Variable flow Water Pump for instant water heater?

[DuckyUC]

Hi again

I fitted a instant electric water heater to supply hot water for whole flat
but the hot water flow are quite low

So I am finding a pump that can:

1. pump only on when water flow
so no pump noise all the time and the pump have longer live

2. pump can tune how much water flow/pressure to increase
the water heater have a max 10bar Rated pressure
If the water flow too high the water heater wont able to heat up the water to require temperature

I find a pump call Salamander home boost on google
It only on when water flow but it design to maintain 12L/min all the time so I do worry that will give too high water flow and the water heater wont able to heat up the water to require temperature.

Any recommend for water pumps?
