Do houses have plumbed in gas supply in Torrox pubelo?

I doubt underground gas, Butane or Propane gas is used a lot here in Southern Spain, it's good for hot water and cheap as capped by the government, at the moment about 18 Euro a bottle, you are talking of about £50 in the UK. Many people upgrade to electric water heaters but costly to run and you are lucky to get a good long shower from a 75 Litre one, the liquid gas creates double the heat temperature and no problem running a bath as constant heat. You need at least a 100 litre water heater for a bath and the next person might have to wait at least an hour for the next one. The gas bottles might seem primitive but work well.   

Thanks for your response.  I was wondering what folks were using as I seen some adverts for properties which have gas hobs in the kitchen and I was trying to figure out if this was mains gas or a bottle hidden in the kitchen somewhere.  I guess being in south of Spain then maybe it could be augmented by a solar water heater on the roof but I guess that needs space and is perhaps not the most attractive addition to a terraza.

My guess the gas bottle hidden away, solar more popular now since dropped Sun Tax. https://www.reuters.com/article/us-spain-politics-electricity-idUSKCN1MF1T0

Electric cost here high, I think about double UK, cheapest energy those gas bottles, Air con very important here in South of Spain the modern split 'inverter' types cheap to run and in reverse give you very cheap air heating in winter running as a heat pump. Heat output about 5 times energy input. .
