A beautiful 242 sq. ft. sunroom in Madison, Wisconsin, suffered from cold tile floors, making it unusable for much of the year. Brian H Remodeling partnered with WarmlyYours to install a powerful 3149-watt TempZone™ electric floor heating system. The result is a truly four-season room, adding luxurious comfort, energy-efficient warmth, and significant value to the home.

From Cold-Spot to Comfort-Zone

Sunrooms are a wonderful home addition, but in a climate like Madison, Wisconsin, their tile floors can become ice-cold, rendering the space uncomfortable for months. The challenge for this 242 sq. ft. project was to deliver enough heating power to transform this large room from a seasonal space into a year-round oasis, especially given the high potential for heat loss through the many windows.

The experts at Brian H Remodeling selected a high-performance WarmlyYours TempZone™ Flex Roll system. Spanning 210 sq. ft. of the room, the 240V system delivers over 3100 watts of consistent, radiant warmth. The Flex Roll product is ideal for large, rectangular spaces, allowing for fast and simple installation over the wood subfloor before the final tile flooring was laid.

Paired with the programmable nSpire Touch thermostat, the homeowners now have complete control over their new, cozy environment. This powerful electric floor warming system radiates warmth upward, heating the tile and the entire room efficiently, successfully turning the home's coldest room into its most comfortable retreat.


Featured Products

This project combined our most popular roll system with a smart thermostat for maximum efficiency.

  • TempZone™ Flex Roll Our TempZone™ Flex Roll system is designed for quick and easy installation in large or rectangular areas. It features a heating cable secured in a durable mesh, providing 15 watts per sq. ft. for powerful and even floor warming, making it perfect for high-heat-loss areas like sunrooms.
  • nSpire Touch Thermostat This programmable, full-color touchscreen thermostat provides intuitive control over your radiant heating system. It includes a floor sensor, built-in Class A GFCI protection, and a setup wizard for easy programming, helping you maximize comfort and energy efficiency.

* Running this 210 sq. ft. sunroom system costs approximately $0.63 per hour. This calculation is based on the system's 3149-watt draw and the average Madison, WI residential electricity rate of approximately $0.20 per kWh. This means enjoying a full 8-hour day of luxurious warmth costs about $5.04, or less than $152 per month to add a comfortable, fully-usable living space to this home, even in the coldest months.

This project used tile, which is an ideal conductor for radiant floor heating. Stone and marble are also excellent choices for maximizing heat transfer. Our TempZone™ systems are approved for use under laminate, engineered wood, and even luxury vinyl flooring.
Yes, in many cases. This 210 sq. ft. system was designed for "Full" coverage, providing enough power to act as the primary heat source for this sunroom, combating the cold from the large windows and tile floor. A formal heat-loss calculation can confirm if a system can be a primary source for your specific space.
Electric radiant floor heating is highly efficient. It heats objects and people directly (not just the air) and allows for precise "zone heating," so you only warm the room you're using. When paired with a programmable thermostat, you can avoid heating an empty room, saving energy compared to whole-home forced-air systems.
