Radiant System Design
We calculate heat loss for each room, then determine tube spacing, loop lengths, water temperatures and manifold locations so the floor delivers enough heat without becoming uncomfortably warm.
Heating
Radiant floor heating in Roswell, GA. Whole-home and large-area hydronic or electric radiant systems designed from heat loss as a primary source of heat.
Radiant floor heating warms the floor itself, which then gently heats people and objects in the room. There are no drafts, no blowing dust and no visible registers, making it a favorite for open living spaces and allergy-sensitive households during spring pollen season. Our radiant floor heating in Roswell service designs radiant systems meant to serve as a primary heat source for whole homes, basements, additions and large open areas. Most of these projects use hydronic tubing fed by a boiler or water heater, while smaller zones may use electric cable. Design is everything: we calculate heat loss, choose tube spacing and loop lengths, and check that your flooring, whether tile, hardwood or polished concrete, transfers heat well. Installation methods include tubing embedded in a concrete slab, set in a thin pour over a subfloor, or attached beneath the subfloor with aluminum heat transfer plates.
We calculate heat loss for each room, then determine tube spacing, loop lengths, water temperatures and manifold locations so the floor delivers enough heat without becoming uncomfortably warm.
For new construction, basements and additions, we lay PEX tubing over insulation before the concrete pour, creating a durable, evenly heated slab that works as the main heat source.
In existing homes, we can attach tubing with aluminum transfer plates beneath the subfloor from a basement or crawlspace, adding radiant heat without tearing up finished floors above.
Tile and stone conduct heat best, while thick carpet resists it. We review your flooring plans and adjust design temperatures so the system performs well under each surface.
Radiant floors need lower water temperatures than radiators. We install manifolds, mixing valves and circulators that deliver the right temperature to each loop and zone throughout the home.
Thermostats with floor and air sensors keep each zone comfortable and protect sensitive flooring from overheating, while separate zones let bedrooms and living areas run independently.
Radiant floors are designed, not just installed. A good system starts with accurate heat loss numbers and careful layout, because tubing buried in concrete cannot be easily changed later. We plan each project in detail, coordinate with builders and flooring installers, and pressure test every loop before it is covered.
We also help you decide whether radiant floors make sense as your main heat source or should be paired with another system for cooling and humidity control, which matters in Georgia's humid summers. You get honest guidance about cost, response time and flooring choices, so the finished system matches your expectations from the first cold morning. We also explain realistic warm-up times, since slab systems respond slowly, and show you how setback schedules and outdoor reset controls help keep the floors comfortable while using energy wisely.

We review your floor plans, construction method and flooring choices, calculate heat loss, and create a loop layout with tube spacing, manifold locations and zoning for the whole project.
Our team installs insulation, tubing or cable, manifolds and controls, then pressure tests each loop before concrete, thin-set or subfloor coverings are placed over the system.
We connect the heat source, fill and purge the loops, set mixing temperatures and floor sensor limits, and verify each zone warms evenly before turning the system over to you.
FAQ
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
Yes, a properly designed radiant floor system can serve as the main heat source for a whole home, as long as heat loss is calculated carefully and the floors can deliver enough output. Rooms with very high heat loss may need supplemental heat. Since radiant floors do not cool, homes in Roswell still need a separate air conditioning system.
Tile, stone and polished concrete conduct heat best and are ideal over radiant floors. Engineered wood and luxury vinyl work well when installed according to manufacturer guidelines for heated floors. Thick carpet and heavy pads insulate the floor and reduce heat output, so we account for flooring choices during design and adjust water temperatures accordingly.
Slab systems with tubing embedded in concrete respond slowly, often taking several hours to change temperature noticeably, which is why they work best on steady settings. Thin-pour and under-subfloor systems respond faster. Outdoor reset controls help by adjusting water temperature ahead of weather changes, keeping floors comfortable without large temperature swings.
For whole-home or large-area heating, hydronic radiant is usually more economical to operate because a boiler or water heater can heat water efficiently. Electric radiant costs less to install and suits smaller zones or single rooms. We look at the area to be heated, your fuel source and your budget to recommend the right approach.
Cost depends on the area being heated, whether tubing goes into a new slab or is retrofitted under an existing floor, the heat source, number of zones and the controls you choose. New construction is generally simpler than retrofit work. We design the system first and then provide a written, upfront quote based on that design.
