Thanks to all for the input & feedback. Will get cold-feed/air-separator addressed as soon as I can. Cheers, Rich

Absolutely. Point taken and fully understood! I'm just interested in understanding the intent of the system set up, and whether I should consider any changes. Sorting out the air-separator (and cold feed) is a now a given. If I could, I'd also quite like to procrastinate about it until...

Yep, I did mean fixed speed 1 on the pump. Thank you very much for ABV+TRV explanation. Starting to make a bit more sense now. I'll give it a whirl on ABV(max) and AutoAdapt. This post came in useful http://www.diynot.com/forums/viewtopic.php?t=267969 ;-) Do non-condensing boilers have...

Indeed it is - even on speed 1. So, does that mean it won't confuse the AutoAdapt? Out of interest, why would I need a bypass if I don't have pump over-run, and i'm not fully TRVed..

Assuming turning a bit cap doesn't change the setting, it's on '1'. Is that highest or lowest? The Alpha2 instructions talk about manual bypass and automatic (thermostatically controlled). In this context, is my valve manual? The instructions say 'see setting the pump' for manual which would...

Thanks for the quick answer. I would like to keep it simple :-) and stay open-vent. Does air-separator do anything for dissolved air, or is it only bubbles? Is there any benefit to replacing/keeping. Still mystified why it only pumps over on CH+HW. Is system higher +ve pressure in this...

I'm baffled now. I'm starting to wonder if there something fundamentally wrong with the pipe layout in my central heating system: http://richandkath.co.uk/pipework.jpg The problem is that it pumps over a slight trickle, but ONLY when both HW and CH are on. Separately, its fine. If I...
