Hi, I'm not a plumber but a retired householder who used used to do some of my own plumbing. The CH system in our house was installed before the days of compulsory trv's and just has a lockshield valve and a control valve on each radiator. Many of these have not been touched for over 20 years and so start to leak when any adjustment is attempted ( should be no surprise!) . I now want to replace all the valves in the house ( except the handful already replaced in emergencies ) with new trv's and new lock shields . I quite like the idea of an electronic programmable on each radiator. Pegler used to do something like that but they seem to have given up on the, and there seem to be some reasonably priced German ones about but I'm not sure what they do. Can anyone suggest such a trv? I don't want to go in for one of the fancy systems controlled from a smart phone, just independent valves that are a step up from manual trv's .
Another question , if I may , is it still a good idea to balance the system these days or do you just leave up to the trv's to sort that out?
