I was asked wheather or not a 7000 btu Weabasto heater would be too much for a CD-22, making it cycle on and off constantly, which is both bothersome and hard on the heater. Here's the response I gave:

The 7000 btu isn't all that large. My Force 10 Cozy Cabin heater puts out 3000 on low and 6000 on high, and I think the Dickinson Propane Fireplace is 4500 and 9000. The average gas stove cooktop burner is 6000, and the larger burners are 7500.

I don't really have any formulas/knowledge of the btu/sq ft or cu. ft ratios.

I did stay in my 26.5 ft Sea Ray last night (first time), though, and the amount insulation in that boat is so great that the larger boat takes only abut half as much heat as my CD-22!

I'm guessing that the Webasto 7000 unit is their smallest, and it doesn't sound like all that much heat, comparatively.

One way to tell is to use an electric heater at the dock on shore power.

On the High setting of 1600 watts, the electric heater is putting out about 6000 btus. On Low, it puts out 800 watts, about 3000 btu's.

If you put the electric unit on High, it should cycle on and off just about as much as the Webasto would.

If the cycling on High is too frerquent, or If you have to turn it down on Low to get it to work reasonably, then the Webasto has too much output to control reasonably.

As a guide, I use an electric heater at the dock here at Lake Shasta, and it can be left on Low all night and runs continuously with temperatures in the mid to upper 40's.

W/O a generator, you won't be able to match the wind chill underway, but a windy night would work just fine.

Hope this helps!

Joe.

After reading all the posts about Wallas's over the years I'm convinced they made good ones and bad ones. Lucky me!

I'm not sure about the various formulas for heat btus vs cu ft of space to be heated vs r index of insulation, etc. Smile

but I will say that my Webasto, their smallest, heats my 22' so quickly that my wife and I find ourselves turning it off after just a few minutes during a day cruise. Overnight at temps above freezing, (40's) I set the thermostat for about 57-58 and the Webasto cycles on occasionally to maintain that temp. It does produce a ticking sound as it operates and I'm told that is the fuel being injected into the burner. It is a rhythmic sound and does not bother us. Some might find it annoying. The blower also makes some noise but I am quite willing to ignore that as the forced warm air comes out of the ducts.

Bear in mind that our Webasto experience is just this year. Who knows, they may have a self-destruct feature built in to activate on the day the warranty expires.

Here's a small Wallas for $1200 instead of $2100 or more:

Of further note:

The Webasto Airtop 2000 has a High and Low setting that is 7,000 btu's to 3,100 btu's*, just like most of the smaller heaters used in the C-Dory!!!

Look: LINK

* equivalent to 2,000 and 900 watts, respectively.

HERE"S that Webasto listing on ebay.

Last count: 1075 British Pounds Sterling or $2011.54 (3:30 am, Sunday, Oct. 8, 2006).

On Edit: I first thought the 1075 was U.S. $, but upon closer examination it's BPS (don't know where to get the fancy "L" from for their money symbol.)

THIS IS A "BUY IT NOW PRICE", AND THERE ARE TWO AVAILABLE, SO YOU CAN HAVE ONE FOR THIS PRICE! (UNLESS YOU WANT BOTH OF THEM!}

Please not the change in the price in the above post:

Last count: 1075 British Pounds Sterling or $2011.54 (3:30 am, Sunday, Oct. 8, 2006).

On Edit: I first thought the 1075 was U.S. $, but upon closer examination it's BPS (don't know where to get the fancy "L" from for their money symbol.)

So the $1200 deal on Craig's List is just under 60% of this and looks better all the time!
