How I fitted an Air Source Heat Pump ASHP: Samsung Gen6 5kW

This is my experience self-installing a 5kW Samsung Gen 6 Air to Water Heat Pump and a 150L hot water cylinder in a 200-year-old terrace house in the UK.

UPDATE: Winter performance update video is now live:    • Air Source Heat Pump 1st Winter Perfo...  

The system is monitored using a Level 3 OpenEnergyMonitor Heat Pump monitoring system: https://shop.openenergymonitor.com/he...

Here is real world monitoring data from the system: https://emoncms.org/samsung5kw

This system is also listed on: https://heatpumpmonitor.org

*Clarification*: In the video I mistakenly said the total floor area of the house is 30m2, however this is just for the ground floor. Total floor area including both ground and 1st floor is 70m2.
