Most people think about their water heater only when it fails. It's one of those things you couldn't live without, but as long as it does its job, you ignore it. And when it breaks down, you have no idea what to do. You can replace that old water heater with a tankless, on-demand water heating system that's more efficient and convenient.

Difficulty: Easy
Instructions
  1. Step 1

    Think about endless hot showers. A typical 40-gallon conventional water heater delivers up to 40 gallons of hot water at a time. Then it has to heat up a new batch of water, which can take 30 minutes or more. A tankless water heater heats water on demand continuously. That means you can stand in the shower forever under a constant stream of hot water.

  2. Step 2

    Forget water leaks in your basement. A conventional water heater holds hot water in a tank in your basement. That water is periodically heated so that it maintains a certain temperature. Typically, when conventional water heaters fail, they leak water, 40 gallons or whatever the capacity of the tank, onto your basement floor. A tankless water heater doesn't store water, so there's no possibility of a basement flood, even if the water heater fails or malfunctions.

  3. Step 3

    Consider the energy savings. A conventional water heater heats water regularly to maintain a certain temperature in the tank. Unless you shut the heater down when you're on vacation, it even heats water when you're not home. You save a considerable amount of energy with a tankless water heater because it heats water only when you ask for it. When you turn on your hot water faucet, the tankless heater heats the water. As long as the faucet is off, like when you're sleeping, the heater isn't running.

  4. Step 4

    Spend your rebate money. Due to the energy savings associated with tankless water heaters, rebates are available when you install one in your home.

Tips & Warnings
  • Seek professional help when choosing just the right tankless water heater for your house.
  • Have your on-demand water heater installed by an experienced professional.
