    Hi
    Boiler was running great until we had it serviced but immediately after engineer left, we noticed the hot water flow was a lot slower from all the hot taps. Does anyone know why this is?
    Regards

    Probsbly the water inlet valve not fully open. Call the engineer back and tell him to fix it. It’s his fault

    Thanks for your reply jonathanc.

    Called back, got a different engineer. He replaced the flow adaptor. Now we have the flow problem with no hot water, cold out of both taps.

    Repeat the process in post 2. Don't let the engineer leave until you are happy with the work, do not pay for any more time or parts. With my Worcester boiler I use the adage' If it ain't bust, don't fix it'.

    Yep, regretting that service now!!! Already paid, contract with BG. Had another visit but still none the wiser, calling back Monday to replace/remove combisaver

    Sounds like the engineer is an idiot

    the combi saver is pointless. It works on the basis that the boiler is heating water from cold so you run the tap until it gets hot enough. Your boiler probsbly has a small heat store so it’s instant hot.

    Never understood the need for combisave ! It’s nothing more than a thermostatic restricter that reduces flow till the water warms up and gradually increases the flow as the water warms up.

    You can do that by just opening a tap enough to start up the boiler.

    these need the minimum flow to be adjusted so the boiler starts up and carries on running as well as the temperature setting. To get the maximum energy saving, the minimum flow must be just enough to trigger the boiler but not excessively so. A drop in external water pressure feeding into the boiler can mean it stops functioning. Result no hot water.

    in my view another so called energy saving product that under controlled conditions may save a bit of energy but far more trouble than it’s worth.

    Much like the electricity saver devices that drop the voltage by about 10v. Works on things like lights as the dimming is not so noticeable but appliances that need to heat simply take longer and net energy usage remains the same.

    Story so far

    Boiler working fine.After service,heating and hot water temperature all ok but hot water flow a lot slower

    Everything apart from the hot water flow working fine 2 weeks later when different engineer arrives to sort hot water flow problem

    He said he had never come across this before and didn't know the cause. He isolated hot water and turn on cold tap and it was back filling through boiler and managed to flood a cupboard in the process. He said he suspected mixer taps blending (after phoning a colleague) and would put everything back to how it was as it was a plumbing issue.

    Later that evening, the hot water tap started to run cold. Tried every hot water tap in the house and all running cold. Heating was not on but the radiators started to warm up, checked the boiler and it was definitely set to off. Turned the wall thermostat down and the radiators cooled down.
    So now no hot water whatsoever even though the boiler is firing up when the hot water tap is turned on

    Dynarod came following day (Wed)and said that a faulty mixer tap would not affect the flow of the water

    BG engineer came (same one) Thursday. After all of the above, still no idea what the problem is. Said all he could do was take the combisave out but needed to order the part. Will be back on Monday.

    So we have gone from no issues whatsoever to a slow hot water flow issue to no hot water flow issue.

    Can anyone shed any light as to what the real issue might now be so I can get some hot water...please
