A few pool updates for anyone that might be interested.
The pool has been great. Had a few pool parties with friends and was quite relaxing. One thing that I have been monitoring is the water temperature. We have been "Enjoying" 39c to 42c weather here in Lampang and the pool water temp had risen to about 30c. Not too uncomfortable but not as refreshing as 25/27c. I have switched pool filtering times to 3am to 7am and this has brought the water temp to 27/28c. Moving the cooler surface water around at night is far more thermally efficient. During the day I let the water temp rise at the top but about 4" down its still cool. I had many who said how will you heat it in the winter, I laughed and said "Winter time the water is perfect, Its not about heating it here, its all about how to cool it"
. The temperature outlook for the next 4 weeks looks to be 39+C. I will see how it trends.
