Summer is over and, as usual, long and hot.
For the first time I had the under floor cooling running properly and so have some data, obviously no comparisons as I've not been running air conditioning previously so don't have comparisons to see if there is a saving.
The house was definitely very comfortable though, with temperatures varying between 24 and 26 degrees, outside temperatures in the mid to upper 30's and touching 40 a couple of times.
Initially I ran the unit 24/7 but had problems with dew forming.
To overcome problems with floor dew I ran the cooling on a 12h cycle, from 8am to 8pm and we had the ceiling fans running at a slow speed. This, apart from one or two days, prevented any dew forming. There wasn't too much impact on the house temperature.
The water temperature in the floor was typically around 17C
Electricity use averaged 23KWh per day, around 2.74 euros (our electric is 0.119 euros per KWh)
In total we used 2142KWh.
