⚡ At a Glance
- • Hot Water Retention: Thick high-density polyurethane insulation reduces heat loss and keeps water hot for longer
- • Best for: Small kitchens and under-sink installations needing reliable instant hot water
- • Not ideal for: Large households requiring whole-house or high-volume hot water supply
Undersink 10 L electric heater with a 2 kW control unit and B class ErP rating. Titanium enamelled tank and immersion thermostat support durable, precise temperature control.
Quick access to hot water - thanks to a 2 kW control unit
A 2 kW control unit delivers steady heat input to the 10 L tank while an immersion thermostat monitors and maintains the chosen temperature. The thermostat allows precise cut-in and cut-out to avoid wide temperature swings.
Ready-to-use hot water at a single sink or small wash area, suitable for washing up and quick chores. Predictable temperature control reduces the need for repeated reheating.
Lower standby heat loss - with thick high-density polyurethane insulation
High-density polyurethane insulation surrounds the tank and outer casing to limit conductive and radiative heat losses. A thicker insulating layer slows temperature drop when the water is idle.
Less frequent reheating and steadier tap temperatures between uses, helping to keep running energy use lower. Particularly useful in kitchens with intermittent hot-water needs.
Long-lasting tank protection - thanks to a titanium enamelled tank
Titanium enamel plating forms a corrosion-resistant surface on the tank interior, reducing chemical and electrochemical wear. The treatment helps to maintain tank integrity under regular heating cycles.
Reduced risk of corrosion and longer service life compared with untreated tanks, lowering maintenance worries and replacement frequency. A more robust tank supports reliable performance over time.
