I have noticed some houses in my area have heated driveways. I found www.warmzone.com online and want to know if anyone has used electric cables to heat their driveway or walkway. Is electric radiant heat better than hydronic radiant heat to heat my driveway?

I've seen cable installations in sidewalks of some businesses & they work great. You will probably need a beefy service depending on how many square feet of driveway you're going to cover. The only number I found at the web site you listed was 30 watts/sq.ft. Thats 30,000 watts to do 1000 square feet of driveway and that translates to a load of 125 amps.

Operating cost is another factor I'd think about also. For every 33 square feet, it will cost you 7¢ an hour (or whatever your kwh rate is).

The only driveway around here that I know of that is heated is done with a regular natural gas water heater & circulating pump in spite of our reasonably low kwh cost.

Hopefully you found something you liked and might want to share how it’s working for you? I checked out the link you posted and ended up here: http://www.warmzone.com/site/page/clearzone.

What I liked about the ClearZone System is that I don’t have to tear up my driveway to get what I want. I have many options. Retrofits fit our budget nicely. Hydronic systems are efficient, but my options seem limited.

What really sold me on electric radiant heat is my neighbor’s heated driveway. He’s got back problems and his driveway is huge! Now his driveway is the first one clear in the morning. And he’ll be the first one to tell you how much he’s saved since he fired his snow removal service.

It appears that the company you referred to (www.warmzone.com) carries both hydronic and electric systems. But from what I've learned, I think electric systems do the job better and more efficiently. My brother is a tile setter and has installed heated floors (both hydronic and electic), and in terms of ease-of-installation and performance, he's sold on the electric systems. Now, if you have a huge driveway, maybe the operating costs of a hydronic system would be a little less (depending on your local utility rates), but I'm not certain. I too am looking at installing a heated driveway, and I've pretty much settled on an electric system because I don't have room to house a mechanical room (boiler, pumps, etc.) for a hydronic system.
