Hi folks, first post and new to plumbing so please bear with me. i am in process of renovating an old home i bought (all i could afford :)). I will be getting a plumber in to do some stuff but i want to buy materials myself so i wish to check 2 areas.
1) I am completely refitting bathroom. i need to replace radiator in there as it is in bad shape. i want to fit a towel warmer/radiator. not so concerned about the heat output as it is a small room and always warm. i have seen one on offer from scewfix direct (link below) and wonder if the TRV pack that comes with it will fit ok to pipes coming out from the floor. i have seen it somewhere else but the TRV pack was connected to pipes coming from the wall. excuse my stupidity if i have missed something but im not sure if this pack will work with pipes coming from floor. thanks.
2) the rest of my radiators are reasonable and apart from painting them i wish to replace the radiator valves on both ends as mine are horrible looking. i would like to put TRV on each of them (7 in total). again with each pipes are coming from the floor. am i correct in sayin that i need Angled Thermostatic Radiator Valves as opposed to straight and lockshield valves for other end. (all pipes 15mm so ok there). i am confused by the following lockshield valve as it says 15mm x 1/2 inch.........wat is the 1/2 inch part is this till ok for mine if used with a 15mm angles TRV
The valves pictured are angled which allows the pipe to run at 90* to the towel rail, by the sounds of it you need straight valves this allows for the pipes to run straight from floor into valve than into towel rail.
90* angled rad valves are more for normal radiators or for towel rails where the pipes come out from the wall underneathe rail connection. the pipes coming.
1/2 inch refers to the barrel that fits inside the rad . Most older rads have 3/4 inch nuts connecting to the radiator valve. So you have two choices.
Find out which size yours are by offering up a half inch barrel to those on your existing valves, if they are the same size simply replace valves.
Or if new 1/2 inch barrel has a slightly smaller nut than existing(3/4 inch) you will have to remove barrels with large allen key, ptfe tape new 1/2 barrels and screw into rad than tighten valve on to pipe.
