I am a big fan of the Nelson brand. I have had one for 15 years, the other for 12. I have yet to change the thermostat on the 12 year old. My friend, with another brand, changes the thermostat at least every other year, to the tune of about $100 for that brand. The "balance beam" type water valve allows fresh water into the stainless steel bowl as the horse drinks. The bowl is a breeze to remove and clean. The unit is well insulated, and I have put my hand in the water on 100 degree days to find it relatively cool. When I needed tech support, such as when I tried to clean the filter the first time, I called Nelson. You speak immediately to a human, and they have a tech available during office hours to walk you through a concern. A water meter to measure how much your horse(s) drink is available as an extra.

With the horse drinker, The water line is buried deep enough to be below the frost line. In my yard, it is 5' deep. So when the water comes up to the bowl, it is at ground temps. Which for me is 55° summer and 52° winter. Since the water is only in the bowl while the horse is depressing the paddle. There is no thermostat or any concerns about it getting warm or freezing.

I bought an Eco 1 to place in my pasture last fall. I specifically purchsed it because one of the features the dealer told me is that because it was insulated so well the water would stay cooler in the summer. The cold water coming in would stay cool. They were not lying. Thewater is covered with a blue frisbee type thing so sunlight does heat the water. The entire thing is insulated which also helps to keep the water cleaner. If your concern is the water getting too warm. Take my word for it, do not worry

I'm a third on the Nelson's recommendation. We've had ours for ~20 years. Occasional adjusting of the weight system, but otherwise still working perfectly. 4 of them are inside stalls, and 2 are in pasture.
