How Do Electric Boilers Work?

Electric boiler are installed in residential, commercial and industrial properties to serve as a reliable source of heat. Unlike other types of boilers that depends on fossil fuel burning to be able to operate, electric boilers are fuelled by electrical energy which ultimately makes it more reliable and powerful compared to its counterparts. This heating option was basically provided for home or property owners who don’t have an access to the main gas supply.

So how does an electric boiler work? Basically, an electric boiler work by heating water. Once heated, the hot water supply is then distributed to various areas across the house or property. In order to achieve the best possible efficiency at the lowest possible costs, new model electric boilers are installed by licensed and professional boiler fitters with the help of a microchip control system. Meanwhile, the microchip control system functions to oversee the management of both temperature level as well as output.

Unlike other types of boilers such as a gas boiler, electric boilers only require minimal service. If you own a gas boiler, it’s crucial to ensure that it’s serviced every single year by a licensed and reliable professional that’s into boiler repair services. During the checks and maintenance services, the gas boilers would need to be checked for possible gas leaks, as well as ventilation poisoning and other problems.

Overall, electric boilers are considered to be one of the most environment-friendly heating system which is more affordable to install in your property than a gas boiler. It represents the most ideal option for homes with gas boiler issues as well as those that are not connected to the main gas supply. What’s more? Electric boilers are also one of the best options for wet central heating and under floor heating.

The simple answer to this question is yes. The Google Nest thermostats are built in such way that makes it compatible with most 24V systems including the older systems. The device is functional with all common types of fuel such as electricity,natural gas as well as oil. However, before purchase it is vital to determine if your thermostat is also compatible. What’s more? The Nest thermostats is also designed to be usable even without the existence of a C wire (common wire) in your home, although a new C wire installation may be required.

Furthermore, Nest Learning Thermostat is compatible with multiple central heating system such as combi boiler systems, air source and ground source heat pumps (heating only) as well as heat only boiler. Now let’s take a look at the Nest thermostat compatibility!

• The majority of the 24 V systems ( including older systems) are compatible with Google Nest thermostat. They can be incorporated with each and every common types of fuel such as oil, natural gas as well as electricity.

• To check the compatibility of your system, you can also check with the Google’s online compatibility checker before purchase.

Condensing boilers are the in-thing when it comes to modern heating systems in UK homes and across the globe for a good reason. This is primarily due to the fact that condensing boilers happens to be highly efficient as it enables the fuel you’re burning to heat up your home go a lot further. Having a new high efficiency condensing boiler rather than an old G-rated non condensing boiler will not only enhance your heating controls, but also save you a lot of money annually. In this article, we’re going to take you through the basics of a condensing boiler. Let’s take a closer look!

If you’re interested in getting a greener and more efficient boiler, you simply can’t afford to look beyond a high efficiency condensing boiler. This is purely due to the fact that these condensing boilers happens to make a better use of the heat they’re able to produce from burning fuels like oil or gas ( in other words, they require less heat from the burner, which makes them a lot more efficient).

So how does a condensing boiler work? Unlike a non-condensing heat-nly boiler, some heat will be wasted in form of hot gases which are released from the flue. Meanwhile a condensing boiler captures some of the heat from these gases and puts them to use for heating up water that’s coming back from your central heating system. As a result, it requires just a minimal heat from the burner which make the boiler more efficient.

You should take note that all new modern boilers are condensing boilers. Therefore if you’re planning to replace an old boiler with a new one, you’ll definitely be buying a new condensing boiler and benefit from all the efficiency and savings that comes with it.

A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.

To ensure your boiler is functioning efficiently and to keep your home warm, it’s important to see that your boiler is serviced on a regular basis by a licensed boiler engineer. Failure to do this can result in sudden boiler breakdown which can be a hard hitting blow to one’s financial power especially when there’s no boiler cover to cushion the blow or totally avoid it all together.

When your boiler is covered, it implies that you’re protected in the event whereby your boiler or it’s controls malfunctions or break. Several boiler cover will include the servicing cost, while some may not so it’s advisable to always go through the details, no matter how small, before entering into a boiler cover agreement. Typically, a boiler cover will cost between £60 to £100 per year and the payment is made on a monthly basis. Various boiler insurance companies have varying cover cost, however, here are the common boiler cover policies:

• Homeserve charges from £13 per month

• EDF Energy costs from £13.29 per month

• British Gas from £12 per month

• Scottish Power from £13.13 every month

• CETRI UK charges from £13.50 every month

• 24/7 home rescue costs from £9.60 every month

• Gorgi Home Plan costs from £6 per month plus 3 months free

• Your repair charges from £9.60 per month

• NPower Boiler Cover costs from £10.92 every month

• SSE Boiler Breakdown Cover charges from £4.95 every month

It’s important to note that sometimes you have the option of adding your boiler cover to your existing home insurance, if you do not want a standalone policy for your boiler cover. In many scenarios, this is referred to as an extra or add on service referred to as “Home Emergency Cover. When compared to the standalone boiler policies, this is usually a lot cheaper as it comes in around £5 per month.

Can You Replace A Gas Boiler With An Electric Boiler?

In the UK, there are about 22 million households that are heated with the use of a gas boiler. However, do not assume that they’re the best type of boiler to install. The fact is, if your house isn’t connected to the main gas supply, the best option is for you to install an electric boiler rather than a gas boiler. So is it possible to replace a gas boiler with an electric boiler? The simple answer is yes. Both heating system options work in varying ways and also with a different impact on the environment.

The gas boiler is able to generate heat with the help of a gas burner. A heat exchanger is linked to the burner and heats the water available in its chamber. The hot water is then supplied to the heating circuit.

However, the thing is that natural gas can actually be more affordable when compared to using electricity to operate your boiler, but they have a negative impact on the environment. This is because gas boilers make use of an odourless, colourless and poisonous gas - carbon monoxide.

Meanwhile electric boilers are powered by electrical energy, hence, no carbon monoxide leak risks. Instead of using gas to heat up water, electric boilers distribute energy to heating elements which, in turn, heats up the water. So thinking about what’s best for the environment, you’d go for electric boilers. However, they’re more costly and are not as efficient as oil boilers.

If you reside in a smaller house that’s not connected to the main gas supply, then you might want to consider installing an electric boiler. However, if you live in a larger house, an electric boiler may not be the best option as they’re mostly designed to generate little quantity of hot water.

How Much Oil Does A Boiler Use?

Are you also interested in knowing the quantity of oil that a boiler consumes to heat up and keep a house warm? Well, you’ll find the answer here. There are so many influencing factors that determines the quantity of oil that’ll be used by a boiler. These factors include the number of hours they’re subjected to use on a daily basis, the boiler’s size as well as how efficient it is. Another factor is how you use your boiler, whether it’s only to provide heating or to provide both heating and hot water will as influence the quantity of oil your boiler uses. As a result, it’s almost impossible to provide an accurate estimate of the amount of oil that an appliance would require to keep running effectively.

In general, to provide a rough estimate, a mid sized oil boiler appliance could make use of up to 3.5 litres of oil per hour when full, but if it’s a large appliance, then it can burn up to 4 litres of oil per hour. However, it should be noted that this is only when the boiler is operating flat out. In the event whereby the water inside the heating system is already hot and the boiler is only working to maintain the level of warmth, much less quantity of oil will be used. And as expected, there will also be times in which your boiler will not be on, and therefore no oil or fuel will b used.

Your home’s size as well as how properly insulated it is can also be a significant influencing factor here. As you would have guess a big home and/or poorly insulated will use up more oil because it’ll be harder to heat up or keep warm. Overall, for some households, 1000 litres of oil will be sufficient to get them through the year, whereas the same quantity may not be enough to get other households through just the winter months.
