Week 50, Day 1

Week 50, Day 1:

  • A bit more second-fix plumbing, installing the WC and the flush plate for the concealed cistern in the Master Bedroom En-Suite and some other work on the plumbing systems
  • More second-fix electrical, including commissioning the ImmerSun Solar PV diverter which is connected to the immersion heater
    • This monitors the amount of on-site generation (Solar PV power) being exported to the Grid and runs the immersion heater on something equivalent to a dimmer switch in order to use as much self-generated power as possible even if not generating the full 3kW required to run the immersion at full power
    • This is expected to meet most, if not all, of the hot-water demand in the summer months, instead of running the heat pump
    • Similar devices are available from other manufacturers but I chose the ImmerSun because it seemed to be the most mature solution on the market and has the best remote control and monitoring integration, uploading data to The Cloud at http://www.myimmersun.co.uk/
    • Unfortunately, just after I’d bought the ImmerSun unit and its optional remote monitoring add-on, the company who manufactures the units (and runs the websites) went into administration so I was kicking myself for not going for an Open Source solution such as the one from the Open Energy Monitor Project and wondering whether the radio communications between the main unit and the monitoring add-on might use a standard protocol I could pick-up with an RFXCOM transceiver
    • Fortunately the company has now been rescued and the websites are back up and running
