How does water flow through a boiler?

The water pipe is actually one small section of a large, continuous circuit of pipe that travels right around your home. It passes through each hot-water radiator in turn and then returns to the boiler again. As the water flows through the radiators, it gives off some of its heat and warms your rooms in turn.

Your boiler powers on and uses either oil, gas or electricity to create heat. The heat from the fuel source is used to heat up water inside the boiler. The heated water or steam is sent throughout your home (via radiators or radiant floor systems) where it gives off its heat to warm the air.

Can a boiler explode?

What happens when water is heated?

An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.
