Heated Driveways: Who, What, Where, When, Why & How
The obvious answer is "a driveway that is heated." But what actually heats the driveway? The best heated driveway systems are
electric radiant heating systems, similar to indoor floor heating systems. There are primarily two methods for heating
driveways (and floors): electric and hydronic. Electric systems use heat cable, while hydronic systems generate hot water, then pump it through plastic PEX tubing. The heating elements are embedded
under the surface and use radiant heating to heat the surrounding area.
Most heated driveway systems incorporate an automatic sensor that detects inclement weather to activate the system. Electric
radiant heated driveway systems tend to be more efficient, require less maintenance, and heat surfaces quicker. Hydronic systems are usually slightly more expensive to purchase and install, but the operational costs can be lower, depending on the local fuel rates. Both systems have their advantages; however, the electric systems are gaining
popularity due to their price, ease of installation, and the uncertain future of
fossil fuel costs.
Why Install a Driveway Heating System?
Some of the obvious benefits of a radiant driveway heating system are, of course, not having to shovel your driveway again, avoiding injury due to slippery surfaces, and having the confidence that your driveway will be cleared,
regardless of the weather conditions. Other notable benefits include adding value to your home, preserving the life of your driveway, and avoiding damage to
the bordering landscape from harmful salts and chemicals.
Where and when can you
Install a Radiant Heated Snowmelt System?
A radiant heated driveway or snowmelt
system can be
installed in almost any medium (including concrete, asphalt, under pavers, etc.),
in just about location, and nearly at anytime of the year (depending on the medium). The most popular and ideal time to install a system is during new construction. However, with weather permitting, there are no limitations as to when a snowmelt system can be installed,
and a variety of custom
options. Additionally, asphalt driveways can be easily
retrofitted with a radiant heat system.
How do Heated Driveway Systems Work?
Driveway snow melting systems are composed of three main items: the heating element, the controller, and the activation device. The heating element can be either an electric resistance cable or PEX hot water tubing
(for hydronic systems). These heating elements can be installed in almost any medium. The simplest application for installation is under brick or stone pavers and in new pour concrete. Asphalt can also be used, but the installation methods call for more care and labor to avoid injurious contact to the cable because of the asphalt's temperature and abrasive nature during the paving process.
Warmzone ClearZone heat cable is the premier snow melting cable, and the only heat cable capable
of withstanding the extreme temperatures of fresh asphalt installation.
Heated driveway systems are controlled by either a
wall-mounted control box for electric systems or a small mechanical room to house a boiler, pump, manifold, etc., for hydronic systems. Both types of systems use manual and/or automatic activation devices. Available
automatic sensors include aerial-mounted or pavement-mounted snow switches. These sensors activate the system when there is moisture present and the temperature is below approximately 38 degrees. Most systems also include a manual timer to preheat an area before a large storm to curb snow and ice accumulation.
Who Installs Radiant Heated Driveways and Who Sells Them?
Electric snowmelt systems are fairly easy to install, and any
experienced "do-it-yourselfer", contractor, or electrician would be
a candidate for installing a system. There are several vendors of
driveway heating systems; however, Warmzone is an established,
dedicated source for matching your project to the best valued
solution. Warmzone is the consumer and contractor advocate without
bias towards any one system. They will point out the obvious
benefits and challenges to any project and recommend a system that
makes sense. Warmzone has extensive experience with both residential
heated driveway and roof deicing systems as well as large commercial
