Do I need a pump?
To determine if you need a pump you need to establish:
1. What kind of water system you have.
This is important as booster pumps can only be added to gravity systems. You must NOT fit booster pumps to high pressure or combination boiler water systems. If you are unsure, about your water system you can ask your plumber or check out our Water System Compatibility tool.
2. Whether you have sufficient vertical distance from the bottom of the cistern to the top of the shower head.
This is because the greater the vertical distance (called "head of water") the better the shower’s flow rate and performance. Typically this should be no less than one metre. Aqualisa Thermo products are specially designed to work well under gravity conditions. See our video on How Thermo works.
However gravity systems can sometimes have a disappointing flow of water if there is not a good “head” of water. Adding a pump can make an enormous difference to your showering experience and will allow you to add extras such as body jets.
Handy hints
It’s essential that you choose the right pump. Not just for you, your family and your new shower – but for the plumbing system too. A pump will increase the volume of water your shower can deliver per minute and it’s important to check your water tank will have enough storage capacity to cope. Vital during the morning rush hour when everyone wants a hot shower.
Don’t overlook where all that extra water will go to either. You’ll need to ensure your shower tray’s waste is sufficiently capable of quickly and effectively draining water away.

Alternatively you can purchase a shower that has a pump already included. See the pumped products in our Digital range or the Aquastream Thermo.
