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.
Times | 1100 | 1145 | 1215 |
SB temp | 23.0 | 22.2 | 21.0 |
Air temp | -6.9 | -6.9 | -6.9 |
GSHP outgoing | 3.7 | 3.4 | 3.0 |
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.
Very informative. Thanks.
