There is no shut off valve. But you can by pass the heater core by disconnecting the 2 hoses going to the heater core. And connecting them together. The only problem with this is that you won't have any heat in the winter.
It partly depends upon what sort of heater it is, but if it's a car heater, the valve alters the amount of hot water (from the car's cooling system) entering the heater matrix. This would also be true of a water-filled central heating system.
The hot water valve should always be open, so the hot water can exit the heater into the system. If your actually meaning opening the drain valve on the bottom of theater, the water in the heater will drain, starting with the hot water stored there, and then the cold water that is entering the tank to replace it will simplt flow out the bottom before being heated. Dpending on where the heater is located will denepnd on how much of a mess the ensuing flood will be.
It does not have a water flow valve in the heater plumbing.It does not have a water flow valve in the heater plumbing.
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.
Check that there isn't water around the water heater first, which would mean that turning it off and closing the water valve would be a good idea. Then, check the fuse box to see if the power has tripped--that is if it is an electric water heater.
A TNP valve is a temperature and pressure valve found on a water heater.
It is already available.
No, cold wter enters the water heater at the bottom of the tank, right where thee valve is.
Yes! Connect a garden hose to the output valve of the water heater and open the water heater valve to put hot water into the kiddie pool. This is the fastest way to warm a children's pool.
There isn't a water control valve.
You would need to specify the size of the heater
The heater output temperature is regulated by airflow control doors inside the dash, not a water valve.
