Radfan Radiator Fan - Classic Long 5 "Excellent product" Mrs Carson 02 December 2018 Purchased the Radfan radiator fan to see if it would improve the heat from the radiator in my living room, and I have not been disappointed. Cannot believe the difference this has made, and so simple to install. There is a slight noise when the fan is in operation, but I actually find this quite comforting and not at all intrusive. So pleased with this product, I have purchased a smaller one for my kitchen. Would definitely recommend. I must add, excellent customer service from Lakeland.
