Yes. Hiring a licensed plumber is strongly recommended. They expertly manage complex water and gas connections, ensure your setup passes local safety codes, and protect your manufacturer warranty.

To prevent Legionella bacteria (which causes Legionnaires' disease) from multiplying, your water heater should be set to 140°F (60°C). However, because water at this temperature poses a severe scalding risk, it must be mixed with cold water using a Thermostatic Mixing Valve (TMV) to deliver safe, warm water to your taps.
Legionnaires' disease is usually contracted by breathing in small, contaminated water droplets (mist or aerosol) that contain Legionella bacteria. It is not spread person-to-person.
Plumbers most highly recommend Bradford White, A.O. Smith, and Rheem. These brands are heavily favored because they are highly reliable, have readily available replacement parts, and use superior internal components compared to budget models.

Professional installation costs to replace a water heater
The more hours of electrical, carpentry and plumbing work that are required for your installation (for example, installing new electric, water or gas lines or drywall), the higher your total water heater replacement cost.
Water leaks are perhaps the most common type of water heater issue you'll face. Any water heater will start to leak eventually, as by nature water will eventually corrode your tank and create microscopic cracks or fractures. However, this isn't always a sign that your tank is what's leaking.

With a 40-gallon tank, your hot shower will typically last about 10 to 20 minutes. The exact duration depends heavily on your showerhead's flow rate and the temperature you set your water heater to.
PMRs for malignancies of the stomach, kidney, brain, and lymphopoietic system were also elevated, especially among plumbers. Chronic rheumatic heart disease, emphysema, liver cirrhosis, and all external causes of death were the major non-cancer causes with significantly elevated PMRs.
