Hi can I install an electric towel rail upside down? I'm replacing a fan heater where the electric outlet is high up.

The standard Revive towel warmers we sell have a 1/2" female thread on all 4 connections. The element will fit any of the 4 connections, but installing the element at the top may cause the towel warmer to take longer to warm up this is because heat rises, which is why elements are usually fitted at the bottom. Also we would recommend checking with an electrician regarding fitting a towel warmer element to an electric outlet that was previously used for a fan heater as this may be too powerful.
