1)Th...A few points of note when doing a comparison:<br />1)The moisture content of the pellets varies a lot and if left for any time will reabsorp moisture up to 20%, I think the calorific value as advertised is around 17.5%.<br />2)The boiler efficiency quoted must be based on the lower calorific value as I doubt if you could get efficiencies over 90% for pellets.<br />3)The added labour involved in removing ash (>15%)and disposing of same has to be considered, and maintenance costs are higher. <br />3)Pellets are not a runner at all with natural gas comparison.<br />Jimmy Nolan EESThe Patsy Edgershttps://www.blogger.com/profile/02056194176493123736noreply@blogger.comtag:blogger.com,1999:blog-29370135.post-60068553568221409292008-03-21T22:18:00.000+00:002008-03-21T22:18:00.000+00:00Just found your blog and interesting comparison. ...Just found your blog and interesting comparison. I am presently considering a wood burning (gasification) boiler due to horrendous oil bills. Have to decide soon as apparently the grants end (here in N Ireland) on 31st March?? At least I have some woodland and could also plant willow for ongoing supplies I hope.<BR/><BR/>Consider also the extra heat losses associated with a 1500 - 2000 litre hot water accumulator tank and the extra pipeworks, pumps etc<BR/><BR/>AidanUnknownhttps://www.blogger.com/profile/10240941408506579139noreply@blogger.com
