• COMBINATION BOILER SOLUTIONS

Combination boilers are fitting with a pressure sensor and if the pressure of the incoming mains cold water supply drops below 1.0 bar the gas is turned off. The Shower Power Booster can be legally fitted to the incoming mains cold supply to increase the pressure and flow rate to stop this from happening.

In most cases a single pump is enough to keep the boiler active adding between 0.2 and 0.4 Bar of pressure. However, you can add a second pump to give a double boost adding around 0.4 to 0.6 Bar to the pressure preventing the combination boiler from falling below 1 bar.

Although the output of a combination boiler greatly exceeds the output of a Shower Power Booster you can still expect to protect flow rates of 6 litres a minute to showers and around 8.5 litres a minute to taps.
