Hi!
I've drained my system in order to replace two broken radiators. All the old ones I've had off to rinse through, and I've fitted thermostatic valves to upstairs ones.
Put heating on yesterday. All okay after bleeding, except one upstairs radiator. I left the bleed-screw right out for about an hour or more, and thought there was a slight hissing, but it stayed cold at the top though hot at the bottom, and no water spirted.
Drained system again today to fix a leak. Refilled. Now several of the radiators are odd. Some hot at bottom not at top, one hot at top and not at bottom. Some of the pipes are cold as well.
Help,please!
