A coupler is attached to the mount and is positioned nearer to the first end than the second end. The coupler releasably engages a heater. A bracket is attached to the mount and attaches the mount to a post such that the mount is horizontally oriented. A screw is attached to the mount and extends away from the second end. The screw is extendable into and threadably engageable with a tree. The screw has a longitudinal axis lying in a plane is co-planar with the mount.
