On the issue of increasing the amount of heat being pulled off the stove...

Has anyone tried bolting a heat sink to the side of the stove under the jacket? It seems that greatly increasing the surface area of the stove under the heat jacket will greatly increase the heat transfer between the stove and the air.
**Broken Link(s) Removed**One of these heat sinks would add ~8 square feet of surface area to the stove.

My personal feeling is that you would get more out of the stove if you just put a fan blowing on the side.
Or put a fan on a corner so that it is blowing on a two of the surfaces..

I did this on my DVC-500 - I first bolted a freebie heatsink onto the side of the stove. Then I cut a hole in the side cover & mounted a nice ball bearing muffin fan blowing inwards onto the heat sink. I also migged the bottom of the stove side panel shut - so all the fan forced air would go across the heat sink & out the vents on the top of the panel.

Quite a bit more heat comes off the fan forced heat sinked side of the stove, fan only draws 12W - so instead of leaving well enough alone(the free solution) - I bought some ($$$) better heat sink material off of ebay - & did both sides of the stove. (gobbed that nasty white heat sink compound onto the HS & everthing else it was not supposed to go on) At this point I run one side w/ fan forced air & the other side via convection. The convection side puts off more heat (guessed by hand) than not having a heat sink. The fanned side definitely puts off volumes of hot air - was it worth it - who knows?

If you go the fan route - I found that most of the fans I tried sound good when bench run - but would make a lot of racket when mounted (fan whine and/ or motor rumble)
This is one of the main reasons I am not running both sides w/fans - it may wind up sounding more like a B52 than a stove. Also I have to agree with DLL, you may get almost the same effect by skipping the heat sink & just running a fan :roll: ...... I have some photos here somewhere -

I've already got the heat jacket and there's a 14 inch inline fan pulling air through it.

I think a heat sink make from aluminum is indeed a benefit although those close spaced thin ones don't have enough thermal mass holding ability to be efficiently functional as a means of extracting more usable BTU's .... as a example its great but I would make one of 3/16" or 1/4" thick aluminum spaced 1/4 to 3/8" apart and maybe even flute the pieces to provide more nooks for air flow to scrape off heat. like a custom snake fluted barrel from a hi-round per minute rifle barrel ????

seems to me aluminum is aluminum. you could mount aluminum T angles up the sides of the stove and get the same effect. that is my plan anyway.

If you look at the "pics of your stove" thread, someone did the Aluminum angles on the sides of the stove to extract more heat.
