Is Oil Radiator Cheaper than Gas?

Is Oil Radiator Cheaper than Gas?

Oil-filled radiators are relatively affordable with better features and safety that don’t come with expensive gas heaters, but this all differs from the running cost of oil radiators and gas heaters, and central heating systems.

When we compare the upfront costs of oil radiators and gas heaters, we find that oil-filled radiators are the cheapest, with the smallest model costing approximately £35 and the lowest gas heater costing around £50, but the major difference is the type of fuel they utilise.

The most important aspect influencing the price of gas and oil heaters is the operational cost. Using portable gas cylinders such as LPG, Butane, or Propane to power a gas heater is more expensive than running a large oil-filled radiator on electricity. However, using natural gas for your gas heater will be less expensive than using oil radiators.

It is a fact that determining the cost of power and gas, depends on your area and the current market conditions, which you can compare to see which is the cheapest option for your home.

The Running Cost of Oil-Filled Radiator Heater

The cost to operate a 500W oil radiator for eight hours at the current 31.8pence per kWh rate is 127.2pence. When you utilise the eco mode with that low-power radiator, you can expect to pay less than 15p per hour, which is a substantial saving.

Calculation: (500W = 0.5 x 8, then, 4 x 31.8p = 127.2p or 1.27 pounds and 2 pence)

It is estimated that the cost of energy in the UK has increased from last year 17 pence per kilowatt-hour to the current stable rate of 31.8p per kWh; current energy tariff reports.

If you want to know how much it’ll cost to keep your home warm and cosy with a 1,500-watt oil-filled radiator? Look no further! We’ve done the research and compiled a comprehensive pricing comparison using current electricity rates.

So, don’t let high heating costs freeze you out this winter, find out the cost per hour to run your oil-filled radiator now!

The Running Cost of Natural Gas Heater

Natural gas connection costs around 6.4p per kilowatt-hour, according to March 2023 price cap statistics. This means that running a gas heater on natural gas is significantly cheaper than running a 500-watt oil-filled heater on electricity.

However, the average cost of establishing a gas central heating system is around £5,250, and this is considerably higher than if building an electric heating system, which is roughly £3,790.

For LGP type: Contrary to the price of natural gas, LPG costs approximately 23p per hour to run a portable gas heater. This means that the small oil-filled radiator is a more cost-effective option, with a usage cost of less than 15pence per hour.

What is the Most Affordable Way to Heat a Home?

Many factors can impact the cost of heating a house, including the size of the house, the type of heating system, and the local climate. As a result, it is difficult to say definitively what the cheapest way to heat a house is, as the most cost-effective option will vary depending on your situation.

However, some general tips for reducing the cost of heating a house include:

Insulating Your Home

Properly insulating your home can help to retain heat in the winter and keep your home warm. This is because insulation acts as a barrier to heat flow, preventing heat from escaping through the walls, floors, and ceiling of your home. By keeping heat inside, insulation can help to reduce the amount of energy needed to heat your home, which can save you money on your energy bills.

There are several types of insulation that can be used in a home, including:

Blanket insulation:

This type of insulation comes in rolls or batts and is made from materials such as mineral wool and glass wool or removable PTFE laminates, silicone-coated fibreglass composite. It is usually installed in attics, walls, and floors.

Loose-fill insulation:

This type of insulation is made from small particles of materials such as cellulose or fibreglass, and rock wool is blown into attics or walls using special equipment.

Spray foam insulation:

This type of insulation is sprayed onto surfaces as a liquid and expands to form a solid foam. It can be used in hard-to-reach areas, such as around pipes or in small gaps in walls.

The optimal benefit of insulating your home will reduce the amount of energy your heating system has to use to maintain a comfortable temperature. For this purpose, you can either do it yourself or hire a professional contractor to do the work for you.

Before beginning any insulation project, it is important to determine the type and amount of insulation that is needed for your home, as well as the best location for installing the insulation. This will help to ensure that your home is properly insulated and that you can maximize the energy-saving benefits.

Using a Programmable Thermostat

The main purpose of using a programmable thermostat for a home central heating system is to improve the energy efficiency of the system by only running it when it is needed. By setting specific times for the heating to turn on and off, the thermostat can ensure that the heating system is not unnecessarily running when the home is empty or when the desired temperature has already been reached.

This can help to save energy and reduce the overall cost of heating the home. Additionally, a programmable thermostat can provide a more comfortable living environment by ensuring that the temperature is consistent throughout the day. Can be set for different times of the day, so you can reduce the heat when you are not at home or when you are sleeping.

Using a Heat Pump System

A heat pump is a type of mechanical-based system that uses a small amount of energy to move heat from one location to another. This can be used for both heating and cooling, making it a versatile option for regulating the temperature in a building or home.

In heating mode, a heat pump extracts heat from the air or ground outside and transfers it indoors, while in cooling mode, it does the opposite and moves heat from inside the building to the outside. This process is much more efficient than generating heat or cooling through the use of a furnace or air conditioner, respectively.

Using Fireplace and Space Heaters

In addition to the expensive central heating systems, alternative heat sources such as space heaters and fireplaces can be used to supplement the heat in your home. There is a wide range of space heaters available that offer portability and space-saving options, whereas a fireplace or wood burner chimney is a more permanent solution.

If central heating or a fireplace is too costly to install or operate, space heaters may be a more cost-effective option in certain situations. These include types of space heaters that include oil-filled heaters, gas heaters, ceramic heaters, infrared heaters, halogen heaters, radiant bar fires, heat convectors, and fan heaters.

These sources can be more cost-effective in some situations, such as when you only need to heat a particular room or when you only need to use the heat occasionally.


The decision to install an oil or gas heater will depend on a variety of factors, including the cost of the fuel, electricity, the efficiency of the heater, and the cost of the heater itself. To choose the most cost-effective option, it is important to consider all of these factors and consider your individual needs and situation. To improve the energy efficiency of your home, consider insulating your home, using a programmable thermostat, installing an oil-filled radiator or gas heater, and even upgrading to a central heating system is a good idea when money is not a problem.
