15 Differences Between Electric Boilers and Oil Boilers

It’s been around for centuries, but boilers have undergone a major design shift. It wasn’t safe or efficient to utilize the original coal-burning furnaces in a residential setting. Due to their practicality and certain advantages over coal-fired models, they were eventually replaced by oil-fired models. Electric boilers are more recent variants that don’t use gas or oil to generate heat; instead, they connect into an electrical outlet. Because of their large size, electric boilers are often found in residential complexes exclusively. Compared to oil boilers, we will look at electric boilers in this post.


Using gas or oil to heat water is safer than using electricity, which is very combustible. Modern oil boilers, on the other hand, contain safety systems that may assist avoid issues before they arise. As an example, if the boiler’s pilot light goes out, it will automatically shut down. You may also keep an eye on your boiler’s oil level to make sure it’s running properly. These safety precautions may not be present in electric boilers, but they are just as safe.


Electric boilers do not need combustible fuels like oil or gas since they are powered by electricity. Unlike oil boilers, electric boilers don’t emit combustion gases that need to be vented out of your house, making them more efficient. Due to the need for power to run an electric boiler, certain electric boilers are less efficient than some oil boilers.


Because oil is a less costly fuel than electricity, oil boilers are more cost-effective than electric boilers. Propane or diesel might save you money on an oil boiler for your home’s heating needs. The only drawback is the additional cost of utilizing grid energy. If you’re curious about how much energy it takes to heat a room, have a look at this article.

Uncomplicated Setup

Due to the fact that many electric boilers do not need any specific venting, they are simple to install and can be placed almost anyplace. You’ll need a venting method for an oil boiler, most often via your roof or wall. If your oil boiler is an older type that does not employ contemporary technologies, you may require the assistance of a professional boiler installation like Easy Boiler Company.

Extensive Usability

When taken care of correctly, electric boilers may survive for decades. To avoid a breakdown in the dead of winter, make sure you do routine maintenance on your vehicle. Oil boilers, too, may survive a long time provided they get regular maintenance. In order to ensure that your oil boiler is running properly, you should have it serviced by a professional at least once a year.

Intuitive to Use

Using a smartphone app, you may remotely regulate an oil boiler, making them more convenient than electric boilers. Energy savings are possible when the heater can be turned on or off from your phone. Thermostats, which are convenient and simple to operate, may also be used to regulate electric boilers.


Unless they are occurring on a regular basis, odd sounds coming from an oil boiler are not a reason for alarm. However, compared to oil boilers, electric boilers may be less loud. If you’re going to acquire an electric boiler, be sure it doesn’t make you feel like you’re living in a laundry while it’s operating.

Instantaneous Heat Generation

It will take a long time for an oil furnace to heat your house since the fuel needs to be burned before any useable products can be made from it. Heating components in an electric boiler are powered by electricity, so your property may feel warm even if there is no hot water or if you flip on the switch shortly before you enter. The expense of running oil-filled radiators is well-covered in this article.

To put it another way, the resale value

Oil boilers provide the most resale value if you’re looking to upgrade your current boiler. For this reason, oil boilers will be in great demand when it’s time to sell since so many people use them in their homes. For this precise reason, electric boilers do not have a high resale value.

More Pollutant-Free Air

If there is an inside leak or a problem with the furnace, surplus gases from oil heaters might be released into the air, posing a serious health risk. Carbon monoxide, a gas produced by oil furnaces but undetectable without the right tools, maybe lethal in high concentrations. Electric boilers, like oil furnaces, create trace amounts of these hazardous compounds, albeit in far lesser proportions.


If you have an electric boiler, you must use a neutralizer on an ongoing basis to keep your water pipes from corroding. Because oil furnaces are not physically linked to anything, they do not corrode.


When purchasing an oil furnace, keep in mind that it will take up more room than an electric boiler. To make place for the oil furnace, you may have to clear out rooms or reorganize your house. Putting an electric boiler outside may not need as much room as putting an oil furnace outside, since electric boilers are often smaller than oil furnaces.

Ownership Cost

You save money over time by using a lower thermostat setting when you have an oil furnace since it is cheaper to fuel high BTU burns all winter long. Because they have to work so hard to warm your home, electric furnaces deplete batteries more rapidly. When making the move to an electric boiler, you may want to consider swapping out your solar panel system with more batteries or ensuring that you have enough on hand.

Time Required for Setup

As a result of the wiring through the walls, electric boiler installations might take longer than oil boiler installations. Because oil furnaces don’t have any pipes or hoses hooked directly to them, the installation process is substantially faster. If you do decide to install an oil furnace in your house, make sure you have enough fuel on hand at all times so you are prepared for another frost during the winter season.


Because you don’t have to worry about constantly refueling an oil furnace, they are far more convenient to use than gas furnaces. When the power system is down, it might cost more to run electric boilers, which use little quantities of energy all day. This might be a problem for your house in the future, therefore a generator or additional batteries may be necessary.

The Ending

Having an electric boiler in your house eliminates the danger of carbon monoxide poisoning since no fuel is needed. As a result, you and your family won’t be exposed to any gases that might harm or even kill you if breathed. You shouldn’t use an oil furnace to heat your house if you have little children. In contrast, an electric boiler produces hazardous gases far less often than an oil boiler does.
