Gasification boilers

dande

I'm currently looking at renovating and extending an old cottage. I'm looking at alternative heating to oil. I've just come across wood gasification boilers. Can anybody advise me on what they are like. Who can people recommend to buy from. Waht heating system are you feeding off the boiler. Rads or underfloor. Underfloor is out really for me as I would have to rip out all the existing floors.

Does the wood need to be seasoned. I have access to a forest where I can buy wood at a good price.

Any advise wood be great.

yes it does need to be seasoned. the recommend having wood with a moisture content of 20% or less to run at there rated efficient

I have a 42 kw log gasifcation log boiler .
Yes there brillant , but in saying that they must suit your lifestlye . As there is some physicall work in it each year . Plus i load it in the morning and evening about 7 or 8 logs a day . I have ufh and rads upstairs and the sq of the house is 2600 . I have no heating bills and a constant tank of hot water . I have my own free supply of timber .
You will have to purchase the choped and splited logs they must be the lenght of the boiler mine that 600mm logs , smaller logs are not really suitable as they just burn out quickly . Depending om the sqf of the house and the termal qualtiy of the insultation of the house you will use any thing from 15m3 to 20m2 hardwood .
Its a big step to take and its not all roses , i have mine a few years now and i have been through the mill with it with small problems . Be preprared to get your hand dirty as the boiler needs to be clean once every month and the flue brushed clean 3 to 5 times a years as there can be build up of black tar this happens with some pine timber . The moister content in my opion would want to be near 14 or 15 percent as the 20 percent give off to much tar . Its a very hard balancing act to get it right .
Dont get me wrong i think there fanastic and i how have a free heating system , but it need minding and you cant let the boiler tank down over a few days or else you will be burning more timber to get the right heat .
I cut my own timber with a chain saw , split it , stack it in a outside shed for 12 months and than move it into the boiler house to more or less kiln dry it . Theres a lot of hand balling involed .

Happy burning .

I've just come across these as well and would like to hear from others. Are they generally kept outside the house, e.g. in a garage? Do you need a chimney or can you construct a flue when installing?

on a garage you can generally
