    Idea is use grey water in gas pipes as energy source for heat pumps.

    Water pipes run at lower depth. Grey water in gas pipes would likely freeze.
    It creates ice slurry... would this not create havoc in the drains.

    Small flows of cold are hard to stop freezing

    Pretty sure water doesn't burn as well as natural gas so every house (or at least large areas of houses) would have to be changed over at the same time. Compare that with other large scale roll outs like smart meters.
    Well that one certainly brought a long laugh on a dull day!

    I liked the bit about the UK having no shortage of water, and the tonnes of ice falling out of the heat pump and down the drain...
    Isn't it a bit early for this one - perhaps more fitting for the beginning of April ?

    Really outside the box !!

    Grey water ?

    How about BLACK water...


    "Harnessing the heat of a sewer system is just one way of reducing the carbon footprint of heating".

    I am sewer this will interest lots of folks & therfore invert all comments...

    Yes, it is likely to be a great suc-cess. (Don't think on that one for too long; it's distasteful.) Just flying off in my new jet. I call him Basil.

    My house is above the meeting point for many sewers around us. I live in fear of a brown artesian well erupting one day.

    The temptation remains strong to build an ostensibly ground-source heat-pump that is in fact poo-source by virtue of running the collectors alongside the foul pipes...
