You turn on the faucet. Then you wait. And wait. In many Mesa homes, especially those with long plumbing runs from the garage to a back bathroom or kitchen, hot water can take more than a minute to arrive. It’s frustrating, and it wastes water and energy.
If you’re tired of the delay, there are two solutions you may want to consider:
- Installing a point of use water heater
- Adding a recirculating pump hot water system
What Is a Point-of-Use Water Heater?
A point-of-use water heater is a small unit installed close to a specific fixture, such as a bathroom sink, kitchen faucet, or shower. Instead of relying entirely on your main water heater, it provides hot water right where you need it.
These systems are small tank units holding between two and 20 gallons, though there are some small tankless versions as well.
What Is a Whole-Home Water Heater System?
A whole-home system is what most Mesa houses already have. Whether it’s a traditional tank or a tankless hot water heater, it supplies hot water to every faucet and appliance in the house from a central location. The advantage? Simplicity. One heater serves every fixture, and if you need to do maintenance or replace it, everything is in one place.
The downside becomes obvious in larger homes. When plumbing lines are long, hot water must travel a significant distance before reaching the fixture. During that time, you’re running cold water down the drain.
What Is a Recirculating Pump Hot Water System?
Another option is a recirculating pump hot water system that keeps hot water moving through your pipes so it’s already close to your fixtures when you turn on the tap.
There are two primary types. Some homes have a dedicated return line that continuously circulates hot water back to the heater. Retrofit systems often use the existing cold-water line as a temporary return path and operate on timers or sensors.
Instead of installing multiple small heaters, one pump improves delivery speed everywhere. However, you can use more energy if they run consistently, and there can still be some delays with timer or on-demand units.
Comparing Your Options
Each solution addresses a slightly different need.
| Feature | Point Of Use Water Heater | Whole-Home System | Recirculating Pump System |
| Primary Purpose | Serves one fixture or area | Serves entire home | Speeds delivery from central heater |
| Installation Location | Near sink or shower | Garage or utility area | Near main heater and/or fixture |
| Upfront Cost | Moderate per unit | Standard replacement cost | Moderate depending on plumbing |
| Water Waste Reduction | Very effective at that fixture | None inherently | Reduces whole-home wait time waste |
| Maintenance | Separate maintenance per unit | Single maintenance point | Pump and plumbing components require service |
| Best For | Remote bathrooms or additions | General household use | Homes with long plumbing runs |
If your frustration is limited to one distant sink, a point-of-use system may be ideal. If your entire home suffers from delays, a recirculating pump may provide broader improvement.
Dealing With Mesa’s Hard Water
The water in Mesa is considered hard, which increases the likelihood and frequency of scale buildup in hot water heater tanks and pipes, reducing efficiency in traditional tank heaters or point of use tanks. When sediment settles at the bottom of the tank, it can degrade the heating element.
Recirculating pump systems may also experience scale buildup, especially at connection points and check valves, but a steady flow of water helps prevent buildup in your pipes.
Regardless of the type of system you choose, regular maintenance and flushing are important to get rid of the scale and keep your system operating at peak performance.
When a Point of Use Water Heater Makes Sense
A point-of-use system works well for homes with one fixture that is far from your water heater. It’s also useful in casitas, additions, or converted garages where extending hot water lines would be costly.
If your goal is to solve one isolated delay without modifying your entire plumbing system, this option can be an efficient and practical solution.
When a Recirculating Pump Is the Better Option
For larger households with long plumbing runs throughout the home, a recirculating pump hot water system often delivers a more comprehensive solution. Instead of managing multiple small heaters, one system improves delivery across all of your fixtures. It’s particularly beneficial when multiple bathrooms experience long wait times.
