Diesel Heater Conversion.

[drbridge]

Our wallas diesel stove is 22 years old and still working, but not getting as hot as it used to. We only use it for heating and it never was the best heater. I am thinking about replacing it with a diesel parking heater. I am wondering what size people have been using in their C-Dorys. I am thinking the 2KW models would be enough heat for our C-dory 22 cruiser and easier to install than the bigger 5KW and 8KW units.

What size have others been installing in their C-Dorys and how have they worked for You?

Also, the thru hull fitting for the Wallas exhaust is the right size for these heaters and since it is already there would be convenient to use. Any reasons why I should or shouldn't use the existing thru hull.

Thanks

I use a 4KW heater in my uninsulated two car garage. When it is 40deg F out it can raise the inside temp to 60deg F. Since these heaters usually don't shut when they reach the set temp (just throttle down), I expect that a 4KW heater in a 22 is overkill. It might depend on where you do most of your boating though.
I am considering adding a 2KW heater to my 22, but I'm not sure how often I'd actually use it. Installing one would be a bit of a pain and may not be worth it for me.

I put a 5KW in my 22 cruiser and was happy with my choice. I don’t like to use things near there max setting, especially if there is fire danger and if confine (like in a boat), so the 5KW allowed me to keep it in low to medium setting most of the time. I do go out on the shoulder season when it will go bellow freezing often, your situation might be different. I did research that several year ago but if I remember correctly, the 5KW is more fuel efficient for the same heat output. Just a few things for you to look into/consider.
