Are there energy efficient electric radiators? - Reduce that footprint (2023)

For cost reasons, electric heating is a more expensive way to heat

From a purely economic perspective, electric radiators are one of the worst ways to heat the house. Our website had made oneCost Comparison of Different Ways to Heat a Home. Electric heating is more expensive than oil and natural gas. And by electric radiators we don't mean heat pumps, just pure electric radiant heaters.

The situation is different when it comes to CO2 emissions. Whether or not electric heating is good for CO2 emissions depends on where you live. This is because where you live determines the source and carbon intensity of electricity.

When it comes to emissions, when it comes to electric heat, it depends on where you live.

Living in a Scandinavian country means your electricity is more likely to come from nuclear, hydroelectric and geothermal sources, all of which are low carbon. Living in South Africa means your electricity is more likely to be oil-based and carbon-intensive. So using an electric radiator in the first country is less polluting than using an electric radiator in the second. For a quantitative comparison, we have also covered those on this locations for low carbon energy sources.

so in shortnext toheat pumps, the answer isNO, Electric radiators are not energy efficient. However, they are carbon efficient if you live in the right place! To validate and make your decision, you need to know the average CO2 emissions of your network in grams of CO2 per kWh of energy generated. If the CO2 emissions from your electricity are lower than an alternative like natural gas, then it's okay to switch.

In the US, switching to electric heat would result in a higher bill than natural gas or using a heat pump. Their prices depend on where you live. Scenario 1 – If you end up paying less for cleaner electricity, that's a no-brainer and you need to change. Scenario 2: If you pay more for clean electricity, you pay the "first green“. The green premium threshold is a personal preference. 3, if you pay less for dirtier electricity, express your preference not to pay the green premium. 4, the last scenario is to pay more for dirtier electricity, no one would do that, right?

What are electric radiators?

Electric radiators are aSpace heating typeIt uses electricity to generate heat. Unlike traditional space heaters that use gas or oil, electric radiators are 100% efficient, meaning that all the energy used is converted to heat.

Electric radiators are becoming increasingly popular for heating homes and businesses, but what makes them so energy efficient? Simply put, electric radiators are designed to maximize the use of electrical energy, minimize heat loss, and maximize comfort. For example, many models featurethermostatic controlsthat allow the user to program the optimum temperature for their space. When the set temperature is reached, the heater will automatically shut off, avoiding energy waste.

Besides,advanced thermal imaging technologyit is often used in the construction of electric radiators. This ensures that the heat generated by the radiator is distributed evenly, further reducing energy waste. As such, electric radiators can offer an extremely efficient and cost-effective way to heat any space.

Here are 7 types of electric radiators

Electric radiators come in a variety of sizes and styles, making them a versatile heating solution for any space. Here are seven of the most effective and efficient electric heaters:

1. Radiant heater

Radiant heaters work by emitting infrared radiation, which is then absorbed by objects in the room, causing them to heat up. Heheating typeit is very efficient since it does not depend on convection to distribute heat throughout the room.

2. Heating panel

They work by heating a metal plate, which then radiates the heat into the room. This type of heating is also very efficient because air does not have to circulate to distribute the heat.

3. Oil filled radiators

Oil radiators are filled with a special oil that retains heat for a long time. Once the radiator has been turned off, the oil will continue to radiate heat into the room, providing a consistent and constant source of heat.

4. Infrared heater

Infrared heaters work similar to radiant heaters, but use infrared waves instead of radiation to heat objects in the room. These waves are invisible to the naked eye, but are very effective in heating the objects they come into contact with.

5. Storage heaters

Storage heaters are designed to store energy overnight when electricity prices are lower and then release that stored energy during the day when prices are higher. This makes them an extremely economical way to heat your home, as you can take advantage of cheaper off-peak electricity rates.

6. Fan Assisted Storage Heaters

As the name suggests, fan-assisted storage heaters have a built-in fan that helps circulate stored heat around the room, making it even more efficient at distributing heat throughout your home.

7. Underfloor heating

Underfloor heating is an extremely efficient way to heat your home, as it circulates warm air around the room without relying on convection currents. This means very little energy is wasted as all the heat is distributed evenly throughout the room. Underfloor heating is also very gentle on your feet, as there is no risk of burns on hot surfaces.

Advantages of electric radiators

Electric heaters are a great optionHeat your home in an energy efficient way. These are some of the advantages of electric radiators:

1. Electric radiators do not require venting, unlike gas or oil heaters which require venting to the outside. This means that you can place electric radiators anywhere in your home without worrying about ventilation problems. Venting complicates installation by requiring piping outside of the house. Ventilation pipes are subject to regulations and technical requirements.

2. Electric heaters are safer than other heating methods as there is no risk of carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that is a byproduct of burning fossil fuels and is dangerous if inhaled.

3. Electric radiators are a low maintenance option as they do not require yearly maintenance like oil heaters. Natural gas heaters are also typically fairly low maintenance. All you have to do is keep the cooler clean and dust free and it will last for many years.

Disadvantages of low consumption electric radiators

As people look for ways to reduce their energy consumption and costs, energy efficient electric radiators are becoming more and more popular. However, before you make the switch, there are a few issues to be aware of with these radiators.

1. They cost more to run than non-electric radiators or heat pumps.

2. They occasionally generate an annoying hum. This is usually due to incorrect installation or loose connections, but it can still be a nuisance.

3. Radiant heat may take longer to heat up than traditional radiators. This can be a problem on cold mornings when trying to get warm in a hurry.

4. They generate quite a bit of heat on their own, which can make them uncomfortable to touch. This is not usually a problem when the radiator is installed high against a wall, but it can be a problem when the radiator is installed at ground level. But radiant heaters that feel warm can also run on natural gas and other heating devices.


Electric radiators are an option to heat a house. They have a number of advantages over conventional natural gas or oil combustion. These advantages are being displaced by better natural gas products and heat pump technologies.
