Will the Stiebel Eltron Tempra Electronic Tankless Water Heater work if I have a well and pump?
Sure it will. The unit operates in a range between 5 – 150 psi. Actually, the lower your pressure is, the higher the temperature rise produced by the unit. The optimum range you should set your pump at is 50 – 70 psi. Caution – If the pressure gauge on your pump permits the water pressure to vary by more that 20 psi, the operation of the Stiebel Eltron Tempra Tankless Water Heater can be impaired.
