What Size Of Oil Boiler Do I Need?

When it comes to oil boilers, there are three main types - the combi, system and conventional. Within these types, you’d discover there happens to be a wide range of sizes to choose from. First and foremost, we must note that the size has to do with the amount of energy they offer to your heating and hot water system rather than the physical dimensions.

The rule of thumb is, the larger your house (which implies the more hot taps, radiators and showers), the more powerful (bigger) the oil boiler you’d require. For instance, a four-bedroom apartment with three showers occupied by a family of four will definitely need a more powerful boiler than a a bungalow featuring a single occupant.

It is, however, important to also note that it’s not all about going for the biggest oil boiler. If you decide to choose an oil boiler with a much bigger capacity that needed, not only will you be wasting money on the initial purchase as well as installation, but also lose money operating it. And in a converse scenario, if you go for the cheaper and lower-powered oil boiler in an attempt to save up some money, you’re most likely to end up with tepid radiators while also frequently running out of hot water. Hence, the importance of determining the appropriate size of boiler for your particular household before purchase.

To determine the appropriate size, determining the number of bathrooms, radiators as well as the total number of people living in the property would be a step in the right direction.

Numbers of Radiators Combi System Boiler Regular

Up to 10 24 to 27kW 9 to 18kW 9 to 18kW

10 to 15 28 to 34kW 18 to 26kW 18 to 26kW

15 to 20 35 to 42kW 27 to 40kW 27 to 40kW

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.

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.

If you choose to install an LPG boiler, you’ll need to find an LPG supplier. They’ll deliver fuel to you every time your storage tank runs low. You can even rent a storage tank from them if you don’t want to buy one. Make sure you know who your local suppliers are and where they are based.

Modern oil boilers do not require a lot of maintenance. OFTEC recommends that oil boilers are serviced and inspected every year. This keeps them running as efficiently as possible and will ensure any issues with your boiler are identified before they cause bigger problems. This servicing is also vital because of the increased risk of carbon monoxide leaking from a poorly maintained boiler.

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.

LPG stands for liquid petroleum gas. It’s a by-product of refined crude oil. When it’s put under pressure, LPG turns into a liquid. It’s usually stored in this form. LPG is used as fuel for things like BBQs and camping stoves, as well as central heating.

Your LPG storage tank will need to go outside your property, possibly underground if you have limited space. There are planning rules that restrict where you can put your tank, especially if your property is listed or on designated land. Take a look at our planning permission article to find out more.
