One thing my degree in electrical and electronic engineering taught me was that if you take the live-aboard positives, and the live-aboard negatives, and connect them together, there is a horrible flashy thing and smell of burning.

That'll be my fire when I get it going in the morning with an eggcupful of petrol.

I have been working on a design for remote lighting of the fire involving wrapping nichrome wire around a swan vestas match and a GSM cell network operated relay system feeding 12vdc to the wire. It does sort of work when done manually.
The problem is that the swan vestas matches are not nearly as good these days. Much less pink stuff on the end and they barely ignite the wood.
I think it would be necessary to scrape the stuff off and compress it into a small ball somehow with the nichrome wire embedded into it.
Did wonder about using glow plugs but not sure if they would successfully set fire to the tinder.
Petrol is not ideal for this. Diesel or even better olive oil but one needs a bit of heat.
Maybe a glow plug and olive oil.
Nice thing about a glow plug is one could drill and tap the stove and screw the thing in so it would be very tidy.
How to convert the glow plug end into a flame. Maybe wrap a load of swan vestas matches around it. Repeatability would be an issue.

Why not just light the fire like everybody else?

Why not just light the fire like everybody else? The idea was to be able to get it going remotely. |

The idea was to be able to get it going remotely. Why? For a situation where you have no other heating, you have not been on the boat for a while, the fire had gone out and it seemed like a nice idea to arrive at the boat and find it warm. A winter thing not that useful in summer time. I think it would be quite a nice option for a boat which takes a while to warm up and does not have an oil burner. You would have to get the timing right and put the right amount of kindling on it before leaving the boat. Ah. I see a flaw in my first sentence.. Oops |

Nichrome wire wrapped around a swan vestas match then fed 12v will start a fire.
The other thing is those model rocket igniters. Basically the same thing but already made.
Only problem I can see is the fire would have neeeded to go out completely before setting it up.
This would be fairly awkward to sort out if the fire is the only heating.
Lighting a fire remotely using mobile phones and GSM gate openers is not at all difficult.

How do you adjust airflow remotely? I suppose it could be done with an ash door closing mechanism and a timer, although I'm not sure such a mechanism would be trustworthy .
To ease the actual lighting, why not install a gas poker? (Used to be common in the days houses were heated with coal fires)
Taking it one stage further, perhaps some sort of heater using gas or diesel as fuel would be easier to control. Oh ....

It was just an idea to get the fire going a bit before arrival at the boat.
Basically just pile kindling and a certain number of briquettes on it. Then send the message to the gate opener at the right time.
Probably not all that practical at the end of the day but still interesting.
Diesel forced combustion heaters are child's play to get remotely operated. The coal fire seems a more interesting challenge but also futile.
