Heat trap

Imagine that you have a mug of hot chocolate. When you first make it, the hot chocolate is very warm, but over time it starts to cool down. This is because the heat has been able to escape from the mug and into the air around it.

Now imagine that you put a lid on the mug. This will help to keep the heat trapped inside the mug, so the hot chocolate stays warmer for longer.

Heat traps work in a similar way. They are devices that are used in hot water tanks to prevent heat from escaping. When hot water is stored in a tank, the heat can escape through the walls of the tank and into the air around it. This means that the water in the tank will cool down over time.

But if a heat trap is installed on the tank, it can help to keep the heat trapped inside. A heat trap can be made up of different parts, but often it will have a valve that will prevent hot water from flowing out of the tank unless it is being used. This helps to keep the heat inside the tank for longer, so the water stays hotter.

In summary, a heat trap is a device used in hot water tanks that helps to keep the heat inside the tank for longer, so the water stays hotter. Just like a lid on your mug of hot chocolate helps it stay warm, a heat trap helps to keep the heat trapped inside the tank.
