Do Bathroom Heated Floors use a lot of Electricity?
Electric underfloor heating systems are renowned for their energy efficiency, offering homeowners precise control over their heating schedules. By utilizing programmable thermostats, such as the nJoy WiFi LED Touch Thermostat and nTrust 2.0 Touch Nonprogrammable Thermostat, you can set the system to operate only during specific times—ensuring warmth when needed and conserving energy when not in use. This targeted approach eliminates unnecessary heating, especially during periods when the space is unoccupied.
For example, if you use your bathroom for about 1–2 hours daily, programming the floor heating to operate solely during those times can lead to significant energy savings. Considering the average electricity cost in the United States is 16.26 cents per kilowatt-hour (kWh), heating a small bathroom for 4 hours a day would cost approximately $0.10 daily, $2.93 monthly, and $35.61 annually.
It’s important to note that electricity rates vary by state. To obtain a precise estimate of your underfloor heating operating costs based on your specific location, you can use our operating cost calculator which allows you to input your zip code and receive tailored information.
Moreover, these systems are typically utilized during cooler weather, further optimizing energy consumption by aligning usage with seasonal needs. This strategic operation ensures that you maintain comfort without incurring unnecessary energy expenses during warmer periods.
Incorporating a programmable thermostat not only enhances the convenience of your underfloor heating system but also maximizes its energy efficiency—providcing warmth precisely when and where you need it while minimizing costs.

Prepare the Subfloor
• Ensure the subfloor is clean, dry, and level.
• Install suitable insulation boards to enhance heating efficiency and reduce heat loss.
Test the Heating Element
Before installing your electric floor heating system, use a digital ohmmeter to test the heating element to ensure it is functioning properly. Measure the resistance of the heating cable and compare the results to the value marked on the UL label. The reading should be within ±15% of the specified value. If the resistance falls outside this range, it may indicate a problem with the cable, such as a break or defect, that needs to be addressed before proceeding with installation. Performing this test before, during, and after installation helps verify the integrity of the system and prevents potential issues once the flooring is in place.
Lay Out the Heating Elements
Heating Mats vs Loose Cable
Heating Mats
• If using a heating mat, roll it out with the heating cable face down, ensuring even coverage of the open floor space.
• Carefully cut and turn the mat (without cutting the heating cable) to navigate around fixtures and fit the room’s layout.
• When reaching the end of a run, cut the mesh (not the cable) and turn the heating element to continue installation in the desired direction.
• If you encounter awkward corners or obstacles, you can freeform the cable by detaching it from the mat and manually positioning it to maintain proper spacing and coverage.
Loose Cable
• For loose wire systems, manually route the cables to cover the desired areas, maintaining consistent spacing.
Using Fixing Strips:
• Attach the fixing strips to the subfloor using screws or adhesive.
• Space them appropriately based on the SmartPlan installation recommendation.
• Lay the heating cable by weaving it back and forth through the strips, maintaining even spacing for uniform heating.
Using an Insulation Membrane:
• Roll out the insulation membrane and secure it to the subfloor.
• The membrane typically has pre-cut channels to accommodate the heating cable.
• Press the cable into the grooves, following the manufacturer’s spacing guidelines.
