How much gas does a boiler use?

Knowing how much gas your boiler is consuming can help you evaluate its efficiency and whether you’re using too much each month. This is especially helpful for allowing you to gauge how much gas to use to keep your costs down. 

Many people are unaware of how to calculate the consumption of gas or electricity in their homes. You can use this post as a guide on how you can calculate the gas consumed by your boiler.

What Affects Gas Consumption?

Several factors affect the amount of gas consumed by a gas boiler. Some of these factors include:

- The size of the gas boiler

- The efficiency of the gas boiler 

- The number of hours per day for which the boiler remains on

The unit of energy that is used to measure gas consumption is kilowatt per hour (kWh). According to studies, an average UK household spends £636 on gas usage annually. 

To find exactly how much gas your gas boiler uses, you can ask your service provider to install a smart meter with your boiler. If you’re located in Redditch, Solihull or Bromsgrove, and you’re looking for boiler repair services, such as installing a smart meter, contact J M Heating and Plumbing.

Why Boilers Consume Excess Gas 

If the unit price of gas remains the same and your boiler has started consuming more gas 

without you using it more than usual, there could be multiple reasons causing excess gas consumption. Some of these issues include the following: 

Thermostat Issues 

Sometimes, the thermostat included with the boiler becomes faulty, resulting in increased consumption. An expert heating engineer can look at your thermostat and advise whether it needs repairing or replacing. 

Faulty Valve

Valves that control the flow of hot water from the boiler to your radiators can stop working properly. This can result in hot water being sent to your radiators when you don't switch the heating on. 

Old Boiler

Old boilers are less efficient and therefore consume more gas. 60% of gas consumption depends upon the efficiency of the boiler. So, you may want to consider replacing your old boiler. It may seem like an expensive upfront cost, but it can save you money in the long run.
