The side mirrors are more for summer mornings and evenings, to capture the side sunlight, but they will also help with midday sunlight in winter. Just a few mins handling aluminium, even with gloves on, is very chilling for the paws.
Just a few readings from the sunboxes today, which are helping the GSHP to operate safely in the plus temperatures range, even on such a cold day.
|from SB down||5.7||5.7||4.8|
|GLoop return to GSHP||6.2||7.2||6.6|
At this time, more heat is being pulled from the SBs than from the Groundloop! The SBs come on if there is a delta-T of 6 degrees, so they only work when there is a clear advantage. There have only been two days so far in this half year when GSHP consumption exceeded 30 kWh.
