    Boilermate 2000 Hot water or lack of

    Thanks Softus! You were correct the PHE was scaled up on one side. I have replaced the PHE and we now have lots of reliable hot water. I guess this will be an annual job for me now with the rate at which the scale builds up! Many thanks for your help. Woody

    Boilermate 2000 Hot water or lack of

    Can you give me a step by step guide to changing the plate heat exchanger? How much water is contained in the store? How long does it take to drain? Thanks

    Boilermate 2000 Hot water or lack of

    Thanks Softus, How easy is it to replace the heat exchanger? Is it something I could do myself? As this will be the second time in 18 months will a water softener help? Or is it likely that the heat store side will get scaled up even if the DHW side doesn't? Many thanks, Simon

    Boilermate 2000 Hot water or lack of

    Ok I connected the DHW pump as described and ran the hot water. The water read 65 and then dropped steadily to 22 after a few seconds, then it fluctuated as before (ie between 22 & 30). The store temp was reading 73. Does this mean the pump is faulty? Or could it be the plate heat...

    Thanks for the link to the servicing manual. So using the wiring diagram on page 25 (ie boilermate with switch facility). I should connect cores from numbers 16 & 17 from the PCB and core 13 from the terminal block to which? Also do I leave 18 connected to the PCB? Thanks

    I had this exact same problem 18 months ago. It was caused by scale build up in the plate heat exchanger. Had that replaced and the hot water was as good as new.

    Boilermate 2000 Hot water or lack of

    I have managed to locate the supply to the DHW pump, however I'm not sure where you want me to connect this to. We have the boilermate 2000 with switch and there are a lot of wires. Is it the live, neutral and earth cores going into the PCB? If so should I leave them connected to the PCB and...

    Boilermate 2000 Hot water or lack of

    Hi, thanks for the reply. The header cistern has plenty of water. The store temp is reading 72 and the min/max values are set at 71/74. If the demand segment is a red line next to the digital number at the bottom of the display, then yes that comes on when a tap is opened. The DHW...

    Boilermate 2000 Hot water or lack of

    Hi, we have a problem with our boilermate 2000 providing hot water. Most of the time it is just cold, however on occasion we will get normal hot water but it doesn't last long. I have already replaced a faulty DHW sensor, but that didn't help. The plate heat exchanger was changed 18 months...
