Coopers Of Stortford HeatBoost Pro Radiator Fan Heater (White)

How does the auto mode work and when does it activate?

Auto mode uses a built-in thermostat that monitors your radiator temperature. The fans automatically start when the radiator reaches 33°C and stop when the heating switches off and temperature drops. This ensures the unit only operates when there's actual heat to circulate, saving battery life and preventing unnecessary noise when radiators are cold.

Will this work with both single and double radiators?

Yes, the HeatBoost Pro fits both single and double radiators. The 31.5cm width accommodates standard UK radiator sizes. The lightweight design sits securely on radiator tops without additional mounting hardware. The compact 11.5cm depth means it won't protrude excessively from your radiator.

How long does the battery last and how do you charge it?

Battery life depends on usage patterns and fan speed settings. The unit includes a USB charging lead for convenient recharging from any USB port or wall adapter. A battery level indicator shows remaining charge. In auto mode, battery consumption is reduced as fans only operate when radiators are actively heating.

How much noise do the fans make during operation?

Customer feedback indicates the fans are audible during operation, with some users finding them too noisy for bedroom use overnight. The manufacturer describes them as "quiet turbo fans" but reviews suggest they produce noticeable fan noise, particularly in quiet environments. Consider placement away from sleeping areas if noise sensitivity is a concern.

Does this actually save money on heating bills?

The unit improves heat distribution efficiency by preventing warm air from rising and escaping through walls and ceilings. By circulating radiator heat more effectively throughout rooms, you may achieve comfortable temperatures without increasing central heating settings. However, the actual savings depend on your home's insulation, radiator efficiency and heating usage patterns.

What are the exact dimensions and will it fit my radiator?

The HeatBoost Pro measures 31.5cm wide, 11.5cm deep and 11.5cm high. It's designed to sit on top of standard UK radiators without overhang issues. The lightweight plastic construction won't damage radiator surfaces. Check your radiator's top width to ensure the 31.5cm width will fit properly.

Can you use this in manual mode all the time?

Yes, manual mode allows continuous operation regardless of radiator temperature. This gives you complete control over when the fans run. However, continuous operation will drain the battery faster than auto mode. Manual mode is useful when you want consistent air circulation or when the auto mode's 33°C activation temperature doesn't suit your needs.

Are magnetic feet included for radiator attachment?

The product description mentions magnetic feet, but customer reviews indicate some units may not include them. The device is designed to sit securely on radiator tops through its own weight and design. If magnetic attachment is important to you, contact the seller to confirm inclusion before purchase, as there appears to be inconsistency in what's supplied.
