Factory Refurbished Tempra 12
This is a factory-reconditioned unit with 1 year manufacturer's warranty. Reconditioning and re-testing was performed by the manufacturer to its exacting specifications. There may be minor cosmetic blemishes (small scratches or scuffs) on the unit. We 100% guarantee that this unit will operate according to the manufacturer's specifications. This is an excellent opportunity to buy a brand name water heater at a significant discount to the cost of a new unit.
The Factory Refurbished Stiebel Eltron Tempra 12 electric tankless water heater is mostly used for single point of use applications in Canada as it is designed for lower flow rates. With 12 KW of heating power it provides endless hot water at low flow rates even in our Northern climate.
The Tempra 12 features Stiebel Eltrons true microprocessor-controlled temperature regulation and full power modulation based on both incoming water temperature and flow rate required. This means the Tempra 12 will measure the flow rate of whatever applications you have turned on, determine the incoming water temperature, and apply the appropriate amount of power to heat the water to the temperature you have set it to. A dial on the front of the unit allows you to set the output water temperature anywhere between 30°C and 60°C. The Tempra series of electric tankless water heaters are one of only a few tankless water heaters available today that feature a true thermostatic temperature and full power-modulation experience. This means no fluctuating water temperatures.
The Stiebel Eltron Tempra Series electric tankless water heaters feature the most precise temperature control of any tankless water heater on the market today!

* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.
