How Does It Work?

Double Boost the Whole House

Simply install a SP21S double boost on the cold-water feed to a combination boiler. This will  boost the flow to every tap, bath or shower in the home, but the benefit will be lower if more than one tap or shower is used at any one time.

A double boost before the boiler can stop it shutting down because it increases the pressure but it is only suitable for keeping one shower or tap running at any one time. Great for a small home but not a large house with multiple users..

Single Boost an Individual Shower or Tap

If you have poor performance of an individual outlet, fit a single SP2B on the hot feed or better still a pump on the hot and cold feeds to the particular tap or shower. It will not only boost pressure but maintain it when other taps, toilets or showers are used. Unlike the whole house boost you can protect and boost up to 3 individual taps and showers when you put our pumps on the hot side of the Combi Boiler.

Protecting a Combi Boiler

Combination boilers are fitted with a pressure sensor which turns off the gas supply if cold water pressure falls below 1.0 bar. The Shower Power Booster pumps can be legally fitted to the incoming water supply to protect against this happening and they are fully compliant with UK Water Bylaws

The Shower Power Booster pump is designed to be quiet, energy efficient and provide the optimum boost for most applications. A single pump will provide a 0.2-0.4 bar boost which is all you should need for an electric shower, but we recommend a SP21S double boost upstream of a Combi Boiler to protect a single tap or shower.

The Shower Power Booster pump which does not cut out due to low mains pressure will protect multiple showers if each shower is protected with its own pump on the hot side of the Combi. To read more about boosting taps and showers if you have a combination boiler “click here”

Ask Alan

t

My mains water pressure is poor. Will the pump help?

Yes, the Shower Power Booster can be added to the feed to provide a welcome boost for all hot water. If mains pressure rises it will never impede flow either.

t

How much will the pump cost to run?

The Shower Power Booster gives an optimum boost but consumes just 12 watts. It’s much more efficient than conventional pumps which produce similar results.
