One more thing for when I go back... In the first picture the boiler is to the left of the AAV's then to the right tees off to rads 6&5. The pipe run to the right heads to rads 4&3. In the second picture you see the pipe continue to 4&3...if you zoom in to the back wall where the pipes go down to the rads you can see one pipe loops up quite highly. From sticking my head through the ceiling hatch I reckon this loop is higher than the AAV. Didn't want to crawl across and clip it as was on my own. Is this a potential area for an airlock to 3&4?

Will do...in a couple of days. Hogmanay becons? Only 5&6 have TRVs the others have lock sheild valves. I'll report back

How can you tell if the pump is okay? I read the manual but no fault code exists for such a thing and well, two rads are heating up so...

Bought last week from PlumbCentre, cheapest ones displayed on the counter, think they were 8 quid.

To be clearer about what's what... The bit in the red circle is new. Prior to this all rads (1 to 4) where working fine. 5 is the previous picture of the rad with the tree wallpaper behind it (the big one) 6 is the small one. So, turn on boiler and 1&2 heat up, the others, nothing. ( All valves everywhere fully open, system bled etc) Turn off 1&2 then the lock sheild valve on 6 becomes hot and the rad starts to warm up. So, first question is...is the teed connections in the loft the wrong way around as the hot is arriving at the lock shield side of rad 6, not the TRV side? Secondly, can't figure out why there's no heat to 3&4? Nothing has changed there unless there's still an airlock somewhere or sludge or the pump has an intermittent fault or I'm just in above me head?

Time to head off, it's beer o'clock

5/6 ft. Copper 22mm then converts to plastic before disappearing into the wall

The hot outlet pipe below boiler is roasting but inlet pipe barely lukewarm and I've been here an hour and a half?

Yes, now did all of that and switched boiler back on

Yes

Pipes

I've now shut off the two rads in the front office that were getting heat and now the left valve on the small rad ( the new one) is getting hot!

I'm here now...new pipe from loft comes down from the ceiling and connects to this small radiators. Then carries on to the room on the right. Here

i'll pop over and take some pics, back in a while

Anyone...? Could the flow and return be mixed (i.e. the wrong way around) where its teed in in the loft? System was cold so how do you know which is which?

Pics...

Pics... should these valves not be about 400mm up from the F&R?

@Nickfromwales I've not been out to site but Div has now fitted the air valves and still nothing. He's going to send some pics of the job later but wondered if the pump may not be up to the job as it's an electric boiler? Any thoughts?

Hand tight twisted from the bottom of the flexi. Better to assemble this bit before passing through the tap hole, bit of silicone lube helps... Extra joins underneath are okay as it's all accessible Flexi tail connections are either 8 or 10mm so yes they can be different, all have a rubber O ring for the hand tight seal

Nope none of them, do you fit on both flow and return at the highest point or only on the flow?

I'll get some pics after the holidays @Nickfromwales I got a plumber ( dope smoking Dave) to do it but he's scratching his head at why it's not working. I think my drawing might be wrong and they are connected in parallel. He found the flow and return pipes in the loft and teed off these to the new radiators but as I say only two now have heat. Could it be anything about balancing or commissioning the system?

@Nickfromwales Can you see anything wrong with this? The two new radiators were added to the back shop and system repressurised but only the two rads on the right of the picture are heated? What have I done wrong? Prior to adding the two new rads all four in the front office were hot.

Great advice @Nickfromwales which I've followed. Went to Garscube industrial estate in Glasgow as they have three plumbers merchants close to each other. Young Callum at Plumbworld gave me a small double radiator for free and insisted on carrying it to the car too! Graham's had nothing but phoned another branch who unfortunately had just sent a 4 year pile to the scrap merchant. Next up was PlumbCentre who gave me a huge double for 20 quid, nice fella said he'd give it away but company policy requires an audit trail. Result, and for all the poor experience's buildhubbers are having, remember this, people are generally nice, kind and helpful. I told folk it was a charity job and like, their chance to do a mini DIY SOS but without the publicity. Was met with a huge smile and you're welcome. Few guys in the merchant queue commented too, well done son, you don't ask, you don't get and do on. Nice experience pre Christmas and saved £160 for a couple of hours driving around.

Sending you good karma and best wishes Ali...life is all ups and downs isn't it. After 9 months of being a not very busy handyman I'm back in full-time employment in my old profession and the middle daughter has an unconditional offer at Duke University in the US...dodgy year 2017 but good news at the end. Hope your wife can enjoy your visitors and look back with a wry grin.

It's to attach the freezer door to the kitchen unit door it's hidden (or integrated) behind. Usually white plastic sliders with self adhesive backing. Without a box unit to house it I'd expect it would look ugly and unfinished as although perfectly workable as a freezer. Oh it might not have a door handle though.
