Salamander Home Boost
The Shower Power Booster and the Salamander Home Boost, both recognise when pressure and flow needs boosting and boosts the pressure of the incoming mains water. Both can legally be fitted on an incoming service pipe.
The SPB achieves this without complex and expensive electronics, and with a fraction of the power usage of the Salamander, and its cheaper. If its just a single shower or tap you wish to boost then a SP21S on the incoming main is all that is required.
A good shower needs enough water to wash away the suds and enough pressure to give a nice forceful spray pattern. We aim to give 6 litres a minute and a minimum of 3 metres head to achieve this and the SPB achieves this with aplomb
Flow Pressure Output From A Shower Power Booster
For making sure an electric shower works well (typically 4.5 litres a minute), a Shower Power Booster is perfect.
For a Combination Boiler you need to consider if you want to boost more water than for just a single shower or tap used at one time.
Output From Combination Boilers
24 KW Combi Boiler gives 11.5 litres a minute (2 showers)
30 KW Combi Boiler gives 14.5 litres a minute (2.4 showers)
42 KW Combi Boiler gives 20.0 litres a minute (3 showers)
If you have a Combination Boiler which is dropping out due to low pressure and you only want to run one shower or tap then the SPB is for you. If you want up to 12 litres a minute this is the legal limit for a pump on a cold water mains feed and might be provided by other pumps such as the Salamander Home Boost.
The legal limit is there for a reason and if you have several consumers pumping 12 litres a minute from the same service pipe then you will exceed the maximum and cause negative head in the service pipe thus possibly pulling in contaminants. On a shared service on neighbour may ‘steal’ all the water which might be why you are now suffering?
At Shower Power Booster we come across customers who have fitted bigger pumps but the service pipe will simply not deliver 12 litres a minute so its well worth checking the ‘Maximum Free Discharge’ from the service pipe before you fit the bigger pump.
Run a full bore tap from the service pipe or cut the pipe to check if with a unrestricted flow you can physically get 12 litres a minute from the pipe then a pump that pumps up to 12 litres a minute is fine. If you cannot and there is not 12 litres a minute to boost then think again and settle for up to 6 litres a minute?.
Away from a combination boiler on the hot feed you can protect and boost showers or taps in your home up to the maximum capacity of your combi boiler. When others open taps in your home, provided you do not exceed the output of your boiler, the shower which is fed from a pipe with a Shower Power Booster fitted will be protected and will continue to flow strong and good.
