As you are looking at it, the hot is on the left.
The isolation valve should (must) be placed on the cold water side (and/or the return side), entering the water heater. Placing the isolation valve on the hot or outlet side of the water heater has the potential of creating a bomb.

Standard instillation of a washer identifies the valve s as hot on the left, cold water on the right. In any water instillation, the standards are hot on the left and cold on the right.
A furnace does NOT have water... A boiler has water .. NICE trick question

The side effects to exercising in hot water are blood circulation problems.
You know it by touching and feeling the pipes on the hot water side; if they are hot, there is water running through the pipes and obviously the heater valve is open on hot side.

Usually there is a shut off valve right above the water heater on the cold side. There can be one on the hot side to so that the heater can be removed without having to drain the system.
An isolation valve on the hot side of the domestic water system should only be installed IF there is an expansion tank on the hot water system. This is because if both the inlet and outlet of the water heater are shut off with no expansion tank, the expansion caused by the heating and cooling of the water can cause the pipes to burst. Usually there is only a shut off on the cold inlet side of the water heater. To isolate the hot side of the system you would shut off the cold inlet to the water heater and drain down the hot side. Note that if valves and seals are old and leaking, you will get cross over from the cold to the hot in some of the fixtures themselves, necessitating the need to shut off the cold and drain down the entire system.

Check piping. Make sure cold line going into cold side of water heater and hot side coming out hot side. Cold feed for water heater should come off main cold line. Make sure valves are open to and from water heater.
It would depend on how the water was heated. Tankless Coil, there should be a valve on the side of the coil, that has a knob on top, that is your mixing valve and should be used to adjust water temp. Indirect Hot Water Tank, it is connected to boiler through piping, but does not have it's own burner...should have a box on it, (aquastat), that will adjust the temp of your hot water, likewise with a Direct Fired Hot Water Tank, which is the same as mentioned above, but with it's own oil burner.
