    That has given me a thought. There is a silicon or plastic substance you can get that is used to change your car colour. I believe it peels off. I know that taxi owners, whose car may not be the right colour to obtain a hackney licence, use it to ensure compliance.

      A silicone skin is definitely going to act as additional insulation that would slow the response of the temperature sensor so even if there was a skin that fitted it I would not go down this route without using an external temperature sensor.

        That's the PlastiDip I was referring to. EDIT: or maybe vinyl wrap? I agree with DBMandrake that a silicon type cover is going to start having some noticeable insulation properties, so an external temperature sensor probably would be best in that scenario. But the plastidip might not have as much of an effect as it would be a thinner coating.
        Do we know whether the HR91 coupled with an external sensor can replicate all the functionality of the HR92, ie actual/set temperature display and local control of the zone? As the HR91 would be easier to cover, not having to deal with masking round a display and the control wheel and so might be an easier (if more expensive) option all round.

            The AVS90 always reminds me of a Doctor Who Cyberman.

              Hi all I'm not the OP but moved into a new place with cast iron rads in Anthracite Grey so decided to paint my HR92 as they didn't look too great in bright white against the grey. The rads are powder coated in gloss RAL7016 so I bought a spray can of the same colour. I removed the top knob and the bottom wheel, masked the display off and rubbed the casing down with 1200 grit wet and dry.
              A couple of coats left me with the following, I'm very pleased how it came out:





              Looks much better than white. I found that even when unpainted the internal temperature sensor doesn't work very well on cast iron rads as there is too much influence from the direct heat of the radiator, so am using an external sensor to get a sensible temperature reading. I haven't yet compared painted vs unpainted as per the previous discussion in the thread, but will try it out and see what the results are, even though an external sensor is the only real option anyway.

                That looks fantastic, if you ask me. And if you are using an external sensor then there is no issue either.

                  Looks good but also looks like a lot of work!

                  Lets hope you don't need to do a warranty claim on that HR92 - I think the reseller would not be amused...

                      Thanks all, @dbmandrake actually it was hardly any work at all, I'd say it took about 30 mins not including drying time of course! I actually did just one first as a test to see what the finish was like and to make sure it didn't affect any functionality, and when I was happy with that I did another 5 and sprayed them all up at the same time.

                      I also did a test to compare painted and un-painted following the previous discussion, and can confirm the colour makes no difference to the temperature measurement (I used both HR92 units configured with internal sensor for this test):
