Identify the Tempra model and demand pattern
Stiebel Eltron’s Tempra family is electric tankless equipment. Tempra Plus models list Advanced Flow Control, while the brand also publishes other configurations. The model designation helps distinguish the controls and requirements of the installed system.
If the flow changes when several fixtures operate, describe that behavior along with the temperature. Reduced flow and complete loss of heating are different symptoms. The service discussion should include simultaneous demand rather than rely on the appliance name alone.
Before choosing a replacement
Before a larger electric tankless replacement is proposed, assess service capacity and the required circuits. Compare output using incoming water temperature and your busiest fixture combination. Ask how a selected model handles demand beyond its available heating capacity.
Plan service around your home.
For a Marietta home with the heater in a basement, garage or utility closet, tell the team about the location and any restricted access. Mention stairs or a narrow removal route when discussing replacement. The installation area can affect the work as well as the choice of equipment.
Compare output at the required temperature rise, simultaneous fixture use and available utility capacity. On-demand heating does not guarantee unlimited flow or immediate hot water at a distant faucet. Learn about repair, replacement and maintenance before you call.
Describe what you can see safely. Leave gas, electrical, venting and pressure-relief work to qualified professionals.
