Project Spotlight

Four-season sunrooms are a fantastic addition to any home, but in a climate like Minnesota's, "four-season" can be a challenge. The owner of this Maple Grove home faced a common problem: a beautiful new space that became unusable during the winter, making the engineered wood floors icy cold and the room itself unwelcoming.

The solution was to install in-floor heating before the final flooring was laid down. The project installer, ODA SmartHome, selected the TempZone™ Flex Roll system from WarmlyYours. This system is ideal for large, rectangular spaces like this, allowing for quick and simple roll-out installation over the wood subfloor. The 156 sq. ft. of heating roll was installed and then embedded in a layer of self-leveling cement before the engineered wood flooring was glued on top.

The result is a complete transformation. The room is now bathed in silent, even radiant warmth that rises from the floor, heating the entire space efficiently. Controlled by an nSpire Touch WiFi thermostat, the homeowner can program the floor warming schedule from their phone, ensuring the room is always comfortable. This radiant floor heating system turned a part-time room into a full-time luxury living space.

Frequently Asked Questions


In many cases, yes. A system like this, designed for 15 watts per sq. ft., provides significant warmth. For a high-heat-loss area like a sunroom in Minnesota, it serves as the primary comfort solution, ensuring the floor and room are always cozy.
Absolutely. Engineered wood is an excellent choice for radiant floor heating because it's more stable than solid hardwood and transfers heat effectively. This project used a glued-down installation, which provides a direct and efficient path for the warmth.
Operating cost depends on your local electricity rate and usage. This 176 sq. ft. sunroom (with 156 sq. ft. of heating) costs about $0.36 per hour to run, or under $3.00 for a full 8-hour day of consistent warmth.
Yes. Radiant floor heating is very efficient because it heats objects and people in the room directly, rather than just heating the air (like forced-air systems). This allows you to feel comfortable at a lower thermostat setting, saving energy.
