Ok, in our front room we have two large cast iron rads (about 3 years old). We have known for some time that they cause the temp to overshoot quite badly due to latent heat etc. So now I am trying to mitigate this but not having much success.
I have tried using the TRVs to limit the temp but because these rads get so hot they overwhelm the TRVs causing them to cut the water supply too early - even before the room gets up to temp. Its like trying to tune an old radio !!!
So, what are my options ? heating water temp ? lockshield valves ? - what do heating engineers usually do to tackle this ?
Thank you.
