Looking At Small Boat Heater Options & Installing a Dickinson Diesel Sig 100

We look over pros and cons of several heater options for a small boat and where best to place one. Then we'll install a Dickinson Sig 100 Diesel Heater and install a small feeder tank.

Very good...Dickinson recommends an overflow tank properly vented to the outside...where did you put that? I have found that when I sail and the boat is healed over some of the diesel slops out from the top of the flow metering valve and would spill into the boat without the overflow tank and the copper line from the flow metering valve back down to the overflow tank. Over the last three years that I have put in my Dickinson Diesel Heater the overflow tank has accumulated about a quart of diesel. I suck out that quart of diesel from the overflow tank with my hand vacuum pump...the same pump that I suck oil out of my Diesel engine when I do oil changes. Dickinson also recommends that you also vent the gravity day tank to the outside to allow for expansion of the diesel fuel and vapors that occur. You might want to go to Dickinson Diesel Heater best install ever...best SV Aquila...Seattle.

Thanks very much- great comments! I did attach an overflow bottle to the overflow fitting on the metering valve and I'll be showing that in the follow up video to this. I am wondering how you got so much overflow oil. Is it just from the metering valve itself or from upstream of that too? I agree about the gravity tank. I have not had the boat out on the water since I've hooked up fuel to the heater. I do not have it vented....yet. Not sure what I'll do. Maybe I'll extend an 1/8" line up to the exhaust hose for my composting head.

When the boat is sailing and heeled over some diesel spills over as the top of the metering valve has space...in other words there a space where the diesel will shosh out of the metering valve and either go into your boat or into the overflow tank if you have it properly plumbed .You also have to have both your supply tank and overflow tank properly vented to the outside otherwise you will get diesel smell in the boat.@@trailsandsails2722

Go to Dickinson Diesel Heater best install ever...I think you will see how and where I put in heavy duty black venting hose specifically for diesel...any other type of hosing may render your insurance null and void.@@trailsandsails2722
