- A standard water heater is electrical, liquid propane or natural gas and has a cold water supply that comes down the tank where it enters the tank and heats up. As the water heats up and rises to the top when you turn on the hot water, it leaves the tank and supplies the house. Because the water is constantly being heated in the tank, even when water isn't being used, energy is being wasted (figure A). A water heater's constant use of energy makes it the second largest energy user in the home. A traditional water heater will last 10-20 years.
- In a tankless water heater, there is no storage place for the water. The cold water comes in and goes through four coils (figure B) and comes out heated. It gives you an endless supply of hot water. The cost to operate a tankless water heater is approximately $300-$500 per year. It not only saves energy, it saves space.
Tip: Check your local codes before beginning any project.
- To remove your old water heater, turn off the gas, etc. and then the water. Hook up a water hose to the water heater drain valve (figure C), open the valve and drain the water out.
Expert Tip: Drain as much water as possible out of your tank before you try to move it. It will make your job a lot easier.
- Older houses have a tempering tank. (looks like a water heater). It brings water in from the outside and holds it in a tank to bring it to room temperature, and then it goes to the water heater and heats it.
- Use a rotating pipe cutter (called a close quarter cutter because it can be used in tight spaces) to cut off the cold water tube (figure D). Be sure and have a bucket on hand so that you can catch water that's still left in the pipe.
- Do the same to the hot water pipe. You also need to disconnect the gas pipe. Cap off the gas pipe with a half-inch pipe cap and pipe compound. Tighten with a pipe wrench and channel lock.
Tip: If you are uncomfortable working with gas, hire a contractor.
- Remove the vent (figure E) and then remove the old hot water tank.
In the next segment host Paul Ryan will install the tankless water heater.
