What might make combi produce low dhw flow?

[WaterTight]

Mum just moved into new place. I am not GSR but can do rest plumbing. She has a logic 24 combi. Hot at all outlets flow resembles what you might get from a fortic in a flat. Boiler fires fine, water gets hot, just poor flow. Cold is fine/normal. Is this something a gas safe guy will have to investigate/fix or something I can look at?

Thanks

24 kw is about 9 litres a min.
Might look poor through a bath tap. Measure flow into a jug and time it. That will give you litres a minute. Bet it's not far off.

It's the lowest flow I've ever seen on a combi and have worked on taps on hundreds of combis. I would guess from checking it out it would be maybe 4 litres a min tops.

Yep dont expect much out of a 24 KW

Bloody hell lol

tbh she's not fussed but doesn't seem right to me and if it was a reasonably simple fix, even if needing a gas safe chap I'd recommend it for her. Just want an idea.

dont know if they have but check the strainer

Is your mum in a hard water area?

Are flow restrictors fitted?
Could be the strainer partially blocked?

 

[WaterTight]

As said, not GSR so no knowledge about boiler parts/workings.

Would the strainer be this thing on the right? And how do I 'check' it?

It is a hard water area yeah. Not sure if flow restrictors are fitted or where I would check that, unless you mean at/on the taps?
