Water Heater Installation: Should You Repair or Replace?

by | Sep 15, 2021 | Plumbing

Many people wonder whether they should consider a water heater repair or replace the entire thing and have a new installation. However, no one even thinks about their water heat until something goes wrong, say a cold shower when you have the hot water cranked up or puddles around the heater.


If you have a conventional water heater, you may be able to have it repaired because they are made simply. Regular water will enter your tank and be heated by a gas burner or electrical element. There is a thermostat that regulates temperature, typically between 120 and 140 degrees Fahrenheit. Because the water pressure builds as the water is heated, when you turn on the faucet, the pressure helps send out the hot water.

Because conventional water heaters have few moving parts, there are only a few things that can go wrong, including the pilot light flickers out, circuit breakers are tripped, the heating element or burner fails, the valve sticks or the thermostat breaks.

These types of repairs are usually inexpensive, costing you less than $300 in most cases. If any of those problems occur, repair is usually the best way to go unless the tank is very old or leaking.


Because your water has minerals in it, those minerals can react with the steel over time, corroding the tank. This can cause your water heater to leak, which cannot easily be repaired. However, installation of a new water heater could be better, as they are usually more energy-efficient and can help you save some money on your utility bills. Glass liners are typically used, which means less corrosion and foam insulation is added, which helps with heat retention. Purchasing the tank and water heater installation near St Louis can cost up to $1,500 and more, depending on the type of tank you consider.

Installation of a new water tank may be cause for extra costs, because sometimes building codes require you to upgrade certain items, such as the venting system, drain pans, supply pipes and water heater mounts. Ask your plumber about all the costs, including “hidden” ones so that you are not shocked by a larger bill than you thought you’d have.

Once the water heater has been installed, make sure to keep up with regular maintenance so that it will last longer.
