Riello. RBC-HP 1S. A multifunctional series designed to produce domestic hot water via a heat pump or a boiler. The tanks are vertical, have a single coil and are fully enamelled to guarantee high hygiene standards and prevent limescale build-up. The range consists of 6 models, from 150 to 1000 litres. Thanks to the shape of the coil and the tank, it is possible to achieve very high heat exchange performance (with low pressure losses) and fast recovery times. A removable coil (optional) can be fitted to combine with a solar system. It is also possible to fit optional electric heating as a backup. ErP Ready.
