No pressure from hot taps

[pearlscafe]

Can't get decent pressure from any of the hot taps.

Combi boiler has had heat exchanger renewed as scaled up but still not getting pressure from the hot taps.

Guessing some limescale may have got dislodged but not sure best way to flush out.

Any suggestions please?

Yuo need to measure static & dynamic water pressure and record the flow rate from the taps in Litres/min, compare this to your Cold taps, then re-post with this infomation.

You do not say the make & model boiler, but i have known instances where the domestic water manifolds (the brass blocks that the plate HE bolts to) being scaled up and causing a restriction too !

Thanks for reply, got a heating engineer to sort it in the end. Had to replace a section of pipe under the floor that was clogged with limescale.
