Using the most energy efficient radiators this winter is a top priority with the cost of energy bills these past couple of years. Now is the time to evaluate the options to warm up our homes. Energy efficiency is the first and most important factor to be considered. There are many types of heating and many sources of heat, but which one to choose?

Important hack: the size

It might not sound important, but your radiator sizing is essential to be considered. You cannot just judge a radiator by the physical size of the product itself with a quick guess. A lot more technical work should go into your sizing when trying to workout the most energy efficient radiator for your space. This is why we offer our free survey. Each house has its own unique needs, and each room in that house has different uses and size requirements. Choosing a radiator able to match the room’s needs could help you save a lot on energy bills.

A bigger radiator has a larger surface area heating the room. This means, that for a smaller radiator in the same room, this one would have to use more energy to warm up the room to the same temperature. On the other side, it is also crucial to consider that when the radiator is too big for the room it is in, it will most likely overheat it, ending in a waste of energy and money.

Choosing the correct size radiator should be based on a heat loss calculation carried out through:

  • Inspection of the building materials
  • Room area
  • External walls
  • Window / door sizings
  • Insulation
  • Room use
Most Energy Efficient Radiators in 2021

Solid Core Electric Radiators

As we might already well know, electric radiators have the advantage to be 100% energy efficient. This means that 100% of the energy used will be turned into heat output, there is no wasted energy. Solid core German Electric radiators allow heat retention thanks to the solid stone cores inside. For every 12/15 minutes of energy consumed, our Dynamic Evoke electric radiators will provide you with 45 minutes of retained heat and continued heat output.

In a traditional central heating system, water is pumped into the radiators, all over your house. The radiator is then heated by the energy warming up the water and passing to your room. In this scenario, wet system boilers are usually between 70 – 90% efficient due to energy loss. Not only that, this type of system provides very little control of your individual room heating requirements and is most likely controlled via one central thermostat.

Electric radiators are simple to use and have low to no maintenance requirements. Plus, they allow you to control them when you are away from home as they are wifi controlled and keep control the temperature of each individual room with a built in thermostat.

Indeed, the energy price for electricity is higher than the gas, but used correctly and paired with renewable technology such as solar and battery storage, electric radiators can be the most energy efficient radiators available.

Pros Cons
  • Location flexibility
  • 100% efficiency
  • Eco-friendly
  • Heat retention
  • Temperature control
  • Smart features
  • Low-maintenance
  • Cost of electricity compared to gas


Dual Fuel Radiators

Dual fuel radiators are powered by both electricity and gas. You can choose if you’d like to warm up the radiator powered by your central eating or by electricity. There is also the possibility to isolate one of the radiators and heat only one room using electricity. This solution might be a little more of an investment as compatible radiators need to be purchased, along with a heating element and further controls.

Pros Cons
  • Allows heating single rooms
  • Uses less gas
  • The switch is quick and easy
  • Use your current radiators
  • There is still a partial loss in energy due to the central heating
  • It is less eco-friendly
  • Each radiator needs to be manually operated.


Aluminium Radiators

If you would like to remain with your central heating system, switching to aluminium radiators might be the way to go. Aluminium is a great heat conductor, allowing it to heat quickly and use less energy.
Not only that, they are easier to recycle, but they also use less water, again, requiring less effort from your boiler, which is great for the environment and allowing some savings! They are advised for occasional use as normal iron radiators warm up rooms more evenly. They can also be a cheap alternative to giving your current heating systems a energy efficient boost without breaking the bank.

Pros Cons
  • Great Heat conductor
  • Cost efficient
  • Quick heater
  • Eco-friendly
  • High maintenance – as per central heating
  • Un-even heat
  • Cooldown as quickly as it heats up
  • When it warms up it is really hot and could be dangerous


Double Panel Radiators

These radiators work by increasing convection heat and are also called “Type 22”. This is because they are composed of 2 steel panels and 2 convectors one on top of the other, both emitting warm air in the room. They are a great suit for bigger rooms that needs to be heated quickly. However, they might be the least energy efficient of the 4.

Pros Cons
  • Heat up quickly
  • Save space in the room
  • Higher heat output
  • They look bulky
  • Too powerful for smaller rooms
  • Bland and basic designs.


All of these solutions are good to be taken into consideration for your house. And it depends on what you are looking for and what priorities you have for your heating.
