Installing a new water heater requires careful planning to ensure safety, efficiency, and long-term performance. Before installation, confirm the correct fuel type (electric, gas, or tankless), capacity, and local building code requirements. Shut off the power, gas supply, and water lines before removing the old unit. Proper placement, ventilation, pressure relief valve installation, and leak testing are essential to prevent hazards and costly repairs. Many jurisdictions require permits and professional inspection. Homeowners should also consider energy efficiency ratings and maintenance needs. For gas or high-voltage systems, hiring a licensed installer is strongly recommended.
