight (propane) actually uses the butane style pigtail.
Historically Yes.Any reason why the powers in charge decided that there should be two different types for pigtails for gas bottles instead of one universal pigtail?
Most modern UK and EU caravan gas appliance's will use the dual 30mB standard. This actually means if you heat a kettle on butane it will heat up a little quicker than if you used Propane. The reason is the Butane has a higher calorific value than Propane when supplied at the same pressure.
Historically the issue was equalised out becasue butane was supplied at 28mB and propane at 37mB. However the ratio of the caloric difference between Butane and Propane is not the same as the ratio of the pressures, becasue density of each gas is differnt you have to be familiar with the the gasses Wobbe Index.
There is a difference, becasue the propane has a lower calorific value per volume compared to Butane (in its GAS phase at matched pressure), so using the 30mB bulkhead regulator, technically the kettle will take longer to boil on Propane. The difference is not massive and you'll not really notice the difference in practice, and where an appliance uses a variable valve driven by a wax thermostat it will largely automatically compensate for the difference.Thanks for the explanation. I understand about the pressure for different uses, but now in a newer caravan I suppose it would not have made any difference as gas would go through the bulkhead regulator.
