Scout,
Can you do me a favor - I have the 11 gal version of that, I'm guessing yours is the 6. Mine was installed before the deck went on, so to remove it, it would have to go through a small hatch. Can you give me the dimensions of the "box" and "cylinder" so that I can guess if I have to chop my cylinder (or deck) to get it out? The box is clearly too large, so I'd have to do some disassembly in place. Thanks, Jeff Scout wrote: In my basement. . .

No problem Jeff,
I'm on the road right now (again) to meetings tonight, tomorrow, and tomorrow night. First chance to get to it will be a bit later this week. But I will get those numbers for you. In the meantime, check out this page, might have the box sizes. http://www.seawardproducts.com/waterhtr.htm Scout "Jeff" wrote in message . ..

Scotty The hw heater element draws 1500 watts and my inverter is good for 1000 watts only. So at anchor I'd run the diesel if I really need hot water. I'm thinking of adding a fan coil unit for "free" heat when availble or so I can run the ac and the fan coil to dehumidify when it's really wet. Scout |

These lines are the hot engine coolant, not the cold and hot water lines. The important thing is it will work, just don't trust me to make the as-builts. Scout |

Scout,
A Sea Story:---- I had my Heater out and stored in the Pilothouse, to make room for the Shaft removal, to replace the "Thrust Bearing. I'd like to make the suggestion that you look at your engine/shaft coupling before you add to much to that heater. My heater was in the Port Side Cockpit Looker; forward against the cabin bulkhead. I had a 29 ft boat, but for a man to disconnect that coupling, next was necessary for a man to lay down on the floor of the cockpit to reach down to disconnect that coupling. Couldn't be done with the Heater in place. Look it over before your start modification. Good luck!! By the way; I tied off the engine's cooling water to the heater for my "Red Dot" heater which really was a blessing. http://community.webtv.net/tassail/ILLDRINKTOTHAT |

I'm not surprised at the stand-by losses of the Seaward hw heaters. There isn't much insulation there. Since I have it apart, I was toying with the idea of insulating the space between the tank and the sheet metal box with foam insulation. All of the working parts are on the front face of the tank, and I'd leave that with the fiberglass it came with. I might even put some rubatex insulation outside the box because I don't want to run the engine unless I have to. Hate the noise. Scout |

Be sure you have a galvanic isolator, or isolation transformer
or that aluminum tank won't last. What's with all the html? Scout wrote: In my basement. . . I'll clean it up and repipe it with a bypass and better service access (in March). http://sports.webshots.com/photo/291...97509592UoBucA Scout |

Jeff,
The dimensions of the galvanized box are 13" high x 13" wide x 16" long (deep). There are flanges welded to the tank which extend a further 1.75 inches on each end (bottom of tank) which make the overall length of the unit 19.5" The tank itself is about 14.5" long x 12" diameter. If you have an 11 gallon system, add 3" to each general dimension, making your unit 16" x 16" x 22.5" Hope this helps - Scout "Scout" wrote in message . ..

Thanks - this means my tank is 15 inches in diameter. Now I have to
measure the hatch - I think its a tad smaller. It also means that there's only half an inch of insulation.
