Hi,
I currently have standard (wax) Honeywell TRVs on my radiators. The heads screw on to about a 30mm valve body.
I've given up with the slow response times of these TRVs and was thinking about trying a Drayton TRV4 on one of the radiators, given the liquid sensor and 'A' rating.
However, I'm guessing the only way to do this will be to replace the complete valve body as the Drayton head is a different fitting to the Honeywell body? In which case, its a bigger job than I was hoping and one I probably won't try just to test the Drayton on one rad (particularly with fairly new carpets).
I'd be very grateful if anyone can confirm the Drayton heads won't fit the Honeywell valve bodies and whether there are any alternative suggestions.
Many thanks and best wishes,
Damian
