4/12 What is Radiant Heat and How Does it Work?

Experience the sublime comfort of radiant heat, a contemporary approach to warming your space with either hot water or electric coils. Unlike conventional heating systems, radiant heat directly warms objects and surfaces, fostering an even and snug diffusion of heat. Hot water radiant heat employs a boiler or tankless water heater to circulate warmth through pipes ingeniously concealed beneath the floor or discreetly nestled behind walls.

Conversely, electric radiant heat employs coils seamlessly integrated beneath the flooring material. Both techniques guarantee a harmonious distribution of heat, banishing any trace of chilly areas. Bid farewell to draughty rooms and revel in the enticing embrace of radiant heat.

5/12 The Advantages of Using Radiant Heat Systems

Homeowners are increasingly turning to radiant heat systems for their homes, and it’s not hard to see why. These systems offer a multitude of advantages that make them a smart choice. One of the key benefits is their energy efficiency, which leads to cost savings.

Unlike forced-air systems, radiant heat systems transfer warmth directly through objects and surfaces, minimizing heat loss and using energy more efficiently. But that’s not all. Radiant heat systems also provide a more even and comfortable heat distribution.

Unlike traditional heating systems that tend to concentrate warm air near the ceiling, leaving the lower parts of the room cooler, radiant heat systems evenly distribute heat throughout the entire space. This creates a cozy environment that is perfect for relaxation and comfort. One of the standout features of radiant heat systems is the ability to control the temperature in individual rooms.

With separate thermostats , homeowners can customize the temperature according to their preferences. This not only ensures optimal comfort but also saves energy by lowering the temperature in unused rooms. In summary, radiant heat systems offer increased energy efficiency , a more even heat distribution, and the flexibility to control temperature in individual rooms.

These advantages make them the ideal choice for homeowners in search of efficient and customizable heating solutions.

How hot does water have to be for radiant heat?

Radiant-floor heating systems usually utilize water temperatures ranging from 85–140°F (30–60°C). In comparison, baseboard hydronic systems operate at higher temperatures of about 130–160°F (55–70°C). This difference in temperature leads to a longer lifespan for boilers in radiant-floor heating systems, with some lasting up to 45 years, as stated by the Department of Energy (DOE).

How does hot water radiant heat work?

Hydronic radiant floor systems use a boiler to pump heated water through tubing placed under the floor in a specific pattern. This system allows for control over the flow of hot water in each tubing loop, ensuring efficient regulation of room temperatures. Zoning valves, pumps, and thermostats are employed to adjust the flow of hot water in different areas of the floor, providing customized comfort and energy savings.
