    But you won't have a pocket for anything larger than an 11inch thermostat, take a look back to the picture in post #11, your immersion heater will look very similar.

    If this isn't satisfactory then a Willis heater may give you more hot water in the tank? https://www.boards.ie/discussion/2058243718/fitting-a-willis-immersion-heater

    Wake me up when it's all over.

    The problem with the 11" stat and a 24" element is that, depending on HW usage, you could end up with only "11 inches" of HW at 52C to 60C and "13 inches" at maybe ~ 25C, the 11" stat will only ensure a "24 inch" volume at 60C from a cold cylinder and if all the hot contents are used up then again. The Willis heater is certainly worth considering or a destatification pump.

    I was looking at the destat pump alright, solar diverter has an output to power it too so it would all be run from solar. Part of me also thinks maybe to make the investment in a stainless steel tank with two side elements and never have to worry about it for years.

    A bit of caution if you intend to have a coil as well, the bottom immersion element is normally above the top of the coil so you may end up only heating ~ 50% of the cylinder, back to square one, you may be able to get a cylinder with the element below the coil so have a look.
