Electric combi boilers are more expensive to run than gas boilers
The high running costs of electric boilers are also influenced by other factors such as the size of the boiler, the insulation of the home, the local climate, and the electricity tariff. For instance, the average electric combi boiler uses about 2-6 kilowatts per hour to heat a medium-sized home, which can result in monthly costs of around £216-£648 assuming daily use. However, these costs can be reduced with efficient usage and good home insulation.
In contrast, gas boilers have a wider range of models that can accommodate different energy outputs and central heating requirements. They are also better suited for larger homes with multiple bathrooms and higher hot water demands.
While electric combi boilers have higher running costs, they offer several benefits that may make them a preferable choice in certain situations. They are highly efficient, with some models reaching up to 100% efficiency, and they are ideal for smaller homes or flats, especially those off the gas grid. Electric boilers are also easier to install, have a simplified maintenance protocol due to fewer moving parts, and can be paired with renewable energy sources like solar panels to reduce energy costs.

Electric boilers are 100% efficient but electricity costs are higher
Electric boilers are highly efficient, reaching 99-100% efficiency by converting all electricity into heat for direct use. However, electricity costs are higher than those of natural gas, making electric boilers more expensive to run.
The high efficiency of electric boilers is due to the elimination of a combustion process, which can introduce stress and decay in gas boilers. This results in a longer lifespan for electric boilers compared to conventional gas boilers. Additionally, electric boilers have fewer moving parts, which generally means less wear and tear over time and simplified maintenance.
Despite their high efficiency, electric boilers have higher running costs due to the higher price of electricity. In the UK, electricity costs are approximately four to five times higher than gas per kilowatt-hour (kWh). As a result, an electric boiler will likely cost more than double that of a gas boiler, even with the higher efficiency of converting electricity into heat.
The cost of running an electric boiler is influenced by various factors, including the size of the boiler, the insulation of the home, the local climate, and the electricity tariff. The number of radiators in the home also plays a role, as a larger boiler is needed to accommodate more radiators, impacting the cost. Additionally, the temperature setting of the boiler should be considered, as setting it higher than necessary can lead to increased energy consumption.
In summary, while electric boilers offer high efficiency and simplified maintenance, they are more expensive to run due to higher electricity costs.

Installation is simpler and they're ideal for small homes
Electric combi boilers are highly efficient, making them ideal for smaller homes. They are also a good option for flats and properties off the gas network. The installation of electric boilers is much simpler as they can be installed anywhere and have fewer components. They are also more compact than traditional gas boilers, saving space.
The cost of installing an electric combi boiler can vary depending on factors such as location, manufacturer, and unit size. Installation costs can range from £650 to £2,500, with an average cost of £1,850. The price of the boiler itself can range from £1,500 to £5,000, depending on size and features, with smaller models generally being cheaper.
The running costs of an electric combi boiler are higher than those of a gas boiler due to the higher cost of electricity compared to gas. The average 1-2 bedroom home can expect to pay around £2,000 per year to run an electric combi boiler. The cost of running an electric boiler for 70 hours per month can be up to £285.60, compared to £86.52 for a gas boiler. However, electric boilers are more efficient, with some models reaching 99-100% efficiency, while gas boilers are only around 90-92% efficient.
To reduce the running costs of an electric combi boiler, it is important to consider factors such as the size of the boiler, the insulation of the home, heating requirements, and the electricity tariff. Regular maintenance and sensible temperature settings can also help to reduce costs and environmental impact.

Maintenance is simplified due to fewer moving parts
Electric combi boilers are simpler to maintain than their gas counterparts due to having fewer moving parts. This design aspect results in reduced maintenance requirements and increased ease of upkeep.
The simplified maintenance process for electric combi boilers is attributed to their fundamental operational differences compared to gas boilers. Electric boilers do not require a flame to heat the water, as they use electric heating elements instead. This eliminates the need for several components typically found in gas boilers, such as a burner, heat exchanger, and flue.
The absence of these parts in electric combi boilers significantly reduces the number of potential failure points. There is no risk of issues like a faulty burner, blocked heat exchanger, or flue problems, which are common sources of maintenance headaches in gas boilers.
With fewer moving parts, electric combi boilers offer a more reliable and low-maintenance option. They are less prone to breakdowns and malfunctions, which can save time and money on repairs and maintenance checks. This makes them an attractive choice for those seeking a hassle-free and efficient heating solution.
Additionally, the lack of combustion in electric boilers means there is no production of harmful by-products, such as carbon monoxide, making them safer and eliminating the need for annual gas safety checks. Overall, the simplified design and reduced number of moving parts make electric combi boilers a more straightforward and low-maintenance option for homeowners.

They may be worth the cost for certain features and long-term savings
Electric combi boilers have higher running costs than gas boilers due to electricity prices, making them less cost-effective in the long run. However, they may be worth the cost for certain features and long-term savings.
Firstly, electric boilers are highly efficient, with some models reaching efficiency levels of 99-100%nearly all the electricity is turned into heat, while a gas boiler loses a portion through exhaust. Electric boilers are also better for smaller properties with lower energy demands and fewer radiators. They do not require annual servicing and are not affected by gas prices.
Secondly, electric boilers have a simplified maintenance protocol due to their fewer moving parts compared to traditional gas boilers. They are also known for having longer lifespans than conventional gas boilers, as they do not have a combustion process that can introduce stress and decay.
Thirdly, electric boilers are compact, energy-efficient, and easier to install compared to traditional gas boilers. Installation fees should be considered when calculating the total cost, and these can range from £650 to £2,500. Electric boilers can be installed almost anywhere and are ideal for small homes, flats, or properties off the gas network.
Finally, while electricity is more expensive, you don't always have to rely on a supplier. Instead, you could turn to renewables to generate your own electricity. Solar PV panels turn solar energy into electricity, which can then be used to power your boiler. Therefore, during daylight hours, you could be heating your home for free.
In conclusion, while electric combi boilers have higher running costs, they offer several features and long-term savings that may make them worth the cost for some homeowners, especially those with smaller properties.
