4. In-Slab Heating Cable System

In-Slab Heating Cable System

The In-Slab Cable electric underfloor heating system works best when installed on concrete floors between 2 and 6 inches thick.

Because it takes longer for the In-Slab Cable to warm up and cool down, it’s perfect for rooms that are used all the time. The concrete floor acts like a storage heater, keeping the room cozy even after the heat is turned off.

How to Pick a Suitable Radiant Floor Heating System

Let’s break down the most important things you must remember when choosing between electric and hydronic radiant floor heating systems:

Factors to ConsiderElectric SystemsHydronic Systems
Installation ComplexityGenerally easier to install, suitable for DIY installation in smaller areas.More complex installation process that may require professional expertise and specialized equipment.
Energy EfficiencyCan be highly efficient when combined with programmable thermostats and zoning controls.Offer high energy efficiency, especially when paired with high-efficiency boilers or water heaters.
CompatibilityCompatible with various types of flooring, including tile, laminate, and hardwood.Compatible with most flooring types but may require additional considerations for compatibility with existing heating systems and infrastructure.
MaintenanceMinimal maintenance is required, with occasional inspection of heating elements and thermostat.Regular maintenance is required for boilers, pumps, and piping, including annual inspections, system flushes, and potential repairs.
Long-Term DurabilityDurable and reliable heating elements that typically last 15-30 years.Generally durable, can last 20-50 years with proper maintenance, boilers, and piping.
Comfort and PerformanceProvides consistent and even heat distribution throughout the room.Provides a consistent heat output, resulting in a more uniform output in larger areas or whole-house heating applications.
Zoning and Control OptionsOffers a wide range of zoning and control options, allowing for customizable heating schedules and temperature settings for individual rooms or zones.Provides flexibility for zoning and control options, but may require additional components such as zone valves or pumps to achieve desired control over different areas of the home.

Cost Considerations

The cost of installing electric radiant floor heating can vary depending on factors such as the size of the area, type of flooring, and complexity of the installation.

Initial Investment

While electric systems are generally more affordable upfront than hydronic systems, the total cost can vary depending on factors.

This includes things like:

The initial cost for electric systems is moderate, typically ranging from $7.9 to $15 per square foot. 

Hydronic systems have a higher initial cost, averaging between $6 to $20 per square foot, primarily due to the cost of boilers, pumps, and installation labor.

Materials and Components

The cost of materials and components for electric radiant floor heating typically includes heating mats or cables, a thermostat or control system, and any necessary tools for installation.

Consider any additional materials needed for subfloor preparation, such as self-leveling compound or insulation.

Installation Labor

If you’re uncomfortable installing the system yourself, you’ll need to budget for professional installation labor. 

Labor costs for radiant floor heating installation typically range from $550 to $2,500 in total. The cost of installation can vary depending on the complexity of the project, the accessibility of the installation area, and local labor rates.

Operating Costs

Electric systems are generally more energy-efficient than traditional forced-air heating systems. They can run at $0.08 to $0.12 per hour, resulting in potential savings. Hydronic systems usually range from $0.10 to $0.15 per square foot per hour, which can quickly add up over time.

TAKE NOTE: The exact operating costs can vary depending on electricity rates, usage patterns, and the system’s efficiency.

The Downsides of Underfloor Heating

Underfloor heating systems offer a modern and seamless way to heat your home, but there are some considerations to keep in mind before installing one. Here are the potential drawbacks:

Impact on Flooring Materials

  • Natural Hardwood: Could be susceptible to warping or cracking due to fluctuating temperatures.
  • Vinyl Flooring: May degrade or become discolored when exposed to prolonged heat.
  • Tip: Ensure compatibility of your flooring materials with underfloor heating to prevent damage and premature wear.

Incompatibility with Furniture and Fixtures

  • Heavy or bulky furniture can obstruct heat distribution, causing uneven heating patterns.
  • Built-in cabinets or kitchen islands may restrict airflow and reduce the efficiency of the heating system.
  • Tip: Plan room layouts carefully and consider furniture placement to optimize heat distribution and system efficiency.

Floor Height and Door Clearance

  • The addition of an underfloor heating system can raise the floor level, affecting door clearances and room height, especially in older homes.
  • Tip: Consider the impact on floor height and door clearance during the planning phase to avoid any inconvenience or the need for modifications.
