How Much Gas Does a Boiler Use per Hour?

Not everyone keeps track of their monthly gas and electricity usage. To be sure your energy supplier hasn’t overcharged you or undercharged you, it’s always worthwhile to compare your use and bill. For opportunities to find a new energy supplier and ways to lower your gas bill, check out this page.

What Does It Cost per Hour?

Kilowatt-hours (kWh), a common unit of measurement, are the most accurate way to gauge gas use. It might be challenging to determine your typical monthly energy cost because of a variety of factors, including your location, consumption, and even how you pay for your energy.

To determine how much energy is used to heat your home, it is essential to convert the figure to kWh.

Main Gas

It will cost you roughly 2.4p per kilowatt-hour for mains gas. Running your gas boiler for one hour will look something like this:

  • 24 kW gas boiler will cost you £0.57
  • 28 kW gas boiler will cost £0.67 per hour
  • 35 kW gas boiler, running it for one hour will cost you about £0.84.

LPG

LPG will cost you more since the gas is a little pricier. An LPG boiler costs about 7.6p per kilowatt-hour to operate. The cost to operate your gas boiler will be:

  • 24 kW LPG combi-boiler will cost you £1.82 per hour
  • 28 kW LPG combi-boiler will roughly be £2.12 per hour
  • 35 kW LPG combi boiler is about £2.66 per hour

Factors Affecting Consumption

The average gas consumption per hour depends on several factors. The following might be the problem if you find that your boiler is using more gas than usual:

Boiler Size

The larger a boiler is, the more water it can heat at any given time. This means that you’ll use more energy to heat your home when there’s plenty of hot water inside it than when there isn’t much left in there.

Weather

As the winter progresses, your boiler and heating system are likely to be under more stress. This is especially true if you suddenly find yourself using it a lot after the summer hiatus. It is only natural that boiler pressure will increase as winter approaches.

The colder things are outside, the more energy it takes to heat them. A sudden drop in temperature might mean that you have to turn on your heating earlier than usual if you haven’t set up timer switches or other automated systems yet.

Energy-efficiency of Boilers

If your boiler is more than 10 years old, it’s probably not as energy efficient as it could be. This means you could be paying more for your energy bills than you need to.

The good news is that there are many new boilers on the market which are much more efficient than their older counterparts. The bad news is that they don’t come cheap! But by replacing an old boiler with a new one, you might be able to save hundreds of pounds every year in reduced energy costs.

Faulty Thermostat or Programme

When your boiler reaches the preset temperature, it should remain off. Your boiler might run continuously and use more gas as a result of a broken thermostat or programmer.

Make sure the temperature and timings are set correctly. Observe your boiler for any indications that it is operating even when you have switched off the thermostat or timer.

Faulty Valve

Motorized valves control the flow of hot water from the boiler. When the boiler is switched on, the valve opens to let hot water flow, and when it is turned off, it shuts to stop the flow.

There is a possibility that this valve may malfunction or become stuck. This will result in your radiators continuing to heat up when they don’t need to. The motorised valve would need to be replaced; check to see if the manufacturer’s warranty remains active.

How To Reduce Your Gas Usage

You can reduce your gas usage by using the boiler’s economy setting. This means it will turn on and heat your home at lower temperatures. You can also use the timer to put it on at certain times of day, so you don’t have to keep fiddling with the controls every time you want to increase or decrease the temperature.

Final Thoughts

Gas costs could be reduced if you maintain your boiler. Additionally, it can prevent issues that could result in lower energy efficiency and early failures. You should have your gas boilers tested at least once a year by an experienced gas expert.
