Frequently Asked Questions (FAQs)

1. Are triple panel radiators worth it?

For the greatest heat output consider a triple radiator which uses a combination of three panels and three convectors. Great for larger spaces, they're also ideal if you are extending a room and don't want to install additional radiators.

2. Can you get a triple radiator?

This triple panel triple convector radiator is the perfect combination of efficient heating, reliability and value. This is an easy-fit, high-efficiency radiator with a wide choice of sizes and shapes to suit any room at home or in the workplace.

3. Is it better to have double radiators?

Doubles are great for heating large and medium-sized rooms because the 2 convector fins will increase the surface area and heat the room quicker. Both types are panel convector radiator units. However, the use of the double panel allows the heat output to generate faster.

4. Do different radiators give more heat?

The longer the panel, the larger the heat emitting surface area, so bigger radiators will emit more heat, but also remember that a double panel radiator will emit more heat than a single panel radiator of the same length.
