    As with any hot water or heating appliance, a hot water boiler system requires a constant pressure flow to maintain the optimum temperature. Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops. Despite the pressure reducing valve, owners should be familiar with the standard PSI of their hot water boiler system …Learn More

  • How to increase water pressure in a shower with a combi boiler

    Ideally, the combi boiler flow rate for a good shower should be at least 12 - 15 litres a minute. The flow rate simply refers to how much water can pass through the appliance to feed taps and showers once the boiler is working. Choosing a powerful combi boiler with a good flow rate will help you to optimise hot water pressure around your home.Learn More

    Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.Learn More
