THIS ELECTRIC TANKLESS WATER HEATER uses a coilless heating element that is not in direct contact with the water being heated. The innovative design prevents the build-up of lime-scale and mineral deposits that can cause a standard model to lose efficiency over time. The unit delivers 95%-96% thermal efficiency over its working life. The heater is maintenance-free and suitable for all water conditions.
