We can supply one of two pressure relief valves free of charge. Please indicate, which one you prefer by ticking the box at 'Available options' when ordering. The valve with the red lever has a small orifice. You can connect the supplied discharge pipe that orifice to drain of drops of expansion water. The other valve is a WRAS approved pressure relief valve. This WRAS approved valve can only be used together with a WRAS approved check valve and a WRAS approved expansion vessel.

Install the ordered 6 bar pressure relief valve or a 6 bar WRAS or KIWA approved pressure relief valve for the water heater to function properly and to retain your guarantee. 

Using the wrong bar pressure relief valve can cause leakage inside the boiler as the working pressure inside the tank will exceed the maximum tank working pressure of 6 bar. It can also cause excessive calcification inside the tank. Calcification on the heating element slows heat transfer and will cause the heating element to overheat. Overheating weakens the steel and will eventually cause the steel to tear resulting in a short circuit.  

We strongly recommend to install a pressure reducing valve if the water pressure is too high (5 bar or more) or if you suffer from fluctuating water pressure. High water pressure and/or fluctuating water pressure often occur in apartment building, flats, farms, older houses and houses and buildings in elevated areas. Install a pressure reducing valve where your mains water supply line enters your premises or right behind the pressure relief valve. Ensure the water pressure is set at 3 bar. Any damage caused by a too high water pressure or fluctuating water pressure will not be covered by the warrantee.


I received my order yesterday. It took only 2 days to arrive from the Netherlands. Good job!
