Oil Boilers

Are external oil boilers good? | Boilerhut

We provide oil boilers nationwide

Do you live in one of the 4 million homes that don’t have access to natural gas? Or, would you prefer not to use gas?

Installing an oil boiler is a great option. It gives you independence from national grid gas pricing. Plus, you have control over when you refuel your oil tanks, meaning you can stock up when prices are at their lowest.

Oil boilers are just as efficient as gas boilers, but they tend to be more expensive to buy and install. This is mainly because there are fewer of them. It’s the same with servicing. Another great advantage of oil boilers is that they are often available in an external model. This allows you to move the boiler outside your home, reducing noise and freeing up space.

At Boilerhut, we offer comprehensive oil boiler installation. Our network of oil boiler engineers installs across the UK mainland.

How does an oil boiler work?

Exactly the same way as natural gas and LPG. The burning fuel heats water for heating and showers or taps.

Except that the fuel is oil, which must be stored locally. You will need a tank for the oil somewhere in your garden. Often, they are next to outbuildings, sheds or garages.

Choosing an oil boiler?

Our journey with you starts as soon as we receive your quote details. The system will work out the boiler’s power you require based on the number of radiators and bathrooms you have.

We will then call you to fully understand the nuances of your home, heating and hot water requirements. Every home is different, and every quote will need adjusting to ensure nothing is missed for the oil boiler installation.

Boilerhut has over 12 years of experience with oil boilers. And our engineers’ combined experience is much higher. We have partnered with Navien and Grant for oil boiler installations and can offer Worcester Bosch boilers too.

We only work with premium brands that offer great products. Navien, for example, only uses stainless steel heat exchangers. This ensures they’re the best quality and will remain efficient for the boiler’s life, unlike aluminium heat exchangers, which lose efficiency over time and corrode easily.

We don’t need to visit your home to do a survey. Instead, we will do everything on the phone until you agree to buy a boiler with us. Then, a final survey is carried out by the installer before any work is carried out.

Do I need a new oil boiler?

Like all modern boilers, oil boilers are built to last 10-15 years. However, they need to be well maintained with services every year and good quality fuels.

But, like all boilers, eventually, it will stop functioning or working completely. For example, you may be having frequent breakdowns. Or a rise in oil usage. Parts may become rarer, or the boiler isn’t heating your home any more.

So if it’s not working or you think it’s close to stopping working, get a quote with Boilerhut today. Sometimes we can install boilers the next working day.



How much does an oil boiler installation cost?

  • The average cost of a premium oil boiler installation for a 3-bedroom house is £4,978.
  • On average, oil boiler installation, with a new tank will cost between £5,000 to £8,000.

This is based on a combi boiler to combi boiler swap in a home with 12 radiators and one bathroom. But remember, all quotes are unique. As is your home. Get a quote online now to get your personalised oil boiler installation quote.

If you are running an old oil boiler and paying around 65p per litre (as of 16/01/2024) and spending £1200 on your total oil spend, switching to a new condensing oil boiler with over 90% efficiency could save you 30 to 40% on your annual oil consumption, roughly £400 to £500.

Frequently asked questions

For an oil boiler installation at your property, you will require an oil storage tank.

There are three main types of oil boiler tanks:

  • Single Skin: suitable for installation in a reinforced concrete or masonry bund
  • Double Skin: predominantly used for commercial underground applications
  • Integrally Bunded: used above ground and within buildings

Oil storage tanks are usually made of steel or polyethylene. They can be supplied in a range of shapes and sizes to suit the site requirements. If you don’t already have an oil storage tank, we are able to assist you in choosing the most suitable type and size for your property.

For most homes, an oil storage tank between 1000-2500L will be suitable. Oil storage tanks are usually fitted with a device that will warn you when the tank contains low levels of oil.

When installing an oil storage tank, it is important that the regulations are followed for safety and environmental reasons.

As oil engineers with vast experience, this is something that we will assist you with during your oil boiler installation.

Yes, fumes from oil burning can be dangerous, particularly if they contain carbon monoxide (CO) and other harmful substances. When oil is burned in a boiler, it should ideally combust completely, producing water vapor and carbon gases. Carbon monoxide, a colorless, odorless, and highly toxic gas is also produced.

Flues bring air into the boiler as well as provide an exhaust route to the outside world.

No, not anytime soon anyway. With so many homes off-grid and so many unable to be retrofitted with air source heat pumps oil or LPG is usually the only fuel available. Electric boilers are expensive and usually require an expensive 3-phase supply.

They tend to be more expensive to run than gas because of the price of the fuel being used. Modern oil boilers are highly efficient and burn with a blue flame. Blue flame means the fuel is vaporised and burns a lot more cleanly and efficiently than older yellow flame systems.
