How It Works: Water Baseboard Heaters

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.

One 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 given by Chelmsford plumbing and heating 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. According to plumbers Essex, this radiator type structure is similar to the construction of radiators you would find in automobiles.


The quantity of water in a baseboard hot water heating system needs to be kept at a constant volume, and any loss of water has to be compensated from an overhead tank that contains the water storage. The function of the boiler is connected to the thermostats in the room or rooms being heated and when the temperature reading on these thermostats are increased a signal is sent which heats up the boiler and activates the pump to send water to the area demanding the heat needed.

It’s undoubtedly less expensive to plug in either of these single units to heat a small space rather than an entire home, the specific energy savings, heating times, and effectiveness will depend on factors unique to your home. These include the prices for electrical utility use in your area and even how well you’ve sealed leaks, drafts, and other issues in your home that let heat escape.
