If you’ve decided to add a heated driveway or underfloor heating system to your list of home improvement projects, hydronic heat might be the popular choice, but it’s not necessarily the best, or least expensive way to go. Electric radiant heat is a new, equally viable option that may give you some pause when it comes time to fork over that cash you’ve been stashing for your home improvement projects.

Installing tubing for hydronic floor heating system.

Let’s say you are considering adding radiant heat to your bathroom-remodeling project. In a small space, typical heating times can make all the difference, right down to the floorboards. A hydronic heated floor system installation requires PEX tubing placed 1½-2 inches into a cement slab for optimal results. At this depth, you could be waiting a few hours for things to heat up. To avoid the inconvenience of those long wait times, most homeowners tend to leave their hydronic heat systems on throughout the winter months, consuming more energy. An electric radiant heated floor can reduce that wait time by as much as 6½ hours. Radiant heating mats can be easily rolled out above the sub-floor, just under the flooring material, and can heat a tile floor in 30 to 60 minutes flat. With more reasonable wait times, programming the system to turn on and off potentially saves you more dollars, and frankly, makes more sense.

Installation costs tend to be higher for hydronic heating systems. Returning to our bathroom project, the $300 to $400 you would expect to spend installing a radiant heated floor will cost you upwards of $4,000 to $5,000. The upfront investment for equipment, labor and floor height issues make hydronic systems cost prohibitive in small- to medium-sized areas. Hydronic systems require a boiler, which accounts for a big chunk of the budget. Unlike radiant heated floor mats, hydronic floor heating systems also elevate the floor by a couple of inches, a significant difference that can cause big problems for you during your bathroom remodeling job. Radiant heated flooring installed will elevate the floor by only ⅛ of an inch. In this scenario, at least, it probably would not make much sense to run hydronic tubes in your bathroom.

Of course there is the issue of maintenance and repairs. Hydronic systems circulate continuously, and rely on a system of valves and manifolds prone to sedimentation, mechanical problems and maintenance issues. If a hydronic heating system installation is faulty, it is difficult to find a leak, and because of the nature of the installation, even if the leak is found, it is difficult to repair. With electric radiant heat systems, fault detectors can pinpoint the exact location of a break. After breaking just one or two tiles, the electric cable can be spliced and the tiles replaced, a far better (and less costly) scenario than I’m imagining with our hydronically-heated bathroom floor. Fortunately, Warmzone’s electric floor heating systems are built to last and feature the best warranty in the business. 

Generally, most homeowners opt for electric radiant heating. It’s well suited for small- to mid-sized home improvement projects. And the initial investment is modest enough that you won’t find yourself over your head, or under water when it’s time to tap into your home improvement budget.
