Drayton TR4 are the kings of the TRV. If you can afford them, go for them.
What are those westherm lookalikey's like Ray? Any good. Having issues with bulldogs
They sell pretty well Tom, and the return rate is only a few per 1000 - IIRC about the same as Honeywell. But when I looked at the TRV4 figures the other day, we had not taken a single one back under warranty in a whole year. And we sell many thousands of them - and not a single return. I can't think of another technical product with a zero return rate.
