Monday 1st June; we have had a lovely weekend of continuous sunshine here in Peterborough.
I think we have a better understanding of the Solarventi solar unit in this weather.
On the control unit I have kept the max. temp. setting needle at a 2 o'clock position, probably 25 degrees. The needle goes from a temp.setting of 15 degrees at 8 o'clock, clockwise on the dial to a setting of 30 degrees at 4 o'clock on the right of the dial.
The outside temp. thermometer reading reached 25. The solarventi unit stopped running early afternoon. It recommenced at some stage late afternoon I think, I assume once the unit had cooled down. The relative humidity measured 21% on the bathroom hygrometer whilst the unit was running. When it stops, the humidity climbs very quickly back to 40+.
We also leave the bathroom window locked-open. We find this balances the extreme drying capability of the solarventi unit with our need for humidity. You can have too much of a good thing.
In future posts I will continue to give results from our solarventi unit, but in addition I will explore the use of solar power in the form of heat pump / inverter units. These units transfer heat from air outside the house to warm the inside of the house. It will be interesting to see how these investments compare.
