As a homeowner, you may have faced the dilemma of choosing between repairing or replacing your water heater. It can be a daunting task, especially when you are not sure which option is best for you. In this blog post, we aim to help you navigate this challenge by providing you with essential information on what to look out for and the factors to consider before deciding to repair or replace your water heater.

Age of your Water Heater

The age of your water heater is a critical factor to consider when faced with the decision to repair or replace it. Typically, water heaters last between ten to fifteen years. If your water heater is over ten years old, repairing it may not be a good idea as it may continue to require constant repairs. Replacing it would be a better long-term solution to save on repair costs.

Frequency of Repairs

If your water heater frequently requires repairs, it may indicate that the unit is failing. When the cost of repairs outweighs the cost of replacing the unit, it’s time to consider replacing the unit rather than continuing to repair it. Having a professional plumber in to inspect the water heater unit can help provide valuable insights on whether repair or replacement is the better choice.


Another factor to consider is the efficiency of your water heater. Older water heaters tend to have lower energy efficiency compared to new ones, leading to increased energy bills. Replacing your water heater with a newer, more energy-efficient model can significantly reduce your monthly utility bills. Therefore, if your current water heater is not energy efficient, it may be time to consider replacing it.

Type of Water Heater

The type of water heater you have affects your decision to repair or replace it. Conventional storage-tank water heaters may be less expensive to repair, while tankless water heaters may cost more to repair. Tankless water heaters are typically more expensive to replace, but they are more energy-efficient and require less maintenance. Therefore, consider the type of water heater you have when deciding whether to repair or replace it.


Lastly, the cost of repair and replacement is a critical factor to consider. If the cost of repairing your water heater is close to the cost of replacing it, then replacing it is the better option. Replacing a water heater is more expensive, but it can save you money in the long run on maintenance, repair, and energy costs.


In conclusion, choosing between water heater replacement or repair is not always straightforward. Several factors influence this decision, including the age of the water heater, the frequency of repairs, efficiency, the type of water heater, and repair costs. When faced with this decision, it’s advisable to seek professional guidance from a licensed plumbing professional to make an informed choice. Remember, a more energy-efficient water heater can save you money on your utility bills and significantly reduce your environmental impact.
