Product Description
The Hyco SF15L1SS Speedflow 15L Unvented Water Heater is a compact and energy-efficient solution for providing mains pressure hot water to multiple outlets. Equipped with a 15-litre stainless steel tank and 1.2kW heating element, this lower-load model is particularly suitable for installations where electrical capacity is limited.
Ideal for kitchens and cloakrooms in offices, shops, student accommodation, domestic extensions and similar environments, a single Speedflow Stainless heater can supply hot water to up to three basins. Its compact design allows discreet installation within an under-sink kitchen cupboard, making it an excellent choice where available space is restricted.
The SF15L1SS combines an ErP A energy efficiency rating with external temperature adjustment and frost protection for convenient everyday operation. Its durable stainless steel water tank provides dependable performance, while mains pressure operation means the heater can be used with standard taps, including mixer taps.
