In the common hydronic heating systems in the states the supply to the
furnace has an inline pressure regulator to protect the closed heating
system. The furnace will also have an over pressure blow off regulator
on it and in older system an expansion tank.Hot water for faucets and
showers is a separate supply running at house pressure ~ 70PSI or 4.8
BAR.
If you're drawing hot water off behind the regulator for a shower I can
see how the pressure would be greatly reduced.
The regulators I deal with look like the ones on this page:

Except they have an over ride lever on the top. When we refill a system
we over ride the inlet pressure regulator othewise the system will take
hours to fill.
3 bar would be at the low end of an acceptable home supply. >1 bar
would be miserable!
