Solcore - K5 (F1D) - Instantaneous Water Heater (inverter)

The Solcore K5 (F1D) is a compact, wall-mounted instantaneous electric water heater with inverter technology that keeps the water temperature stable and uses only the power it needs. Choose 3.5, 4.5 or 5.5 kW to suit your electrical supply, and set the temperature from 25°C to 55°C on the digital LED display with touch controls. A cast aluminium heating element, continuous self-diagnosis and double leakage protection (RCD 28 mA plus earth leakage protection wall) give reliable, safe operation. Measuring just 30.5 × 13 × 7 cm, it can supply several outlets as a main or supplementary heater, and can be connected in series with a solar water heater.
