  • Gas Fires vs Central Heating: Which is More Cost-Effective?

Updated: October 26, 2024

As energy prices continue to rise, many households are searching for ways to reduce heating expenses. In this article, we’ll explore whether gas fires or central heating provide the most cost-effective solution for keeping your home warm.

Central Heating vs Gas Fires for a Single Room

When comparing central heating to gas fires, many people assume that gas fires are cheaper for heating a single room. However, modern central heating systems tend to be more efficient in heating an individual space, especially if equipped with thermostatic radiator valves that allow you to control the heat in each room individually.

By focusing heat on one room, central heating can often outperform a gas fire in both efficiency and cost, making it the better option for many households.

Cost of Running Central Heating

The cost of running central heating can vary significantly depending on several factors, such as:

  • Boiler efficiency
  • Size of the home
  • Insulation quality
  • Thermostatic radiator valves

Gas central heating remains one of the more affordable options, averaging around £0.10 per kWh. However, if you use electricity or other fuel sources, the costs will be different:

  • LPG: £0.12 per kWh
  • Electricity: £0.34 per kWh (for electric boilers and heat pumps)
  • Oil: £0.09 per kWh

Gas Fire Running Costs

Gas fires typically range between 3kW and 7kW in power output. Given that the current average cost for gas is about £0.10 per kWh, this translates to running costs of around £0.30 to £0.70 per hour, depending on the fire’s power output. You can calculate the specific running cost using the formula:

Gas Fire kW output × cost per kWh = Hourly Running Cost

For instance, if your gas fire has a 7kW output, it would cost approximately £0.70 per hour to operate.

Is Central Heating Cheaper Than Gas Fires?

Generally, central heating is more cost-effective for heating a single room. This advantage comes from its ability to focus heat more efficiently, especially with adjustable thermostatic valves that limit heating to the spaces where it’s needed.

However, an electric boiler can be a different story due to its higher running costs at £0.34 per kWh. In such cases, pairing an electric heating system with renewable energy sources like solar panels could drastically reduce costs.

Factors That Influence Heating Costs

There’s no simple answer to whether central heating or gas fires are cheaper, as the most cost-effective option will depend on several factors, including:

  1. Size of your home: Smaller homes may benefit more from gas fires in localized areas, while larger homes are better served by central heating.
  2. Thermostatic control: If you have smart thermostats or radiator valves, central heating could provide more precise control, reducing overall costs.
  3. Type of heating system: Electric-based systems tend to be more expensive, while gas is typically more affordable.

Tips to Lower Heating Bills

Whether you’re using central heating or a gas fire, there are several ways to reduce your energy usage and lower your bills:

1. Limit Your Energy Use

The simplest way to cut down on heating costs is to use less energy. By being mindful of when and how often you run your heating, you can significantly reduce your energy consumption.

2. Avoid Leaving Heating On Constantly

Many people mistakenly believe that leaving heating on at a low level constantly is more economical. This is false. It’s more cost-effective to turn the heating on only when needed. Installing draft excluders and ensuring good insulation will also help keep the heat in and reduce the need for constant heating.

3. Turn Down the Thermostat

Reducing your thermostat by even one degree can have a dramatic impact on your energy bill. In fact, it could save you up to £80 a year. Additionally, lowering your boiler’s flow temperature can result in a further 8% reduction in heating costs.

Heating a Single Room

Heating a single room with central heating can be done efficiently, especially with modern systems that allow for zoning. Depending on your heating system’s efficiency, the cost of heating a room for an hour may be as low as a few pence to around £0.70. The key is to optimize your heating system to focus only on the rooms that need it.

Heating Your Whole House

Gas fires are not suitable for heating an entire home, but you might consider combining a gas fire with other localized heating methods, like electric heaters, for different rooms. However, this approach may not necessarily be cheaper than running your central heating, especially if you still need to heat a significant portion of your home.

For small homes, central heating is likely to be the most cost-efficient option. Using a gas fire and additional heaters could potentially cost more, particularly if the heaters are inefficient or run on electricity.

The Risks of Insufficient Heating

One crucial consideration is ensuring that everyone in the home remains adequately warm. Insufficient heating can lead to health risks, especially for vulnerable individuals like the elderly or young children. Always prioritize maintaining a safe and comfortable environment, and consult a professional if you’re unsure about your heating setup.

FAQs

What is the main difference between gas fires and central heating?

Gas fires heat individual rooms directly using gas, while central heating warms the entire home through a network of pipes and radiators.

How does each system impact gas or electricity bills?

Gas fires can be more economical in certain situations, while central heating might lead to higher energy consumption due to its size.

Can both systems be used together?

Yes, gas fires can be integrated with a central heating system to provide additional warmth in areas that require more heat.
