I run a Morso 1410 at home and burn Anthracite and have tried over the last 8 years most solid fuels. One of the things I have found when riddling the stove dust etc is carried by the rising air etc up and onto the throat plate and that needs a quick cleaning once a month. I am wondering if the fuel you are using is slightly damp. If it is that could be the cause of the dust forming 'concrete' Important fuel is dry to get only easily brushable dust on the throat plate. Just a thought you say once light it never goes out until the end of the season. Suggest that it is let out once a week as the buildup of dust from the fuel need cleaning out Thanks for your help. Running a stove on land is different to running a stove on a boat. The reason being the length of the stove pipe. Unfortunately there's not a lot I can do about that. The same goes for the damp fuel. The fuel will be as dry or as wet as the weather is on the day it was bagged. We have had bags where I have had to cut the bottom corner to drain the excess water off. So there's not much I can do about either. As for letting it go out once a week - not a chance I'm afraid. The fact that I have to let it out once during the season is bad enough. I couldn't put up with that frosty reception, from the missus once a week. Having run Morso stoves both on NBs and at home there is less difference than you think, yep a house flue can have a better draft. I would suggest either clean it weekly or put up with having concrete on the throat plate and possibility of carbon monoxide poisoning as the flue route blocks up.

He's already said he only burns smokeless fuel not wood I read that and then for some reason completely ignored it. It does look like the stuff we used to get from burning parquet flooring as well, if you get the fire hot enough its what happens to the tar off the back. But as its smokeless I dont think there is a high tar content either. Being smokeless fuel it seems strange it leaves any sort of residue inside the stove other than ash. The parquet flooring is glued down with tar and asbestos!! the asbestos is an anti-slump agent very common and of course illegal to sell and burn!! In my former life I was an asbestos inspector you find the stuff everywhere a real pain.

My uncle worked for a firm that took this stuff up from schools and all sorts of places, we probably burnt it for 10 years in all regularly. The tar on the back gave off a smell I can only describe as pungent, now I know it was also possibly carcinogenic.... lovely.

Next season I will religiously clean it weekly and see how that works out. Shall report back next year and let you know how it worked out. In the meantime I have, when I've remembered, on occasion put the brush down there. When I pulled it back out it came out wet and sludgy. Any ideas as to what is going on there? Seems to me that there must be a cold spot, or something, down there.

Seems to me that there must be a cold spot, or something, down there. The wet stuff is probably a result of not burning your stove at a high enough temperature. It's a problem with 5kW stoves in boats. They produce way more heat than most people need, therefore they get turned down to simmer most of the time. That's the case with us anyway. We bought Morso's flue pipe temperature gauge and we're NEVER running it in the 'good' zone. We clean the stove about twice over the whole winter and a third at the end, with no problems yet.

I think there you have the making of your concrete ash dust and water in the flue, which will almost certainly run down the flue into the stove. I am assuming that the flue exit has good protection from the rain etc and is not just an open pipe. Agree with loafer the stove is being run too cool. Thus the moisture in the flue gases is condense out as it hits the cooler metal of the flue above the roof. I would suggest, if you have not got them already, that you get the Morso side cheeks (coal inserts www.elyboatchandlers.com/morso-squirrel-parts/morso-squirrel-coal-inserts-pair?source=Froogle) which allows you to burn a small hotter fire and open some windows and doors.

It is a problem to say the least when these floors were laid asbestos was in use everywhere and it was cheap and plentiful so of course it finds itself in all sorts of products remember the black garages corrugated tin sort they were galvestos coated horrible stuff and in the 60s everywhere!!

We had one of those next door to us, I told the owner about it being asbestos and needing proper disposal, next day he wrapped a tshirt round his face and went at it with a sledge. Had to ring Enviro health to stop him as the clouds of dust thrown up went everywhere. In the end a proper company came and tented the garage and did it properly.

I've just seen Bill Murray, of Ghostbusters, on TV. Blimey, he's gotten old and wrinkled!

I do not suffer from the 'concrete' buildup, but our stove does need cleaning a few times a season. I usually manage it while it is still lit... Allow fire to burn fairly low, then with big leather welding glove, reach in and remove throat place. Lay throat plate down on top of fire, close door, go outside and brushes down chimney (I used to remove chimney and just brush flue, but chimney has now fused itself to the collar, so I brush the lot). I then return inside, and carefully remove the throat plate, with pile of ash on. The rest of the ash can then be riddled through the fire. Sometimes needs a bit of kindling to get going again, but it's never cold!

Anyone had any experience of Boatman stoves? Currently got a Dowling "little devil" in, but it's a top loader and smokes like the devil when loading it. Boatman stoves are made in Manchester so I can go and get one direct, they've also improved the efficiency to 78% and it has an airways to keep the door clean.

The concrete type build up got so bad, we ended up having a new flu two years ago.
Our first 5/6 years onboard we experienced no problem. We only burn smokeless fuels.
Then 2/3 years ago we had the flu problem. Once removed, it looked like a 1" lining of concrete. A friend had the same problem, but he discovered his when the 'concrete' like lining, actually created a split in his flu.
I was advised that giving the fire a good blast of high temp burning, regularly would help. I was advised that burning all closed up, constantly, makes the problem worse. The deposits are in the fuels, it's whether they form into a lining.
I've taken to using the flu powder twice a week too. Don't know if it works, but when I last swept the flu I was able to remove all deposits.

I use Hotspot flue powder at home, the tar and soot crystallise and drop down onto the chimney plate, very little extra comes down when I sweep it.

That is, when I remember to use it. What brush do you use? I have a 5" nylon brush that screws onto chimney sweeps rods. I think it's working ok but time will tell. I haven't had to remove the throat plate so far this season and the stove still seems to be drawing fine.
