[RE-wrenches] Forced air Furnace

[Drake]

Dana,

Your comments, and other comments on this list have made me see the 
light. We are going to go with a boiler.

What is the best source of equipment for this application these days?

Many years ago, I helped install a system in Colorado using El Sid 
pumps, with guidance from you, if you recall this ancient history.

Cheers,

Drake
