How Radiator Booster Works?

Heat Diverter for Radiators – Smarter Warmth, Lower Gas/Energy Bills

What Makes a Radiator Diverter Different?
Conventional radiators send most of their warmth straight up to the ceiling through natural convection. A heat diverter sits neatly on top of your radiator, capturing that rising heat and redirecting it outward into your living space.

  • Banish Cold Spots: Stops warm air from gathering uselessly near the ceiling.

  • Better Air Movement: Guides heat across floor level, right where you need it.

  • Quicker Warm-Up: Rooms hit your desired temperature noticeably faster.

  • Zero Running Costs: Works entirely without power - no electricity, no batteries.

The Problem With Standard Radiators
Without a diverter, your heating system battles "thermal stratification" - the tendency for hot air to hang around at ceiling height while you stay cold below.

Rooms can feel draughty even with heating on Steady, even temperature throughout


Choosing the Right Size
Getting the perfect match is essential. Always go by your radiator's top grill width. Our diverters come in a broad size range:

  • Available Widths: 400mm to 2000mm (the unit itself is 50mm shorter to allow for solid radiator side panels).

  • Smart Two-Piece Design: Models 1200mm and above split into two sections for safer shipping and simpler handling.

Handy Hint: Measure the full width of your radiator's top grill before placing an order, it's the best way to guarantee a snug fit.

Will It Fit My Radiator?
Our diverters work with the majority of standard home radiators, including:

  • Single panel (one layer of convection fins)

  • Double panel (two layers of convection fins)

Please Note: These diverters are not designed for electric radiators, curved or horizontal grills, or radiators without a top grill opening.

Clip-On Installation in Half a Minute

  • No Tools Needed: Forget drills, brackets, or calling a plumber.

  • Effortless Setup: Just rest the diverter along the radiator's top grill.

  • Versatile: Works equally well on older heating systems and modern efficient models.

Why You'll Notice the Difference

  • Trim Your Bills: Get more value from the heat you've already generated.

  • Guard Your Décor: Curtains and walls stay cleaner and cooler.

  • Immediate Effect: Feel improved circulation the moment your radiator warms up.

  • Fit and Forget: Tough materials, no upkeep required.

Final Thoughts: Does It Deliver?
Yes, a radiator heat diverter offers exceptional bang for your buck. It's a simple, one-time change that helps your current heating perform better, keeps you cosier, and cuts wasted energy with zero effort on your part.
