In short, electric radiators are very safe. They’re extensively tested against a number of strict regulations, guaranteeing their safety in a variety of locations. Let’s run down some features that make them rank so highly in the safety department…

Electric radiator safety features

  • Intuitive technology - with 24/7 programming and WiFi app control a prominent feature, leaving your electric radiator on by accident is a thing of the past.
  • Robust warranties - a marker of quality, any electric radiator with a significant warranty is testament to its high level of safety.
  • IP ratings - advising you on where you can and cannot place them around the house, IP ratings are essential when installing in a bathroom. For example, the Ecostrad Ecowärme is IP20 rated meaning it is not protected from the ingress of water and therefore not suitable for bathroom installation. However, other electric radiators such as the Ecostrad Ascoli, come with an IPX5 rating, which means it can be fitted in zone 3 of any bathroom. Take a look at our blog on this topic for more information.
  • CE markings - All our electric radiators are CE marked, meaning they conform to all the EU safety tests that make them suitable for sale.
  • Overheat protection - any electric radiator with overheat protection will cut power well before your radiator is able to reach an unsafe level.

When is it safe to leave electric radiators on all night?

Whether it’s for safety or energy-efficiency, we are constantly being told not to leave electric devices on overnight and you may think electric radiators are the same. When used correctly, electric radiators are completely safe and have been designed as direct replacements for central heating. So, as long as your electric radiators are fixed to the wall with no obstructions, you can in fact leave them on overnight. Just make sure that they are not covered by any curtains or clothing as this can lead to overheating.

One of the best features of our electric radiators is their precision thermostats that stop them drawing power once they have reached their desired temperature, so technically, they will still provide that necessary warmth without actually being on all night. This means that you can go to bed and wake up with the same comfort level every day of the week, with the knowledge that you are totally safe to do so.

When is it not safe?

Although fixed radiators can be used overnight, free-standing electric radiators can pose a risk if left unattended, as they can be knocked over. As such, it is not recommended to leave them running throughout the night. Imagine leaving your radiator on all night to keep your pet warm and they accidentally push the appliance over - it's best to avoid such risks altogether by not leaving your free-standing electric radiators on overnight.

The energy saving option

For those who are environmentally conscious, you may not want your electric radiators to provide heat all night, but still want to be warm and comfortable first thing in the morning. Well, you’re in luck as our electric radiators come with a range of energy saving features that also help to ensure you get the right amount of heat at the right time of day.

Energy-saving features

  • 24/7 programming: set a heating schedule that matches your lifestyle and individual routine, so your heating only ever comes on when you need it. This is perfect if you want your heating to switch on or off at certain times throughout the night.
  • Adaptive start: this handy feature begins warming your spaces in advance to maintain your desired temperature at the start of their schedule. This means your room is warm for the time you’re hopping out of bed - not switching on from cold at that time.
  • WiFi controlled electric radiators: allowing you to control your heating from the comfort of your chair or bed, these clever units make adjusting your radiators’ settings through your smartphone or tablet a dream.

Installation of electric radiators

If your needs suit overnight heating, it is worth considering wall-mounted installation. You can wall-mount electric radiators yourself with straightforward DIY installation, so you don’t have to pay a professional, saving on costs. Our flagship product, the Ecostrad iQ Ceramic comes with its own fittings, template, cable and plug to make installation as easy as possible. With WiFi control, 24/7 programming and adaptive start in tow, the iQ Ceramic is designed to be a direct switch for a central heated radiator, and as such, can be left on overnight with zero worries.

Electric radiators and overnight running

Don’t lose sleep over it - if your electric radiator is wall-mounted and unobstructed, it can be left on overnight. Modern units, with their myriad of safety features, make waking up in a warm room possible, and with energy-saving features like adaptive start and 24/7 programming, your carbon footprint doesn’t need to take a hit. Just remember, portable electric radiators should never be used for overnight heating, and you should always switch your unit off when it’s not in use.


Key Takeaways

If your electric radiator is securely fixed to a wall and unobstructed (no curtains or clothes dangling over them) they are fine to be left on overnight.

If your electric radiator is freestanding or portable, it should never be left on overnight.

Electric radiators with energy-saving functions like 24/7 programming and WiFi control are a eco-conscious way of making sure you wake up to a warm room.
