1st problem - downstairs rad's cold. Thought I'd try fernox restorer.
Drained system all ok - put 1 ltr of fernox in header tank - filled again - still no heating downstairs. Hot water boiling. Left for a couple of weeks..Try again... Drain system opened upstairs bleed valves watched bucket's fill with black water, then opened downstairs kitchen rad .. no air, just lots of water ?, which eventually stopped. Then opened all other downstairs rads only air at bleed valves . Shut all bleed valves/drain cock, refill system - bled all rads (downstairs 1st ) - now all rad's cold !!.
Pump's working ok. The top feed into the cylinder is very warm ( from pump )- bottom cooler. Across the cylinder's side conn's is a valve with a thermostat attached to cylinder , the o/p from this valve is very warm. So I have two very warm o/p's from the valve and one cooler one coming from the cylinder coil. Does anyone make see through pipes ? Can anyone help please.
