you will see a large brass nut with a plastic cover and electrical wire coming from it, normally at the top and to one side of the hot water cylinder, this is the immersion heater,
there are two common lengths, 27 inch and 11 inch.
Also, there are side entry immersion heaters.
Some cylinders have both top and side, the lower, side mounted being the main one and the top acting as a booster for the hot water . The old term of these mountings were, Sussex entry=top mounted, Essex entry= side mounted.
What else can I help you with?
Does water flow from hot to cold?
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
What is a chlorifier?
A chlorifer is a hot water tank heated by an external source. QWERM
How does a hot water tank work?
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.
What is the difference between a calorifier and a chlorifier?
A calorifier is a sealed tank, which heats water indirectly. Usually in the form of a heated coil which is immersed in the water. Commonly known as a hot water tank. A chlorifier is a water tank in which the water is heated via an external source.
What is the function of the expansion tank in a hot water heating system?
To allow for the expansion of heated thot water
How does bladder tank on top of hot water heater operate?
Water expands when it is heated, this expansion increases the pressure. The bladder tank absorbs the extra pressure, protecting the hot water heater.
Why water is generally heated from the bottom?
Warm anything, air or water will rise. Cold water is put at the bottom of the tank through a tube inside the tank. The water is heated and rises and is taken out of the top. The inside of the heater is open, it is just a hollow tube. That is why the hot water gets slowly colder, more cold water is being mixed with the hot in the tank.
Why does a hot water heater need an expansion tank?
A hot water heater needs an expansion tank to accommodate the increase in water volume that occurs when water is heated, preventing pressure buildup and potential damage to the system.
How do gas water heaters work to provide hot water in a household?
Gas water heaters work by using a burner to heat water stored in a tank. When hot water is needed, the burner ignites and heats the water, which then rises to the top of the tank. As hot water is used, cold water enters the tank to be heated, ensuring a continuous supply of hot water for household use.
How does a water heater work to provide hot water in a household?
A water heater works by heating water using a heating element or a burner. The heated water is stored in a tank and is ready for use when needed. When a hot water tap is turned on, the hot water is released from the tank and flows through the pipes to provide hot water for household use.
What is the purpose of a hot water expansion tank in a residential plumbing system?
The purpose of a hot water expansion tank in a residential plumbing system is to accommodate the expansion of water when it is heated, preventing pressure buildup and potential damage to the plumbing system.
Why Cold water is supplied to the bottom of hot water tank?
Cold water is supplied to the bottom of the hot water tank to prevent mixing of cold and hot water. This ensures that the hottest water is at the top of the tank where it can be drawn for use, while the cold water enters at the bottom to be heated by the heating element or burner. This also helps in creating a convection current within the tank for efficient heating.
