Purchased as a primary heat-source for my garden office and once set up, is a really effective and simple device.Pairing the remote is a bit tricky if you try and follow the manual (page 28 for this model's LCD screen). Once you establish that the buttons on the remote are not correctly labelled and understand how to set the heater to the "Start-Up" mode (which is effectively a Settings" menu), it's a much easier operation.I now have a fully functioning heater, working remote and at a fantastic (offer) price!Note - if you use Fibre Glass Exhaust Wrap on the exhaust, make sure you do it outdoors as the material can smoke quite a lot for the first 20 mins or so. This is normal but not great when in an enclosed space!
