Heating Engineer FAQs

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.

can you use hive with an oil boiler?

Smart controls such as Hive are the next generation technology with more and more people now converting their houses into smart homes to control multiple devices in the homes remotely. Smart technology can be incorporated with several household devices such as security, lighting, entertainment and more. But what if there’s an oil boiler installed in your home, can you still connect your Hive with the your heating? Well, simply read on to find out.

The answer to this question is yes, most oil boilers are compatible with Hive and can substitute for either an existing conventional programmer or thermostat. The smart technology works to help derive more benefits from your heating system and they usually come with apps which can be used to control your home’s heating from anywhere with just your mobile device. Hive, however, cannot work to replace the functions of smart oil boiler heating controls to modulate your heating as they only work on an on or off basis. To make use of the modulating technology in an oil boiler, the cost of manufacture would be considerably higher while offering little advantage in efficiency for the home or property owner. Ultimately, this implies that you can’t incorporate smart technology to control the output in a similar way as a gas boiler, but there are still some ways to utilize smart technology with your oil boiler in such a way to boost your efficiency and lessen the energy bills.

Do you want to use your Hive with your home’s oil boiler? We’d advise you get in touch with an OFTEC qualified engineer if you wish to install Hive Active Heating on your oil boiler, as British Gas engineer do not offer this service.

what is a combi boiler?

These great features makes the appliance a very popular choice in UK homes and in fact, it represents more than 50 percent of all new boilers fitted in the UK on a yearly basis.

Most modern and high efficiency combi boilers are usually stainless steel condensing boilers which normally features an in-built secondary heat exchanger to deliver domestic hot water to a home or property. What’s more? When it comes to the heating season or the cold months, the combi boiler will operated as required to heat a structure and offer hot water for showers, sinks as well as other hot water appliances around the house. And when it gets to the warm season or summer months, the combi boiler will only work when there’s a need for domestic hot water which also helps you save more money.

Combi boilers are able to provide domestic hot water in such a way that’s energy efficient due to two primary reasons - the combi units possess a very high operating efficiency and also have a low internal water volume. As a result, in during the hot summer when space heating is not required, you’ll only have to pay to heat up the hot water that you really need and not an entire tank.

Combi boilers also have the following benefits:

✓ Lower costs. Due to the combined nature of the boiler and the lack of tank in the roof space, the installation time and costs are at a minimum.

✓ Saves space in your home as it effectively combines a central heating boiler with a water heater into one unit.

As a result, it requires just a minimal heat from the burner which make the boiler more efficient.
