Here’s a comprehensive look at what’s involved in a water heater installation, whether it’s a traditional tank or a tankless system.

Water Heater Installation Process

1. Choosing the Right Water Heater

• The installation process begins with selecting the correct type and size of water heater. Considerations include:
  • Type: Tank or tankless, gas or electric.
  • Capacity: Tank water heaters typically come in 40, 50, or larger gallon capacities, while tankless units are sized based on flow rate (gallons per minute).
  • Energy Efficiency: High-efficiency models reduce energy bills and may qualify for rebates or tax credits.

2. Removing the Old Unit (if applicable)

• For replacement installations, the old water heater is disconnected, drained, and safely removed.
• Disposal of the old unit may incur an extra fee unless the installer includes it in their services.

3. Preparing the Installation Area

• The installation area is prepared according to local codes, which may include:
  • Ensuring proper clearance and ventilation for gas heaters.
  • Leveling the floor or creating a stable platform for tank heaters.
  • Checking for any potential leaks or structural issues.

4. Installing a Drip Pan (for Tank Models)

• For traditional tank heaters, a drip pan may be installed underneath the unit to catch any potential leaks or overflow.
• The pan is typically connected to a drain to safely remove any excess water.

5. Connecting Water Lines

• The water supply lines are connected to the new unit with flexible connectors or hard piping, depending on the local code and plumbing setup.
• In many cases, dielectric unions or anti-corrosion fittings are used to prevent rust at the connection points between copper and steel.

6. Setting Up the Venting System (for Gas Models)

• Gas water heaters require proper venting to safely exhaust combustion gases.
• This can involve installing a vent pipe or flue through the roof or wall and ensuring proper vent diameter and slope for safety.
• High-efficiency gas units may use PVC venting systems for direct venting out a wall.

7. Connecting the Gas Line (for Gas Models)

• For gas water heaters, the gas line is connected with care, using flexible gas connectors or hard piping.
• The connection is checked for leaks using a gas leak detection solution or electronic tester, ensuring safety.

8. Connecting Electrical Components (for Electric Models)

• Electric models require connection to a dedicated electrical circuit.
• The technician may wire the heater directly to a circuit or use a power cord, depending on the model and local codes.

9. Installing a Temperature & Pressure Relief Valve (T&P Valve)

• The T&P valve is a safety device that releases water if the pressure or temperature becomes too high.
• The valve is connected to a discharge pipe that directs any released water safely to the floor or a drain.

10. Filling and Testing the Unit

• Once all connections are secure, the tank is filled with water, and the system is checked for any leaks.
• For gas models, the pilot light is ignited, or the electronic ignition system is tested.
• For electric models, the power is turned on, and the system is monitored to ensure proper heating.

11. Setting the Thermostat

• The technician adjusts the thermostat to the recommended setting, which is safe, energy-efficient, and helps prevent scalding.

12. Testing the System for Proper Operation

• The water heater is tested to confirm it’s heating water correctly and that all connections are secure.
• The technician will ensure the temperature is steady, the pressure relief valve functions correctly, and there are no unusual noises or issues.

13. Cleaning Up and Final Checks

• The installation area is cleaned up, and all waste materials, including the old unit, are removed.
• The technician will walk the homeowner through basic operation, safety features, and maintenance tips, ensuring they know how to use the new system.
