Cabin heater finalized.

[Roger Long]

Thanks to all here who helped with comments. I think I finally have a plan for my cabin heat. You can see my web site page here if you aren't sick of hearing about it already.

When I think of all the 6 and 7 figure decisions I've made in my career on pretty much a "Hey, let's do it this way." basis, I feel kind of silly at how much agonizing goes into making decisions about my own boat. If I'd charged for all the time I spent on this, it would probably have paid for the system three times over.

It's been a complicated thing to figure out though. Having my existing hot water heater at the other end of the boat and too low for natural convection to make the cabin heater water loop work without the current draw and sound of a constantly running pump took some head scratching. I think I finally have a good solution that will also give me a bit of heat in the head. You can see it at the link.

how much weight will it add and are you concerned with it being off center?

He'll only do port tacks henceforth

Nope..he's gonna add a cooler and bar to the other side to counter the weight.

what did you use for your circulating pump? I have been worried about current draw from my 12volt system.
the loop I am working on includes the water heater, diesel stove and the engine loop. it will have 2 cabin heaters in the loop as well.
Just curious what kind of ratings on your pump as far as current draw and gpm.

if you want a pump, consider a pulsing 12 volt fish tank pump.

I don't think I'll need to counter the weight. The last time I watched two girls in bikinis move from one side of the boat to the other I didn't notice ANY change in the vessel's heel or performance. That's more weight moving a longer distance than this addition.

If you got two girls in bikinis. Why do you need a heater ?
