3 Tips For Buying A New Tankless Water Heater For Your Home

In this day and age, more and more people are opting for tankless water heaters when building new homes or replacing old tank water heaters. Tankless water heaters come with a lot of benefits, such as hot water on demand any time of day, energy efficiency, and longevity. However, a tankless hot water heater is not inexpensive, so it is important that you purchase the right one. Taking the time to research your options and understand what is available can increase the likelihood that you are completely satisfied with your new water heater for many years to come. When selecting a tankless water heater, keep the following things in mind:


While a tankless water heater does not store hot water the way a traditional tank water heater does, they do come in different sizes. The size of the heater refers to the output of hot water that the heater can produce at any given time. Thus, before you purchase a tankless water heater you will need to think about how much hot water your household requires. You can do this by thinking about the number of people living in your home and the flow rate of your showerheads and faucets in your home, as well as how much water your dishwasher and washing machine use per cycle. Once you have a good idea of hot water demand in your house on a regular day, you can select a unit that is the right size.

Consider the Temperature of the Ground Water

In addition to factoring in how much hot water your household needs, you will also have to consider the average temperature of the groundwater in your area. If you live in an area that has very cold groundwater, especially in the winter months, you will need a tankless water heater that has the capability to accommodate the temperature rise. When you begin shopping for your water heater, you will be able to see what kind of temperature rise a unit can handle by reading the specs. Make sure that you buy a water heater that can quickly heat the groundwater to your preferred temperature.

Gas vs. Electric

Tankless water heaters are available in both gas and electric models. If you are interested in an electric model, you will need to have your electrical system evaluated to ensure that it has enough power; in some cases, a sub-panel may need to be added. When a home already has a gas line, a gas water heater is a good choice. However, it will be important to have a gas tankless water heater installed in an area with proper venting.
