The thermocouple runs from the pilot light to the control valve. One end sits in the flame from the pilot light and the other is screwed into the bottom of the control valve. It is a copper colored wire/tube about twice the size of the lead in a pencil. It should be beside the larger tube that runs from the control valve to the burner. This is only on gas or propane heaters. They use the same type. Electric heaters do not have one.
I do not have a hot water tank, so I have never had a hot water tank flush performed.
The hot water tank might be undersized for your usage.
do they help with hot water tank replacement
how long does it take for hot water after lighting water tank its gas?
No, a hot water tank heats water by itself.
So the steam can rise from the boiler to the hot water tank storage
No, a hot water tank heats water by itself.
You will get warm instead of hot water. There is a tube inside the tank on the cold side that goes to the bottom of the tank and the hot comes directly from the top. Reverse them and you are going to get the cold water that settles to the bottom of the tank. It will not hurt the tank or anything, it just makes for poor hot water.
A hot water tank works by storing and heating water inside an insulated tank using electricity or gas. When a hot water tap is turned on, the hot water is released from the tank and replaced by cold water that is then heated up for future use. This cycle continues to provide a steady supply of hot water for household needs.
The purpose of the hot water tank relief valve is to release excess pressure and prevent the tank from exploding. It functions by opening when the pressure inside the tank exceeds a safe level, allowing hot water to escape and reducing the pressure to a safe level. This helps ensure the safety of the hot water tank and prevents potential accidents.
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
The best methods for effectively cleaning a hot water tank using a hot water tank cleaner involve draining the tank, adding the cleaner according to the instructions, allowing it to sit for the recommended time, and then flushing the tank thoroughly with clean water. Repeat the process if necessary for a thorough cleaning.
