For Infrared thermal pictures of a dry bottom vft see my post on the following link ..
I assume dry bottom vft is the same as dry wall VFT is the same as dry leg vft?

I feel that my dry-bottom ross bendixen boiler was just radiating away heat - admittedly it had no insulation.
The wet leg vft on Nyitra is much more powerful and stable - but is also comparatively larger. The dry vft being 16" diameter, and Nyitra's boiler is 18" on the barrel and 24" at the firebox. VFT FTW in my book, but I prefer wet legs, especially manning-style vfts.
