This wall mounted heater by Optimus would make an absolutely great heater for a shed.

Its design only really allows it to heat small areas, so it wouldn’t be suitable for anything much larger than a shed such as a garage but that fact that it is wall mounted and powered by electricity means it will always be there when you need it.

You can control its output with a dial giving you great control over the temperature your shed reaches as well as the fuel consumption unlike other heaters which just switch between two or three modes.

This heater uses propane as a fuel so you will need to purchase propane canister separately but it does come with a standard 10ft hose which is great value. It’s also very easy to assemble and allows you to easily adjust the angle that the blower points towards.

Their Uberheat ceramic heater isn’t just smart and stylish but it is a brilliant personal heater that works well in small rooms such as your shed or office.

Being in a shed and being carried back and forth is always a risk for the heater to take some physical and sometimes even water damage. The heaters featured above are all designed to have their components within metal casing to protect them from this kind of damage if it does happen.
