hot water

  1. C

    Should I replace my (possibly 20 y/o) Ideal Mexico 2 boiler with a modern combi?

    The boiler is working fine but is an old conventional boiler, and what is quite annoying is that the central heating system has no 'y valve' so you can't have hot water without turning on the heating (in the summer we put the thermostat on minimum but it still comes on). I had some plumbing work...

    Hi, please see attached photos (blue: cold mains to boiler and kitchen after bathroom. Red: hot from boiler to bathroom. Yellow: gas to boiler. The other pipes are the radiator pipes that do run across under the pipes at the radiator ends - again too close to them) is this okay? I’m concerned...

    Megaflo D70 1 Shower

    We have a Megaflo D70. Should it be able to keep up with the use of 1 shower continuously? We seems to run out of water after a 10 minute shower at the moment. I don’t think there is another boiler in the system - should there be? ... the property has electricity only.

    Foolproof CH & HW programmer

    Can anyone recommend a really straight-forward simple programmer for my elderly parents who need a replacement. It's probably going to need to be analogue unless there is something special designed for old folks. Many thanks

    Glow Worm 38cxi ignores hot water control

    If you set the hot water temperature to zero on the front panel control the hot water system never comes on. If you turn the control to the very minimum setting that will make the hot water circuit active, the burner lights and the hot water output temperature quickly rises to 65C (maximum). It...

    Overflow

    Hi The overflow pipe is dripping. I have been researching how to stop it but am now confused as to where the pipe comes from. In my naivety I thought overflows just came from heating systems. I have now read it could be from the toilet. How do I find out which it is coming from?

    Grant vortex combi boiler losing pressure

    I have a Grant Vortex 26, and it is losing pressure. It can be at 1 bar in the evening, and be down to 0.3 bar in the morning. When the heating is on, it holds pressure, but as soon as you turn on hot water somewhere in the house the pressure drops. I thought the two systems were separate, but...
