Default Shut off valve

Hi all... Can anyone tell from this picture, which valve I can turn to shut off the water? I don't care bout the baseboard heating. Just wanna drain the hot/cold water lines without turning off the main.

The red handled ball valve above the tempering valve.

My vote is the yellow handle valve above the mixing valve. That is assuming the cold water continues to the boiler/ water heater.

That is the hot out of the heater. It looks like it's coming from the bottom of the heater. The cold water inlet is on the top.

Not sure what a tempering valve is. The black pipe going across the top is the cold water I believe. the other one coming down states 'hot pottable'. so if I shut off those two, I should be all set. Yes?

You may be in over your head if you can't tell the difference between a gas line and a water line.

The "black" one is copper I believe, the one with arrow? In my experience usually the darker colored copper lines are cold. Without being there its kinda hard to tell you exactly which valves. But only thing you can do is try. Shut them and see if the water is off

Hum, well the other side of the tempering valve is coming from the boiler outlet (labeled) which leads me to believe that its the hot side. Hot water generally does not come from the bottom of a water heater or boiler.

All of the tempering valves I've seen has the hot and cold feeding left and right with the tempered water line out the bottom / top.
