Running an old Apollo system in a third-floor flat. System has been knocking a lot recently so being smart I thought I'd bleed the rads. No air came out apart from rad closest to boiler, which had a ton in it. I did not realise you need to turn off the pump tho, silly me.
Today I woke up and found i had no heating and hot water is only mildly warm. The only radiator with any heat is the one closest to the boiler, and it's only hot at the top. All other radiators are almost stone cold.
What's the verdict? Airlock? Sludge? Help!
