How hot does a solar heater make or can make water if you are using it for residential use.?

I looking for either a passive or active system (Pool water heating or hot water used for home).
I know there are different systems out their but I’m looking for maximum temperatures.
My active system in Massachusetts made 120 gallons of 165F degree water today, January 30. It was 20F degrees outside. That’s about the max I can get. The collectors can get up to about 200 degrees, but there is about 15% loss through the heat exchanger, so 165 is about it for the tank.

212 after that it boils. You can start a fire with a rather small magnifying glass, They have power plants which use mirrors aimed at a box on top of a pole that boils water to power a turbine So you can get the water as hot as you want, number of gallons per minute at that temp now thats a different story.

the hottest is to use concave reflectors to concentrate all the energy on the pipe that the water is in.

"Tempering or mixing valves are recommended
for residential water
heating because solar systems typically
heat water to 180 degrees, which
can be a safety hazard especially with
small children. The tempering valve
can be set to 120 degrees and allows
cold water to mix with the hot water
before it reaches the faucet."
that from here..

I agree that 180 would be the max. And yes, it should be bridged to your current system to keep temps reasonable and prevent anyone from getting scalded. In winter, expect around 110. Of course, all of this depends on latitude, time of year, angle to which panels are pitched etc. Don’t know about 212 F, but I guess anything is possible.
