In order to improve the effeciency of small scale water purification and desalination, the device attempts to capture the waste heat from distilation to preheat incoming water. The device centers around an electric pressure cooker which acts as the boiler. A copper condenser coil is submerged into the next batch of water to be distilled, preheating it and thus saving some energy.
