Radiant Heating

Radiant heating is a type of heating system that uses radiation to heat objects and people in a space. It works by emitting infrared radiation, which is a form of light that isnt visible to the naked eye. This type of energy efficiently heats up objects in the room without relying on air circulation. Radiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house, and they depend largely on radiant heat transfer - the delivery of heat directly from the hot surface to the people and objects in the room via infrared radiation.

There are three types of radiant floor heat: radiant air floors (air is the heat-carrying medium), electric radiant floors, and hot water (hydronic) systems. Hydronic radiant floor systems, which are the most popular and cost-effective radiant heating systems for heating-dominated climates, pump heated water from a boiler through tubing laid in a pattern under the floor. In some systems, controlling the flow of hot water through each tubing loop by using zoning valves or pumps and thermostats regulates room temperatures.

Radiant heating has several advantages, including being more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. It is also preferred by people with allergies because it doesnt distribute allergens like forced air systems can. Additionally, hydronic (liquid-based) systems use little electricity, making them beneficial for homes off the power grid or in areas with high electricity prices.

In summary, radiant heating is an efficient and effective way to heat a space, providing warmth through the direct transfer of heat to objects and people in the room, without relying on air circulation. It offers several advantages over traditional heating systems, making it a popular choice for many homeowners.
