Product Information

Maximise heat from your radiators and you could save £££s on your bills.

Maximise heat and help to save energy with Bergstrom's HeatBoost Pro. Placed on top of your radiator, it prevents heat from escaping up walls, out of windows and into ceilings. Instead, quiet turbo fans capture the heat and throw it directly back into the room, heating your space fast and efficiently, reducing the need to have your heating on higher.

Choose manual or auto mode
Auto mode automatically activates when the direct heat of the radiator is 33°C and above, when your heating is set to between 18 and 20°C (depending on the type of radiator), then auto shuts when your heating is off. Manual mode allows you to switch on/off whenever you want.

Lightweight, portable and rechargeable
Designed to fit almost any radiator in your home or office and powered by a rechargeable battery (USB lead supplied), it offers easy and convenient portability for cosy comfort anywhere. H11.5 xW31.5 xD11.5cm.

The HeatBoost Pro has a universal design which suits both single and double radiators only. Do not use with oil, electric or open flame heaters. Please refer to our fitting guide.

"Great Purchase"
Love them. The heat nows blows back into the room. My husband refers to them as the nissan huts. You know the design. So when I get asked to put the nissan huts on I know it is cold.
