Frequently Asked Questions (FAQs)

1. 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.

2. Do double radiators give out more heat?

The longer the panel, the more surface area there is for the radiator to emit heat. Therefore, a radiator with a double panel of the same dimensions as a single panel radiator will give off more heat, as the total surface area is greater.

3. Does a double radiator give more heat than a single?

The main difference between single and double panel convectors then, is that the double panel will provide more heat than the single, and a double panel with a double convector (two sets of fins) will heat a space even quicker.

4. Is it better to have bigger radiators?

Larger radiators are more efficient as they can run at a lower temperature and still heat the room sufficiently. Some older radiators may not be able to handle the output from your new boiler, especially if you are getting a combi or a larger boiler than you had previously.
