This super-powerful, electric water heater can replace traditional tank storage heaters.

The Eccotemp ET-32 is used in high-output applications where the hot water demand is more than what the ET-14 or ET-22 can provide. This high-end residential electric tankless heater can provide hot
water to the whole house. The ET-32 is also ideal for light commercial applications such as offices, convenience stores, restaurants, salons and pet grooming shops. It can function as a powerful replacement or booster for traditional water heaters. The temperature controller works well in recirculating systems or with tank heaters for specialized applications like body spas or roman tub fillers.

How to adjust the output temperature

On the left side of the control board is a temperature adjusting knob. The factory setting is usually between 118°F and 122°F. The knob will usually be in the 2 to 3 o'clock position. To decrease the temperature, turn the knob to the left. To increase the temp, turn it to the right.

• A higher temperature setting could cause the water heater to use more power, reducing energy savings.
• A higher temperature setting may increase the amount of scaling and sediment on the heating elements.
• Your output water temperature may not reach your temperature setting if the flow rate too high or incoming water temperature is too low. Check the temperature rise table.
