    Worcester Bosch Greenstar Boiler - Temperature Cycling

    3 Radiators do not have TRVs and there is a boiler bypass pipe. Also - the pump appears to struggle even with just the HW circuit open, so I'm hoping it's either the pump or a blockage ahead of the 2x 2port valves..

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    The original installer has ceased trading, so will call a local plumber. The system seems to be somewhat cursed as within the 3 years its been installed.. 1 2 port valve has died and needed to be replaced. Both the HW and CH expansion vessels failed. Now it looks like the pump has gone and...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    So.. having gotten home this evening, I've opened up the magnetic filter and it didn't look too bad. Very little build up, but I've given it a clean and put it all back together again. Fired up the boiler and the pump is definitely struggling. I've tried just running the HW circuit, just the CH...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    Actually - my description above isn't quite right. Here's a plan of the system. There are 2 additional ground floor radiators added since I drew this. The pipework from the boiler to ground is 3 years old, from first to second is probably 2.5 years old. The rest is very old, but only the bed2...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    The system is part new, part old. The Boiler, HW system and all immediate pipework and systems are 3 years old. There is an 'original' section of pipework servicing 3 old radiators (radiators ~20 years old - pipework much older). The run from the boiler is 22mm for most of the way in new copper...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    When this was happening, the pressure was low ~0.5bar. When the water temperature is very low (~20oC), the pressure can be even lower than this. The pressure has always fluctuated quite a lot on the system. Under normal running conditions, it holds pretty steady around 1.5bar, but there are...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    This problem has happened twice now, but this morning, the boiler fired up and worked absolutely fine again. I've recently had the expansion vessel on the CH changed, but there haven't been any other system changes recently. How common is a blockage and how on earth would you go about trying to...

    Worcester Bosch Greenstar Boiler - Temperature Cycling

    My system boiler seems to be exhibiting some very odd behaviour. The heating had been off all day, so the system temperature was around 32oC. I turned the boiler on and it quickly got up to ~65oC. It continued to rise up to 81oC before suddenly dropping back to ~60oC. The temperature then climbs...

    DIN Rail or separate PSU

    Hello, I'm in the process of installing a new 'period feature' in our house - an Edwardian servants call bell system. I've run all new wiring from the call bells to the existing front door-bell transformer which is sited just above the main CU. In order to save me running more wires all over...

    LED Tape Wiring

    Hello, Another question on me on the subject of wiring in LED Tape.. I have ~6m of LED tape connected to a 12v DC power supply. Between the PSU and the start of the tape is a run of around 3m. Because it was a handy size, I've temporarily hooked up the tape with 2 core 0.75mm cable and all works...

    LEDs Tripping MCB

    I can purchase 2 of the 'low inrush' PSU's - but given they would be on the same circuit (switch), that could still potentially yield a momentary surge of up to 40A. Is there any way around that, or shall I just ditch one of the sections of LED tape for a regular light fitting.

    LEDs Tripping MCB

    This is where I am beyond my basic DIY knowledge of electrics, but I came across these: http://www.powerpax.co.uk/power-supplies/low-inrush-current-power-supply-series/low-inrush-current-power-supplies-pln-20w-to-100w-series/ Which claim to be "low Inrush Current" LED drivers, specifically...

    LEDs Tripping MCB

    I have just replaced one of our wall lights with a LED Tape light and associated power supply. As all was well, I replaced a second wall light fitting (on the same circuit) also with a length of LED tape light and an associated power supply. Now, ~30% of the time that I turn those lights on...

    Another Damp Hearth..

    End-state will be to have a kitchen unit in the old fireplace with a worktop mounted gas hob. There used to be an old floor-mounted boiler in the fireplace which vented up a SS liner out through the old chimney. The boiler has been removed, but the SS liner remains. Our builder was doubtful...
