How Do Hot Water Boiler Heaters Work?

Baseboard hot water heating systems, as their name implies, are typically installed at the baseboard or, at the very least, a point low to the ground. Since heat naturally rises, placing the heating element at the lowest point in a room is an easy way to evenly heat the air in a space.

    A unique benefit of using a water based heating system that relies on no form of forced ventilation is that the amount of dust that travels through the air in your home will be lower than in a home where a central air conditioner is blowing air through all the vents.

If the idea of using water to heat the air in a room still seems odd to you, the following information should clue you in on how hydronic baseboard heaters work and how to deal with any problems that could arise.

The hot water in the system is obtained from a boiler in a utility room, and this boiler is heated by gas, oil, or electricity. The hot water is pumped through a system of pipes that are installed in the baseboard. The heat from this hot water is transferred to the room, and once the heat transfer has cooled the water down again, it's piped back to the boiler room, replaced by a fresh influx of hot water, and reheated.

The hot water pipes on these baseboard heaters are typically made of copper and are uniquely fin-shaped to ensure faster dissipation of heat from the surface of the pipe. This radiator type structure is similar to the construction of radiators you would find in automobiles.
