How much gas does a boiler use?

If you have noticed a sudden increase in the amount of gas that your boiler is using, you may want to know how much gas a boiler typically uses as a comparison. Ideally, homeowners should take note of the amount of gas their boiler uses during the first year so that they can compare future years with previous years.

So, how do I find out how much gas my boiler is using?

There are several factors to consider when determining how much gas your boiler is using. One of the easiest ways is to consider the efficiency rating and kWh output of your boiler.

If you are unsure about how much gas your boiler is using, contact us and speak with expert gas engineers. They can answer your questions and help you feel at ease about your gas usage. If they suspect something is wrong, our heating engineers can come to your home and inspect your boiler. Our services span Whitstable, Canterbury and Herne Bay.

Using kWh for gas boiler usage

A standard UK household has a 35 kW boiler, which means it can consume up to 35 kWh of gas per hour. In this case, your boiler could use approximately 210 kWh if it has been running for six hours a day.

The average amount of gas that a household uses each month is approximately 8,000 to 17,000 kWh. This will vary depending on the size of your household and how often you use gas appliances in your home.

It can be difficult to know exactly what has been using up your gas if you use gas for heating and cooking.

What is using up your gas?

Old boilers

Old boilers are typically less efficient than newer boilers. If your boiler is 10 years old or more, its efficiency could be as low as 60%. New boilers usually work with an efficiency of up to 96%. Therefore, it may be worth considering replacing an older gas boiler.

Thermostat or programmer malfunctions

Programmers ensure that your boiler automatically turns off once a specified temperature has been reached. If your programmer or thermostat is not working properly, gas may continue to be used, which could be the cause of a spike.

Motorised valve issues

The motorised valve is responsible for controlling the amount of hot water that goes from the boiler into the radiators. Hot water is allowed to pass from the boiler to the radiators when the valve is open. If this valve is broken, hot water may be sent to your radiators and use up excessive gas.
