How does the hot water tank work?
The water in a direct hot water cylinder is heated by an immersion heater within the cylinder. An indirect hot water cylinder requires an external device to generate the hot water, such as a boiler. An unvented cylinder doesn’t need a cold water tank because water enters it from the mains supply.
Do water heaters give off heat?
The heating mechanism, either a burner or an element, stays on until the water reaches temperature. As the water heats, it rises to the top of the tank. The heat-out pipe is located near the top of the tank.
How does a gas hot water tank work?
In a gas heater, a gas-powered flame at the bottom of the tank sends hot air up a chimney that runs through the middle of the heater. This chimney transmits heat to the water, and when you turn on the hot water tap, more cold water flows into the heater, displacing hot water up the hot water pipe.
How big does a hot water tank need to be?
As water is heated, it can increase in volume by up to four per cent. The expansion tank can absorb this extra water volume so that the pressure doesn’t build up in the system. You’ll need an expansion tank with all cylinders that are 30 L or bigger.
What does it mean when your hot water tank is leaking?

How does a vented cylinder hot water tank work?
It could be a vented cylinder or an unvented cylinder. The main difference is that one requires a cold water tank and one doesn’t. A vented cylinder relies on a cold water tank to feed water into the cylinder for it to be heated by either the boiler or an immersion heater.
