Can you put a booster pump on a hot water supply? Tenant is complaining of low hot water pressure filling the bath, after the boiler but before the bath

You would have to know more about the hot water system fitted (stored or combi) but both Tom and Plumber Boy had good threads on just such jobs with very competitively priced equipment.

It’s a combi mate a baxi, kitchen sink which is by the boiler has good flow but upstairs bath is ridiculously slow |

The combi is only going to give a certain amount of litres of hot per min. The bath will probably be on 22mm pipe so comparing it with the kitchen sink on 15mm is not reasonable.
I think it is what it is. You can’t boost the hot after the boiler as the boiler itself can’t give enough.
It is what it is.

I would say, you're stuck with what you've got, adding a pump will cause more trouble, better to look at upgrading the mains water, attack the source of the problem not the symptoms , I know thats going to cost and be messy but at the end of the day, Its the only rel fix,  |

Its the mains thats pushing the hot water out, a combi will produce 13 litres a minute of hot water but, only if the mains can supply 13 litre per minute, from what wingnut says, thats not happening  |

I ask as my bath fills slower than her indoors would like bit my mains pressure is good. Any ideas & I’ll text it. I’ll look at WB mi’s too |

My WB boiler is min 1.3 bar mains pressure for optimum performance, it’s not much. I was expecting 3bar +.

the water board has recently lowered the pressure all over the country because of leaks but, you would expect 3 bar incoming mains, The water board are only expected to deliver 9 litres per minute at 1 bar, So if your pressure is 1 bar and 9 litres, the water board will do nothing, if its less they will
