Floor Warming and Room Heating - Indoor Applications

What Is Electric Radiant Heating?

Radiant heat is similar to the energy of the sun! We all know the warmth of basking in the glow of direct sunlight on a cool day. Thermostatically controlled radiant heating works the same way. Radiant heating warms people, pets, floors, furniture and all other items in the room. The heat of convection from these objects warms the surrounding air, providing the cozy comfort your home deserves.

"Hot air" rises but "heat" can travel in any direction. Radiant energy transfer is caused by a warm surface giving up its heat to a cooler surface. The air in a radiant heated room is the same temperature as the room, because it is not overheated in the way a baseboard, furnace or radiator heats, it doesn't rise to the ceiling at the same rate. This reduces heat loss and makes the room comfortable with a consistent temperature everywhere.

Without radiant heat you are missing out on a truly comfortable living environment in your home or business. By controlling both the air temperature and the radiant transfer of heat to nearby objects, radiant systems deliver a comfort that is unsurpassed. Radiant floors and radiant panels are ideal sources of this type of heat. The larger the surface, the lower the actual surface temperature required. A wall radiator may have a surface temperature of 180F, while an 81F heated floor will provide the same heat.

Whenever there is a temperature difference between two surfaces, both surfaces will attempt to equalize. Radiant energy travels through space without heating the space itself. It only turns into heat when it contacts a cooler surface. Our human comfort relies just as much on radiant heat transfer as it does on air temperature, yet the majority of heating and air conditioning professionals think only in terms of air temperature.

With radiant heat, the room and every object in it become radiators. Typically, the temperature in a radiantly heated space matches your skin's temperature thus eliminating heat loss from your body. Because of this, the room actually feels warmer, even though the actual air temperature may be cooler. As a result, radiant heat offers unparalleled comfort and decreased energy bills!

Difference between Floor Warming and Room Heating

The general working principle introduced above applies to both floor warming and room heating applications. The difference between a floor warming system and a room heating system is determined by the thermostat being used.

A floor warming thermostat has one remote sensor installed in the floor. By measuring and adjusting the "in-slab" temperature, it keeps the floor surface warm for bare-feet comfort without necessarily heating up the air in that room.

A room heating thermostat is generally used when radiant heating systems are installed as the primary heat source. All room heating thermostats come with two temperature sensors: one remote sensor measuring "in-slab" temperature and one built-in sensor monitoring ambient room temperature. The combination of these two sensors will make sure the room temperature is maintained at a desired level while the floor is neither too warm nor too cold to walk on. Minimum & Maximum floor temperatures can be set for optimum efficiency and comfort.
