Our electric radiators are filled with a heating solution called Glycol. This is a thermodynamic fluid that heats up and expands when the appliance is switched on. As the fluid expands, it gives off heat which is then transferred to the surface of the radiator columns, which in turn heat your space to a nice warm temperature. Note that Dry Heat or Dry Thermal radiators do not contain any heating solution, hence the name “dry”. These radiators feature a heating element that snakes around the columns of your appliance to heat the columns in a slightly different way.
