Geothermal Heating ?

This site Alternative Heating & Cooling Ltd., Skibbereen, Co Cork, Ireland is one of the many providers of the increasingly popular Geothermal Heating. It's something I have considered then dropped - but I am looking into it again. It could cost more than double the price of conventional heating systems - but you should get the extra cost abck in savings in a few years. Especially if oil prices keep rising. It is an attractive option - but there is always the fear of the unknown.
