Deciding Between Water Heater Repair or Replacement

water heater repair

When it comes to the home, the water heater is one of the most important components. It plays a significant role in providing hot water and maintaining comfortable temperatures in the home. But what do you do when something goes wrong and you need to decide between water heater repair or replacement? This is a decision that needs to be made carefully and thoughtfully as it could end up costing a lot of money if done incorrectly. In this blog post, we will explore how to make the best decision when it comes to deciding between water heater repair or replacement, so you can make the most cost-effective decision for your home.

Factors to consider when deciding between water heater repair or replacement

When deciding between water heater repair or replacement, there are several factors to consider. First, the age of the water heater. If it is more than 10 years old, it may be at the end of its service life and require replacement. The second factor is the cost of repair. If the cost of repair is more than 50% of the cost of a new water heater, it makes more financial sense to purchase a new one. The third factor is the availability of spare parts. If the required parts are not available or are too expensive, then the water heater must be replaced. Finally, the availability of a qualified technician and their proximity to the water heater may affect the decision. If the technician is not qualified to repair the water heater or is too far away, then replacement may be the only option.

In addition to these factors, the type of water heater (conventional tank or tankless) should also be taken into account. Tankless water heaters tend to last longer than conventional tank water heaters and offer many advantages. If a tankless water heater is desired, then it makes more sense to replace the existing one rather than repair it.

Ultimately, the decision between water heater repair or replacement should be made carefully, taking into account all the factors mentioned above in order to make the right choice. A qualified technician should be consulted in order to get the best advice and determine the most cost-effective solution.

Troubleshooting Common Issues

Electric Water Heater

The electric water heater is a commonly used residential home appliance that is responsible for heating your water. Water enters the heater via the built-in input pipe at the bottom, and is forced by the built-in heating elements up through the hot water outlet pipe at the top.

Since the water heater is submerged in the water, it must be kept free from damage and corrosion to prevent a build-up of minerals. The anode rod prevents the tank from rusting and is a critical component, so always check this to ensure the rod is in good condition (often indicated by a-colored coating near the top of the rod).

The thermostat on the tank works to regulate the temperature, so check this to ensure it’s working. The thermostat should be set at 60 – 70 degrees.

The safety valve works by monitoring the pressure within the tank and will automatically release water if the pressure exceeds 150 PSI.

The drain valve (also called a pressure relief valve) works by monitoring the pressure within the tank and will release water when the pressure exceeds 60 PSI, which is normal, or when exposed to excessive pressure, such as when the water heater is accidentally knocked over.

The thermostat, safety valve, and drain valve are all located at the bottom of the tank, so check these areas regularly to ensure they are working properly.

Electrical Wiring: Electricity and water don’t mix, so never connect the two together. Instead, have an electrician hook up the water heater directly to your electrical home service.

Gas Water Heater

If a gas water heater malfunctions, homeowners usually contact a Gas water heater repair company to diagnose the problem. Gas water heaters need to be serviced periodically, but homeowners may encounter problems that require immediate attention. Here are some of the most common problems homeowners face with their gas water heaters, and ways to troubleshoot and repair them.

Burners: Gas water heaters use burners to heat water. If the pilot won’t light, the burner may be defective. A gas water heater repair professional can inspect the burners and pilot light to ensure they’re working properly.

Thermostat: The thermostat controls the temperature of the water. If it isn’t working properly, the water may not be heated to the desired temperature. A gas water heater repair professional can check the thermostat and ensure it’s working properly.

Water Pressure: If water flow from a gas water heater is weak, this could be due to a broken pressure relief valve. The gas water heater repair professional can inspect the valve and ensure it’s working properly.

Solar Water Heater

Solar water heaters are gaining popularity. In fact, the rate of installations is increasing. They are energy efficient, charge themselves during the day, and come at low cost. However, solar water heaters have their limitations too. When designing the system, many other factors are considered for sizing the system. Maintenance and repair of the system are often overlooked.

The solar water heater needs regular maintenance to ensure that the system is not damaged. The solar water heater is made up of different parts. The pump, heat exchanger, and circulation pump need to be maintained regularly. The pump circulates water through the system. The heat exchanger heats the water. The circulation pump sends water through the system. If the system is running, the circulation pump sends water through the system.

Like any mechanical system, there is wear and tear. Therefore, the pump needs to be replaced after some time. The heat exchanger also needs to be replaced after some time. The circulation pump also needs to be replaced after some time. If the circulation pump is faulty, the solar water heater will not function. This will lead to water leaking from the solar water heater.

Water Heater Maintenance

When it comes to water heater maintenance, there are a few key elements to consider. First, check your water heaters temperature and pressure relief valve. This valve prevents the water heater from overheating and releasing water. If it’s not functioning properly, your water heater could develop serious problems. Additionally, it’s important to check the anode rod, which helps protect the tank from corrosion. This rod should be checked at least once a year and replaced if necessary.

Finally, make sure to flush your water heater at least once a year to remove sediment buildup. This will help improve the efficiency of your system and reduce the risk of damage. Additionally, be sure to check the water supply lines to make sure there are no leaks or blockages. By taking these steps, you can ensure the longevity of your water heater and reduce the risk of costly repairs.

When Repair is Necessary?

When is it necessary to have a water heater repaired? A water heater needs repairing when it develops a leak. Water heater repair may be necessary when it develops a noise or does not produce enough hot water.

Water heater repair is necessary when the leak cannot be located or repaired. If the water heater is more than 15 years old, the repair costs will be more since a new water heater is more economical.

When should you replace your water heater?

Most water heaters last around ten to fifteen years. A little over seven out of ten homeowners with hot water heaters choose to replace the water heater when the warranty runs out, rather than repair it. An older water heater can suffer from many problems, including:

  • Tank rust
  • Corrosion in the pipes
  • Leaking
  • Not heating water enough
  • Not heating water fast enough
  • Not heating water at all

A newer water heater has lower operating costs than older water heaters. New water heaters are more efficient and use less energy to heat the water.


Depending on the age of your water heater and the condition it is in, you can choose between repair and replacement as your solution. You should also consider the amount of time you have before you need a replacement.

If your water heater is fairly new and in decent shape, you may be able to repair it. This typically will cost less money than a replacement, but there is no guarantee that the repair will be successful.

If your water heater is very old, your best bet is to replace it. Also, if you have just noticed that your water heater is not heating properly or has stopped heating completely, you may be in need of an immediate replacement. In that case, you should hire a professional to replace your water heater as quickly as possible.
