Hot Water Tanks: What You Need to Know

By arya

A cold shower, especially during the cold weather. However, you can make the situation better by installing a water heater or geyser. Warm water is preferable for a shower or washing hands than cold water. If you haven’t thought about it, this post will inform you what you need to know about hot water tanks.

How a Hot Water Tank Functions

Hot water tanks are either gas or electric. A gas heater is gas-powered by a flame at the tank’s bottom then hot air goes up a chimney that goes through the middle of the heater. The hot air in the chimney is then transmitted to heat the water. When the water is used, more cold-water flows into the tank to replace the used amount, and the cycle continues. 

As for electric water heaters, they function the same, but the heating method is electric. They are fitted with heating elements inside the tank. Both water heaters have a part that rusts faster and it acts as a shield to prevent the tank from rusting. Therefore, the hot water tank doesn’t rust. 

What to Do When Your Hot Water Tank is Leaking from Top or Bottom

Although the material that makes hot water tanks doesn’t rust fast, your tank can leak from the bottom or top. During routine maintenance, you turn the drain valve to allow water to drain, and leaking may happen, but the issue can be fixed quickly. 

Sometimes you might see the water from normal condensation on the water heater. In this case, the easiest way to fix the leak is to turn up the thermostat. If water leaks from the pipes, you can use a wrench to tighten the joints, and the problem will disappear. 

Check the pipes around the top of your hot water tank leak from the top. The tank is a pressurized system, and any loose connection at the top can cause leakage. Dry the area thoroughly and ask someone to turn on the hot water faucet as you watch if water beads will form around those pipes.

Suppose the pipes at the top aren’t leaking the temperature-pressure valve could be the problem. When under excess pressure, the valve can open alone while releasing pressure in the tank. A buildup of tension in the tank is dangerous as it can lead to an explosion. In this case, you must call a professional maintenance team to help release the pressure and stop the leak. 

Factors to Consider When Purchasing a Hot Water Tank

Hot water tanks need frequent maintenance to ensure they operate well and serve the intended purpose. However, before we get to care, here are the factors to consider when buying a hot water tank. 

  • Capacity
  • Quality of the tank and heating elements
  • Energy consumption
  • Area of installation


Routine checks on your hot water tank will help arrest any issues promptly. Regular maintenance will keep the tank in good shape for a long time until the day you may want to replace the tank. But don’t forget to immediately get professional help for any problems you notice with your hot water tank because delays can be hazardous and costly.
