An Important Decision

The heating system is one of the most important parts of the home. Your choice of
a heating system will affect your family’s comfort and even its health for many years to come

25 Years of Experience and Service

In 1979, when Radiantec first started to offer radiant heating services, there were only two or three companies to choose from.

But now, you have many choices. It seems that new companies are coming (and going) almost every day. There are many reasons why Radiantec is still the best choice.

  • RADIANTEC has done tens of thousands of radiant heating jobs.
  • We have done residential, commercial, industrial and agricultural projects.
  • We have done heating cooling, and snow melting projects.
  • We have put tubing in floors, ceilings, walls and driveways.
"As a last minute discussion to install radiant heat in my slab, you folks were so helpful. I couldn't believe I spoke to a technician and the materials were shipped the same day." -Lars, AZ

CAUTION - 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.
