What is a hydronic boiler system?
Hydronic heating uses water to carry heat through a building. This efficient, versatile system can warm radiant floors, baseboards or radiators. Here is how its parts work together:
- 01
Boiler
The boiler heats water to a set temperature using natural gas, oil, electricity or solar energy. The heated water then circulates through a network of pipes.
- 02
Piping
Pipes carry hot water through floors, walls or ceilings. They are usually copper, PEX or another material designed for hot water.
- 03
Radiators, baseboards, or radiant flooring
Hot water flows through radiators, baseboard heaters or pipes embedded in floors and ceilings. Radiators are common in older systems. Each releases heat into the surrounding space as water passes through it.
- 04
Heat distribution
Heat from these surfaces warms the room's objects and air. Radiant heat provides consistent warmth without forced-air blowing, which can sometimes cause uneven temperatures.
- 05
Circulation
A pump circulates water between the boiler and the heating elements. This continuous flow maintains the desired temperature throughout the building.
Hydronic heating systems are known for their efficiency, even heating, and quiet operation. They can be controlled through zone valves or thermostats to provide individual temperature control for different areas or zones within a building. Additionally, they can be integrated with other technologies, such as solar thermal collectors, to further enhance energy efficiency.
Hydronic systems are popular for both residential and commercial applications, and they are often chosen for their ability to provide comfortable and customizable heating solutions.
