While it’s possible for some homeowners with plumbing and electrical skills to install an energy-efficient tankless electric water heater themselves, it’s generally recommended to have a qualified professional perform the installation. Here are some key considerations to help you decide:
Pros of Professional Installation:
- Safety: Tankless electric water heaters involve both plumbing and electrical work, which can be complex and potentially hazardous if not done correctly. A professional installer will ensure that all safety measures are followed.
- Code Compliance: Local building codes and regulations often dictate the installation requirements for water heaters. A professional installer will be familiar with these codes and ensure that the installation meets all necessary legal and safety standards.
- Proper Sizing: Determining the right size of the tankless unit for your home’s hot water needs is crucial for efficient and effective operation. Professionals can accurately assess your requirements and recommend an appropriately sized unit.
- Optimal Location: Professionals can help identify the best location for the tankless water heater, taking into account factors like venting, electrical connections, and access for maintenance.
- Warranty Coverage: Many manufacturers require professional installation to validate the warranty on the tankless water heater. DIY installations may void the warranty.
Cons of DIY Installation:
- Complexity: Tankless water heater installation involves plumbing, electrical work, and sometimes gas connections. If you lack experience in these areas, it can be challenging to ensure a safe and reliable installation.
- Risk of Errors: DIY installations may result in mistakes or oversights that could lead to leaks, electrical problems, or inefficient operation. These issues can be costly and potentially dangerous to fix.
- Warranty Concerns: As mentioned earlier, many manufacturers require professional installation to maintain the warranty on the unit. DIY installations may jeopardize warranty coverage.
- Code Compliance: If your DIY installation does not meet local building codes and regulations, you may face legal and safety issues.
If you have plumbing and electrical experience and are confident in your ability to perform a safe and code-compliant installation, you can consider doing it yourself. However, it’s crucial to research your local codes thoroughly, obtain any necessary permits, and follow all manufacturer’s guidelines.
In most cases, for the safety, efficiency, and warranty protection of your tankless electric water heater, it’s advisable to hire a licensed and experienced professional plumber or HVAC technician to handle the installation. They have the expertise and training to ensure a smooth and trouble-free installation process.
