How Dangerous Are Electric Heaters?

When it comes to heaters, electric heaters are generally the least dangerous but can still cause some serious damage or harm if not used in the correct manner.

Electric heaters should never be left unattended, especially when being used around children or pets. The heater can become extremely hot and if touched can cause extreme burns.

Most electric heaters have a tip-over cut-off, this is a safety feature wherein which the heater has a sensor that detects whether the heater is stood upright or has been laid flat if the heater has been laid down or knocked over the heater will not power on.

This feature should never be taken for granted and your heater should always remain in its intended upright position.

When using your heater outdoors remember to never use it if there is any chance of rain or mist in the air, moisture can be very damaging to an electric heater and can be an electrocution hazard.

When plugging in your heater, make sure never to use an extension cable that doesn’t have a trip-switch fitted, and always make sure the flex is covered to stop any trips or falls.

You should consult your heaters handbook for the appropriate safety tips for using your electric heater and to gauge how much electricity they will use.

How Should I Store an Electric Heater?

During summer months you might decide that you don’t require your electric heater so storing it might be a good idea.

Electric heaters should be stored in a dry area, preferably within the box that the heater originally came in.

Check your heater for lugs underneath or to the rear, these are used to flex around to enable safe and efficient storage.

When storing your heater now would be a good time to check for any damages, if you have any frayed wiring you should take your heater to a trained electrician who can replace the wire and repair any other damage that you may have.

Never try to repair your heater yourself, if you have any concerns you should seek out professional help or ring the helpline that was provided in your manufacturer’s booklet.

Never use a faulty heater, and never cover one up whilst it is in use. A heater should be put in an area that is free from any obstacles and away from anything that is flammable.
