Hi;
I'm not certain but I think that the regulator / adaptor that sits atop the gas bottle in Spain is of a different design to that used in the UK. There is therefore the possibility that any heater purchased in the UK may not be compatible with the style of regulator used by the Spanish supply companies Repsol and Cepsa...
OK...in answer to your main question....I have seen portable gas heaters in both AKI and Brico-Depot Stores. (Brico is the Spanish arm of B&Q). AKI's website aki.es works best in IE. Brico's website is a nightmare to navigate; so much so that I wont even bother to put a link in to it half the time it doesnt work at all...just see for yourself!
Whether or not they carry the woodburning look-alike versions is something you will have to investigate for yourself.
Repsol and Cepsa are the main distriibutors for the integrall gas bottles and you will need to set up an arrangement with them for the purchase of your first bottle. This may require the production of an NIE...
If you would pefer a fixed installation after all can I suggest you contact http://www.meridianstoves.com/gas-fires1.htm They are based near Alicante and may be able to help....
