    Hi there

    I recently had a Mira Agile mixer shower installed and it just doesn't get really hot flow of water from the shower head. It's running from a Combi boiler (recently installed and working fine), and the pressures are both equal and strong.

    When I restrict the cold flow into the bathroom, it still doesn't make a difference - still just warm/hot water flow.

    Any advice as to why or a remidy would be amazing.

    Thanks,

    Mitch

    Is that the one that has one control dial that turns it on and does temperature as well?

    How hot is the water from your taps? Maybe the hw output on the boiler needs tirning up...

    I take it that you are pushing in the temp safty button to make it hotter. If so have a look in your manual under commissioning you should be able to increase the temp
    failing that it could be a blocked inlet strainer or faulty thermostatic cartridge.

    It has separate heat and pressure controls.

    Taps are red hot. Shower is hot, just not really hot.

    Well the shower is brand new (and as said it is hot, just not really hot, I don't want it scalding, just hot hot! ;) ), so is the boiler. It doesn't have temp safety button for what I know on the Agile.

    there isnt a red button on this one i dont think tb.
    just one dial that turns it on and adjusts temp. agree that it could be a blocked filter but would checkhw temp at other outlets first

    It is probably just that the maximum temperature is set too low for your particular requirements. This can be adjusted higher quite simply as can be seen in your User Guide. If you don't have the guide you can download it from the Mira website.

    If there is no temp overide button then you might find your shower has been factory set at 42 degrees C
    I would contact Mira and see what they say.

    I know this is 3 years on, but did you manage to get your Mira Agile hotter?
    I have just had one fitted (but combined heat and pressure controls, not separate) and it's not hot enough. Boiler gives 60C which is very hot at taps but not at shower.
    Booklet says factory set at 41, have tried adjusting as per instructions (says 1deg per quarter turn, but turn too much and the hub just gets looser, and would eventually fall off!), still not hot enough. Is this just a poor shower??

    Think he did considering post #13

    Pretty decent shower and a good supplier

    Try turning on a couple of cold taps when the shower is on and see if the temp is hotter
    it doesn't sound right that the hub gets looser, are you turning the correct component?

    Ah yes, I see his post now - it was the first one on page 2 which I didn't navigate to!
    According to the instructions, when you have the single control, it is the hub retaining screw that you turn for temperature adjustment. Since it also retains the hub(!), the hub gets looser! I managed to turn it 4 turns, but it was pretty loose and the temperature was not 16 deg hotter! I wonder if the dual control performs better...
    The booklet also says that the min temp between the hot supply and the outlet is 12deg. Does that mean that I would be limited to 48C in any case - and is that not very hot?

    Check again:

    Turn on the mixer to the maximum temperature and maximum flow and allow the temperature to stabilise. If the temperature is too hot or too cold adjust as follows:
    • Single Control models - Pull the control from the body then unscrew the hub retaining screw with a 2.5 mm hexagonal key. Note! Do not remove the hub.
    • Dual Control models - Carefully remove the concealing cap from the control.
    1. Insert the 2.5 mm hexagonal key into the centre of the spindle and engage with the recessed temperature adjusting screw.
    2. Rotate the hexagonal key until the required maximum temperature is obtained at the shower. Anticlockwise to increase the temperature, or clockwise to decrease the temperature (¼ turn = approximately 1°C).
    3. Once the desired maximum blend temperature has been achieved turn off the mixer by rotating either the hub or flow control (depending on model) fully clockwise. Note! Do not remove the hub.
    4. Refit the hub retaining screw then refit the control (Single Control models).
    5. Refit the concealing cap (Dual Control models).
    6. Check that the shower temperature is correct.


    so, remove the screw and then insert a 2.5 allen key into the spindle

    Not convinced. If you look at the diagram, the hub retaining screw is the thing that you turn with the allen key (single control). The text and diagram don't agree very well, I grant you!
    Maybe there is a second thing to turn if you remove the screw, will have to look when I get home. The spindle may just refer to the dual control though. Am worried about taking the screw out and then the hub falling out, water everywhere!

    I agree the diagram isn't great, but how i read it is you remove the hub retaining screw completely as all it is doing is holding the hub in place. I would isolate the water first though as a precaution

    OK, will investigate again - and maybe call Mira - though getting someone who knows the shower rather than reads the same material is a challenge!

    Wow 3 years I've had hot water!

    It's simple, just remove the control knob and using Alan key to either make hotter or colder.

    I didn't isolate the water, as I adjusted it whilst the shower was on, so I could get the right temp.

    It is a fantastic shower, adjusts itself if someone uses hot water elsewhere so it doesn't go cold.

    Here is a screenshot isolating the bit you need.

    I actually did this last night after previous advice! Stupid diagram that's stumped me from the beginning!
    With your dual control it's just one allen key operation. With my single control you have to allen key the screw off and then separately allen key the recessed adjustment revealed behind. The diagram implies that there's just one thing for the allen key to turn.
    I think it's running hot enough now. My boy will soon tell me...

    Ah yes I see, yes mine is dual control, the cap just clips off and you adjust the screw, it was pretty easy. The shower is ace though.

    Would you believe he wanted it turned colder tonight!!
