oventrop uni LH

Paul Pollets

The"LH" is a thermostatic radiator valve head. The Unibox is a different product. The LH head can be placed on any radiator or baseboard element with the correct valve body. A "remote" actuator uses a 6' or 12' cappilary tube which is mounted at 5' and controls the radiator. The Unibox has a limit of 12K BTU's for adding a radiant zone, usually when radiators are installed.

UNI LH

Getting ready to install a Oventrop Uni LH non electric stat for our radiant. I've never installed one and was wondering what roughly should the hieght off the floor be. The instructions are say "install so it senses true room temp"
Any tips are welcomed.
Thanks

Would be the answer if it was a standard “electric” stat…however you are dealing with a stat of a different color.
The nice thing about the Uni-Box or a LH is the fact they do not show a temperature, only numbers, (3) is about 68 deg. It senses this temp. at the stat (68 Deg. Set @ 3) no
matter what it’s height off the floor. I tell contractors & Home owners this simple rule of “European” comfort: If you get to cold you simply turn the dial to a higher #...if you get to hot you turn the dial down to a lower #, when you find “your” comfort zone lock it in place and leave it alone.
The only thing we can not over come is Solar Gain.
I have placed Uni-Boxes and LH's as low as 4’ off the floor, however most homeowners like the convenience of the stat being placed higher on the wall.
The LH is really nothing more than a Non-Electric "Radiator Valve"... and how high do we install Radiator Valves? Thats right, as high as the Radiator.

the uni-box plus is for a add on Radiant Zone, that is piped off a High temp loop, yes it does have a limit, my rule of thumb is 300 Sq. Ft. of radiant floor...just a fyi.

I called oventrop today. They said between 24"and 36" off the floor. The part number in case anyone wants to know is 101 22 96. Thanks for the help and pictures. I don't know about anyone else, but: it seems when you work on your own heat system it takes longer then normal.
