Hi Beachcomber
Research about any grants, tax incentives, any special deals from your own power company or supplier, if there are any reseach programs or studies that will be a benint towards your doing this. I don't know what they're doing in Ireland to work towards pushimg energy saving but I do know here in the US it just keeps getting worst as far as any incentives go. It's almost like we're working backwards, opps, we are working backwards. I just bought a Totoya Prius, a Hybrid, & we can only get 1/2 the tax incentives that the government first offered & there doesn't look like they'll be any in 2007. Go firuge, & with all the screaming about the need for alternative energy sources.
Good Luck
