Product overview
Instant heaters hold only a few litres and heat on demand, so they suit a kitchen sink or washbasin rather than a shower. Because there is no stored tank sitting hot, standing losses are effectively nil — the heater consumes power only while running. The limitation is flow: three litres will not sustain a shower, and attempting one produces a thin lukewarm stream.
Key capabilities
- 3 litre instant heating capacity
- 3000 W heating element
- Rustproof ABS outer body
- Thermal cut-out and pressure relief valve
