What Size Of Electric Boiler Do I Need?

If you’re thinking about installing central heating in your home or property, you’ll be shocked by the plethora of options that’s currently available in the market as regards the boiler type that can be installed. Being a very good alternative to gas boilers or an oil or LPG boiler, electric boilers are here to stay. They usually feature different power outputs which tends to lead to one of the most frequently asked questions about electric heaters - what size of electric boiler do I need? Here, we’ll give you a good insight into sizes of electric boilers available to help you make the right decision.

The importance of getting the perfect size of electric boiler for your home can not be over-emphasized. If your electric boiler size is too small, it won’t be able to provide the level of heat and hot water required. And on the other hand, if it’s too big, it’ll definitely consume more electricity which would be a total waste of money.

To determine the correct size, if you have a wet central heating or water radiators in your home, you’ll need to calculate the boiler’s capacity required to operate them and allow 1.5kw per radiator. To be more accurate, it’s advisable to talk to a professional installer to avoid making a costly mistake. Every professional installer should have an idea of the appropriate size of electric boiler that’ll be needed given your special requirements and home size.

Generally, with a 12k kilowatt boiler, you should be able to operate up to 7 to 8 radiators which is good for smaller properties. For apartments and flats, getting a smaller electric boiler would be the best option.

Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

How Much Is A New Oil Boiler?

An oil boiler is a very useful tool for providing both central heating and domestic hot water to a property by burning oil. As a result, they’re simply one of the most common alternative heating methods used in homes throughout the UK. If you’re not connected to the mains gas network, then it’s a no brainer to depend on another fuel for central heating purposes - oil. Therefore, if you’re looking to get a new oil boiler, you’d need to identify the size and price as there are a plethora of models to select from - all coming in a large array of sizes and prices. We’ve put together some important details about the prices to give you a good insight on the amount you’d have to incur to procure a new oil boiler. Let’s have a look!

Generally, gas boilers are less expensive when compared to the oil boilers. You can get a wide range of gas boilers from a starting price of £500 to £600, meanwhile you’d rarely find an oil boiler less than £1000 in the market.

The lowest priced oil boilers are typically priced starting from around £1000, and the best in class oil boilers normally costs more than £3000.

The rule is, the most expensive oil boiler is typically the largest one. So to have an idea, the bigger it is, the more money you’d have to spend. Oil boiler’s size is measured in kilowatts (kw), which showcases its power. To determine the type of oil boiler that best suits your home, the most significant factor would be the size as a bigger home will require a bigger oil boiler. You have an option to choose between the combi, conventional and the system models of oil boiler.

The size of boiler you need will depend on the size of your commercial property, how many radiators and bathrooms you have and how appliances willl need hot water at the same time. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you.

If you’re thinking about getting a new combi boiler, you may be wondering just how much it’s going to cost so as to start making preparations as soon as possible. However, providing a precise cost for the acquisition and installation of a new combi boiler is simply impossible as combi boiler prices vary greatly in price - usually ranging between £1500 to about £3500 based on the brand of the combi boiler, the insurance or warranty, installation, your location as well as the size and power of the appliance. Due to the fact that combi boilers are compact units which doesn’t need a hot water cylinder or a cold water tank to produce heating and hot water for homes, it’s a very popular type of boiler that’s frequently used especially in the UK.

Combi boilers are also widely known to be the most energy efficient type of boiler because they are able to provide an instant supply of hot water anytime you turn on a tap. Combi boilers particularly perfect for flats and houses where space is limited as they have the ability to deliver instant heating and hot water without requiring any extra parts or components.

In the event whereby you’re about to choose a combi boiler for your home or property, it’s always advisable to compare models as well as prices from only the most reliable and sought after brands across the globe. Depending on the manufacturer, the overall quality of the boilers as well as their prices can differ. However, regardless of your budget, you’ll discover there are a plethora of combi boilers available in the market that’ll also suit your taste.

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.

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

How Do You Bleed An Oil Boiler?

Bleeding air between the oil supply and an oil fired boiler’s burner is a process that’s often required when the system has run out of oil and the burner has stopped working. Upon refilling the oil tank, the air that has been trapped within the oil pipe when empty has to be freed to ensure that the oil reaches the burner and allows it to start again. So how do you go about the process?

First and foremost, it must be noted that it’s always better to be on the look out for the amount of oil in your fuel tank and get it refilled before it runs out. However, if it does run out, you can take the following steps:

• Identify the burner

The burner is a red plastic cover and it’s usually positioned on the bottom part of the boiler (mostly inside the boiler casing). Once identified, inspect it to see if the lockout button is lit red. If yes, simply unscrew and detach the burner’s red case using a flat head screwdriver.

• Identify the oil pump

You’ll find the oil pump on the burner’s left side which is connected to the flexible oil line. Once done, simply locate the 3 inches long hexagonal stem protruding from the pump and with a small threaded plug screwed into the end. Unscrew the plug in just half a turn ( 180 degrees) with a 4mm Allen Key. At this stage oil will be released, do ensure there’s a cloth or rag underneath the plug to grab the oil freed.

• Press the lockout button

This is the next and final step. However it’s also crucial to note that the burner fan will run for about 12 seconds and discharge some oil from the loosened plug which you can grab with a cloth or rag. Immediately you hear a buzzing sound, use the Allen key to tighten the plug. If enough air has been bled, the system will fire. But if not, then you’ll have to repeat the process again.
