Gary, I think you've misunderstood what I meant by valve body. The body is the metal bit with water flowing though it. Changing that as I've just done is a rigmarole as I've described. The head is the thermostat, the vulnerable bit that's also easy to change. Changing to a different make of valve I'm obviously replacing both the body and the head. The Peglrs head looks less vulnerable to knocks than the Drayton.
Without TRVs it's more or less impossible to make my heating work sensibly. For example as the sun moves round the house different rooms get solar gain and the TRVs regulate the radiators accordingly. They also automatically adjust to warmer and cooler days.
I could use a central thermostat and have done in the past in other houses. The result is that the temperature is always wrong in most parts of the house.
