But, But honey. Everyone has LED bulbs in their nav lights!!

Because I had hail on my decks today and should be up north doing my winter job. I'm gearing up to finish the painting and varnish below decks this winter and also want to leave the berth and be warm.

Not sure I would trust one of those cheapies on a boat. After all, it is lighting a fire in a box in your boat. Hopefully the electronics are fail-safe, but how can you tell?
I have seen the Scandinavians with little wood heaters on board, carefully flued, and enclosed firebox. Using driftwood. No electronics! Just a simple little fan for heat transfer.

A cheapie is just a exact copy of a expensive model. My friends fitted one about 3 years ago and it's been trouble free. Proberly more safer than my electric fan heater I would say.

Good one, that should keep things toasty. There are quite a few people installing the cheapo versions down here in Tas. This is a facebook group that can help if you need any troubleshooting: www.facebook.com/groups/358361758340771/

I am not a fan of encouraging rip-off engineering. That said, it would be the electronics which would worry me. Good luck!

Most of the yacht designs we sail have been ripped from one design to another it's just how man evolves. The Chinese just have the man power and machinery to do it at half the cost. The electronics are not that combustible.

Thanks that's a great fb group. Initionaly I was going to mount it in the engine room but after some thought it's going in the spare quarter berth cabin (garage) up on the aft cockpit head floor with exuast to the transom and duct coming forward into cabin. The fuel is going to be plumbed direct into my main engine fuel line drawing from a 300 litre tank.

I originally had the fuel coming from my main tank but changed to the small, included, tank with an electric pump from my main tank to top up the heater tank when needed. It is only a tiny fuel pump & needs to push, not pull the fuel.

Have a look at the videos I mentioned above starting with number 16 - BEFORE you start!!

Yes the original idea was to fill the heater tank mounted In engine room with a pump from main fuel tank but the heater I ordered says it comes with optional pump to draw from a main tank. We will see when it arrives. I seen the videos . Do you mean video 16 ? Ok found it cheers. Awnsered one of my questions , how long can I run the heated duct , he ran his 8 meters.

I've heard that the fuel pumps are quite noisy, so you may want to consider where it's placed/insulated. That's the main reason I haven't gone down this path, both Misch and I are sensitive to background noises and something ticking away in the background would drive us nuts. I'd be interested in hearing about your experience with any running noise once you've got it going?

Just reading your last comment, do you mean that if you mount a day tank with enough head, then you can run them without the pump?

You still have to run the pump with the day/week tank but it is hidden away with the pump. Mine is tucked away at the transom & if you keep the fuel line off any structure it can't be heard in the living areas.

Be careful how you plumb it so that your boat engine fuel pump doesn't suck it out from your heater fuel line & draw air. If you run a separate line from the tank it should be OK.

Will put a T piece with fuel on and off cock. I'm hoping to put the tick pump in the insulated engine room and perhaps the 10 litre tank if I can get it drawing from the main diesel tank.

Sounds good. John, in the videos above, goes through the soundproofing of the pumps, heater unit and need for metal pipe through engine rooms in episode 16. Worth a watch.

My mate recalls it comes with a sillociin plate so no need for the rubber mounts we will see. I have spent 3 hours running a 6mm twin core wire from the switch board to the aft section where the heater willl be installed! Gotta love boats!

My new diesel cabin heater has arrived and is in the first stage of receiving a mounting frame! Ducting for the exuhast outlet and the heating duct for the cabin remains a pain but love boats so will get it done!

The little diesel furnace has power and is mounted in place,just waiting for exhaust piping ,transom outlet and 3 meters of ducting. Certainly been a learning cure but that's boats!

I installed one in my campervan. You must have a good CO detector, I bought one made in Ireland about $130.
Also ensure your exhaust pipe does not leak around where it fits to the bottom of heater.
At least in a campervan that all sits below the van floor on the outside, yours is inside the boat or under the floor

Yes it's just the exhaust run that's the big issue, just looking at heat proof silicon to support the hot pipe going out of the transom and through a bulk head wall. Will use the silicon and some some silicon tray cut outs to prevent fire from the hot pipe. I have also just ordered a 3 meter length of the flexible exhaust hose so there's not many joints upart from muffler and unit connection.

Maybe you should check with your insurance company about their fire clause and your disclosure obligations.

Why is not much difference than a one cylinder Diesel engine with a computer fan. If anything I should add this purchase to my comprehensive insurance as it actualy needs to my adjusted higher since my previous estimate since purchase of Icon.

Keep the exhaust run as short as possible & DO NOT have the supplied muffler inside.

Why


Why?? Because insurance companies are notorious for not paying claims if any technicalities are not quite right.

The heater is an addition to the boat and a source of ignition. Wouldn't hurt to tell them.

I am not argueing anything here. Just trying to inform you of a potential issue. It is your decision.
