An electric combi boiler performs all of the functions of a gas combi boiler, but it does so by using electricity to heat and cool your home. An electric combi boiler can be used solely for hot water, but it frequently suffices for all of your heating needs. This article includes electric combi boiler reviews and a comparison to assist you in deciding whether to go with an electric or gas combi boiler for your home.
There are a variety of reasons why you might want to install an electric combi boiler. It’s possible that your home isn’t connected to the gas mains. Alternatively, the electrical version’s efficiency and environmental qualities may interest you. Another advantage of an electric combi boiler is that it takes up less space than an LPG or oil-powered boiler because there is no need to build a fuel tank.
Whatever your purpose for researching this sort of equipment, the advantages and disadvantages of electric combi boilers will assist you in determining the best course of action.
What is the average amount of electricity used by a combi boiler?
It’s difficult to give a precise figure for how much gas your boiler should use, but you may make an approximation based on the size of your boiler. A boiler with a capacity of 24 kW will consume 24 kW of energy every hour. Your daily usage should be around 120 kWh if your boiler is on for a total of five hours every day.
However, if you’ve recently seen an increase in your gas bill, it’s possible that your boiler is using more gas than it should. To begin, double-check with your provider to ensure that costs have not increased. Keep in mind that newer contracts may include a daily standing charge that must be paid regardless of how much gas you use.
You should also check your bill to see how many kWh it claims you’ve consumed. Remember that you’ll consume a lot more gas in the winter than you will in the summer. If you don’t think this is the case, there are a few more reasons you might be overpaying for gas.
Is electricity used by gas combi boilers?
Boilers consume very little electricity, yet it is still required to perform essential operations. Electricity will be used to keep your home warm and supply hot water through display screens, back-lighting bulbs, and smart thermostats.
The boiler must be ignited with electricity. This is the ignition that fires the gas to create a flame, if you’ve ever heard your boiler make a click when it starts up. This task will consume a very small quantity of electricity, therefore it shouldn’t be particularly expensive.
The central heating pump and the boiler fan are the two primary components of a gas boiler that consume the most electricity.
A gravity-fed system may be used by some older boilers. These systems use gravity to circulate water around the radiators, eliminating the need for a separate pump. Many modern heating systems, on the other hand, will rely on a central heating pump. These devices require energy to operate, but only when the pump is turned on for the first time. This means they won’t use a lot of electricity and won’t need it for the duration of their operation. This could help you save money as well as energy.
The majority of central heating pumps found in household boilers consume roughly 60 watts of energy, though this varies depending on the size and speed of your pump. This is less than the energy required to bring a kettle to a boil.
It’s critical that your central heating pump is the right size for your house. A pump with insufficient horsepower may not be able to push enough water through your radiators. A pump that is too large may consume too much electricity. Variable-speed central heating pumps are common. Increasing the speed, on the other hand, will not necessarily result in your rooms heating up faster. As a result, more electricity will be consumed, and the heating system’s efficiency will be diminished. It’s best if you don’t touch your central heating pump.
Another aspect of your boiler that uses a little amount of electricity is the boiler fan. Some people believe that a fan is utilized to cool down the components in a boiler, however this is not the case. Its purpose is to exhaust flue gases to the outdoors.
Before your boiler ignites, you must turn on the fan. This is a safety element that ensures that all gases produced during combustion are expelled from your home. Your boiler will not ignite if the fan fails to turn on. The printed circuit board (PCB) that controls all of the boiler’s electronic components detects problems like these. This gadget is responsible for determining whether or not the fan is turned on.
If the fan on your boiler isn’t working properly, it could be due to a problem with the electrical connector that supplies the fan with power from the mains. This will result in a fault code of FC for Viessmann boilers. This could indicate a malfunctioning gas valve or the need to inspect the fan and fan cables.
Check the timer if you’ve recently had a power outage and your boiler doesn’t seem to be coming back on. After a power outage, most clocks, including those on your cooker, may reset, and it may be as simple as reprogramming it manually. Check the instruction manual if you’re not sure how to accomplish it.
Are combi boilers electric?
A decent boiler may make a great difference in a family, especially during the chilly winters in the United Kingdom. There are many various types of boilers, but combi boilers are an effective and quiet method to heat your home and provide hot water at the same time.
If you need to replace your old gas or oil boiler, an electric combi boiler is an excellent option. An electric combi boiler has various advantages, including:
- It is a more environmentally friendly and non-polluting solution because it does not emit any gas into the atmosphere.
- It is available in a variety of sizes and can be stored in your kitchen or laundry room.
- Because of the low installation and maintenance expenses, combi boilers are significantly less expensive than gas or oil boilers.

Is it necessary for a boiler to be powered by electricity?
We’d like to dispel one of the most common misconceptions about furnaces that we still hear: a gas furnace can provide heat in the event of a power outage. This appears to make sense on the surface. A gas furnace generates heat by burning natural gas, which is then circulated through the ventilation system. In this regard, it’s similar to an old-fashioned stove: there’s no need for electricity, just plain old heat from a different power source.
This, however, is not the case. Your gas furnace will not operate if it does not have access to electricity.
How much does it cost per hour to run a combi boiler?
You’ll pay around 2.4p per kilowatt-hour if you use mains gas. This means that running a 35 kW boiler for an hour will set you back roughly 0.84. LPG, on the other hand, can be a little more expensive. An LPG boiler costs roughly 7.6p per kilowatt-hour to run. To run a 35 kW LPG combi boiler, you’ll have to pay around 2.66 per hour.
Is a combi boiler powered by natural gas or electricity?
The most common form of boiler in the UK is a combination boiler, also known as a combi boiler. You won’t need a cold water tank or a hot water cylinder because they heat hot water directly from the mains when you turn on a tap. They can be a cost-effective option because you don’t have to store hot water and simply heat what you need.
Cons
- It may take a few seconds for your water to heat up, especially if the boiler is located far away from the faucet.
Good for: Homes with limited space or where there aren’t many people using hot water at the same time.
What in a house consumes the most electricity?
The breakdown of energy use in a typical home is depicted in today’s infographic from Connect4Climate.
It displays the average annual cost of various appliances as well as the appliances that consume the most energy over the course of the year.
Modern convenience comes at a cost, and keeping all those air conditioners, freezers, chargers, and water heaters running is the third-largest energy demand in the US.
One of the simplest ways to save energy and money is to eliminate waste. Turn off “vampire electronics,” or devices that continue to draw power even when switched off. DVRs, laptop computers, printers, DVD players, central heating furnaces, routers and modems, phones, gaming consoles, televisions, and microwaves are all examples.
A penny saved is a cent earned, and being more energy efficient is excellent for both your wallet and the environment, as Warren Buffett would undoubtedly agree.
How does a combi boiler get its energy?
The most common type of boiler marketed in the UK is the combi boiler. Because there is no need for a hot water storage cylinder, water is heated instantaneously when a hot tap is turned on, making them ideal for houses with limited space.
In one small housing, a combination boiler combines a water heater and a central heating boiler. The boiler will fire up if the room thermostat gives a signal to do so because the temperature has dropped below the set point, allowing heat to be injected into the central heating system. The boiler will’modulate,’ or turn itself down, once the thermostat set point is reached, keeping the heating at the proper temperature and saving energy.
When someone turns on a hot water tap, a valve inside the boiler diverts the heat into the household hot water supply, producing hot water until the tap is turned off, at which point the valve returns to the ‘central heating’ position, delivering hot water until the tap is turned off. Heat can be delivered to either the central heating system or the hot water taps, but never both.
Combi boilers need enough mains water pressure to give a satisfactory water flow rate; if the mains water pressure is too low, hot water will only trickle. A System boiler may be a better alternative for you if your mains water pressure is low or you have more than one bathroom.
It’s also crucial to make sure the boiler’s heat output is adequate for your needs. Combi boilers produce two types of heat: one for domestic hot water and another for central heating. Because producing hot water requires more effort and hence more heat than heating radiators, the hot water output is usually what defines your boiler option.

- The boiler casing contains everything needed to supply heat to your radiators or hot water to your taps, so you won’t need to make room for a hot water storage cylinder or a central heating pump ideal for houses with limited space.
- Because a combi boiler does not require a tank in the loft or a hot water storage cylinder, it requires less plumbing, which saves time and money during installation.
No, because a combi boiler only heats water when a tap is switched on, therefore no hot water is stored. Here’s a look at our selection of combi boilers.
Yes, we have dedicated LPG combi boiler models so that residences off the mains gas grid can benefit from the excellent efficiency of our combi boilers. Here’s where you can see our LPG combi range.
When the Building Regulations were revised in April 2018 (often known as Boiler Plus), every boiler installation now required a timer and controls, as well as additional energy efficiency measures for combi boilers.
Is it true that combi boilers are less expensive to run?
Energy efficiency is the most popular reason for users to move from traditional to combi boilers. According to the Energy Saving Trust, replacing your 10 to 15 year old boiler with an A-rated combi boiler can save you up to 40% on your energy cost.
