Radiant Floor Heating

HYDRONIC Radiant Living has become one of today’s most sought after ways to heat your home. While it costs more initially to install, the notable savings will come when you compare fuel costs between forced air and radiant heating. Forced Air Systems generally use twice as much fuel as HYDRONIC Radiant Systems, due to convective currents. Convection transfers heat by the flow of a gas (air). A gas expands when you heat it, and decreases in density. In other words, it gets lighter. The lighter, warm, air will rise through the cooler, less dense, air creating convective currents. Thus, hotter air at the ceiling, cooler air at the floor. The hotter air at the ceiling wants to get to a cooler place, and that cooler place is the attic. The greater the temperature difference between the attic and the hot ceiling, the more heat loss to the attic. This results in higher heating bills, due to the greater heat loss. HYDRONIC Radiant heat is equal in temperature from floor to ceiling, resulting in less heat loss to the attic. If the floor is 70 degrees then the ceiling is around 68-70 degrees.

HYDRONIC Radiant Heat is the transmission of energy in the form of waves, an example of waves is sun light. Have you ever stood in front of a window on a sunny day and felt the suns rays warm your skin? This is Radiant Heat at its best! Energy, or waves travel at a different wavelengths. And that brings us down to the business about heat rising. Heat doesn’t actually rise you know? It moves through a solid object, or rides on a gas or liquid, or flies through space. Heat always goes to cold, because mother nature always wants to equalize everything. Hot air rises, not heat!!

That’s why HYDRONIC Radiant Heat is so comfortable, you’re not heating the air so you have no air currents. And no air currents means less body heat loss due to evaporation, resulting in more comfort. Radiant heat is more involved with heating up objects in a room, than heating up the air, unlike a forced AIR system. No more cold feet, while walking barefoot on tile, wood, carpet, or vinyl flooring.

Today’s HYDRONIC Radiant Systems are designed around comfort, energy savings, and ease of operation. Usually incorporating multiple zones, night setbacks, outdoor temperature resets, and indoor feedback (via the thermostats). Today’s systems may also incorporate boiler- heated domestic hot water ( potable water), towel warmers, spa tub heaters, and snow melt systems for driveways, sidewalks, and parking lots.

Zoning usually consists of putting bedrooms and bathrooms on separate zones from other parts of the house. This is to make sleeping quarters independent of main living quarters and provide better temperature control for the occupants.

The most common floor piping material used is Oxygen Barrier PEX pipe. PEX has shown excellent characteristics for floor heat applications, and has been around since the early 1970’s. Typical tube spacing on the floor is 6″ to 12″, and concrete is 1.5″ to 2″ above the pipe which is imbedded in the slab. Or a staple-up method can be used in floor joists where piping is looped through the floor joists. The floor joists are insulated with foil-backed insulation which directs the radiant heat to the floor. Also, GYP-CRETE can be poured on 2 and 3 story buildings as an alternative to staple-up methods, and is far more superior because of its thermal mass and lightweight properties.
