Electric radiators are 100% energy efficient, but electricity is expensive
Electric radiators are highly energy-efficient, with some models converting all of the electricity they use into heat. This 100% efficiency at the point of use means that every joule of energy is converted into heat, reducing running costs. The accuracy of inbuilt digital thermostats in electric radiators also helps to maintain energy efficiency and manage heating bills.
However, electricity is expensive compared to gas, and running costs can quickly add up. The average cost of electricity in the US is 16.83 cents per kilowatt-hour, and an electric heater can use up to 4.5 kWh per hour, resulting in high energy bills. In the UK, the cost of electricity is even higher, at £0.33/kWh for domestic use, compared to £0.10/kWh for mains gas.
For this reason, electric radiators may be more suitable for heating individual rooms or as a supplementary heat source rather than as the primary heating system for an entire house. They can be a cost-effective option if you only need to heat one room, as they provide a quick burst of heat and are easy to install and maintain. However, using multiple electric heaters in every room of a house can be more expensive than central heating, especially if the house is poorly insulated.
To minimize the running costs of electric radiators, it is essential to control and program them accurately. Modern electric radiators with built-in thermostats allow for precise temperature control, helping to maintain energy efficiency. Additionally, pairing electric radiators with solar panels or batteries charged through renewable sources can significantly reduce energy costs.

Gas heating is cheaper, but electric heaters are more convenient
Gas heating is generally the cheaper option compared to electric heaters, but electric heaters have their advantages. Electric heaters are more convenient as they are portable, easy to install, and can heat up individual rooms quickly. They are also more stable as they are not affected by blackouts or geopolitical issues that can cause fluctuations in natural gas prices.
Electric heaters are a good option if you only need to heat one room, as heating your entire home with electric heaters can be costly. The US Department of Energy recommends setting your thermostat to 68°F during the daytime and a few degrees lower at night or when you're away to save on energy costs.
The cost of electricity versus natural gas heating can vary depending on factors such as the cost of energy sources in your area, the efficiency of your heating system, and the amount of energy used. On average, homeowners pay 63% less when using gas heat than electric heat. However, a newer, more efficient electric heating system may be more cost-effective than an older natural gas system.
Electric radiators have built-in thermostats, allowing you to control the temperature accurately and programme them to maintain energy efficiency. They are also 100% energy efficient at the point of use, with every joule of energy converted to heat.
While gas heating is typically cheaper, it is less efficient than electric heaters, with gas furnaces having an energy efficiency of 70-90%. Gas heating also releases particles, allergens, and irritants into the air, affecting the air quality in your home.
Ultimately, the decision between gas and electric heating depends on your specific needs, the size of your home, and the energy costs in your area.

Electric heaters are cheaper for heating single rooms
Electric heaters are a convenient way to heat a single room, especially if you are the only one in the house. They are portable, easy to install, and low maintenance. However, the cost of running electric heaters can be high, depending on factors such as size, type, and location.
When deciding between electric heaters and central heating for a single room, consider the following:
Electric heaters are generally more expensive than central heating when used to heat an entire house. However, for a single room, they can be more cost-effective. This is because you only pay to heat the room you are occupying, rather than the entire house. Additionally, some central heating systems do not allow you to turn off radiators in individual rooms, making electric heaters a more economical choice in such cases.
The type of electric heater you choose also impacts cost-effectiveness. Infrared heaters, for example, use less energy than traditional electric heaters, giving you more control over the temperature in each room. Oil-filled radiators are another option, as they heat up slowly and cool down gradually, reducing the need to constantly turn them on and off.
To calculate the cost of running an electric heater, you can use the formula kilowatts multiplied by the rate you pay for electricity multiplied by the usage time. This will help you make an informed decision about the most cost-effective heating option for your needs.
It is worth noting that there are alternative ways to stay warm without relying heavily on central heating or electric heaters. Using blankets, hot water bottles, or heated jackets can help direct heat towards your body, reducing the overall energy consumption required to stay comfortable during colder months.

Solar panels can reduce the cost of running electric radiators
Electric radiators are standalone units that are installed on internal walls around the home. They are simple to install and easy to replace. They are also 100% energy efficient at the point of use, as every joule of energy you pay for is converted to heat.
However, electricity is incredibly expensive compared to gas. Therefore, electric radiators can be costly to run, especially if you are using them in every room.
Solar panels can power electric radiators, along with any other electric appliance, providing your home with self-sustaining, carbon-neutral energy. The energy generated from solar photovoltaics (PV) can be paired with any electrical appliance and works equally well with electric radiators. The solar inverter converts the DC electricity and generates it into AC, which is then fed back into the mains of your home. This green energy can then be used to run your electric radiator at little to no cost.
For example, Karen and Mike from Cambridgeshire opted for a new electric heating system from Intelliheat and Solar PV installation. The 12kW PV system can generate up to 50kWh on sunny days, with a minimum of 15kWh generated on cloudy days. This is more than enough to power their electric radiators for around 6 hours a day.
Therefore, solar panels can reduce the cost of running electric radiators by providing a source of renewable energy to power your home.
