Hi there,
Also in SW Ireland. Did a major renovation to an old farmhouse with extension last year. The old house was wrapped in insulation, new roof, floors etc. The extension is new build. Have a bit of forestry ( Ask, Oak, larch and Spruce) so went for an ECOANGUS 40kW log boiler with 3000L tank linked to UFH. Overall, I'm happy with it. The house is as warm as my wife likes it ( very hot!) and plenty of hot water. I too have a large old stone shed adjacent to the house as a wood store. The shed is very handy as cleaning out ash and the odd bit of smoke etc when reloading isn't a problem. Cats not mad about it though!
Be advised, it has used A LOT of wood since we moved in last Oct. It is a lot of work to cut, dry, and stack enough wood for it ( maybe for the next 15 years hopefully!). The boiler suits somebody at home at lot of the time ( farmer etc) as plenty of checking when lighting / loading required. During cold spells, I will light it every day, every second day currently. I batch burn very dry ash from thinnings in 500mm lengths and it seems to suit it well. I'm going to try spruce/ash mix next winter.
Installation was a problem. Got rid of first guy. Then found a polish plumber who was familiar with them ( it is really a rebadged polish Orlan boiler) . ECOANGUS support from UK is excellent. Sometimes I wish I had fitted a heat pump for the ease of turning on a switch but when I get my electric bill, I change my mind. Don't forget there is a cost associated with felling, splitting, loading and transporting your timber to the shed even if you do it yourself ( diesel for tractor, petrol and oil for saws, logsplitter etc.. it adds up!) but for me, it is a cheap way to have a very warm house IF YOU HAVE YOUR OWN SUPPLY OF WOOD !!!! Otherwise, it is crazy without RHI.
Any other questions, give me a shout !
