Do I need an electric heater?
In a word - yes! Portable electric heaters are useful even if you already have a central heating system . When you only need to heat one room at a time, you can shut off the main system and rely on your economical, portable heater.
How do portable electric heaters produce heat?
Electric heaters work on the principle of electrical resistance. Heat is created when a current passes through a heating element.
There are three main types of portable electric heater: natural convection, fan-forced convection and radiant.
Natural convection heaters
Natural convection heaters contain a heating element immersed in a special type of oil.
They take longer to heat a room than a fan-forced model, but do so very evenly -there are no cold patches. The oil retains heat for a long time, so your room will stay warm even when the thermostat switches the heater off.
Natural convection heaters are particularly energy-efficient, and very rarely overheat.
