Basics of Electric Boilers

 

How Does an Electric Boiler Work?

The boiler itself is quite straightforward. It can take many different shapes and forms, but the most common is a device that has water running through it and is heated by a heating element, much like a kettle. Long, slender units with a large surface area to heat the water are sometimes seen.

Different Types of Electric Boilers

Electric boilers are classified as classic, ionic, or induction based on their power output, energy consumption, energy performance, energy efficiency, model type (combi or non-combi), and whether they are wall-mounted or floor-standing.

Most electric boilers are combi versions, which means they heat your home’s hot water supply as well as channel hot water via your home’s radiators or underfloor heating.

You may save money on your home heating expenses by installing a low-temperature electric boiler, but you must make sure your house radiators are suitable for this sort of installation.

Advantages of Electric Boilers

In some cases, electric boilers might be helpful. They are really basic pieces of technology that don’t take up a lot of room and can be installed practically any place in a home because they don’t require the flu or a gas line to operate. Electric boilers are almost 100 percent efficient because very little heat is wasted in the process of heating the water.

They’re often easier to install, and they don’t necessitate the services of a Gas Safe engineer. Because of the system’s simplicity and ease of installation, the overall installation cost will be far lower than that of a gas boiler.

Disadvantages of Electric Boilers

Of course, if electric boilers were the greatest option, they would be ubiquitous, but they aren’t. There are several drawbacks to electric boilers, and we will go through them now. At around 30% of the cost of electricity, gas is a far better option. Even if you own a very efficient system, this implies that the cost of heating water with electricity will be significantly greater.

That much is self-evident, but even when comparing electric boilers to other types of electric heating, the electric boiler does not always win. An electric boiler will be more costly to operate compared to infrared.

Electric boilers are likely to find a role in certain homes. They are a basic, easy-to-install solution, but many individuals will find that there are better methods to heat their homes. Infrared, heat pumps and even oil boilers are all likely to be less expensive to run than electric boilers if gas isn’t an option.

If you’re unsure about adding an electric boiler to your home, get guidance from an expert or a local shop. You are also encouraged to check out our Boiler Providers on Linquip for more information to fulfill all of your needs.

Considerations When Selecting an Electric Boiler

What Size Electric Boiler Do I Need?

Most electric boilers are smaller than oil or gas boilers, but it’s crucial to note that in the boiler world, ‘size’ relates to how powerful the boiler is, which is measured in kilowatts (kW). The more kW it has, the more heat and hot water it can generate.

Electric boilers are less powerful than gas and oil boilers, which makes them ideal for smaller homes and apartments. An average gas boiler has a kW rating of 24-35 kW, whereas an electric boiler has a kW rating of 15 kW or less.

A general rule of thumb for electric boiler size is that 1.5 kW is required for each radiator in your home. The size of your space, the height of the roof, and how well insulated the space are all factors to consider, which is why a heating expert is an ideal person to size a boiler for your house. Learn more in the What Size Electric Boiler Do I Need? guide, which will assist you in installing an electric boiler with enough power.

Remember that you will run out of hot water if you install an electric boiler that is too small for your home. It’s also crucial to avoid purchasing an electric boiler that is too large since you’ll be consuming far more electricity than you want and will be surprised by your energy bills.

How Efficient Are Electric Boilers?

An Energy Related Products (ErP) score is used to assess efficiency. This rating assigns a letter grade to each type of boiler, ranging from the most efficient (A+++) to the least efficient (G).

Despite their high efficiency (about 99%), electric boilers often get an ErP grade of D. This is because electricity is generated by burning fossil fuels, which produces twice as much carbon as using natural gas in a gas boiler. Electricity is also considerably more expensive than gas, costing roughly 14 cents per kilowatt-hour vs. three pence for gas. Electric boilers have a lower ErP score as a result of these factors, but they waste nearly little energy during operation.

Solar panels would be even more effective for powering an electric boiler. You will most likely see a reduction in your power costs if you generate electricity this way.

It’s also crucial to look at your hot water tank’s efficiency rating. It’s pointless to have a high-efficiency boiler if the majority of that energy is wasted due to an inefficient water tank. The hot water generated by the boiler is stored in the cylinder for subsequent use. To keep the heat from escaping too rapidly, the tank should be built of high-quality materials and well-insulated.

If you’re concerned about how quickly your tank loses heat, you may buy an extra insulating jacket for it or cover the tank and any hot water pipes that run into it with a blanket. The water should be able to stay warm for at least 24 hours in a well-insulated tank.

Electric Boiler Efficiency and Running Costs

Electric boilers have a high operating cost because most countries generate the great bulk of their power from fossil fuels. This also leads to electric boilers obtaining a D-rating for ErP efficiency, which might be confusing given that they are also classified as 99-100 percent efficient.

Electric Boiler Efficiency

Electricity is a carbon-heavy fuel since it is produced mostly from fossil fuels, which emit a lot of carbon into the atmosphere. So, even if you own an energy provider that uses renewable technology to create power, the electricity is still deemed carbon-heavy. However, as more providers adopt renewable generation, the high ‘fuel factor’ imposed on electricity is likely to decrease.

Running Costs of Electric Boilers

While the operating expenses of electricity are greater than those of gas, as previously said, you will save money in other areas, including installation, not having to schedule an annual service, and overall maintenance expenditures.

 

Factors Should be Considered When Selecting The Best Electric Boilers

Like a standard gas combi boiler, you want your electric boiler to provide consistent hot water and heat, have a long lifespan, and, ideally, help you save energy and money on your heating expenses.

You also want the electric boiler manufacturer to provide a long warranty period so that you won’t have to worry about excessive repair costs if your boiler breaks down.

With these considerations in mind, the following elements should be considered while compiling a list of the finest electric boilers:

  • The boiler maker provides a warranty period.
  • Based on consumer feedback, the boiler brand’s overall reputation.
  • Boiler installers’ reputation
  • Reviews on Trustpilot
  • Awards and honors, such as the Which? Best Buy Awards
  • The quality of customer service
  • The price range of their boilers  
  • Ratings of efficiency

Are Electric Boilers Worth it?

Electric boilers can be a good option for heating water in residential and commercial settings. They offer several advantages over traditional gas boilers or electric resistive heating, including:

  1. Lower Energy Costs: Electric boilers can be up to 3-4 times more energy efficient than traditional electric resistive heating, which means you’ll pay less for your energy bills. They also offer lower operating costs compared to gas boilers, making them a cost-effective option in the long run.
  2. No Emissions: Since electric boilers don’t burn fossil fuels, they don’t emit any greenhouse gases or air pollutants. This makes them a more environmentally friendly option compared to gas boilers.
  3. Ease of Installation: Electric boilers are relatively easy to install, as they don’t require complex plumbing or venting systems like gas boilers do. This can save you money on installation and maintenance costs.
  4. Flexibility: Electric boilers can be used with a variety of heat sources, including electric resistance heaters, heat pumps, and solar panels, making them a flexible option for heating water.

However, there are also some drawbacks to electric boilers that you should consider before purchasing:

  1. Higher Upfront Costs: Electric boilers can be more expensive to purchase and install compared to gas boilers. This may make them less affordable for some consumers.
  2. Limited Capacity: Electric boilers have a lower capacity than gas boilers, meaning they may not be able to handle very large hot water demands.
  3. Higher Power Consumption: Electric boilers consume more electricity than gas boilers, which can result in higher electricity bills if you have high energy usage.

Overall, whether electric boilers are worth it depends on your specific needs and circumstances. If you’re concerned about environmental impact, and energy efficiency, and have a smaller hot water demand, an electric boiler could be a good option for you. However, if you have high hot water demands, a limited budget, or prefer the convenience of gas boilers, you may want to explore other options.

 

What is the Most Energy Efficient Electric Boiler?

There are several types of electric boilers on the market, and some may be more energy efficient than others. However, the most energy efficient electric boiler will depend on your specific needs, budget, and preferences. Here are a few options to consider:

  1. Heat pump boiler: Heat pump boilers are the most energy-efficient electric boilers available on the market. They use a refrigerant cycle to extract heat from the surrounding air or water and can achieve efficiencies of up to 400% depending on climate conditions. While they are more expensive to purchase and install than other options, they offer significant energy savings and can provide heating and cooling.
  2. Condensing electric boiler: Condensing electric boilers are more efficient than non-condensing boilers because they use a condensing mode to extract more heat energy from the hot water output. This makes them more efficient, but they require a condensing mode-compatible heat exchanger, which can be expensive.
  3. Electric resistive boiler: Electric resistive boilers are the least efficient option available, but they are also the least expensive to purchase and install. They use electric resistors to heat the water, which can be expensive to operate.

Ultimately, the most energy-efficient option for you will depend on factors such as climate conditions, space heating requirements, and budget. It’s important to carefully research your options and seek out professional advice to make sure you’re selecting the right boiler for your specific needs.

 

What Boilers Do Plumbers Recommend?

Plumbers often recommend boilers based on their experience with specific brands, product specifications, and their customer’s needs and preferences. Here are some recommendations that plumbers often make:

  1. Condensing boilers: These boilers are more energy efficient than conventional boilers, as they extract more heat energy from the flue gases. Plumbers often recommend condensing boilers to customers who are concerned about energy efficiency and costs.
  2. Heat pump boilers: Heat pump boilers are the most energy-efficient boilers available on the market, but they are also the most expensive. Plumbers often recommend heat pump boilers to customers who have a significant space heating and hot water demand, and who are willing to invest in a more expensive product that will pay off in energy savings in the long run.
  3. Electric resistive boilers: Electric resistive boilers are the least expensive to purchase and install, but they are also the least efficient. Plumbers often recommend them to customers who have a low budget and don’t have a significant heating or hot water demand.
  4. Combi boilers: Combi boilers combine a boiler and water heater in one unit, making them a versatile option for customers who have a small hot water demand. Plumbers often recommend them to customers who are space challenged or who have a low hot water demand.

Ultimately, the boiler that’s recommended for you will depend on your specific needs, budget, and climate conditions. Plumbers often have experience with specific brands and models, so it’s important to ask for their recommendations and weigh the pros and cons of each option carefully before making a decision.

 

Do Electric Boilers Work Well?

Electric boilers tend to work well in most situations, particularly in areas where natural gas is not readily available or where energy costs are high. They are an eco-friendly option that produces no harmful emissions and can be powered by renewable energy such as solar panels or wind turbines.

However, electric boilers do require a significant electricity supply, and the initial cost of installation and running costs may be higher than for other heating options. Additionally, the efficiency of electric boilers can vary depending on the type of system used and the quality of the boiler. It’s important to carefully research different options and consult with a plumber or heating engineer before making a decision.

Overall, electric boilers are a reliable and efficient option for many homes and are often recommended for their environmental benefits and ease of installation. However, it’s important to consider your specific needs and budget when making a decision.

 

FAQs about Electric Boilers

Is Electric or Gas Best for Your Home?

For residences off the grid, electric boilers are an excellent alternative to oil or LPG, and if you want to lessen your carbon impact, an electric boiler is worth considering. If you’re linked to the grid and worried about rising energy costs, you might choose to continue with your gas boiler.

Why Choose a Gas Boiler?

  • Operating expenses will be much greater because electricity is 3-4 times more expensive per kilowatt-hour (kWh) than gas.
  • While an electric boiler does not utilize a fossil fuel like gas to create heat and does not emit carbon dioxide while it operates, the power it requires is normally generated using fossil fuels when an electric boiler works on fossil fuel electricity.
  • Electric boilers are often only suited for small dwellings since they cannot simultaneously serve several outlets.

Why Choose an Electric Boiler?

  • An electric boiler is an excellent alternative if you have solar PV panels installed in your home. You may utilize the electricity you create, lowering your energy costs.
  • Electric boilers have much better efficiency. An electric boiler will provide you with 99-100 percent efficiency, whilst a gas boiler will provide you with 92-93 percent efficiency. An electric boiler might be the answer if you don’t want to waste electricity.
  • An electric boiler, unlike a gas, oil, or LPG boiler, does not emit carbon dioxide when it is in use.

Should I Replace My Gas Boiler with an Electric Boiler?

Replacing your old gas boiler with an electric boiler is not complicated. Heating and hot water pipes are the same and may be adapted/fitted to the new electric boiler. An electric boiler does not require a gas pipe, saving you money on annual gas safety certification.
