How Often Should You Service An Oil Boiler?

If you have an oil boiler, you probably know the importance of having it serviced to ensure its proper functioning, prolong its useful life as well as ensuring the safety of your home. However, the question that most frequently arises is how often would one need to service the prized hating system? If you’re also looking for the answer to this same question, then you’ve come to the right place. To make sure your oil boiler is running smoothly, safely and efficiently, it should be serviced as often as once in a year. You certainly do want to know the numerous disadvantages of failing to service your boiler. Not only will neglecting your oil boiler service result in possible faults as well as higher energy bill caused by its inefficiency, but can also lead to your warranty ending early.

Therefore, you should ensure your oil boiler is serviced by a qualified heating engineer on an annual basis to make sure it’s running just as it should. This will give you peace of mind knowing you wouldn’t be spending huge bucks on possible repairs and in some cases, replacements.

As a landlord in the UK, it’s a legal requirement to make sure that your oil boiler and flue system is services on a yearly basis in your rental property.

Overall, it’s important to note that failure to service your oil boiler on a yearly basis can give rise to multiple risks. These includes a rise in energy bills, carbon monoxide leak, fault that can cause boiler breakdown as well as an expensive repair or replacement bill.

how much oil does a boiler use?

How Much Oil Does A Boiler Use?

Are you also interested in knowing the quantity of oil that a boiler consumes to heat up and keep a house warm? Well, you’ll find the answer here. There are so many influencing factors that determines the quantity of oil that’ll be used by a boiler. These factors include the number of hours they’re subjected to use on a daily basis, the boiler’s size as well as how efficient it is. Another factor is how you use your boiler, whether it’s only to provide heating or to provide both heating and hot water will as influence the quantity of oil your boiler uses. As a result, it’s almost impossible to provide an accurate estimate of the amount of oil that an appliance would require to keep running effectively.

In general, to provide a rough estimate, a mid sized oil boiler appliance could make use of up to 3.5 litres of oil per hour when full, but if it’s a large appliance, then it can burn up to 4 litres of oil per hour. However, it should be noted that this is only when the boiler is operating flat out. In the event whereby the water inside the heating system is already hot and the boiler is only working to maintain the level of warmth, much less quantity of oil will be used. And as expected, there will also be times in which your boiler will not be on, and therefore no oil or fuel will b used.

Your home’s size as well as how properly insulated it is can also be a significant influencing factor here. As you would have guess a big home and/or poorly insulated will use up more oil because it’ll be harder to heat up or keep warm. Overall, for some households, 1000 litres of oil will be sufficient to get them through the year, whereas the same quantity may not be enough to get other households through just the winter months.
