condenser with more surface area

[RumBull]

I have built a new condenser where the water runs both down the center and around the outside. I know they have been built before, but wanted to show how I tackled the problem. My previous condenser was a 1/2" pipe with a 3/4" water jacket.

It is made with 1/2" center water cooling pipe, 3/4" steam path pipe, and 1" outer water cooling pipe.
The volume of of the steam path between the 1/2" and 3/4" is about the same as the volume of a 1/2" pipe. The benefit is in that it has nearly 3 times the amount of copper surface area to condense on. As we learned on the parent site, double the surface area, double the cooling, tripple the surface area and tripple the cooling!
