Point-of-Use or Whole-House Tankless Water Heaters?

You’ve likely already heard about the benefits of tankless water heaters, how they’re up 34% more efficient and have a longer lifespan than conventional storage tanks. What you might not know is that there are two options when it comes to demand-type water heaters: whole-house and point-of-use.

Let’s break down the differences.

Whole-House Tankless Water Heater

As the name suggests, this is one unit that serves the entire home. Depending on how large your home is, how many hot-water points may be in use at any given time (i.e. shower, dishwasher, kitchen sink), a whole-house system may or may not be adequate. A professional plumber can help you determine if this system will meet your needs. However, in most cases, we find that a single system does the job for the average household.

Point-of-Use Tankless Water Heater

This type of water heater is set up so that there is one unit serving a certain room — a master bathroom with a jetted tub, for example. You may need two to three of these heaters, wired to your electrical system, for multiples zones around your home. The benefit of this configuration is that you’re getting hot water directly from the source. These types of water heaters should be installed as closest to the location that needs hot water as possible for the best results. The less hot water has to travel from Point A to Point B, the more efficient your plumbing system is.

Bottom line: We’re experts in tankless water heaters. We’ll be happy to help you determine which type of system is best for your home. Keep in mind, no matter which route you take, either a whole-house or point-of-use tankless water heater will save water and money. To schedule an appointment, call 949-355-1575.
