Can TankBoost water booster be used on combi boilers and unvented systems?

Yes, TankBoost is ideal for delivering pressure and the higher flow rates required to unvented systems up to 80 litres per minute. TankBoost can also be used to supply combi-boilers, however, combi-boilers may restrict the flow rate of hot water that can be produced.

Can you use TankBoost to pump hot water?

No, TankBoost has been designed for cold water only, it can however be used to increase cold water flow rates and pressure to any mains hot water system such as unvented cylinders and combi boilers.

What pipework connections does the TankBoost have?

All TankBoost units have a ½” brass male inlet connection and 1” female outlet. It is recommended to have 28mm diameter pipework from the TankBoost so as not to restrict the potential flow rates from the unit. This can then be reduced to 22mm or 15mm pipework closer to the outlets.
