If you’re trying to decide which sort of patio heater to buy, you may have dismissed electrically powered ones as the most expensive to run.  Traditionally, electric appliances have been more expensive than gas.  But the way that infrared outdoor heaters work, makes them surprisingly economical. 

How do they work?

Infrared energy travels through the air and only heats the objects which the heater is directed at.  It doesn’t waste energy by heating the air in between itself and whatever it’s heating.  Convection heaters which do heat the air are at the mercy of the wind.  The smallest breeze can mean a large loss of heat.  As radiant infrared doesn’t suffer this loss, it makes it a very energy efficient heating method.  The other good news is that some models have 3,000 hours of bulb life!

Infrared heating doesn’t produce any condensation, fumes or hissing noise – as it is a ‘dry heat’ system.  Another bonus is that because this method of heating doesn’t move any air or dust it makes it a clean and environmentally friendly choice.

Which model to choose?

You’re not stuck with purely electrical infrared heaters.  These days, they can be run by natural or propane gas which means that you can position them anywhere as you’re no longer restricted by the length of an electrical cord. 

There are many models available.  You can choose from freestanding, table top or wall fixed. 

A word of caution.  

If you want a permanent wall fixed infrared heater, check that the model you choose is safe to stay outside in all weathers.  Not all are, so take care.  Check if the element is exposed or protected.  If it is exposed, once it is switched on it will become very, very hot and even a few drops of water on it could cause a very loud bang!

You will see some electric infrared outdoor heaters that have exposed elements being sold as safe if used underneath awnings and garden umbrellas.  But just remember that rain doesn’t always fall down from the sky in a straight line.  Light drizzle can be blown in all directions and a metal grille won’t prevent drops of water from landing on the electrical element. Some are sold as ‘splash proof’ but this would not be enough to keep it safely outside in the rain. 

Look for models which are sold as ‘completely weatherproof’ and enjoy the warmth of the sun on your patio all year round!
