Wood Pellet Boilers
The fireplace guy came to see us this morning to size up the job of installing a wood burner. Whilst he was here we got talking about what we would do in the future with the central heating and he raised the idea of a wood pellet burner. I have read about these before and thought they were a good idea but assumed that they must be either illegal or taxed heavily in Denmark. It turns out that they are neither and may actually be a good idea for us as a replacement to using oil and cheaper to connect to and run than the local heating.
The impact of that would be repairing and re-lining the chimney on top of all the work involved in changing the heating system. However, that will be cheaper than connecting to the local heating and apparently the cost of the a KW worth of wood pellets is about half the price of the equivalent amount of oil. Now we need some estimates before we decide which way to go because it affects how we will connect the fireplace to the chimney if we want to go down this route.

As I was saying......
ReplyDeleteI have a multifuel stove for smokeless zones and make newspaper briquettes which to date have not given out the 12KW of heat that the makers of the stove say is possible.I think I would need an offshoot from a local colliery and a train of coal per month for that output. Would only need a small turbine and I could start supplying the neighbourhood with power.
ReplyDeleteThe parkray burner at the old house had a gravity feed which would keep burning anthracite slowly for the whole day while you were out with no stoking. aj
I work on 4 1200MW heat output boilers. We can burn up to 5% by weight of wood pellets. The only thing that I would have a concern about is that the pellets can start to compost and smell after a while and if damp, they can also freeze in the winter.

We are investigating still but it looks like a good, economical and reasonably environmentally friendly solution.
ReplyDeleteWe have space to store the pellets and don't have to buy years worth at a time so that should be OK.
This is nothing like a log burner, it is more like a high tech oil burner which happens to use wood pellets instead of oil. Apparently the hopper can hold a weeks worth of pellets and the ash, which is collected in sealed containers only needs to be cleared out "infrequently" whatever that may mean.
L&N bought one of these last autumn - based on their experience sounds like a good idea to check noise levels (also resonance noise in tubes) and capacity (they had problems heating the house and getting the water warm enough this winter).
