Hydronic heating is most recognizable in older homes, which often used radiators filled with heated water to warm each room. Hydronics systems are still used to heat homes today, however in modern applications, they use small tubes fitted underneath the floor that transfer heat from hot water to the air in the room. In-floor Hydronics are a great choice for tile and other floor surfaces that can feel cold underfoot. Since they warm from the floor up, they can give any room a cozy feeling.
Hydronics systems typically use either electricity or gas to heat the water, and they employ a boiler to heat the water, as well as a pump to distribute it. Since in-floor systems keep the warm air closer to the ground, where it is most needed, they can be a very energy efficient option.
