RESIDENCE HM AQUA is the condensing boiler with 30 litre stainless steel bi-tank storage tank, designed by Riello in the name of energy saving and efficiency.

RESIDENCE HM AQUA consists of a system composed of a combined 25 or 35kW 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, entirely made of stainless steel, together with the optimised plate heat exchanger, for instantaneous DHW production when the storage tank is not needed, ensure maximum efficiency, reliability over time and high comfort. Compact dimensions and an intuitive user interface complete the RESIDENCE HM AQUA profile.
