Snow Melting for a Concrete Patio
Follow our detailed guide and learn how to install a snow melting system for a concrete patio, so that you can keep every square foot of your outdoor spaces snow and ice free.
The patio is your oasis—a place where you can kick back, relax, and unwind. But winter has a bad habit of ruining that by dumping huge amounts of snow on your patio. Even if you go through the backbreaking labor of shoveling it off, you'll still be left with a dangerous layer of ice.
By installing a WarmlyYours snow melting system in a new patio or veranda construction, you can make sure your patio stays clear of snow and ice throughout the year—great for late season grilling or just getting a few moments of fresh air.
Why Heat Your Concrete Patio?
What is Snow Melting?
If you're a home owner and you've ever wondered, "how can we reduce the freezing of snow on my patio?", then radiant snow melting systems can be of assistance to you and your loved ones.
Have you ever seen snow fall on an already warm car? It melts instantly. This is the essential idea behind snow melting systems—a heating element is embedded in your patio (or driveway, walkway, etc.) and it melts the snow that falls on it.
Like any outdoor surface, a new patio can benefit from installing a WarmlyYours snow melting system (available in both mats and cables). Designed to install directly in mortar beneath pavers, concrete or asphalt, our systems ensure that patios stay ice and snow free.

When to Install Snow Melting in a Patio
Because the snow melting system is embedded within the surface itself, the best time to install a snow melting system is when a patio or porch is either being created or during a complete patio renovation.
These kinds of projects are typically undertaken from late spring to late fall when ground temperatures are above freezing.
The snow melting heating elements must be installed within the patio itself, approximately 2-3" beneath the finished surface. This spacing ensures the optimal performance of your system.
The thinness of an electrical snow melting system (1/4" for cables and 5/16" for mats) means it has a minimal impact on the overall depth of the project.
Installing the Snow Melting System
The key to a successful snow melting system is in how it's embedded. If it's too deep, it won't effectively melt snow or ice. If it's too shallow (or exposed), it could overheat and fail.
Follow these steps for a successful concrete patio installation:
Step 1. Laying Down a Rebar Frame or Wire Mesh
To make sure your heating element is the proper 2-3" from the final surface, many installers will use a rigid framework (rebar or wire mesh) that is propped up so that the heating element is exactly where it needs to be.
Tip: For your framework, avoid using a metal mesh or frame that has sharp edges or burrs.
Step 2. Dry-fitting Your Snow Melting System
Once you have your framework in place at the proper depth, it's a good idea to layout your snow melting system before you're ready to attach it.
Using your WarmlyYours SmartPlan should help make this process as smooth, and as accurate, as possible.

Step 3. Start Laying Out Snow Melting Mats
The snow melting mats are designed to maintain the desired 3" spacing of the heating cables.
The heating elements should be attached to the mesh using wire ties or zip-ties to maintain proper depth and spacing.
Attaching them keeps the heating element flat and prevents it from "floating" too close to the final surface when the concrete is poured.
Step 4. Making Sure the Manufacturer's Splice is Embedded
The power is carried to each cable by a "cold lead," which is connected to the heating cable on the mat via a manufacturer's splice.
One of the most common installation mistakes is leaving this splice outside of the concrete. This can cause the splice to overheat and fail.
Always ensure the splice is embedded in concrete, sand, mortar, or stone dust.
Step 5. Pouring Concrete
Concrete installs can be done in two ways: 1-stage pours or 2-stage pours.
For 2-stage pours, pour an initial base layer, then lay the framework while still wet, then apply the second 2-3" layer.
For 1-stage pours, prop up the framework and pour concrete on, around, and over it.
The Finished Heated Patio
Once the patio is completed, it's ready to be used. Just add snow! This particular patio featured a beautiful rolled faux-wood finish along with wrought-iron patio furniture and a built-in fire pit.
Just imagine how nice it will be to use your patio in the dead of winter to let your pets out, or simply enjoy a minute outside of the house.
Controls for Patio Snow Melting
WarmlyYours offers a wide variety of controls for our snow melting systems—from a manual option with a timer to an automatic option that will turn on when it senses snow is falling.
These controls are able to function with the use of sensors. There are two main types: slab sensors (installed with the heating element to measure surface conditions) and aerial sensors (installed in the open to detect whether it's snowing).
