Point-of-Use Water Heaters
We are happy to be able to offer a full range of point-of-use tankless and mini-tank water heaters to suit almost every point-of-use water heating application.
Applications include bathroom sinks, kitchen sinks, utility sinks, dishwashers, staff lunch rooms, emergency eyewash stations, pre-heaters for small dishwashers, restaurants, fast food outlets, cafeterias, hand and hair washing sinks in spas and beauty salons, and any other small domestic hot water heating task.
A wide variety of models are available, in both tankless (on demand / instantaneous) and mini-tank designs:
 |
Stiebel Eltron Mini Series Tankless Water Heaters
Economical model designed for low-flow point of use applications in warm climates. The Mini Series Tankless are most suited to applications where the flow rate does not fluctuate as they are not thermostatically controlled. Their ultra-compact design saves space and allows them to be installed in very confied areas right next to the application. |
 |
Stiebel Eltron Mini-Tank Series Water Heaters
Very economical. Excellent choice where only 110/120v power is available and water is used infrequently. Space saving design - conveniently mounts under a sink or in a nearby cupboard. Available in 2.5 and 4 gallon tank storage capacities. These Mini-Tank Water heaters work best where only small amounts of hot water are needed at a time. Due to their small dimensions, the SHC Series easily fit under a sink or in an adjacent cupboard or closet, so they provide hot water to the point of use almost instantly |
 |
Stiebel Eltron DHC Series Tankless Water Heaters
Economically-priced point-of-use tankless water heaters with up to 10KW of power are suitable for almost all point of use water heating applications. 110/120 volt and 208/240 volt models available. Best suited to single applications with a relatively consistent water flow rate and pressure as they are not thermostatically controlled. The DHC Series are extremely energy efficient, as they produces hot water on demand only as it is being called for. |
 |
Stiebel Eltron DHC-E Series Tankless Water Heaters
Fully thermostatically-controlled tankless water heater with true flow-based power modulation. Available in power ranges up to 10 KW (208/240 volt configuration). The DHC-E series are an excellent choice for point-of-use applications where flow rates or water pressure may vary or where very low activation flow rates are required. These units feature a digital temperature selector. The Stiebel Eltron DHC-E series tankless water heaters are the most technologically advanced point-of-use tankless water heaters available today. |
Point of Use Tankless Water Heater Selection Guide
The three most important important considerations when choosing a point-of-use tankless water heater are:
- Water Flow Rate
- Incoming Water temperature
- Activation Flow Rate
The following chart will provide you with some guidelines as to the flow rates of common water applications. It is important to note that these flow rates are only estimates and can vary based on water pressure, the faucet installed, and a variety of other factors. Accordingly, you are encouraged to test the actual flow rate of your application for a more precise model determination.
Application |
Flow Rate in GPM at 60 PSI |
| Bathroom Sink Faucet |
0.5 to 1.5 GPM |
| Average Kitchen Faucet |
1.0 to 2.2 GPM |
| Average Shower |
1.5 to 2.0 GPM (Max. 2.5 GPM) |
| Average Bath Tub |
2.0 to 3.0 GPM |
| Washing Machine |
1.5 to 3.0 GPM |
Once you have determined the flow rate your require, use the map and chart below to determine which models are able to meet your flow rate needs based on your incoming water temperature. It is important to verify that the activation flow rate for the model selected is less than the flow rate of your application or the heater will not activate.
