A Warm Welcome for a Hard-Working Room

The Challenge: For many homes, the laundry room or mudroom is a purely functional space, and in New Jersey, that function often comes with cold tile floors for much of the year. This 53 sq. ft. room served as a primary entry and utility area, and the homeowner wanted to elevate it from a cold, utilitarian pass-through to a genuinely comfortable space. The challenge was to add significant comfort without a complicated HVAC overhaul, especially over the existing wood subfloor.

The Solution: The perfect answer was an electric radiant floor heating system from WarmlyYours. A 22.5 sq. ft. TempZone™ Flex Roll was selected for this project. The roll's flexible design allowed the installer to easily cut and turn the mesh to perfectly fit the room's layout, providing floor warming coverage exactly where it was needed. To maximize energy efficiency, CeraZorb® insulating underlayment was installed first, preventing heat loss into the wood subfloor and directing all the warmth upward into the tile.

The Outcome: The in-floor heating system was paired with a modern nSpire Touch programmable thermostat, giving the homeowner complete control over the room's heating schedule and temperature. The result is a laundry room that is now a warm and welcoming entry point to the home. The tile floors are comfortably warm to the touch, making chores more pleasant and eliminating the chill from this high-traffic area.


Featured Products

  • TempZone™ Flex Roll (TRT120-1.5x15): This versatile electric floor heating roll (1.5′ x 15′) provides 22.5 sq. ft. of heating coverage. It features heating cables affixed to a flexible mesh backing, allowing for simple and quick cut-and-turn installation, ideal for rectangular or open areas.
  • nSpire Touch Thermostat (UDG4-4999-WY): A 7-day programmable thermostat with a 3.5” color touchscreen. It includes a floor sensor, built-in Class A GFCI protection, and energy use monitoring to help keep operating costs low.
  • CeraZorb® Insulating Underlayment (CZRG-SH5MM-24X24): This synthetic cork underlayment is essential for efficiency, especially over wood subfloors. It provides a thermal break to stop heat from escaping downward, ensuring the radiant heat is directed up into the flooring, improving warm-up times and reducing energy use.

* This 22.5 sq. ft. in-floor heating system costs just about $0.09 per hour to operate. Based on average New Jersey electricity rates (approx. $0.2531/kWh as of late 2025), that’s only $0.72 for a full 8 hours of use, or less than $22.00 a month to add luxurious warmth and everyday comfort to this busy room.

Frequently Asked Questions


The operating cost depends on the system size and local electricity rates. For this 22.5 sq. ft. heated area in New Jersey, the cost is approximately $0.09 per hour. If run for 8 hours a day, that totals about $0.72 per day, based on 2025 energy prices ($0.2531/kWh).
This project used tile, which is an ideal flooring material. Tile, marble, and stone are excellent conductors of heat, transferring the warmth from the TempZone™ system to the room efficiently and evenly.
Yes. Electric floor warming is very efficient because it heats the objects and people in the room directly (via radiant heat), rather than heating the air. When combined with an insulating underlayment like CeraZorb® and a programmable thermostat, the system minimizes energy waste and directs heat only when and where it's needed.
Absolutely. The TempZone™ Flex Roll system is designed to be safely and effectively installed over a wood subfloor. In this project, CeraZorb® underlayment was placed on the wood subfloor first, followed by the heating roll, and then the tile was installed on top using thin-set mortar.
