Octopus Energy Daikin Heat Pump Installation - Day 5
The day has finally come for our Daikin Altherma 4kW (EDLA04E2V3) heat pump to be installed. The whole process has been managed by Octopus Energy. You can follow the journey so far (My heat pump journey with Octopus Energy - Part 1, My heat pump journey with Octopus Energy - Part 2 - Planning Permission)
Today was the final day of the install. I hardly saw the team as they were just finishing off some lagging, installing a cover for the old gas vent, and a few other jobs. Overnight the Legionella cycle had successfully run. The electricity cost when I woke up was £2.07, as I write this it is 53p after the export. Our gas is still connects as we have a gas hob.
It is interesting how the heat pump works. It has a setting called reheat. As soon as the tank goes below 43c, it will get it back to 43c. Overnight it will then heat it to your desired temperature. That can be either be 45c (eco) or 48c (comfort). We have set it to comfort. We just ran a bath and the tank went from 27c to 44c in twenty minutes.
Below are the final pictures of the installation. I hope you found these posts over the past five days helpful. I can highly recommend Octopus Energy as your heat pump installer.
Front power junction box. Cables are run from here to the back of the house. They did a nice job without having to go up and over the front door
Cable run across the front door
Cable run kept nice a low and as hidden as possible

The cables from the front are run to this box at the back
