What are the Advantages of Electric Radiators over Oil and Gas?
1. Green and Efficient
First and foremost, electric radiators are much more efficient than their gas counterparts. Over the years, gas systems have largely remained the same – but electric heating has been constantly evolved as an energy efficient alternative. In fact, they can be up to 30% more efficient, which means that you’ll save money on your energy bills in the long run.
2. Less Noise
Gas systems can be far noisier due to hot water rushing through the pipes. Sometimes, it sounds much like a kettle boiling. This water rushing can sometimes become an issue in the long term, due to a build-up of sludge or limescale. So you might need a power flushing service to remove the build-up.
3. Cheaper and Easy to Install
Another advantage of electric radiators is that they’re very easy to install. Gas-fired systems need to be vented and require a professional installation, which can be both time-consuming and expensive. Electric radiators, on the other hand, can simply be plugged into a standard electrical outlet.
4. Safe
Finally, electric radiators are much safer than gas-fired systems as they do not burn fuel to generate heat. There’s no risk of carbon monoxide poisoning or explosions, making them the perfect choice for homes with young children or pets.
5. Long-term Value for Money.
Even though gas is cheaper to run on the daily than electricity, electric heating is cheaper to install than gas, has no maintenance costs and lasts for up to 50% longer than the average gas boiler. It is also 100% efficient, meaning all the electricity you use and pay for converts into heat.

What Tips Should I Consider when Buying an Energy Efficient Electric Heater?
As we have established above, electric radiators are a great way to heat your home and can be very cost effective. There are a few things you need to consider when purchasing a low cost, energy-saving electric radiator:
RATING MODEL
Firstly, make sure you choose an Energy Rating A model – this will ensure that your electric radiator is highly efficient and will help to keep your energy bills down.
ROOM SIZE
Consider the size of the room or space that you need to heat. Electric radiators come in a variety of sizes, so it’s important to buy one that is appropriately sized for the space.
HEAT LEVEL
Next, think about the level of heat you need. Some electric radiators come with multiple settings, so you can choose the one that best suits your needs.
EXTRA FEATURES
Finally, take into account any special features that you might want or need. Some electric radiators come with timers, so you can set them to turn on and off at specific times. Others have built-in thermostats, so they can maintain a consistent temperature.
By keeping these factors in mind, you can be sure to purchase an electric radiator that is well-suited to your needs.
Do Oil-filled Heaters cost a lot to Operate?
According to Delonghi, oil filled radiators are more economical to run because they retain heat longer. Also power demand through the temperature control is called upon less frequently.
Electric heaters on the other hand, heat only the room you are in and not the entire house. Thereby providing extra heat only where required and helping to optimise energy consumption.
Which is Better & Safer? Oil-Free or Oil-Filled Radiators?
Oil free, or dry radiators tend to be safer than oil filled radiators. This is simply because they don’t contain any oil at all, thereby greatly reducing the risk of the oil leaking or the radiator rupturing.
Is 2kW Expensive to Run?
According to a report carried out by Express, while 2kW is beneficial in terms of allowing greater control over the temperature and position in your home, they’re not cheap to run.
In fact, even under the current energy price caps, a 2kW electric fan heater costs 56p per hour to use on full power.
