Methods to boost incoming water supply

[sturharv]

Of the two main methods used to improve the water pressure into a house (break tank / booster set and an accumulator expansion vessel), which of the two do you consider the better i.e. on reliability, performance etc. I am working on a large property with around 4-5 bathrooms and shower rooms and the water pressure is only 3 Bar static and 1.9 Bar dynamic pressure.

Any experts on this out there please??

If you take 3 showers together, you'd need enormous accumulators.
What size is the incoming mains pipe? If it were 32mm mdpe you probably wouldn't need to boost the pressure.

the water pressure is only 3 Bar static and 1.9 Bar dynamic pressure.

Static pressure is fine, but your figure for dynamic pressure means s0d all without stating the flow rate at which it was measured, e.g. 20 litres/min or whatever. As ChrisR suggests, best option is usually to look for principal source of dynamic pressure loss (usually supply pipe from main) and consider upgrading that.
