How Hydronic Systems Work
Hydronic heating systems use water to warm your home. The water heats up in a boiler. Then it flows through pipes to heat different rooms.
These systems provide steady and even heat. They use simple parts that work together to keep your space warm.
Heating The Water
The boiler burns gas to heat water. This hot water is the main source of heat in the system. The boiler controls the temperature to keep it safe and efficient.
Circulating The Water
A pump moves the hot water through pipes. These pipes run inside walls or floors to spread heat. The water cools as it travels, giving off warmth.
Heat Distribution Methods
- Radiators: Metal units that warm air around them.
- Baseboard Heaters: Long units along walls that radiate heat.
- In-floor Heating: Pipes under the floor heat the surface evenly.
Returning To The Boiler
After the water cools, it flows back to the boiler. The boiler heats it again to keep the cycle going. This process keeps your home warm all day.
Key Components Of Hydronic Systems
| Component | Function |
| Boiler | Heats the water using gas |
| Pump | Moves water through the pipes |
