0  comments

If your home has a gas hot water heater, you know how important it is to have a reliable one. They don’t last forever, though, and eventually you’ll need to replace it. Here’s how to do it.

First, shut off the gas supply to the old unit. Then, disconnect the water lines and power supply. Next, remove the vent pipe and exhaust flue from the unit.

Finally, unscrew the unit from its platform and lower it to the ground.

Gas Water Heater Installation

  • Turn off the gas to your hot water heater
  • This is usually done at the main gas shutoff valve for your home
  • Disconnect the cold water inlet pipe from the tank
  • Drain the tank by attaching a garden hose to the drain valve and running it to a nearby floor drain or outside
  • Remove any anode rods from the old tank and unscrew the fittings that hold it in place, then lift it out of its location
  • Place your new hot water heater in the same location and reattach all of the pipes and fittings, making sure they are tight so there are no leaks

Gas Water Heater Replacement Cost

Most homeowners don’t think about their gas water heater until it’s time for a replacement. Then they’re faced with the decision of whether to repair or replace the unit. The cost of replacing a gas water heater depends on several factors, including the type of unit, the size and location of the unit, and the installation costs.

The average cost to replace a 40-gallon gas water heater is $1,000 to $2,500. The average cost to install a new gas water heater is $600 to $800. The price of the unit itself ranges from $400 to $1,200.

These prices do not include the cost of professional installation. When deciding whether to repair or replace your gas water heater, consider the following: – The age of your current unit: If your current unit is more than 10 years old, it may be time for a replacement.

Gas water heaters have an average lifespan of 8 to 12 years. – The efficiency of your current unit: Older units are less efficient than newer models. Replacing an older model with a newer one can save you money on your energy bills over time.

– The condition of your current unit: If your unit has extensive damage or is leaking, it’s probably time for a replacement rather than a repair. – The cost of repairs vs. replacement: In some cases, repairing your existing gas water heater may be more expensive than replacing it with a new one. Be sure to get estimates from multiple plumbers before making a decision.

Can You Replace a Hot Water Heater by Yourself?

If you’re handy with tools and comfortable working around water and gas lines, you can replace a hot water heater by yourself. Here’s how: 1. Shut off the power to the water heater.

If it’s a gas water heater, shut off the gas supply as well. 2. Drain the old water heater tank completely following the manufacturer’s instructions. You’ll need a garden hose for this step.

3. Disconnect the wires from the old thermostat and disconnect the pipes leading to and from the tank using two pipe wrenches. Remove any anode rods from inside the tank with a socket wrench (these are often located near the top of the tank). 4. Place your new water heater in position, making sure that all connections match up correctly with their respective ports on the new unit before securing it in place with bolts or straps (again, follow your manufacturer’s instructions).

Reconnect all wires and pipes, being careful not to over-tighten them, then turn on both your power supply and your gas supply (if applicable). Test everything to make sure it’s working properly before calling it a day!

How Often Should a Gas Water Heater Be Replaced?

A gas water heater should be replaced every 8 to 12 years. If it is used frequently, it may need to be replaced sooner. Inspect the unit regularly for signs of wear and tear, such as rusting or leaks.
