Heating Performance and Technical Information
Each SNU Plus + WST‑W set combines a compact non‑pressurised small water heater with a matching WST‑W low‑pressure washbasin tap engineered for use with vented systems. This configuration delivers hot water directly at the sink with minimal lag between turning on the tap and hot water delivery, eliminating lengthy pipe heat losses.
The 5 litre model is ideal for single washbasin applications and lighter usage, providing sufficient stored hot water for frequent short draws and efficient reheating. The 10 litre version increases stored capacity, offering more hot water per draw while still maintaining compact dimensions suitable for typical undersink spaces.
Both heater options operate on a 230 V single phase supply with a 2 kW connected load, delivering consistent performance with energy efficiency class A and low standby energy consumption.
The included WST‑W vented mixer tap is designed specifically for use with the non‑pressurised SNU Plus heater, ensuring optimal flow characteristics and compliance with safe operating conditions.
