concerning the last post...

Just a thought, after you study the earlier post, if anyone has any ideas for a digitially programmable thermastat that would regulate (kick on or off) the pump when the water in the boiler reaches a certain temp, so that it doesn't pump cold water through a nice warm floor, I would be glad to hear of it. (cheap, of course, like something scavaged off of an old piece of equipment). And, by the way, the new pump is working great!
