Low Surface Temperature Radiators are an excellent choice for the whole families, due to the fact their surface temperature never reaches more than 43 degrees, preventing any accidental scalding. Single panel convector radiators, otherwise known as Type 11 radiators, are brilliant for heating smaller rooms. They aren’t to be confused with a normal single panel radiator without the convector as they provide much more heat output in comparison. They are thicker than a normal single panel radiator but that is totally worth the increase in heat output. They're ideal for hallways as just one convector and one panel ensures a slim projection.
