Every Tempra® also has self-modulation. Self-modulation is sometimes confused with flow control, but it has more to do with the amount of energy used to heat the water. Self-modulation, sometimes call auto-modulation, ensures that only the least amount of energy is used at all times. Every Tempra® model continually monitors incoming water temperature, the flow rate of water through the heater, and the water temperature it produces. These sensors feed their readings into the unit’s proprietary microprocessor control which engages the heating elements in stages, as efficiently as possible, to achieve the water temperature set on the front panel, always using the least amount of energy necessary to heat the water.
A Stiebel Eltron Tempra® responds directly to your demand for hot water without interruption. Showers will always be hot, even if there are several taken in a row and they run long. A tank water heater may be able to deliver more water all at once, but once the tank starts to deplete things get cold and pretty quickly come to a standstill while waiting for the tank to recover.
The correct size Tempra® largely depends on the temperature of the ground water and the number of bathrooms in a house. It’s easy to determine which Tempra® model best satisfies a household’s needs. Click the map for the complete Sizing Guide.
If there are high flow showers, or another out-of-the-ordinary situation, please call or email for advice. Stiebel Eltron service representatives provide assistance and make recommendations on sizing, or any other matter concerning our water heaters, to both homeowners and professional installers.
Compared to a conventional electric tank water heater, a tankless electric water heater will typically use 15–20% less energy, although savings can be substantially higher depending on usage habits. Conventional electric tank water heaters continually store hot water and as a result lose 15-20% of the total energy they consume to the environment around them. This is called standby heat loss. Gas or oil tank water heaters are even less efficient due to the fact that they also must be vented to the outdoors. A tankless electric water heater does not need to be vented, and does not store full temperature hot water waiting for you to use it.
In addition, installing low-flow showerheads and flow-reducing sink aerators, coupled with optimising your personal water usage habits can result in savings much greater than the typical 15-20%. Installing additional point-of-use tankless water heaters at individual sinks or other hot water usage locations can provide additional energy savings.
