Radiant heating systems work by using the floors as a heat conductor. A contractor installs electric coils or water tubing beneath the floor, making sure to cover the entire surface area. In a hydronic system, the tubes are connected to a boiler that heats water, while a pump circulates the hot water throughout the house. In an electric system, the power source sends electricity to the coils to activate the heating mechanism. Each system must use a set of controls and a thermostat to regulate the temperature of the water or coils to achieve the ideal room temperature.

The heat from the pipes or coils radiates up through the floor covering and warms the foundation of the building, so the heat from the rooms is not lost to the walls and floors. The radiant heat constantly warms the air in each room from the bottom up, ensuring that the warmest air does not sit near the ceiling.
