It's all diy - the controller and installation anyway. The heatpump itself is a basic compressor/fan/reversing valve unit that I have added my own controller and control software to.

I describe it all in this post although the software has been upgraded several times since then.

Currently I'm updating the thermostat that goes with the heatpump and have created an app for my phone so I can control the heating directly. The flame on the right is animated to show when the compressor is running, the bar on the left is to increase/decrease the set temperature.
