Water Heater Choices – Is an On-Demand Water Heater Right for You?

Replacing a water heater can be a costly event. Aside from the water heater itself, if your old water heater goes out with a bang, you could be Water heater diagramfaced with damage and repair expenses as well. When it comes to selecting the right water heater for your home it is important to consider several things: your budget, your conservation goals, your space, and your usage.


On-demand water heaters tend to have a higher upfront cost than their tank storage predecessors. However, it is important to note that on demand water heaters cost less to operate and less to maintain. In addition, on-demand water heaters have a higher life expectancy and are easier to repair vs. tank storage water heaters.

Before and after changing water heaters


If space is an issue, then an on-demand water heater is the perfect choice. They take up less space than their bulkier counterparts, and are less intrusive. For smaller spaces, on-demand water heaters are a great solution.


One of the downfalls to on-demand water heaters is, a single water heater might not be able to keep up with heavy usage. For example, a family of 4 who are running the dishwasher and the washing machine at the same time, and then trying to take a shower, might need more hot water than one on-demand water heater can produce. It is recommended to have more than one on-demand water heater for high volume. One dedicated to appliances, and one dedicated to bathing. Of course, the more people in the household, the more hot water will be used, so when considering on-demand water heaters it is important to be realistic with your usage.
