* Sound Power Level measures the sound energy emitted by a source. Sound Pressure Level (SPL) measures the sound level (loudness) at a distance from the source. SPL varies depending on the acoustic environment and the accuracy of the measurement device.

Heat Pump Comparison and Mode

"Hybrid" Water Heaters		Accelera Heat Pump Water Heaters
Their most efficient mode provides the greatest savings they're capable of. Water heaters operates only with the heat pump. "Hybrids" must be set to the correct mode in order to either save energy or provide comfort.	Heat Pump Mode	This is the main setting. Accelera is engineered to satisfy 90% of hot water needs through the use of the heat pump alone. In cases of high demand, one specially-designed electric "booster" element is located at the very top of the tank. Positioned near the hot water draw point, the element has been designed and engineered to run as little as possible so that comfort is maintained and savings maximized.
Two standard electric elements activate for fast water temperature recovery. System allows heat pump to work once demand has been met via electric elements.	Hybrid Mode	Accelera is designed to satisfy hot water needs without having to pick a setting. There is nothing to remember to choose i order to have both comfort and savings.
Twi standard electric elements activate sooner and stay on longer than in their "hybrid" mode.	High Demand Mode	Accelera is engineered to work as a harmonious whole to offer comfort and savings without having to ask, "what setting do I need to choose today?" In cases of extraordinarily high demand the Accelera 220 E has a user accessible booster function that will engage the booster element.
Heat pump is disabled and, just like a standard electric tank, two electric elements heat the water. "Hybrids" don't have active defrost and must enable this mode so the evaporator can defrost. This mode is also selected if the heat pump fails.	Standard Mode	Accelera was engineered so that the heat pump doesn't need to be disabled for a defrost cycle. We also engineered for reliability. Why pay extra for a heat pump water heater if you're just going to end up with a standard electric tank?
Water heater maintains a very low temperature in the tank then reheats the water the day before you return.	Vacation Mode	Our super-insulated tank keeps water hot in an Accelera during a 2-week vacation for less than $4. No one has t worry if vacation mode was set to wake up on the correct day.
