    • Giving it a good (4/5) as speed of delivery was excellent but as yet new unit hasn't been installed. But I am assuming there will be no issues in which case I would be happy to upgrade to excellent (5/5)

      William Cochrane

    • Best price I could find on the net.
      Out of stock when I ordered, but I was informed quickly. NSS ordered it in & I had it 48 hours after they received it.
      I was kept informed all the way.
      Very impressed.

      Robert McAllister

    • Excellent transaction component received in excellent condition and as described fast delivery. Would definitely recommend and use again. Thank you.

      Stewart Hodge

    • Quick & simple replacement 'internals'. If your shower has sprung a leak inside the casing just drop one of these in.

      Mr Parker

    • Very fast delivery and an easy fit. Thank you.

      Mr Ashcroft

    • this is the third 'engine' I've had to buy for this installation in 4 years. this one worked once, the other two managed to last just beyond their warranty.
      i've since replaced the whole thing with a different brand - good old Triton, guess what, we've had no problems with that.
      not your fault - you did a great job getting the replacement to me

      Mr Cruise-taylor

    • Much cheaper than buying a whole new unit when limescale got the old one! Very easy to change over so long as you are happy mixing water and electrics.

      Can I replace the old 9.5kw engine on my Quartz electric with a 10.5kw engine without getting a new cover?
      Many thanks
      Michael

      Hello, any change in the KW will require the wiring to be checked/upgraded, by a Qualified electrician

    • I have an Aqualisa Quartz. Shower which is suffering from temperature variation during operation. Is there a thermostat part or do I have to change the whole engine?

      unfortunately the only way to repair the fault you have indicated is the complete engine

    • Have a problem with my Aqualisa quartz electric shower 9.5 kw. When I press the start button the shower operates for approx. 30 seconds and then cuts out, regardless of the setting being on hot or cold. Your help would be gratefully appreciated.

      Hello, it sounds like a faulty solenoid, but you can not get individual spares, you will need to buy a new 'engine'.

    • What guarantee comes with the replacement engine for the aqualisa quartz electric 10.5 kw shower?

      Hello, the warranty is 2 years (against manufacturing defects)
