A Shower Power Booster is the only pump sold which legally and safely boosts the hot water from an unvented hot water. It can also boost pressure to an unvented tank, calorifier, or Megaflow. If the only problem is your hot water pressure then a SP2B can give a single boost, and a SP21S a double boost (.8 bars), to benefit every hot tap and shower fed from the hot water cylinder.
You can combine a ‘Whole House Pressure Boost’, with a ‘Boost and Protect The Flow To a Single Tap or Shower’.

We recommend the SP21S
The SP21S is a two pump set. Fit both pumps before the unvented cylinder, after the unvented cylinder or either side of the hot tank.

Protected Flow Hot Water Solution
We recommend the SP2B
You can boost and protect the hot only pressure to a single tap or shower if you can fit the pump to the pipe that feeds just that tap or shower. A single boost SP2B on the hot should be good enough for a single shower or tap but a double boost is better if you have enough space to fit it.

We recommend the SP21S
Whilst it is better to target individual elements of you plumbing it is possible to boost all of the mains water. The SP21S is a two pump set to double pressure boost the mains feed.
