The state water heaters UPVS-110Y-100 Electric Tankless Water Heater is a point-of-use, on-demand hot water solution designed for locations that need compact, efficient, and continuous hot water without a storage tank. It uses a thermostatic design to regulate output and can be configured for lavatory or emergency eye wash applications, making it a strong fit for commercial restrooms, labs, healthcare spaces, and other controlled-use environments. Because it heats water only when needed, this electric tankless model helps reduce standby energy loss while saving valuable wall and floor space.

This unit is best suited for facilities that need consistent hot water near the fixture and have the electrical capacity to support a dedicated tankless heater. Common use cases include single-sink handwashing stations, commercial point-of-use installations, and specialty applications where reliable temperature control matters more than whole-building hot water delivery. The estimated price range is typically in the mid-hundreds to low-thousands depending on seller, region, and installation requirements, and availability is generally through plumbing supply distributors, commercial equipment retailers, and State Water Heaters channels.

Compared with traditional tank-style heaters, the state water heaters UPVS-110Y-100 Electric Tankless Water Heater offers faster response at the point of use, no recovery tank, and no venting requirement. Its compact footprint and wall-mounted design make it especially attractive in tight utility closets and service areas where space is limited.

Setup Guide: How to Install and Configure the Unit

Installation should be completed by a qualified electrician or licensed plumber familiar with electric tankless water heater requirements. Begin by confirming that the electrical service can support a dedicated 277 V, 40 amp circuit with #8 AWG wiring. Mount the heater securely on a wall near the fixture to minimize heat loss and wait time. Connect the 1/2-inch NPT water lines, then verify that all fittings are sealed and leak-free before powering the system.

After installation, fill and purge the unit to remove trapped air. Never energize the heater until it is fully filled with water. Configure the thermostatic settings based on the intended use, selecting lavatory or emergency eye wash mode as needed. If the system is not producing the expected temperature, confirm inlet water temperature, electrical supply, breaker status, and flow conditions. Safety precautions are critical: keep the unit dry during service, follow local electrical codes, and avoid operating the heater without proper grounding.

There is no pairing or wireless connectivity required for this model. Any setup is mechanical and electrical, so the most important configuration steps are correct sizing, secure wiring, and accurate temperature selection.

Troubleshooting Common Problems with Electric Tankless Water Heaters

If the unit delivers lukewarm water, check whether the flow rate exceeds the heater’s capacity or whether the incoming water is unusually cold. Reduced temperature can also result from undersized wiring, an incorrect breaker, or poor voltage supply. If there is no hot water at all, verify that the circuit breaker is on, the unit is receiving power, and the heater is completely full of water. Air in the lines can prevent proper operation after installation or maintenance.

No hot water: Confirm power, breaker status, and water flow.
Water too cool: Reduce flow, check incoming water temperature, and verify load sizing.
Intermittent heating: Inspect wiring, voltage, and terminal connections.
Leak at fittings: Tighten connections and recheck 1/2-inch NPT seals.
Overheating concern: Ensure correct mode selection and proper installation clearances.

There are no widely published user-facing error codes listed for this model in the available product details, so troubleshooting is usually based on power, flow, and installation checks. Preventive care includes annual inspection, periodic leak checks, and confirming that the heater is not operating beyond its rated application. The product includes a 5-year limited warranty, and support is typically available through State Water Heaters customer service, the official support portal, and authorized contractors. For help, use the model number and serial number from the rating plate when contacting support.

Faqs

How do I install the state water heaters UPVS-110Y-100 Electric Tankless Water Heater for a point-of-use application?

Start by confirming the unit is mounted close to the fixture it will serve, since this model is designed for point-of-use use. It mounts on the wall, does not require venting, and uses standard 1/2-inch NPT water connections. Before powering it on, verify the electrical supply matches the unit’s requirements and that the circuit is properly sized. For best results, have a licensed electrician and plumber handle the setup.

What electrical requirements does the state water heaters UPVS-110Y-100 Electric Tankless Water Heater need?

This model requires a 277-volt electrical supply, a 39.71-amp draw, a 40-amp breaker, and #8 AWG wire size. That means it is not a simple plug-in appliance and should be connected to a dedicated circuit. If the electrical service is undersized, the heater may not perform correctly or may trip the breaker. Always confirm compatibility with your home or facility panel before installation.

Why is the state water heaters UPVS-110Y-100 Electric Tankless Water Heater not heating water fast enough?

Slow heating usually happens when the unit is undersized for the demand, the incoming water is too cold, or the electrical supply is not meeting the heater’s requirements. This model is designed to provide continuous hot water when sized appropriately, so matching it to the fixture load is critical. Check that the breaker, wiring, and voltage are correct, then reduce flow if the water is still lukewarm.

What does the self-diagnostics feature do on the state water heaters UPVS-110Y-100 Electric Tankless Water Heater?

The onboard self-diagnostics system monitors performance and helps protect the unit during operation. It can make troubleshooting easier by helping identify abnormal conditions before they become bigger problems. The bright LED display also provides status updates and lets you adjust system settings. For users, this means faster problem detection, simpler maintenance checks, and better confidence that the electric tankless water heater is operating as intended.

Can the state water heaters UPVS-110Y-100 Electric Tankless Water Heater help reduce energy bills?

Yes, it can save energy because it heats water only when needed instead of maintaining a storage tank full of hot water all day. That on-demand design can reduce standby heat loss and may lower utility costs in the right application. The efficiency rating is 0.91 UEF or higher, which supports its energy-saving design. To get the best results, use it for the correct load and avoid oversizing the installation.

How do I fix scale buildup in the state water heaters UPVS-110Y-100 Electric Tankless Water Heater?

Scale buildup can reduce heating performance and shorten service life, especially in areas with hard water. This model includes scale detection and is designed for easier maintenance, but it still benefits from regular inspection and cleaning. If you notice reduced flow, longer heat-up times, or error alerts, check the inlet screen and flush the system as recommended in the manual. A water treatment solution may also help in hard-water locations.

Is the state water heaters UPVS-110Y-100 Electric Tankless Water Heater suitable for emergency eye wash or lavatory use?

Yes, this model is built with a thermostatic design that regulates hot water output and allows easy selection between Lavatory and Emergency Eye Wash modes. That makes it useful for applications where stable outlet temperature matters. For safety-critical uses, it should be installed and configured exactly according to the manufacturer instructions. Always verify that the supply size and temperature settings match the fixture requirements before placing it into service.

How often should I maintain the state water heaters UPVS-110Y-100 Electric Tankless Water Heater?

Routine maintenance should be performed regularly, especially if the heater is used in a high-mineral-water area. Check the unit for scale, verify that the LED display shows normal status, and inspect the water connections and electrical setup for signs of wear. The dry-fire protection helps prevent early element failure, but it does not replace maintenance. Following the user manual and scheduling periodic service can extend the life of the heater.
