Dehumidifier - Energy Factor and EER Rating
Dehumidifiers do have energy ratings. Many dehumidifiers are Energy Star certified. An Energy Star certified dehumidifier gives you the same great performance as a non-Energy Star model while using less energy and reducing utility costs. We are often asked about how dehumidifiers are rated for energy usage. We are glad to explain.
Ratings
EER (Energy Efficiency Ratio)
EER is a measurement of how efficiently a cooling system will operate when the outdoor temperature is at a specific level. The higher the EER, the more efficient the system. It is calculated by dividing the cooling capacity in BTUs per hour (BTUH) by the power input in watts. EER is expressed as BTUH/watts.
Dehumidifiers are not a cooling system like an air conditioner is a cooling system. EER is determined by dividing BTUs by watts. Dehumidifiers are not rated for BTUs, so there is no EER rating on a dehumidifier.
EF (Energy Factor) or IEF (Integrated Energy Factor)
Energy Star tests and rates the efficiency (Energy Factor) for dehumidifiers. Energy Star is governed by the U.S. DOE (Department of Energy) and EPA (Environmental Protection Agency). The Energy Factor is expressed as IEF. The higher the IEF rating, the more efficient the dehumidifier is. The IEF is listed in L/kWh (liters per kilowatt hours).
