About the Startup Describe your products in 3 words.Simple, Ingenious, EffectiveHow did you come up with the idea for this product?A few years ago I was sat on the sofa next to my wife and she would always complain about being too cold, even though the central heating was on and the radiators were warm. It was clear that all the heat from the radiator was going straight up, escaping out of the window or getting trapped at the ceiling. I decided to see if I could redirect that heat flow out into the room and that's where the idea for the Radfan was born. The initial prototype was a great success, not only did we feel warmer, my wife stopped complaining!What makes your product special?The Radfan is the only product on the market that is guaranteed to make your home warmer, without having to spend more on your energy bills.What has been the best part of your experience?The best part of the startup experience for us has been the freedom to create and come up with new ideas.

The ones that clip on the top or the bottom of the radiator?** A: Hi, not sure about the ones that clip on top as our radiator is in a cabinet and the one that goes on top wouldn't have fitted. I can say that i originally got the slim small and didn't notice much of a difference so sent it back and got the medium with the 4 fans which made a noticeable difference and the room heats up quicker now. **Q: i tried attaching it to the radiator, but its not magnetic so wont attach? what am i missing?** A: The fan is a sort of L Shape with a lip that comes up the front of the radiator. The magnets are in that lip and that should sit on the front of the radiator. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/50108284-slim-small-low-power-radiator-fan](https://www.desertcart.us/products/50108284-slim-small-low-power-radiator-fan) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-23*
