Buyer’s Guide: How to Choose a 50-Gallon Water Heater
Not all 50-gallon water heaters are created equal. Here’s what matters most when picking your new unit:
- Fuel Type: Decide between electric and gas. Gas models heat water faster and work in blackouts, while electric are easier to install and maintain.
- Dimensions: Double-check your space—short, medium, and tall models fit different utility closets and basements.
- Energy Efficiency: Look for high Energy Factor (EF) ratings or Energy Star models to lower operating costs.
- Recovery Rate: This tells you how fast the unit reheats water after use. Higher rates mean more hot water for big families or busy mornings.
- Tank Lining & Warranty: Glass-lined tanks resist corrosion. Longer warranties signal better parts and construction.
- Smart Features: Some modern heaters offer WiFi monitoring, leak alerts, or vacation mode for extra peace of mind.
Step-by-Step: Replacing a 50-Gallon Water Heater
-
Measure Your Space
Before buying, check the height, diameter, and location of your current heater. Measure doorways and tight corners for a smooth delivery. -
Choose the Right Replacement
Select a model that matches your home’s fuel type, space, and hot water needs. -
Turn Off Power & Water
Shut off the electricity at the breaker (or the gas valve). Close the cold water inlet valve at the top of the tank. -
Drain the Old Tank
Connect a garden hose to the drain valve and empty the old tank completely. -
Disconnect Plumbing & Power
Carefully remove electrical wires or gas line, and disconnect the water pipes. Have a towel ready for drips. -
Remove and Replace
Move the old tank out (they’re heavy—use a helper or dolly). Set the new one in place, ensuring it’s level. -
Reconnect Plumbing & Power
Attach water lines and, if needed, gas lines using thread seal tape. Reconnect the electrical supply, following all safety codes. -
Fill and Test
Open the cold water valve and a hot tap to bleed air and fill the new tank. Once full, restore power or gas, then check for leaks. -
Dispose of the Old Heater
Recycle or arrange for haul-away—many retailers offer disposal with delivery.
If you’re unsure, always hire a professional plumber or installer for safe, code-compliant results.
