Luckily the radiators will hide the extra holes. Also the spacing between tubes isn't exactly 50mm like booklet says, it's 49.5mm so over the course of 11 tubes it ends up 5mm out so I've compensated for that as well this time so hopefully it'll be spot on.
Did some more work today, but didn't turn out much of a success.
Finished assembling the passive radiators and then did some leak testing but getting a lot of leaks so I think I'm going to have to break out the PTFE tape and I think I'll also try and get some black silicone sealant as well and try again.
More than enough, the Cape Cora tubes are all in parallel so the flow restriction from them is pretty low. I'm going to have a flowmeter in the loop so I'll be able to check what kind of flow I'm getting.
Not much, only the pump really. The fans will be controlled down to ~200/300rpm normally so will be inaudible relative to the pump and I'll have them only speed up if the water temperature increases beyond a set point. I'll need to play around with this I think.
Stealthed the fans with black tape to cover up the labels/wiring.
Looks alright even with the flash.
The radiator clips in effectively using the fan frame. I had to snap the corner webbing off with a pair of pliers to get it to fit.
Also lesson learned with the Cape Coras. Don't remove the tees - getting them reinstalled water tight is a complete mare. Gave up in the end and started again.
