Baseboard heaters are a great way to provide supplemental heat to an individual room. Because they have a slim profile and lie flush against the wall, they also take up very little space—making them ideal for smaller spaces.

There are two types of baseboard heaters on the market: convection and hydronic. Typical convection baseboard heaters draw cool air over a heating element and emit warm air in return. Hydronic baseboard heaters are pre-filled with water or oil. The internal heating element heats up this liquid and releases warm air into the room. Although hydronic heaters typically cost more than convection baseboard heaters, they tend to be quieter and more efficient.

Most baseboard heaters need to be hardwired to an electrical supply. There are some portable versions available, which can be plugged into a standard 120-volt outlet. Baseboard heaters come in various lengths and offer anywhere from 750 to 1,500 watts of power.

To help you find the model that’s best-suited for your space, we've researched the top-rated baseboard heaters in a variety of categories. Read on for our top picks.

What to Look for in a Baseboard Heater

Convection vs. Hydronic

When compared to a convection model, a hydronic baseboard heater will be slower to heat up a room. Convection baseboard heaters take less time to reach their target temperature, but they’re not as effective or energy-efficient on the whole. While the upfront cost of a hydronic heater is more than a convection heater, you will likely save more on energy bills in the long run. 

Once the thermostat kicks off, convection baseboard heaters don’t stay warm for very long. The internal heating elements and the outer steel casing cool down very quickly. For that reason, a convection heater will likely use more energy to maintain a comfortable temperature. In a hydronic baseboard heater, the heating element will continue to radiate warmth even after shutting off, and therefore provides longer-lasting heat.


To find a baseboard heater that will adequately heat your space, wattage is an important factor to consider. Wattage is a unit for measuring electricity and it determines two things: how much energy a heater will consume, and how much heat it will put out. As a general rule of thumb, you can estimate 10 watts of electric heating per square foot. For example, a 10 x 10 room (100 square feet) will require 1,000 watts of heating power. 

To choose the right wattage size for a baseboard heater, you can do the following calculations. 

  1. Measure the length and width of the room (in feet). 
  2. Multiply the length x the width of the room to get the square footage. 
  3. Multiply the square footage x 10. The end result will give you the estimated wattage required to sufficiently heat a room. 


Wattage goes hand in hand with the length of a heater, which is measured in inches. The longer the length of the heater, the higher the number of watts. Of course there are exceptions, but here are common lengths and wattages of baseboard heaters that you’ll find at big-box home improvement stores. 

  • 24-inch 240-volt heater: 350 watts
  • 36-inch 240-volt heater: 750 watts
  • 48-inch 240-volt heater: 1000 watts
  • 60-inch 240-volt heater: 1250 watts
  • 72-inch 240-volt heater: 1500 watts
  • 96-inch 240-volt heater: 2000 or 2500 watts
  • How do baseboard heaters work?

    There are two main types of convection heaters: convection and hydronic. Although they look pretty much the same from the outside, there are some fundamental differences between the two. The convection process draws cool air into the bottom of the heater. The hater warms up that air and then releases it into a room. Hydronic heaters, on the other hand, contain water or oil within the unit itself. The heating warms that liquid and in turn, heats the air. 

  • What is the best way to clean a baseboard heater?

    Baseboard heaters should be cleaned at least once a year to keep them running smoothly. Before you begin cleaning, be sure to shut off the power and wait until the unit has cooled down. To remove dirt, dust, and other debris from the vents, you can use your vacuum's crevice tool or dusting brush attachments. 

  • How long do baseboard heaters last?

    Since convection heaters don’t contain any moving parts that will wear out, they could potentially last for decades. Hydronic heaters may last just as long, but they require yearly maintenance to prevent corrosion, rust, or calcium deposits. Although you’ll probably pay a little more for the energy a convection heater consumes, it will likely last a bit longer and give you fewer worries than a hydronic heater.
