Potable HWS using heat pump technology

UK: HVAC equipment supplier Exi-tite has developed a self-contained potable hot water system using heat pump technology.

The packaged system can be installed as a permanent fixture or mobile plug-in solution across various applications. Heating capacities ranging between 13kW and 240kW and low-GWP refrigerant options are offered.

Prefabricated off-site, the system is designed to save time and avoid logistical complications. It is constructed on a structural framework and designed to be wheeled or crane lifted into position.

LG VRF heat pumps provide modular capacity control and redundancy, and are inverter-driven with both latent and sensible load monitoring. Each Multi V i system is connected to a high-temperature hydro kit, capable of producing water temperatures up to 80°C and providing 100% heating capacity down to -7°C.

The company’s first packaged hot water system, designed to provide 100kW capacity split into four 25kW stages, has recently been delivered to a project in Leeds. The 1650-litre energy bank supplied can provide 1800 l/hr of usable potable water, raising from a mains cold supply to 60°C with a 7 minute recovery time of the energy bank.

The method of hot water generation differs from typical systems that store potable water. Because the packaged Exi-tite system heats cold mains water directly through a heat exchanger without storage, pasteurisation is unnecessary and the need for salt-based softeners is also eliminated.

The system is plug-and-play, arriving with its own localised control, but is also pre-wired for connection to a building management system and pre-piped with connections to the cold water main, hot water supply and optional circulation loop.
