Proper installation of a water heater tank is crucial for its optimal functioning and performance. You should get it installed by a reliable and experienced technician. Expect to pay between  $600 to $1000 on average for hot water tank installation.

On average, a water heater tank lasts for 8 to 10 years and usually needs to be replaced after ten years. But if you find signs such as rust in water or water leakage, noisy operation, or water not heating rough, you should call a professional to diagnose the exact problem. 

The size of the hot water tank for your home depends on the system’s consumption rate, usage, and heating capacity. For two-person use, a water tank with between 23 and 36 gallons of storage capacity will work. Select a tank with a storage capacity of 46 to 56 gallons for three to five people and a water tank with a storage capacity of more than 56 gallons will work for more than 5 people.

Water heater tanks can use fuel sources such as propane, natural gas, electricity, or fuel oil. You can choose anyone, but it is advised to select the affordable and readily available one.
