What Is Radiant Heat?

he simplest source of radiant heat is the sun, which heats bodies and things. These in turn re-radiate heat into the air around them forming a protective envelope. Unlike forced air or convection systems, radiant heat does not directly warm the air. Since it is warmed air that rises, the heat from a radiant source does not stratify, leaving the floors cold.

In addition to the sun, radiant heat can be produced by heated water (hydronic) or electricity. Summitteers Radiant Heat specializes in electric radiant heat. If you are looking for hydronic heat, contact the Radiant Panel Association at 970-613-0100 or by e-mail: misc@rpa-info.com

Our product line includes mats, wires, cables, aluminized ceiling panels and thin-film products for installation on or under subfloor; in mortar, concrete or other thermal mass, as well as thin-film and panelized units behind or on the ceiling.

Why so many products? So that we can help contractors choose the best one for the particular situation. The site may have restrictions which eliminate a product. The size or shape of the space may affect the product choice. Price is sometimes a factor. Ease of installation is important. Contractors want their clients to get the best solution for their situation at the least total cost and in the shortest time.

Radiant Heat is considered to be more efficient than systems that warm the air or rely on convection--fan heaters and baseboards. In fact the California Energy Commission has rated radiant efficiency at 1.04.

Why Electric?

Electric radiant products are especially suited to remodeling situations--single rooms, areas where gas heaters are not permitted, where gas is not available, and especially as auxiliary warmth in tile or stone floors. Electric systems are hardwired into regular house wiring following the manufacturer's instructions. In contrast, hydronic systems require tubing to transport liquid, a heat generator (water heater or boiler), possibly transfer plates and considerable engineering. A hydronic system may also require a thermal mass such as lightweight concrete.

What Do They Have in Common?

Both electric and hydronic radiant heating systems provide comfort, cleanliness and are dust free.
