SACRAMENTO, Calif. — According to the 4th edition of the Webster’s New World™ College Dictionary, “mild” is described as “not extreme in any way; moderate; temperate (a mild winter).”
Ken Barney gave his own interpretation of mild temperature climates as those that don’t vary over 20 to 30 degrees from overnight to daytime temperatures. A number of attendees at Barney’s seminar at the 2003 Annual Radiant Panel Association (RPA) Conference didn’t agree with those calculations. One audience member said that in his area in California, morning temperatures can be as low as 25 degrees while afternoon temperatures average 65 degrees. Regardless of the definition, Barney made some observations about installing radiant in “non-extreme” climates.
