TRV Question

[robertito]

I know thermostatic radiator valves are customarily on the radiator inflow side, but is there a good reason for this, or could one equally well go on the outflow side ?

It would have to be a bi-directional valve (most are nowadays) or they can make a right din.

Thanks gigz, I've seen valves described as 2-way but I didn't know what it meant. I thought perhaps it was because the connectors allowed the valve to be fitted horizontally or vertically. Incidentally I don't really see how a vertical TRV can work properly as it has a hot pipe just underneath it ! Any thoughts on this ?

I know a few plumbers wont fit them vertically for that reason, but in my (humble) opinion i dont think it makes a big difference, i always ask the tennant /homeowner which way they want them.

Thanks, gigz!
