what is really the most economical in a choice of gas central heating (combi boiler), oil central heating, and between wood burning stove (if you paid for the fuel) or a gas living flame wood burner style stove - or just a traditional fire in the fire place.
I am always told gas is cheaper than oil but I tried oil for a while and sure it was cheaper.
I don't know what His Brightness was up to at that time of the morning, but I have to agree with him ;o)))
If you want something different, wood pellets (boiler) is still cheaper than all of them....... after you've paid the rather high cost of the installation.
