High pressure & combi boiler suitableThese showers are suitable for high pressure and combination boiler water systems. This means that they’re suitable for combination boiler or mains pressure systems where the supply pressure is in excess of 0.5 bar. Precise temperature controlStandard showers can have hot temperature spikes when others in the house turn on taps or flush the toilet.Thermostatic control means that this shower will hold its temperature steady at all times. It dynamically adjusts the hot and cold water offsetting the everyday changes in water pressure experienced in most family homes.
