How Do Hydronic Baseboard Heaters Work?

The basic principle of best baseboard heaters is that they take in cool air, warm, and then release it back to space. As the heated air is released, more cool air is taken into the baseboard heater. The process goes on as long as the hydronic electric baseboard heater is working. As a result, the heater creates and maintains a warm and comfortable feel in the room in which it is placed.

But there are more details of the way this type of baseboard electric heaters work than merely taking in cool air and replacing it with hot air. The details cover issues such as why the hydronic baseboard heaters are placed near the floor, the different heating methods used, and how they push out the warmed air.

The surface temperature in any given room is not uniform. There are pockets of hot and warm air at any given time. More so, the air near the floor is always cooler than that near the roof. The temperature in between these two zones, the living zone, varies depending on the effect of the heating system.

Naturally, cool air is heavier than warm air. Therefore, warm air automatically rises and is replaced immediately by cool air. This is the reason why the region near the floor in your house is colder than the living zone and that near the roof. Warm air tends to accumulate near the roof.

Also, cool air tends to rush into a room through natural openings like windows and other apertures. As the cool air rushes in, it needs to be absorbed by your electric baseboard heater.

Thus, an electric baseboard heater takes in the cool air that is naturally found near the floor of your house and transforms it into hot air. Also, the heater captures all the inrushing cool air from windows, warms, and then releases it to the entire space in your room.

Some baseboard heaters use the hydronic heating method. A special heating element is sealed in metal fins and then dipped in a heating fluid. The metal fins may be aluminum or copper because they are excellent conductors.

When an electric current passes through the heating element, it is converted into supplemental heat energy. The heat energy is then passed onto the heating fluid. Thus, the heating fluid functions as a form of heat reservoir because it releases the stored heat to the air currents over time. The heated air currents leave the heater and are replaced by cool air currents.

Other baseboard heaters use radiation to provide warmth to the surrounding items in a room. By warming animate and inanimate objects, such heaters ensure that the temperature of a room is maintained within the desirable standards. The warmed objects transfer the supplemental heat to the air within the living zone in a room.

Electric baseboard heaters do not have fans installed in them. The work of the air fans is to maximize the performance of the heaters by pushing the hot air faster into the room. Although hydronic heaters do not have fans, they still effectively move air around spaces according to your requirements.

Given that hydronic baseboard heaters are usually used as supplemental sources of heat, their lack of a forced fan system does not necessarily undermine their performance. They do well by successfully warming all the cool air that naturally accumulates near the floor. As a result, the warm air reaches every corner of the room within the shortest time possible, to the advantage of the people inside the room.

Here is how to troubleshoot a baseboard heater not working

Pros of Hydronic Baseboard Heaters

The following are some of the major benefits that you will enjoy by installing a baseboard heater in your home.

  • Very low installation and maintenance costs. Although you will spend some money installing an electric baseboard heater in your home, this will not be as much as what people spend when mounting electric fireplaces on walls. Furthermore, hydronic baseboard heaters do not have many sophisticated inbuilt systems like other types of heaters. Therefore, you will end up spending very little money on repairing or maintaining them.
  • Quiet operation. Heaters that have inbuilt forced fan systems are noisier than those without. The rapid rotation of the fan is the main source of noise in fans. Because electric baseboard heaters do not have such systems, they operate very silently. Thus, they are suitable for use in bedrooms and other places where silence is required.
  • Quick installation. It is easy to install electric hydronic baseboard heaters than wall-mountable electric fireplaces. Although wall-mountable electric heaters are sold with special brackets for mounting, the process of installing them on walls takes time and needs specialist skills. However, getting a baseboard heater to work is a straightforward and affordable process.
  • Comfortable living. Best baseboard heaters are used to provide supplemental heating in homes. Even if you have a central heating system, the chances are that some spaces in your home will be cold. To make such places warm and comfortable to stay in, you may have to use an electric hydronic baseboard heater. Thus, this type of heaters complements the central heating system to make your home comfortable.
  • Reduced heating costs. Installing hydronic baseboard heaters in your home may be a more economical way of maintaining a warm home than using other types of electric heaters. An electric baseboard heater is an excellent substitute for traditional electric heaters as a form of supplemental heating in your home.

Disadvantages of Hydronic Baseboard Heaters

When compared to other types of heaters, baseboard heaters have certain shortcomings. Here are some of the key disadvantages of choosing baseboard heaters over other types.

  • Constant cleaning. Baseboard heaters require more cleaning than the other types of electric heaters. There are several reasons for this. One, portable baseboard heaters are placed near the floor where a lot of dust and other debris accumulate. Therefore, the heaters tend to accumulate a lot of dust and debris after a short time. If you do not clean your electric hydronic baseboard heater constantly, the dust and debris will accumulate in the fins.
  • Limited heating power. Although baseboard heaters are a good source of supplemental heating in your home, they are not as effective as one would expect them to be. If you install an electric baseboard heater in the living room, it will not provide the required warmth to the spaces adjacent to the room such as hallways. Such spaces will remain cold unless you get another source of supplemental heat for them.
  • Their performance can be easily affected by low-hanging drapes. Typically, low-hanging drapes reach down and cover the baseboard heater. Interestingly, hydronic baseboard heaters should be installed under windows for them to collect and heat as much cold winds as possible. Sadly, low-hanging drapes can easily obstruct the hot air from your baseboard heaters, thus denying you the full comfort of having the baseboard heaters installed in the first place.
  • Costly reinstallations. Although installing baseboard heaters is less costly than mounting electric fireplaces on walls, baseboard heaters can be expensive if not done right. Some cool air enters your baseboard heater through the small gap that remains between the carpet and the bottom of the hydronic baseboard heater. If this, for some reason, is not taken into consideration, then your electric baseboard heater will not work as expected. Reconfiguring the baseboard to create room for the heater to take in enough air may be quite costly and time-consuming.

Things to Consider Before Buying  the Best Baseboard Heaterbest hydronic baseboard heaters

Choosing the most appropriate electric baseboard heater for your house may be difficult. This is because of the large number of brands of baseboard heaters that are available.

Moreover, baseboard heaters differ in terms of technical features and performance. Here are a few things that you should consider when choosing a baseboard heater.


The color of the baseboard heater is an important consideration because the heater will be visible to everyone in your house. You do not want to choose a heater that does not match the color of your baseboard. Doing so may interfere with the general look and feel of your house.

Luckily, many baseboard heaters are either white or cream. These are the colors that are mostly used for baseboards in residential and commercial buildings. Therefore, to get the right baseboard heater for your house, you only need to ensure that its color matches that of the baseboard.

Presence of the Grille

Some baseboard heaters have a grille that contains special louvers. The louvers can be moved to change the direction of airflow. Such baseboard heaters deliver greater performance than those which do not have grilles and louvers.

This is because you can change the direction of the flow of air and ensure that the baseboard heater delivers warm air to the areas in your room that require it most.

Therefore, when choosing a baseboard heater, check if it does have a grille and louvers. This may determine the extent to which you enjoy staying in a room in which the baseboard heater will be installed.


The heating capacity of baseboard heaters is determined by two things: their energy consumption levels and length. Baseboard heaters come in two types: those that consume 120w and others that require 240 volts of energy. The amount of energy consumed is directly proportional to the area that the heaters can warm.

However, the length of the heater also affects its heating capacity. Longer baseboard heaters have higher heating capacities than shorter ones. Therefore, the rule of thumb should be to go for heaters that have the highest wattage and are the longest. This is the case if you need to heat large rooms in your home or office.


Go for baseboard heaters that have built-in thermostats. It is always easy to control such heaters and avoid instances of overheating. You can also use the thermostat to determine how long the heater functions. This will reduce your overall heating costs and ensure that you create and maintain the right environment in your home.

Heating Method

There are two types of baseboard heaters based on the heating method: those that use radiation and those that use the hydronic system and those that use radiation.

Hydronic baseboard heaters have a special heating fluid in which the heating element is immersed. The special fluid acts as a heat reservoir and ensures that the heater generates the needed warmth as required.

Electric baseboard heaters use infrared radiation to warm objects in the room. The heat absorbed by objects within the room is then transferred to the airspace. This creates a very comfortable environment.

Noise Level

Although electric baseboard heaters are generally less noisy than others, including wall-mounted or standalone electric heaters, they nevertheless produce some buzzing sound when working. The noise level of baseboard heaters varies with brand.

Therefore, go for a brand that produces the lowest level of noise. This is particularly important if you intend to use the heater in your bedroom or anywhere else where silence should be maintained.

Intended Use

You can use the baseboard heater as part of the home heating system or as a standalone source of heat in the house. If you use it as a supplemental source of heat, then the goal would be to lower your energy bill. You can achieve this objective by switching off the central heating system at times and relying on the baseboard heater.

If you intend to use the electric baseboard heater as the primary source of heat in your home, then ensure that you match the heating capacity of the brand with the requirements of your house.

If you have second thoughts about heating your home with baseboard, you can try one of the baseboard heater alternatives that are both cost and energy-efficient.
