Boilers are powered by coal, electricity, gas, or oil. Do you, however, require a boiler if you heat your home with electricity.
A boiler operates by heating water, which can be accomplished with electricity. The water then heats the house via radiators. However, if you heat your home with electricity, you do not require a boiler!
Heating the house during the cold season is essential.
Boilers And Electrical Heating
These two are poles apart, but homeowners occasionally require clarification on how they work.
Heating From A Boiler
Boilers provide an easy way to heat your home. But they don’t do it by accident. They contain water, which must be heated before it can emit heat through radiators installed throughout your home.
Depending on the type of boiler, the heated water in the boiler can either turn into steam or be retained. The cooled water or steam is recycled, and the cycle is repeated.
There are several methods for heating boilers, the most common of which are:
Boilers That Run On Gas
These boilers run on gas, which is injected into a combustion chamber. It electrically ignites, heating the cold water in the metal pipes.
When the temperature reaches 180 degrees Fahrenheit, the heat is distributed throughout your property via radiators.
Boilers That Use Oil
They differ from gas boilers in that they use oil rather than gas. The temperature sensor causes cold water to ignite the oil in the fire chamber. An electric charger powers the oil burner, which is filled with highly combustible oil. The heating is maintained once the oil boiler is turned on.
The critical point is that the ignition in these boilers is electrical, but this does not imply that the heating is electrical.
Heating By Electricity
When electrical energy is converted to heat energy, this type of heating occurs. It heats any specific area or space. When you use an electric heater to heat a room, however, electrical resistors emit heat.
The heating element is made up of resistors. They are available in spirals or coils that can be strategically placed under floors, walls, or along walls, or as movable radiators that can be easily plugged into sockets. The air in the space warms up once the coils are sufficiently heated.
The Benefits And Drawbacks Of Electric And Boiler Heating
These two methods have advantages and disadvantages, but that doesn’t mean you’re heating incorrectly. If you still need to decide, you can weigh their advantages and disadvantages.
Heating By Electricity
- Although it is a relatively new heating method, it has several advantages. Heating by electricity:
- Unlike central heating, installation is simple for the majority of users.
- It provides comfortable heating because you can adjust the temperatures and they immediately comply.
- It is easier to maintain because it does not require as much equipment.
- Different types of heaters with no heat leakage are available.
The disadvantages of using electric heating are few but significant. It means you’ll have to find a way around them. The disadvantages are as follows:
- In freezing temperatures, the lack of heating during a power outage is not pleasant.
- High electric bills for adequately heating large homes or offices.
Heating From A Boiler
A home heating system can be difficult to select, but a boiler system has numerous advantages, including:
- Water is a better heat conductor than air, making it more energy efficient. Furthermore, water takes slightly longer to cool than air.
- A boiler’s heat comes from radiators and keeps the floor and lower parts of the room warm, which is beneficial to home users.
- Boilers distribute heat more evenly, keeping you comfortable even in extreme temperatures.

Boilers, like any other type of heating system, have drawbacks. The disadvantages of this one are as follows:
- When it comes to boiler heating, installation and maintenance are both costly.
- Because boilers do not cool space, you will need an air conditioning system.
- It will take some time for a boiler system to start heating, which isn’t always ideal.
- System replacement parts can be difficult and costly to obtain. And if not completed on time, there is a risk of water leaks.
Can Boilers Run On Electricity?
Absolutely! Electric boilers are becoming increasingly popular among homeowners who want to be environmentally conscious. Electricity, like gas or oil boilers, heats the water in the pipes to the desired temperatures.
The heated water circulates through the radiators and is recycled. Electrical boilers are ideal for small flats and homes that are not connected to the local gas supply. Larger homes, on the other hand, will make owners feel the pinch due to high energy bills to keep them warm.
Is A Boiler Like A Furnace?
No, not exactly. Furnaces heat air, and it’s blown into the home via ductwork, grills, and registers. They use all types of fuel, which mixes with air as it burns. Heated air is pushed through the heat exchanger and further on by other heat handlers.
The furnaces are suitable and centrally placed to provide heat for the rest of the house. However, much warm air is lost on its way to the respective living spaces through the ductwork. Some of these furnaces are as old as time, and homeowners find it expensive and cumbersome to do upgrades.
On the other hand, boilers heat water that runs through radiators and heats any living space it’s dedicated to. Some boilers use steam instead of hot water for heating purposes. They can also use all types of fuel for ignition. Boilers, just like furnaces, are pretty common in many homes and aren’t as cheap!
Can An Electric Boiler Replace A Gas Boiler?
Before making the switch, make sure it is worthwhile. Because there is no need to change the plumbing, replacing a gas boiler with an electric boiler is simple.
With an electric boiler, you’ll know why your energy bills are so high. They are quiet, and no maintenance is required. However, before making any decision, carefully weigh the pros and cons because you are in this for the long haul.
The Most Common Electric Boilers
Electric boilers aren’t all that bad, and let’s face it, they’re the only option for some homeowners. To get the best of both worlds, consider these electric boilers that customers say work the best.
- Heatrae Sadia’s Electromax
- THERMAflow
- EK.C Elecktra
- Combi Boiler Comet
- MAC15 Mattira
Some of the most recent electric boilers provide hot water while heating your home with water in radiators. Combi boilers are what they’re called. The boilers mentioned above are just a few of the options available.
What You Should Know About Electric Boilers
If you are certain that you want to use an electric boiler in your home, there are a few things you should consider. Despite the length of the list, three key points stand out.
Power Source
Electrical boilers consume a lot of power. An electric boiler uses a minimum of 12kW, which means it is powered by a 230V single-phase supply. If you require a larger one, use a three-phase power supply with at least 400V.
Radiator Quantity
Large electric boilers can handle more radiators, whereas small electric boilers can only handle a few. Combi boilers of 28 and 32kW, for example, can thoroughly heat a home with 10 to 15 radiators. However, standard boilers with 30kW can heat 15 to 20 radiators.
Flow Rates And Temperatures
It would be beneficial if you considered the hot water temperatures you prefer in your faucets. The flow rate is also not a minor consideration. When installing a combi boiler, this pointer becomes critical.
Is A Permit Required To Install A Boiler?
The size of the boiler and how you intend to heat it will determine whether or not you require a permit. Residential boilers, in general, do not require a permit. Large boilers, without a doubt, necessitate a permit due to their environmental impact. To be on the safe side, contact local agencies about this.
Conclusion
Electrical heating does not require a boiler, but you can use an electric boiler to heat the water. This type of heating is less expensive and easier to install, but it can be costly. Electrical boilers can be effective because they can be easily replaced with gas boilers. However, using electrical energy to power them costs more than using fossil fuels.
