I read somewhere a fairly convincing argument that ceiling mounted infrared heating panels was one of the best ways to heat a small boat such as a narrow boat with electric . Bearing in mind the headroom is always limited it would need to be built into the original design of the boat. They do seem interesting. Not cheap but still interesting.. The other thing I like the idea of is those old school electric fires. Probably not enough room but some of them are quite visually appealing. Random Google image search

............ a candle in the kitchen sink overnight helps to take the chill from the kitchen ................... oh dear - heat a big cold steel box enclosure with a candle.
someone has really lost the plot, innit?
(if in doubt, do the maths - calorific value of wax, rate of burn, etc.)

Burning four candles might work.

You think I'm stupid, but I have held my hand over a nite-lite (burns for 8 hours) candle in a metal and glass lantern and it produces a lot of heat, so much so that you can't hold your hand close. That heat has got to go somewhere, hasn't it? And as the candle is in the kitchen that means the air in the kitchen will be warmer in the morning after having the candle burn for, say, 7 hours between 11pm and 6am, especially in still conditions with little wind. The stove in the bedroom does send heat to the kitchen, of course, that's the main reason why the kitchen isn't freezing, but the candle must raise the temperature by a degree or two. If nothing else, it makes me happy, and gives the kitchen spiders light to read by.

as I said, compare calorific value and burn rate to establish the watt rating of a candle and compare it with the watts you get off an electric or other heater.
PS : yes I do think you're stoopid

It's a candle, not a 2 kilowatt fan heater. Gawd. And I was joking about the spiders reading.

I've seen those in a shop, by the way. Yes, I did get it. And it's Goodnight from me, and it's Goodnight from him. In fact I got the idea from some boaters we met who said that whenever they arrived at their boat and it was cold, they put some candles on and it soon warmed up. My one (or two) candles in the sink (to prevent fire if they fell over, which is 99.99% unlikely anyway) is enough to keep me warmly smug if nothing else.

Whilst 1 candle doesn't make a big difference, I must admit, that if I've let the fire get a bit low of an evening, if I light the 6 tea-light holders on and 2 church candles either side of the telly but you can feel a difference within a few minutes... I suppose, if a tealight gives out circa 45 watts and a "proper candle" circa 80, I'm putting a little short of .5kw of instant heat into the cabin.... that's like one bar of my old halogen heater on.
When they set fire to the boat, obviously it'll be a LOT hotter !

Love t lights, and in stable holders they're safe. I'm sure I wouldn't want them to be my only heat source, but they certainly do add warmth ... naked flame, why wouldn't they. But I just like the subdued, flickering light ... you'd understand if you saw me Rog

You could watch the fan rotate and when it stops you know the candles have gone out.
That's what they are for.
I've never had candles on any of my boats as I perceive them to be a fire hazard.

I'd rather be snugly warm than warmly smug anyday. What about the Particulates released into your lungs. Them little candles put out as much as a badly tuned bolinder.

The cleverest boat heating system I ever saw was a metal box with a door and some sort of drainpipe leading out of the cabin top.
The person had thrown newspapers and wood in and ignited it with matches. The smoke was lead out of the vessel by the drainpipe. Clever.
It'll never catch on though.

Random Google image search Don't poke at the glowing red wires with your mum's knitting needle. The results are shocking. Plus you then have to hook the two coily ends of popped wire back together so no one knows what you've been up to. Don't ask how I know this.
