Thanks for your help yesterday. The plumber and I added valves to the system and blew the air out. Our house (3600sq. ft. with 26 vaulted ceilings) heated up to a comfortable level in less than 12 hours. I went from disappointed to amazed.

Imitation is flattery; but sometimes it causes problems.
Radiantec is the original radiant heating company for the consumer.
Other companies have closely copied Radiantec,
but there are important differences in quality and support.
