I turned the thermostatic valves off on two heaters in unused bedrooms. They've been off for a long while, over a year.
I've turned the valves back on but the heaters don't get hot. I've tried bleeding them. Both pipes going into the rads are cold.
It's a Megaflow system. Here's a pick of the expansion tank and dial readings.
Is there anything I can do, or is it call the plumber time?
