Replacement oil boiler

Our heating system accounts for more than 60% of our annual energy bills, which makes it as important as ever to ensure you have an efficient boiler that’s not likely to breakdown unexpectedly.

As with gas boilers, oil boilers can breakdown or fault at any time, leaving you without heat and hot water for your property. This could end up costing you over £300 in repairs depending on the actual fault.

Oil boilers of more than 10 years of age are prone to suffering a fault of some kind, and the only way to guarantee not experiencing this during the winter is to have a replacement boiler installed.

Oil boilers are often installed into homes that don’t have access to the National Grid’s supply of mains gas. If you do have access to the Grid network then consider replacing an oil boiler with a gas system and you’ll instantly see huge savings on fuel.

Oil boiler replacement benefits

By replacing an old, inefficient oil boiler with a new A-rated model, you’ll:

  • Reduce your heating bills by as much as £300 a year, helping you to escape fuel poverty

  • Heat your home more efficiently, with heat distributed evenly throughout your home. When a new boiler is fitted, your pipes and radiators will often receive a powerflush to improve efficiency

  • Cut your home’s carbon emissions with heightened efficiency, helping the environment to reduce global warming and the Government meet EU targets

Oil condensing boilers

Condensing boilers have grown in popularity throughout the UK because of their high energy efficiency. With a larger flue, more hot gas is retained and used for heat.

The efficiency of condensing boilers is typically over 90%, compared to inefficient systems seeing just 70% efficiency.

Combi boilers tend to be the most popular than condensing boilers and come as either oil or gas heated. With a combi boiler you can heat your home and be provided with hot water on demand. There’s no need for a water storage tank which will save you plenty of room in your loft or airing cupboard.

New Oil boiler FAQs

Can you get oil fired combi boilers?

Can You Get Oiled Fired Combi Boilers?

Absolutely! Oil fired combi boilers are not only a super cool alternative to gas heating, but also offer a cost-efficient means of heating your home. And this is best enjoyed especially if you’re one of the estimated 4 million houses that are not connected to the gas network.

Oil fired combi boiler enables you store fuel close to your property and fill it as required. There many A rated model options available in the market with the modern oil fired combi boilers confirmed to be up to 95% efficient. As a result of their multiple advantages over alternative heating systems, the oil fired combi boiler is expected to increase significantly in the UK. Here are some of the advantages of adding the system to your property.

• Oil fired combi boiler heats up water on demand while also saving a lot of fuel and being super energy efficient.

• Since oil needs more fuel than gas, a great return would be derived from every unit of energy.

• When compared with the other types of boilers, oil fired combi boilers have a considerably lower operating cost.

• A new oil fired boiler typically has a 92% to 95 % efficiency, which is significantly better than the 60% to 70% in older systems.

If you have an idea of how to operate the gas-powered alternative, then operating an oil fired combi boiler shouldn’t be an issue. In a similar way to the alternative, the boiler simply delivers the central heating through the radiators and hot water via your household’s taps.

However, the major difference between the two is the fact that the oil fired boiler needs a regular supply of oil, which is stored in a tank. The hot water supplied by the system is instant as it is connected to the water mains supply.

Do oil boilers need lots of maintenance?

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.

Why should I get an oil fired boiler?

If your property is not connected to a gas main, oil boilers are a great alternative to gas boilers and more efficient than LPG alternatives. They can also be paired well with renewable sources. However, if your property is connected to the gas mains, there is generally no reason to switch to an oil boiler, as you will need to have oil delivered to an extra storage tank.

Are oil boilers as efficient as gas boilers?

Yes. Modern condensing oil boilers are ‘A’ rated and therefore as efficient as comparable gas boilers. They come with the same controls as gas central heating systems, so you can still use a thermostat to control your heating efficiently. Also, oil is more efficient as a fuel source than gas, so you will get more energy per unit of oil. Oil prices can fluctuate, however, so ensure that you find a good supplier.

Do I need to use an OFTEC certified installer?

The Oil Firing Technical Association or OFTEC operate a competent persons scheme to certify installers. It’s always recommended to use an installer with this certification as it proves they have the training and expertise to properly install your boiler and give you realistic advice on the efficiency of your system. Also, OFTEC registered installers offer Workmanship Warranties to protect you if there are any problems after installation.

How much is a new oil boiler?

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.

What is the best oil boiler on the market?

What Is The Best Oil Boiler On The Market?

With a plethora of sizes and models available in the market today, it can be a hassle choosing the best oil boiler. There are 3 main types of oil boilers which includes an oil combi boiler, a regular oil boiler and a system oil boiler. Within these three types, we have a wide range of models and sizes with varying heating and hot water demands.

With tonnes of oil boiler brands out there, the problem is the over crowding on the market with oil boilers that are not only over priced, but also of mediocre quality. From our research, we’ve been able to identify three major bands that are simply outstanding - Warmflow, Grant and Worcester Bosch. However, out of the lots, Warmflow is simply the most efficient and also comes with several qualities such as :

lUK & Ireland’s only AA rated combi boiler

lMarket leading innovation

lEasy and simple to install

l45plus years heating homes

l5 and 7 year warranty available

The oil boiler comes with an outrageous 5 year warranty on their Titanium which when compared to some similar Worcester Bosch Oil boilers is a whooping 3 years difference. Furthermore, the brand also offers a special “out-of-the-box 5-year warranty which enables the warranty to be valid as long as the installation is done by a qualified oil boiler technician. This may, however, seem normal until you realize other brands like Grant, will only honour their 5-year warranty when the boiler is installed only by their accredited technicians.

Warmflow offers an oil boiler to suit every property that is situated off the grid. These includes the modern and stylish U-Series, outdoor-compatible K-Series as well as the quietly efficient B-series which is designed for indoor installation.

What size of oil boiler do I need?

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
