TRV on vertical pipe

[Mike7777777]

Hi

We have a heated towel rail with no TRV, the pipes to and from the rail are all vertical straight out of the floor. I've installed TRVs to horizontal pipes previously (so the valve is vertical), I've also installed TRVs using angled fittings straight into the radiators (valve is vertical).

Can I install a TRV into a vertical pipe with the valve horizontal?

Thanks

Buy a straight valve.

Buy a straight valve.

OK, my understanding of a straight valve is

... but perhaps 1/3 of the price.

So, can the above valve work when the pipe is vertical (Screwfix say no, but that's a small point .... )

Yes the valve type in the link is fine.

There are cheaper makes on the market.

You need to determine the flow before you drain down because they're not bi-directional.
