PM's popular columnist John Siegenthaler gets numerous inquiries from readers seeking his help with thorny problems in the field of radiant heat. We have created the "Radiant Forum" as a special question-and-answer section to share with you some of the exchanges between John and his fans.
Our intent is to promote wide dissemination of ideas and technical information. Opinions expressed by either Siegenthaler or the correspondents about specific products and techniques are theirs alone, and should not be construed as a PM endorsement.
