The cost per litre is euro 1.15 (although we have oil in our tank from 3 years ago which was about 68c litre then) so in four weeks we have used about 118 euro worth of oil.
When we first moved here 18 years ago I installed oil central heating, oil at that time was 16 Irish pence a litre. I ripped it all out about 6 years ago and sold the oil fired Rayburn for nearly what I paid for it (nice!) and not regretted it at all.
All the windows have now been replaced and 4 years ago I had cavity insulation and loft insulated courtesy of SEI.
The thing that works really well here is night storage radiators, although I know a lot of people hate them. We have a large one in the hall/passage that links all the rooms, one in this computer room and a small one in the bathroom. All of them are fixed to inside walls and more or less heat the structure of the house as well as the air.
In the sitting room there is just a small woodburner which in really cold weather also burns ecobrite, but at other times burns our own wood but is usually only lit for a couple of hours at most and then allowed to go out and it stays warm for the rest of the evening. To be fair, the storage rads do the work as the whole house never drops below 18 degrees.
Do some research on storage radiators, our last year's ESB bill for night heating was €507 from September 2011 to May 2012 and for probably 6 bags of Ecobrite @ €17.00 per 40Kg bag makes our monthly heating bill about €73.00.
(Night heating rate with Airtricity is 8.41c per unit (just gone up from 8.04))
Edit; If you do research this, make sure you specify "Night Storage Heating" and NOT "off peak". Off peak has a separate standing charge where NSH has no extra charge.
