I didn't get to see it sadly. Water from the rads is slightly off clear if that makes sense.

So, the long and short of it: Engineer arrived, diagnosed old pump as shot, replaced in 10 mins, no more noise. Score.

I hear ya. Hopefully he'll be an approachable engineer with fixing it all in mind.

Best be careful then. I'll play it by ear. It's not a BG installation though.

Yes that's exactly what it is. I'll mention it to the engineer on Saturday. Like I said, to be fair the system has ran faultlessly for the best part of three years so far.

Just been on to BG. Another engineer is attending.

That's what I though. We have a Worcester condensing boiler (Greenstar?). Its ran very well since it was fitted about 6 years ago.

Well the Auto setting is pointless. Nothing is warm this morning. It wasn't moving enough water. Set it back to II. The drone noise from the pump is horrible though, enough to keep you awake. I'll contact BG this morning and get a different engineer in.

I see what you're saying but why is it only doing this after 3 years? It's ran faultlessly up until now so I can only presume the system is ok in principal.

Can confirm the arrow on the casting points upwards and therefore in the correct orientation to the pipework. The highest radiator in the house is in the bathroom, the first radiator after the pump. Water flows well when bleed screw opened. Appreciate the help.

As I understand it, the feed comes into the bottom of the pump via the aerator (I think that's what it's called). Then up to the diversion valve. Bleed screw cap at the top of the feed to the HW tank.

Here you go.

I've ran the pump on setting III for 5 mins. Bled any air from the bleed valve, just off the feed to the HW tank. A little air came out. The radiators were bled yesterday by the BG engineer. He left it on the II setting. I could hear air in the pump and it was generally a bit noisy, like a...

Right I see. I've set it to a slower setting and it's definitely quieter. I'll see if it manages to keep the radiators warm. It's only running at 3 watts.

Afternoon all. I've been looking in this forum for similar problems at it seams the Alpha 2 isn't without its problems. We've got a Grundfos Alpha 2 15-60 130. Fitted by British Gas 3 years ago, it's been fine but this winter it's be really quite noisy regardless of what setting I switch it...
