Probably. But 20 minutes under load should warm it up. If the heater
is mounted above the engine, its possible to get an air bubble that
blocks the flow.

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.

yeah but ya love the smell, right?

usually run for 10 minutes and that's mostly to charge the
batteries some.

Be sure you have a galvanic isolator, or isolation transformer
or that aluminum tank won't last.

What's with all the html?

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

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.

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

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.

Yep, not a lot of effort went into the insulation.
