Radiant Snow Melting Systems put the NO in Snow

Radiant Snow Melting Systems Keep Snow at Bay

Radiant snow melting systems are a muscle-saving way to put the NO in snow. It happens every time the snow flies at many homes across the country; a small curse is heard pointed in the direction of the gloomy skies each time a snow flake lands its mark on an unheated driveway. Homeowners watch in dismay as the skies open up and dump white, harmless looking bits of snow crystals on their sidewalks and driveways. Shovels and snow blowers are taxed and so are backs, necks, and arms. Sure, it can be beautiful, but many people just want a way to say “no thanks” to snowy days and back-breaking efforts to clear their property.

Heated driveways are in vogue now and with great reason. Installing a driveway snow melting system saves time and money for every homeowner smart enough to add it to their property. Home values increase, winter blues decrease, and screaming body parts silence in homes that offer the perk of an automated radiant snow melting system.

Smart and savvy builders and home buyers are including snow melting systems in many large scale new construction projects as well as single dwellings. A heated driveway can be installed after construction as well, so the ease and affordable comfort is not merely limited to new construction.

If you live in an unforgiving climate where Mother Nature rules with white, then perhaps a snow melting system might help make the winters a bit more bearable and allow you to finally put the NO in snow!

Electric Snow Melting versus Hydronic

September 22, 2008 00:09 AM  BY  JEN BAKER

Electric snowmelt and hydronic snow melting systems both keep your driveway free of snow and ice, but which one is better? The debate over hydronic versus electric systems is ongoing and may not reveal immediate and apparent differences right away – so here is a breakdown of each type of system, to help you make a well informed purchase.

 

  Electric Snowmelt System Hydronic Snowmelt System
How it works The electric heating cables are embedded beneath cement, asphalt or brick pavers. Heat produced by the cables is transferred to the surrounding cement (or other material) and enables snow melting. Total components include: electric cables, automatic sensor unit, and manual control box. Closed-loop flexible polymer tubing embedded in cement (or thin concrete for indoor applications) pumps heated water (mixed with propylene glycol) through the tubing at around 140 to 180 degrees Fahrenheit. Heated water comes from a number of different sources such as: solar collectors, water heaters, boilers, demand water heaters, wood stoves and heat pumps.
Advantages
  1. Less expensive
  2. Easier to install
  3. Runs completely independent of fossil fuels. (Water heaters used by hydronic systems use gas.)
  4. No moving parts, which means less maintenance and chance of problems
  5. More efficient (99% of energy consumed goes into snow melting)
  6. Can be embedded under more materials, including asphalt, cement, and brick pavers. (Hydronic systems can only be embedded in cement.)
  7. Electric cables are more durable and less likely to corrode
  8. Can be installed into existing driveways using concrete saw cutting technology
  9. Can be easily configured for various types of installations (2 ft. tire tracks versus entire driveway)
  1. Can be used with existing boilers
  2. PEX tubing is more durable during installation
  3. Better for commercial and industrial applications (these buildings are usually already equipped with large boilers)
  4. More economical for heating large areas (approximately 4000 square feet and over)

 

Disadvantages
  1. Electric heat cables cannot be cut
  2. Control unit and automatic sensor must be installed by an electrician
  3. Large systems require a lot of amps to run and may be difficult to power
  1. Cannot be retrofitted into an existing cement lay
  2. Harder to install, usually requires professional installation
  3. Raises the floor significantly (a problem for indoor installations)
  4. Oxidation over time corrodes tubing

Hydronic heat is the oldest radiant heating technology, and has proven the test of time. While both electric and hydronic heat systems offer great advantages, the ease of use and flexibility of electric radiant heat makes it suitable for a larger number of applications. Ultimately, the system you choose will be based on your project parameters, size, budget, and location.

Installing Radiant Heat into Existing Concrete

January 06, 2008 00:01 AM  BY  BENSON RICKS

Heated driveway install using concrete sawcutWe are clearly into the time of year where the snow is upon us. When I was out shoveling snow off the driveway a few days ago I thought, wow, I don’t really need to be doing this. Oh sure it was great exercise, but I prefer a good runaround on a racquetball court as opposed to shoveling snow from the driveway. Why not turn your existing driveway into a heated driveway with the installation of a radiant snow melting system?

Retrofitting your driveway with radiant heat is not a major remodel project that you need to avoid. It really isn’t that difficult. Your existing asphalt driveway surface can be “grooved” and a grid of radiant heat cable can be laid out. (As a contractor, I can attest to the fact that Danfoss GX cable is by far superior to other heat cables.)

The cable can be embedded into the surface and as little as a half inch of asphalt covers the surface. You then have a radiant snow melting system. Get up in the morning and drive out to work. The bad news is that one excuse for being late has just been removed.

Radiant heated driveways are a nice way to simplify your life. Automated sensors switch on when the temperature and conditions indicate snow, turning your driveway into an energy-efficient radiant snow melting system. And you thought it was just a driveway.
