Understanding Thermostatic Valves
Hi, I'm considering the thermostatic valves to add to my existing tado smart thermostat set up. I understand that I can use these to avoid heating rooms I'm not using.
What exactly do the valves consist of? Do I just remove the head (I believe this is the top bit where you would traditionally change the temperature) or is it the full body?
My guess is that if it's just the head, it mates with the plunger in the valve body and controls things from there but would be grateful of some guidance.
I'm trying to work out how easy a job it is to fit myself. I'm reasonably handy, but I don't fancy going as far as draining a system.
