Which brand of biomass boiler is best?

Posted by Cathy Debenham on 6 January 2014 at 9:52 am

Q: We are going to put in a log gasification biomass boiler, and while there seem to be many companies out there that can do the job, none of them can provide us with unbiased advice on what is the best boiler. They have one brand /manufacturer that they deal with and proceed to slate any others I happen to mention. Are you able to help?

A: This is a really difficult question, as there isn't any independent comparative testing of boiler performance - just the product testing for approval for use in the UK (see the HETAS Guide to approvals) and MCS accreditation (which is vital if you want to claim the renewable heat incentive).

The main way of making a judgement is to ask the installers why they chose to go with the manufacturer that they do. If they struggle to answer this question, or it's all about price, then I'd discount them. You want a manufacturer that has good service standards, good reliability and a good warranty.

There is a blog answering this same question, but for solar panels, which has some suggestions that are just as relevant to other technologies - particularly the questions to ask installers. You can read it here.

Good luck choosing, and do let us know how you got on.

Hi Rachel

I'm not familiar with it personally, but there are several Ekoheat products that are accredited by MCS, so if you did choose one you would be eligible for the renewable heat incentive.

Hi, my installer is pushing me to install an ekoheat which I've never heard of. Does anyone have any experience/comments on the brand?

@HighWinds I've put out a call on Twitter to see if anyone can help.

Has any one has a Nordica Extraflame Biomass boiler installed?

Would welcome any comments we are planning a 20kw with a 300 litre DHW cylinder and 300 Litre Buffer cylinder.

Wow. An insightful and difficult question. I would take slight issue with your comparison with Solar PV where the differences between panels is less significant. In biomass quality really is king, but then you'll pay for it. Cheaper boilers lack the finesse (efficiency) and quality (lifespan) of more expensive systems, and although they may cost half the amount , the combination of low efficiency and short lifespan will reflect this. When buying quality, it is akin to buying an Audi or a BMW. Both excellent cars and well engineered, but with slightly different nuances. Perhaps the person posing the question might ask the same question about gas or oil boilers. This is also unlikely to have a clear answer. Carl Benfield
