Enjoy a little bit of the high life. For rooms with a narrow hearth, the Avalon 5 Slimline is an ideal choice. It is also our Best Selling Avalon model. This room heater retains the efficiency and output of an ampler model, so you can still enjoy a generous warmth on those cold winter nights. Boasting advanced stove technology for maximised combustion, this is a wonderfully eco-friendly option.
