What is the best way of heating the home in the winter ??

Air con is the best and cheapest. Electric oil fired rads  and  calor gas the most expensive. If your on a low 3.3kw tariff you will trip out a lot if you use electric heaters. We don't bother going for the coldest months over the winter. It's just too cold in the house for us

We bought a calor gas heater. Very cheap to run and keeps the apartment nice and warm. Better than the built in air con/heating. Warms up quicker and is cheaper. We did it properly and obtained the correct certificate from the gas people.

Thanks everyone...we're wanting to move over there so wasn't sure what to use x

If you've got a fireplace, or can fit a free-standing log fire, then that is far and away the most effective way of heating your house. 

There's a few minutes work each day in cleaning it and re-stocking the log basket, but the amount of heat a proper log fire produces is excellent. Our's is rated at well over 20 kilowatts. The thought of what that would cost in electricity or gas just amuses me!

No room or availability for log fire in our apartment. For a holiday home the gas fire is great and so easy and convenient for a few weeks in the winter. Also we can store it away when not in use. 

What months are so cold and how cold are we talking about i would think England is colder ! 

End of November to end of Feb are cold. During the day outside is tolerable. However Spanish homes are not built for cold and are difficult to heat and retain the heat.

I liked it during the day but coldness of the house was too much. In the UK we have energy efficient homes with central heating. 

You living in Spain?? 

No. If I was i would probably invest in central heating. I do about 2 mths a year out there. Lock the house up end of November then open it up Feb 1/2 term
