My gran has thermostatic valves fitted to her radiators. I seem to remember
you could get "locks" for these to prevent them being turned up too high or
down too low. Does any one have any experience of these locks or an addy to
a website were these locks are for sale, can I fit "locks" to the existing
valves or do I have to replace all the valves with "lockable" ones?
addy not usable (not that you would try it)
Many valves have the locks built in. You remove the head from the valve body
(there is usually a big nut to undo). Under the head are lots of holes, one
per degree C. You take the locking pin from the parking position (i.e. 30C)
and put it where you want it. Make sure the valve is set to 0C before you
insert the pin. Then reattach to the valve body.
