Have you seen Mr. HD's beard, she will put up with a lot.

(when I visited the IWI was being done and there was a baby somewhere, heard it, never saw it)

You haven't seen my hair recently!

 

Baby?  I knew I'd misplaced something behind the IWI...

 

(The older one turned 18...)

On Monday I had a pre-installation visit to discuss details of trenching and other prep works, for a planned install next month.

 

We often don't put our heating on until December, so I may have already done my last space heating with gas in this house.  Consumption has been tiny since April: https://www.earth.org.uk/saving-electricity-2024.html

 

I am developing a scheme for re-integrating the Sunamp and Intasol with the heat-pump DHW which I think might work well (treating the DHW cylinder as if it is a combi in this arrangement, with the DHW cylinder being 1st priority for Eddi diversion/boost output, Sunamp 2nd),

Modest external groundworks for the heat pump were completed on Friday morning, so it seems this is really going ahead!  I have turned off (low-carbon) grid boost to the Thermino ready for the system to be rearranged...

Internal prep works today including removing the existing cupboard, disconnecting the Sunamp Thermino, and threading round a new T+E from the Eddi heater 2 output for the Thermino in the new control scheme...

Management of how these are being delivered by Octopus seems to gotten worse rather than better over time 

@DamonHD - is the crew employed by Octopus or are they over-promising on sales and hoping to backfill delivery capability by subbing out 3rd party installers without a management structure to operate in this manner?

Everything seems to be working nicely.

 

I have captured current settings/configuration.

 

I shall do some tweaking over the next few days.  Nothing major by the looks of it, certainly less than I had expected.  One thing that I wanted to do does not seem possible (schedule/clock AND external call for heat) but I can live without it, as the external call is reasonably well-behaved.
