Installing Your Own Water Heater: Pros & Cons


Installing your own water heater can be a cost-effective option for some homeowners, but it also comes with certain risks and challenges. Here are the pros and cons of installing your own water heater:


  • Cost Savings: DIY installation can save you money on labor costs, which can be a significant portion of the total installation expense.
  • Flexibility: You can choose the installation date and time that works best for you, eliminating the need to schedule and wait for a professional plumber.
  • Learning Experience: Installing your own water heater can be an educational experience. It allows you to gain knowledge and hands-on experience with your home’s plumbing system.
  • Immediate Repairs: If you encounter a minor issue with your water heater, you may be able to address it immediately without waiting for a professional.


  • Complexity: Water heater installation can be complex, especially if you’re not experienced in plumbing. Mistakes can result in leaks, inefficiencies, or even safety hazards.
  • Warranty Concerns: Many water heater manufacturers require professional installation to maintain the warranty. DIY installation may void the warranty.
  • Safety Risks: Gas water heaters can pose safety risks if not installed correctly. This includes gas leaks and carbon monoxide exposure. Even electric water heaters can be dangerous if not properly installed.
  • Permits and Codes: You might need to obtain permits and adhere to local building codes when installing a water heater. A professional plumber would be familiar with these requirements.
  • Time-Consuming: DIY installation can take much longer if you’re not experienced, potentially leaving you without hot water for an extended period.
  • Tools and Materials: You may need to purchase or rent specialized tools and materials for the installation, which could add to the overall cost.
  • Lack of Expertise: Professionals have the experience and expertise to ensure that the water heater is correctly installed, sized, and vented, which can impact efficiency and safety.
  • Potential for Future Problems: If the water heater is not installed correctly, it can lead to problems down the line, which could be more expensive to fix.
  • Resale Value: A DIY installation may not be as appealing to potential homebuyers as one done by a licensed professional, which could impact your home’s resale value.

In summary, while there are potential cost savings and educational benefits to installing your own water heater, it’s a task that should only be attempted if you have a good understanding of plumbing systems, the necessary skills, and the proper safety precautions. If you’re unsure about your abilities, it’s usually safer and more practical to hire a licensed professional to ensure the job is done correctly and safely. Additionally, professional installation often comes with the assurance of warranty coverage, compliance with local codes, and long-term reliability.
