Geospring Hybrid Electric Water Heater Operating Modes

eHeat Mode (most energy efficient mode): The heat pump removes heat from the surrounding air, heats the water and moves the cooler air back into the room. Time required to heat water is longer in this mode, but should be adequate for normal demand households.

Hybrid Mode (default mode): Combines the energy efficiency of eHeat (heat pump) with the recovery speed and power of standard electric elements. The control automatically uses efficient eHeat unless the majority of hot water is consumed.

High Demand / Boost Mode: This mode is only necessary if a household has higher than average water usage or the unit is undersized for the household water demands. Perfect for when the homeowner has house guests. In this mode, the unit will use the electric heating elements only when the water demand is higher than normal. When using the heating elements, the water temperature will recover at a faster rate than eHeat or Hybrid modes, but it will take more energy to heat it. Unlike Standard Electric Mode, High Demand mode will only use the heating elements when needed.

Electric / Standard Mode: Uses only the upper and lower heating resistance elements to heat the water. Time required to heat the water is faster than all other modes but it is the LEAST energy-efficient mode.

Vacation Mode: Can be used when you are away from home for an extended period (1 to 199 days) and hot water is not needed. In this mode, the temperature set point will drop the water temperature down to 50°F and will use the most efficient heating mode to conserve energy while the heater is sitting idle. The unit will automatically resume heating one day before the programmed return, so that hot water will be available.
