Not sure if this is the right group, but here goes...
I have a small Morso Squirrel multi-fuel stove, burning mainly anthracite
with some wood during the day. Over the winter, the stove has started to
use more fuel - approx 50% up on the previous winter. All the bricks are in
place and the rope seals are in good order. The bottom grate (that you
shake the ash with) was replaced last autumn. I suspect that the stove is
drawing in too much air when at idle. The air inlet was always set at about
1/8 to 1/4 of a turn from fully closed, probably 90% of the time, and this
gave good heat, plenty of hot water, and good fuel economy. Now I find I
can run the stove with the air inlet fully closed and it runs fine (before,
this would have made it go out after a few hours).
So, too much air getting in? The culprit would seem to be the hole where
the rod that activates the grate shaker passes through the outer casing. It
has gone from being a tight sliding fit when new (~10 years ago) to an
irregular hole about 2-3mm wider than the rod. I reckon that extra air is
getting in here and wrecking the air balance. Two questions -
1. Does this sound like the problem, or does anyone with experience of these
stoves have a better explanation?
2. What would be the best way to mend the hole so that it is once again a
snug fit around the rod? The casing is cast iron. I've used JB Weld
successfully before on boats and cars to build metal back up, but I don't
know how to prevent it just gluing the rod in place as it sets.
If anyone knows of a better newsgroup or website for this kind of
discussion, I'd be grateful to know about it.
Thanks in advance.
