The aroSTOR 200ltr heat pump uses thermal energy to heat hot water from an external air duct or from the room it is installed in – using only minimal electricity. It is highly efficient and sustainable, boasting up to 60° in the cylinder without requiring a back-up heater. The pump operates using R290 natural refrigerant, and has two models available with flexible siting.
