Radiant Heat Flooring: The BasicsOctober 19th, 2010 | Posted by in Environment | Fuel Efficiency | Green Building | Green Homes | Green Products
Radiant heat flooring warms a room by allowing warming tubes just under the floor’s surface to send heat upwards from the floor itself. At this point, it’s one of the most energy-efficient ways to heat a building, standing far ahead of conventional forced-air central heating and radiators. In fact, it so efficient that it’s recommended by the Passive House Institute, which we wrote about recently here.
With traditional forced-air central heating, warm air is blown into the room and immediately rises to the ceiling—making for a lovely warm ceiling (which nobody needs), but cold floors. Radiant heat, on the other hand, takes advantage of heat’s natural tendency to rise, making the best use of its journey upward by starting at the lowest point in the room. This process is generally far more efficient than any other form of heating, heating the room faster, keeping it warm longer, and allowing the thermostat to be set to up to 8 degrees lower than usual to obtain the same level of warmth. This results in not only lower energy bills, but less fossil-fuel consumption to provide the power that most heating systems require.
An added benefit of radiant heat is that it doesn’t dry out the air the way radiators and forced-air central heating systems do, so there’s less need for electric-powered humidifiers. But possibly the best thing about radiant heat is that it keeps your feet warm—no more freezing tootsies when you first get up in the morning!
Among its many other green products related to keeping your home warm efficiently, Green Depot carries various components for a radiant heat flooring system. The Complete Radiant Panel is an easy-to-install, modular panel with heating tubes built in, for quick sub-floor assembly. Warmboard Radiant Heat Subflooring is plywood subflooring with grooves for heating tubes pre-cut, and Tyroc is a super-insulating overlayment for cold, damp concrete floors that you can lay your radiant heat flooring panels directly on top of. And soon to be added to the lineup is NuHeat, a system of soft mats with heating elements built in—sort of like an electric blanket for your floor. Neat, huh?
