I had been looking at gasifying boiler (Attack DP35, Atmos D35GS, etc.), but non-gasifying ones are much cheaper, and seem comparable in terms of efficiency (for example, 83% vs 84%).
There's even one (the PER-EKO KSD 22/28 kW from the Kotly web-site) which claims 93% efficiency - well beyond the claims for gasifying boilers.
So I'm a little baffled as to why anyone would choose a gasifying one, and I'd welcome any input..

Hi David I understand that gasifying boilers reach higher temperatures than non-gasifyers. While efficiency may not be the issue as you suggest, with batch boilers speed can be important and it may be in this respect that gasifying boilers score over non-gasifyers.

Ah, right, thank you.

No problem. I am sure there are other differences besides. I am surprised Winterbourne hasn't popped up to plug his company again and deliver us another infomercial into the bargain.

Something Mr Winterbourne has pointed out to me in an e-mail is the likelihood of obtaining a Government Grant under the Renewable Heating Initiative.
It appears that an installation by an MCS certified engineer will qualify me for £750 pa for 15 years.
This seems like a lot, and since it also requires that MCS certified equipment is used, which, in practice, means a gasifying boiler, presents a strong argument for using one.
Anyone know whether those figures are right, they seem... excessive.

Ask the advertiser how much he has already received from these moneys.....
You'right, for this money the average home could be heated twice.

Please see http://www.decc.gov.uk/en/content/cms/consultations/rhi/rhi.aspx Print off the consultation document 'Consultation on the proposed RHI financial support scheme' 9.0p per kWH up to 45kW 6.5p per kWH above 45kW Subject to MCS approved product installed by an MCS approved installer. Although only 70% set in stone it will invariably copy the feed in tariffs in existence from April 2010 for renewable power and will be clarified October 2010. Can be claimed for biomass boilers installed from July 2009. Potential customers may wish to speak to the DECC e-mail rfi@decc.gsi.gov.uk Please feel free to check my excessive claims. Hope this infomercial proves useful.
