Problem
Traditional hot water (ACS) systems rely on large storage tanks that accumulate water, requiring frequent maintenance, purging, and posing a Legionella contamination risk. These bulky installations also consume excess energy and occupy valuable space, especially in large facilities such as hotels, hospitals, and residential complexes.
Solution
Hydronik offers the IHI semi‑instantaneous ACS system, which generates hot water on demand using a 90 m stainless‑steel coil that keeps only 27 L of water in contact with the consumable stream. By eliminating water storage, the system removes the conditions that enable Legionella growth and reduces primary energy consumption by up to 34 %. Its compact design—2.5 × smaller than conventional tanks—fits through standard 80 cm doors and requires no crane or major civil works. The technology is compatible with any heat source (aerothermal, boiler, solar thermal, biomass, etc.), allowing seamless integration into existing or hybrid installations. Maintenance needs are minimal, with recommended flushing only every six months and a 12‑year warranty, delivering long‑term operational savings and a smaller carbon footprint.
Target Audience
Primary customers are engineering firms, installation contractors, and facility managers of hotels, hospitals, senior residences, sports complexes, and high‑density residential buildings that require reliable, space‑efficient hot‑water solutions.
