The 4-litre heater is equipped with a pure titanium water storage tank, which ensures that there is no ‘after taste’. What’s more, high-vacuum insulation around the tank maintains the temperature at the correct level (above 100˚C), guaranteeing negligible standby loss.
Optimal boiling water flow can be reached with 2 - 3 bar mains water pressure connected to the system, but at least a minimum of 1 bar is required with a maximum of 5 bar. Compact in size, the heater fits comfortably into your undersink cupboard. The 4-litre heater (also the 8-litre combi heater) can be installed in combination with our 3-in-1 boiling water tap.
The 4-litre is suitable for a family home but larger households may prefer the 8-litre version with twice as much boiling water capacity.
