Are hydronic baseboard heaters worth the moneyBefore installing baseboard heaters, it’s important to take into account the electrical codes associated with them.

A heater without enough capacity won’t heat the space properly, and you’ll find yourself using it much more often and at much higher temperatures.

Electric hydronic baseboard heaters come in either in 120- volt or 240-volt models.

  • A 120-Volt Baseboard Heater 

A 120v hydronic baseboard heater is most suitable as a supplemental source of heat to zones and seasonal rooms.

  • A 240- Volt Baseboard Heater 

A 240v hydronic baseboard heater is best used as a hard-wired baseboard heater that is wired directly into a household circuit to act as the central heating system. 

2. Best Size Hydronic Baseboard Heater

Manufacturers have Hydronic baseboard heaters with different specifications ranging in terms length from 24 inches to 96 inches. The longer the baseboard heater the more wattage it is going to produce.

If you are unsure of what length you should get that will offer sufficient heat, determining the measurement is a practical easy procedure.

  • Step 1

Measure the length and width of the room to determine the square footage.

  • Step 2

Multiply the square foot answer to 10 watts. The figure is the baseline wattage per square foot. 10 is an average watt required to heat a square foot. You generally need 10 watts per square foot.

  • Step 3

Determining the total wattage of a typical room is run by adding 10% to each window, exterior wall, uninsulated space, and poorly insulated wall

Divide the answer by 240 to get the length of the hydronic baseboard heater. The 240 factor is the voltage of a typical baseboard heater.   

For example,

  • Assuming a 225 square foot room.
  • Multiplied by 10 to give 2250 watts.
  • Add 10% for one window to get 2475 watts.
  • Adding 10% for an uninsulated wall to get 2722.5 watts.
  • Then dividing the figure 2722.5 by 240 factor you get 11 inches.
  • Rounding this figure to get an estimated length of 12 inches which is a 96-inch long baseboard heater.

1. What Is A Hydronic Baseboard Heater?

You may wonder, what is a hydronic baseboard heater?

To answer the question, let’s isolate each component of the word Hydronic baseboard heater.

It’s called hydronic because it uses a liquid as a medium. The liquid is typically water or mineral oil.

The use of the words baseboard heater means, that the heater is installed externally on a wall near the floor as opposed to mounting inside walls or freestanding.

So a hydronic baseboard heater is a unit that uses water to some capacity and is attached to a wall at the floor level at a central position. Heating pipes are run under the floor, which is designed to be used to transfer and emit heat across several rooms or zones. This creates an inbuilt heating system.

Hydronic baseboard heaters evolved from the old hollow cast iron radiators to today’s trendy and beautiful and stylish baseboard heaters.

Hydronic baseboard heaters are long and relatively slim and provide a simple, cost-effective alternative to warm up your home.

2. How does a Hydronic baseboard heater work?

Hydronic baseboard heaters are common in many homes.

However many people do not know the technical aspect of the hydronic baseboard heater.

Basically a hydronic baseboard heater uses the same principle of radiation like the sun to warm up your home.

The baseboard heater contains a heating element surrounded by a metal tube. The metal tube is filled with water.

When the heater is switched on, the electricity heats the element in the tube which then heats the water inside.

The water turns to hot which then disperses the heat to the aluminum fins along the heater tube. This heat up the surrounding air before the air starts circulating throughout the room or heating zone.

The piping system then further channels heat into more rooms.  Heat is sourced from the central baseboard heater, is maintained through flow control valves. In this way, hot water regulates the temperature according to the settings on the thermostat.

convection baseboard heaters are other baseboard heaters that typically resemble hydronic baseboard in terms of design characteristics.

They are placed under windows and are used to warm up small rooms. Unlike hydronic baseboard heaters, convection heaters aren’t able to diffuse the heat produced so they require a fan.

They draw cool air in from close to the floor, through the bottom and project it up and a small fan pushes the warm air out overheated fins on top of the heating unit into the room.

3.     Are hydronic baseboard heaters self-contained?

Hydronic baseboard heaters are self-contained types. You can move the baseboard heater anywhere in the room.

Nevertheless, you can opt for a central location for the baseboard heaters.

4.     How many hydronic baseboard heaters do I need?

You only require one baseboard heater to warm your home with hydronic baseboard heaters. For small rooms or zones use an electric baseboard heater because they are most convenient and are quick to install.

5.     Will hydronic baseboard heaters freeze?

The liquid inside hydronic baseboard heaters is made specially treated water that cannot freeze regardless of the outside temperature. The asbestos material used maintains the temperature of the liquid to continue emitting heat even when the baseboard heater has been turned off.


Technology has allowed us to bring comfort to our homes during the cold months with Hydronic baseboard heaters which give a very convenient and effective source of heat to add comfort to your home.
