How to Install Electric Baseboard Heater the Right Way?

How to Install Electric Baseboard HeaterThere are many heating options that you can consider for fighting colder temperatures. Of course, each of them will come with their own sets of good and bad. You need to consider each positive and negative to finally find which particular one fits your criteria perfectly.

If you ask me about it, I’m surely going to think about the people who are short of a budget. Because let’s face it, such confusion is often seen in people who are just starting up with heating equipment. And for starters, budget and basics play the most important part.

One tool that completely outperforms in these two sections is electric baseboards. These are less expensive and also faster to install. So, for today’s chat, I’m going to talk about this amazing heating choice and how to install electric baseboard heater. Let’s Go!

How to Install Electric Baseboard Heater with Wall Thermostat:

From Basics to Main Installation.

Most of you who are looking for ways to install an electric garage heateroften just go straight through the installation.

This is alright to do but to play it safe, you should start with knowing the basics of electric baseboard heater.

What actually the system is and its mechanism for heating are things you should be aware of. So, let’s start with that and then move forward for installing method. However, if you can’t wait, just scroll a little down and know check method right away.

Brushing Your Basics First!

The baseboard heater has a mechanism to offer a radiant heat form. It generally utilizes the natural air convection. This is a method for rising hot air and dropping cold air temperature. So that the area where it sits can have enough heating.

There is usually a thermostat that controls this heating mechanism. It could be on a wall or simply a built-in type.

There are two different types of heaters you can get for your garage. One type offers around the 120-volt system. The other one relies on a 240-volt mechanism.

The more preferable choice by the electricians is 240-volt heaters. This is because the type usually uses lower amperage. Also, it is better in energy efficiency. You can use the heater for a huge garage area. But for the smaller space, a 120-volt heater is more than enough.

In most other heating systems, you’ll find that it usually depends on the motorized air circulation mechanism. But the electric baseboard heaters are different and these utilize the natural airflow for heating purposes.

This is why you can easily have them installed with low cost and simple installation. Now you are ready to understand the installation process given below.

Step 1 – Consider Requirements for Heating.

  • You need to determine what amount of heating is necessary inside your area. This dimension of heating is easy to calculate actually. For every square foot of area, you can go for 10 watts of heating. If you are going for a standard 250 watts heater, it can easily cover at least 25 square feet of space.
  • For a huge area or requirement, you can think about installing high-density baseboard heaters. Installing multiple heaters can also be an ideal solution.

Step 2 – Choose Your Preferable Location.

  • Now you need to choose a particular space inside your garage or basement where there is enough ventilation available.
  • The right type of area for such installation is usually sitting below windows. Make sure there is no obstacle for making furniture or curtains available

Step 3 – Check for Right Wiring.

  • There should be an outlet for electric wiring in the space you’ll install this heater. If there’s no existing system, get a power connection in that place.

Step 4 – Avoid Using Same Circuits.

  • Many people do the mistake of using a similar circuit for thermostat and heater. This can lead to an insufficient amount of volt delivery to your heater. And so, the mechanism won’t be able to heat properly.
  • To avoid such tripping and overloading issues, simply use two different circuits for thermostat and heater.
  • Also, make sure that the thermostat is away from heating source. It needs to be somewhere like behind the doors or dead spaces. Just make sure there’s no connection with heating sources.

Step 5 – Mounting.

  • Now you need to fix a few wall brackets where the installation is going to happen. Simply drill some holes for these brackets. You can use a corded or cordless drill here.
  • Using the right screwdriver, screw every bracket tightly in its place. Gradually move forward to mount the heater in wall.
  •  Once you are done mounting heater, hook thermostat in the right place as well.

Step 6 –Connecting Wires.

  • Most of the electric baseboard heaters use two wiring compartments at each end. So, using different wiring box will give you safer and better results.
  • You can simply make a hole into the wall. Use this hole to bring wire out from one end.
  • The bare wire from electric line will go straight into heater’s green screw. Sometimes the heater comes with a bare wire as well instead of green screws.
  • Now you’ll find a loose wire inside the heater. This will connect the white wire from line. The other loose wire will also attach with black wiring of line.
  • Using the right screwdrivers, attach each wire screws. Make sure these are not too loose or tight. The very same method is applicable for connecting thermostat to electric line as well.
  • Once again, you’ll use this wiring method to attach the baseboard heater with thermostat. And the installation should be done.
  • For the final step, make sure to check before wrapping up. Run the heater and see if it’s functioning correctly.



Don’t set the thermostat to its maximum temperature for quick heating. This is not going to speed up the process at all. Instead, a lot of energy is actually wasted.


You can use insulation instead of fuel. The cost is usually one time compared to fuel that needs constant re-purchasing.


When you use heater for the first time, make sure there is proper ventilation. Windows must be wide open but keep the doors closed.


Usually, the heater might burn off a tiny amount of protective oil that shows visible smoke. But it’s absolutely normal and never happens once you let it burn off completely for around 5 minutes.


Electric baseboard heaters are known for being very inexpensive and painless for one’s wallet. But there’s a simple twist here that you must know before deciding the accessory for your space.

It sometimes comes with a high amount of operational charge. This is suitable for areas where utility prices are low and the temperature is averagely warm. You can go for it if your house is complete energy-efficient and well-insulated. That way there will be no chance of heat loss.


After dealing with a few basics and learning how to install, it’s only right for you to get one amazing electric heater of your choice to set it up. It’s one of the reasonable installation options that suits an insulated area pretty well, almost best.

Just make sure you do the research of safety and fire preventing rules well. And it could be one of the finest decisions for basement or garage heating requirements.
