How much gas does a boiler use?

If you’ve 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 for the first year to be able to compare future years to previous years. 

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

There are several factors to consider when it comes to determining how much gas your boiler is using. One of the easiest ways is by considering the efficiency rating and KwH (kilowatt-hours) of your boiler. 

If you’re feeling 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 out to your home and inspect your boiler. Our services span Whistable, Canterbury, and Herne Bay.

Using KWH For Gas Boiler Usage

A standard UK household has a 35 KW boiler which means it consumes up to 35 KwH of gas. In this case, your boiler should use approximately 210 KwH if the boiler has been running for six hours a day. 

The average amount of gas that a household uses each month is approximately 8,000 - 17,000 KwH each month. 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’s Using Up Your Gas?

Old Boilers  

The efficiency of old boilers is typically poorer compared to newer boilers. If your boiler is 10 years or older, the efficiency could be as low as 60%. New boilers usually work with an efficiency of up to 96%. Therefore, it’s best for gas boilers to be replaced every 10 years. 

Thermostat/Programmer Malfunctions

Programmers ensure that your boiler automatically turns off once a specified temperature has been reached. If your programmer or thermostat isn’t working properly, gas may continue being used which could be the cause for a spike. 

Motorised Valve Issues 

The motorized 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.
