I drained, cleaned, and refilled the hot tub last week and since it's been up in the low 80s the past two days here in western NC the backyard spa got up to 88 degrees today just from the sunshine. I topped it off to 96 with the electric heater and had a nice soak tonight. Once the hot tub is put into service the woodstsove usually goes on hiatus until next autumn. I feel for you all who live in areas where you are still fighting the cold or even some snow, but you too will one day again be enjoying the warmth of the sun. Less than a week ago we dropped down below freezing over night!
