Devola 2.4kW Smart WiFi Patio Heater, model DVPH2400B.
Bought new and only taken out of the box once to test that everything was working correctly. It was then packed straight back into the original box.
The heater is in new, unused condition and works perfectly. It has never been installed or used other than for the brief test.
Selling only because it is too large for what I need.
