Residence Aqua is the condensing boiler with 30-liter stainless steel bi-tank designed by Riello with energy saving and efficiency in mind.

Residence Aqua consists of a system composed of a 25 kW combi-boiler and a compact bi-tank that is distinguished by the simplicity of installation in just two steps: installation of the storage tank on the wall and the boiler on it.

The primary heat exchanger, made entirely of stainless steel and with front accessibility to the combustion chamber, together with the optimized plate heat exchanger for instantaneous DHW production during periods when the storage tank is not needed, ensure maximum efficiency, long-term reliability and high comfort. Compact dimensions and an intuitive user interface complete the profile of Residence Aqua.
