I keep the fire in on the barge 24/7 all winter using Brazier smokeless. Lots of leftover binder and filler (it's not ash!) but it does the job at the end of the day.
I like it because it is supplied in the 10kg bags which are a godsend. And not expensive. I had reason to lift a 25kg bag the other day for my friend and I have no intention of using that size of bag again on my boats. Ok it means road based delivery which is a bit technical in some situations but 10kg bags are amazing.
I specially like the 10kg bags. They are really good.
Talking of carbon, I have just drilled one hole in each of four scrubbing brushes. A screw goes through the hole and into our barge pole so I can stick that down the chimney and give the inside surface a rub-a-dub-dub. One for Christmas, three spares. Kitchen towel in the grate to catch whatever falls off.
Why worry about 'carbon footprints'? What are we 'saving the planet' for?
Quiet minds cannot be perplexed or frightened but go on in fortune or misfortune at their own private pace, like a clock during a thunderstorm.
I hope that I never become famous and someone trawls my contributions on this site looking for the odd post which may be offensive.
Having said that if you look at the diagram then once you extend in order to place the weight somewhere else like on top of a boat for example the 10kg starts to look a lot more sensible
Depending on the height of the bank it is fairly likely the top of the boat will be between elbow and shoulder height for a normal canal boat on a normal canal. In which case my 12.75kg estimate of ideal weight works quite nicely for a man lifting.
