CHOOSING TO HAVE AN OIL BOILER

New Oil Boilers Operation & Installation

How does an Oil Boiler work?

An oil-fired boiler heats water and pumps it through radiators and to hot taps, in the same way as a gas boiler. While gas is piped straight into the house via the mains connection, oil has to be stored in a tank on the property which is connected to the boiler. You will need to have oil delivered regularly

How much does a new Oil Boiler cost?

This depends on several factors, depending on the size, make and model an oil boiler, the parts required, including the flue, system filter, alteration of pipework and whether it is in an indoor or outdoor, if a new oil tank is required etc the cost can vary considerably which is why we come and assess fully your individual requirements and we provide a no obligation quote.

Can I fit a new Oil Boiler myself?

You could, if you have the know-how, but DIY boiler installation is risky. Without certification by a “competent” OFTEC (Oil-Fired Technical Association) installer there may be problems with insurance, and if you have made any mistakes with the fitting there could be a safety hazard.

REPLACING AN OIL BOILER

The Lifespan of a New Oil Boiler

How long does an Oil Boiler last?

On average oil-fired boilers that are well maintained and regularly serviced should last up to 20 years. Once your boiler reaches that age, or close to it, it won’t be working as efficiently as newer models, will be requiring a lot of repairs and attention, and be gobbling up fuel, so it is best to replace it with a new one.

How efficient are new oil boilers?

Oil is an efficient fuel, with most of the modern oil boilers offering more than 90% fuel efficiency, so you are getting the most heat for your money. They become less efficient as they age. Oil condensing boilers are particularly fuel efficient.

Are Oil Boilers going to be Banned?

The Government has pledged to reduce CO2 emissions to zero by 2050, and part of the strategy to end the use of fossil fuels involves banning the installation of oil boilers in new build homes from 2025. Oil boilers in existing properties are not affected, and it is likely to be decades before the millions of homes that use oil boilers are compelled to use alternative sources of heating.

Are there different types of oil boilers?

Just like gas boilers, oil-fired boilers come in three types – combi, system or regular. Combi oil boilers are a convenient compact unit for both hot water supply and heating in small homes. Regular oil boilers store hot water in a separate cylinder for dual purpose use of central heating or tap water, while system oil boilers are a closed system, using a separate hot water cylinder in a similar way to regular boilers.

How much does an Oil Boiler cost to run?

A number of factors affect the cost of running an oil boiler, not least of which is the fluctuating price of oil (which, remember, includes the cost of delivery). Consumer group Which? estimates the average annual cost of heating oil to run both heating and hot water is £830, based on a consumption of around 17,000 kWhs worth of heat a year.

What are the advantages of oil-fired central heating?

Oil is a good option for heating if you live away from the mains gas supply, with a relatively low cost compared to electricity. Oil is safer than gas in that it doesn’t produce carbon monoxide and although flammable, is not prone to explode. When oil prices are low you can stock up, and there are no supplier contracts, so you can shop around.
