pellet boilers
Can anyone advise on domestic pellet boilers? We need to replace our gas boiler and I am spending a lot of time trying to research wood chip and pellet boilers on-line. I have e-mailed a few hopeful people but had no reply. Maybe someone out there can help!!!

Re: pellet boilers
Hi Laura,
I looked into Pellet boilers when I replaced our old gas boiler, which failed on Boxing Day this year! These are my findings:
I think the idea is great especially as the wood chip fuel is effectively carbon neutral. Unfortunately like most things, economics come in to it and I found even though grants were available the cost would be 3 to 4 time more expensive. The other factors are:
- Where to source the wood chips, you need to be in a certain proximity for the delivery to be cost effective.
- Space, you need to have room for a hopper and delivery system to have a continuous feed to the boiler. The space I looked at was a small outbuilding 2m x 2m x 2m.
- Maintenance, depending on the boiler they need the ash clearing and the desooting at specific intervals.
In the end I went for a condensing boiler and fitted a unvented hot water cylinder with twin coils for solar water heating. I am looking into the collectors at the moment, so if anyone out there has any recommendations, that would be great. I am pleased with the gas boiler, it seams a lot more economical than the old one.
I have some info on wood pellet burners if you want more info.
Thanks for organising the first forum - great job and to Phil for setting up this great forum.
Regards
Simon

Re: pellet boilers
Thank you Simon for responding. Sorry to have taken so long to reply. After a quote for £3000 for new gas boiler due to old radiator system we are going back to square one and looking again at pellet boilers but all the comments you made we are familiar with as things we came up against. Very tricky but somehow I feel savings must be spent in this area and not on a holiday or some such frivolity!!!! It means a lot of savings though!!!! Perhaps if you come along to the next meeting you could bring any info you have as it may complement ours. Cheers.

My note of the SEV conf FC man's talk says £6000 for the smallest CHP woodchip boiler.

I would recommend rural energy as a local(ish) company who are pretty honest and ethical (no I don't work for them!) http://www.ruralenergy.co.uk/

Re: pellet boilers
Thank you people. Went to Robeys (the wood stove people) in Belper today and the man there was very helpful regarding the idea of boilers and explained why gas is still probably the best option. He made sense, linking in with Simon's comments above and suggested British Gas may well give a decent quote......so next step....another quote or two. It is all rather time-consuming!

Re: pellet boilers
Hi Laura,
As I noted before, the Worcester Greenstar condensing gas boiler is what I went for in the end. It is very efficient and I linked it to a very good quality copper unvented cylinder (this gives me mains presure, at the hot tap as well as the cold and we could then also remove the two header tanks in the loft). The cylinder has twin coils, one being heated by the gas boiler the second for solar. I ordered the solar panels this week, so that will be up an running soon. I know not the best time of year...
Good luck with your ventures

Re: pellet boilers
regarding condensing boilers, since April, all new boilers fitted have to be rated SEDBUK A or B for efficiency. All of the condensing boilers such as the Greenstar are A rated. However, you have to make sure they are properly sized, to get the efficiency improvement. If the boiler is too large for your house, it may not be operating in the condensing mode a lot of the time and then, then efficiency gains will be a lot less than the 10-12% often quoted.
regards,
Phil
