Hyco PF100LS Powerflow Smart 100L Unvented Multipoint Water Heater 3.0kW with Anti-Legionella Mode

Product Description

The Hyco PF100LS Powerflow Smart 100L Unvented Multipoint Water Heater is an energy-efficient hot water solution designed to provide reliable mains pressure hot water to multiple outlets. Featuring a generous 100-litre capacity and powerful 3.0kW heating element, it is particularly suited to installations where larger volumes of stored hot water are required.

Ideal for kitchens, schools, restaurants, washrooms, healthcare environments, offices and other commercial, light industrial and light domestic applications, the PF100LS combines intelligent energy management with a practical slimline, wall-mounted design.

Hyco's patented technology helps prevent incoming cold water from immediately mixing with the stored hot water, helping to maximise the amount of usable hot water available from the tank. The heater offers Standard, Smart and Eco operating modes, allowing operation to be adapted to different hot water requirements. Eco mode operates at 50°C for efficient everyday use.

For enhanced stored water hygiene, the PF100LS incorporates an anti-legionella mode. When enabled, the heater automatically raises the internal water temperature to 65°C and maintains this temperature for one hour every two weeks.
