Installing a Tankless Water Heater: What You Need to Know (water heater installation)

Water heaters typically last for about a decade before they need to be repaired or replaced. You can replace your heater with the new tankless-style water heater or just reinstall the same model heater you previously used. A tank-based water heater requires constant heating to keep hot water flowing through your household, where the tankless heater will deliver endless hot water almost instantly. There are several things that should be contemplated before you make the choice to buy a tankless water heater.


Installing a new tankless, or on-demand water heater, in the place of an older tank-style heater, can be difficult. With many considerations including redirecting electrical and gas lines, and whether your gallons per minute flow will adequately heat the water requirements of your home. This project should not necessarily be a do-it-yourself project. Unless you are confident in your abilities, professional consultation should be considered, because an improper install could be unsafe or even leave you with less hot water than you started.

Adjusting Flow

One of your first concerns, before the switch, should be the flow rate that your home needs. Inadequate flow rates do not allow enough hot water to circulate the house and will cause problems heating the home’s water to the desired levels. It’s best to be sure that these requirements are met, or else you face a lot of morning showers with unplanned cold spells. An additional thing to consider is the external temperature of the water needing to be heated. The colder the water is that needs heating, the more the rate of flow is going to be slowed to ensure proper heating of the water. The best tankless water heater overcomes these heating limitations with a dual burner that lets water flow freely.

Replacing Heaters

If you are replacing a gas heater, rather than electric, you are also faced with an even more difficult installation. The excess gases need to be vented properly in a gas system, which requires a larger flue than older style heaters. Resizing the flue is an important safety step for proper venting. The second fact to consider on a gas install is the flow of gas to the heater. More often than not, the gas lines need to be replaced with larger diameter lines to deliver the volume of gas required to properly heat the water.

So, before you run to your local hardware store and purchase the lowest-priced tankless water heater, Speak with a plumber to guarantee that all of your requirements are going to be met by the desired unit. Fully research all aspects of the project as this ensures that you will have all materials and equipment needed and that you are prepared to make the install. This does not just make your job easier during the installation, but shall supply you and your family with all of the hot water that you desire.
