Firstly hello to the forum, I am a DIYer so I will apologise for that first!
I will start from the beginning!
I recently done some work on my bathroom, when I removed the bath panel I found the hot water coil feed and return running around the bath behind the panel. In my haste to get on, I yanked the bath to hard and an elbow on the coil feed parted resulting in much water everywhere! I patched that up with a couple of pushfits and got on.
A couple of days later the heating pump packed up (dribbling water out and into the electrics), I have a Boulter Bonus oil fired boiler with two pumps one for heating circuit and one for the indirect hot water circuit. I assume the two circuits join as the system is filled from the F/E tank which runs thro the hot water coil. I just don't know where this join is and how it is configured. The house is very long and thin (25m long but only one room wide), the boiler is at ground level at one end of the house, with the hot water cylinder in the middle of the house on the first floor. There are 13 rads on the heating circuit.
I bought a cheap pump and fitted it, all appeared to be fine. I drained the system to remove a rad in the bathroom which is being altered, changed the pipework to reposition the rad on another wall in the bathroom, but this will go back on at a later date as I have some decorating to do first. Refilled the system and since then I have had problems with the rads heating up. Thought that maybe the cheap pump was the problem so swapped it with the Wilo which was on the hot water circuit, didn't make any difference.
Drained down and refilled several times, at this point I must say the system is dirty, I removed a rad in the sitting room as this is where I drained the system and flushed it thro with a hose. It was full of black oily sludge. This has made a little difference as I am able to get a little bit of heat to some of the rads, but the return pipe is cold/lukewarm.
Have I got a stubborn airlock or is the circuit blocked somewhere. It doesn't matter how careful I am when I refill it keeps up with this problem. Excuse my ignorance here, I have a drain point at the heating return at the boiler this is the lowest part of the system if I attached a hose and flushed the system thro with mains pressure would this force the airlock out of the F/E tank. I appreciate what ever I put in will come out of the overflow but is there anything wrong with trying this?
I cant find any motorized valves, I assume as there are two separate pumps for heating and hot water I don't need motorized valves???
HELP!!
