I want to Boost The Flow From a Combination Boiler

A Shower Power Booster is the only pump you can fit on the hot side of a combination boiler. A SPB cannot be hurt by the boiler, a SPB cannot hurt the boiler.

If a shower or tap is a long way from a combination boiler or the pressure fluctuates when you open another tap in your home, you can fit a shower power booster on the hot side of a combination boiler to protect and boost the flow to that shower or tap. A single boost SP1 or SP2B is all you need.
