Four-Season Comfort: Sykesville Sunroom Transformed with Luxurious Radiant Floor Heating

Sunrooms, with their beautiful tile floors and walls of glass, often become unusable in colder months as they lose heat quickly. This homeowner in Sykesville, Maryland, wanted to reclaim their 258 sq. ft. space for year-round use. By installing a powerful TempZone™ radiant floor heating system, their contractor, Owings Home Services, LLC, transformed the room from a cold, seasonal space into a warm, welcoming retreat perfect for any day of the year.

Reclaiming the Sunroom with Radiant Warmth

The primary challenge for this 258 sq. ft. sunroom was its tile flooring. While beautiful and durable, tile is a poor insulator and becomes uncomfortably cold, especially in a room surrounded by windows. This made the sunroom a "three-season" room at best, limiting its use during Maryland's colder fall and winter months. The homeowner partnered with local experts at Owings Home Services, LLC to find a heating solution that was both effective and completely invisible.

Electric floor heating was the perfect answer. The installation team used WarmlyYours TempZone™ Flex Rolls, which are designed for quick and easy installation over a wood subfloor. The rolls were laid out to provide "Full" coverage, ensuring 15 watts per square foot of powerful, consistent warmth across the entire space.

The system was connected to a programmable nSpire Touch thermostat, allowing the homeowners to precisely control the floor's temperature and schedule heating times for maximum efficiency. Because the total system exceeded 15 amps, an nJoin power module was also installed to safely handle the electrical load. The result is a total transformation: the sunroom's tile floor now radiates gentle, consistent warmth from the ground up, making the room the coziest spot in the house, even on the coldest days.

Frequently Asked Questions

1. Can TempZone™ heating system be the only heat source in a sunroom?

In many cases, yes. This 258 sq. ft. system provides 3,870 watts of power, which is strong enough to be the primary or sole source of heat in a well-insulated sunroom, even in a climate like Maryland's.

2. How much does it cost to run radiant floor heating in a Maryland's large room?

Operating cost depends on your local electricity rate, system size, and usage. This large sunroom system costs about $0.50 per hour to operate. Using a programmable thermostat to schedule heat only when needed is the best way to keep costs low.

3. What is the best flooring for a heated sunroom?

Tile, marble, and stone—like the flooring used in this project—are ideal. They are excellent thermal conductors, meaning they transfer warmth from the in-floor heating system to the room quickly and retain that heat efficiently.

4. Is electric radiant floor heating energy efficient?

Yes. Radiant floor warming heats objects and people directly from the ground up, not the air. This allows you to feel more comfortable at a lower room temperature. By using a programmable thermostat to "zone heat" only the room you're in, you reduce the energy waste common with central forced-air systems.
