Radian Posted February 7, 2023 Share Posted February 7, 2023 I've always used the rough-and-ready technique of starting with the closest rad to the boiler and setting its lock-shied to a quarter turn or so, then gradually increasing on that for subsequent rads in the system - out to the furthest one - ending at a couple of turns or so. Seems a bit unscientific, so I thought I'd be clever and make me a fancy, internet connected, differential measurement kit: This merges the live temperature readings with some handy data from the boiler etc. and pings them up to my phone for display. The screenshot was the first quick test on a nearby radiator. Great I thought! Looks super useful. Until, that is, I tried to use it. 🙄 The thing is, the first rad I tested it on was a big one and was evidently well balanced already (using my old method). When I started with the radiator closest to the boiler (a small one) I could not get a delta greater than 6oC. The reason seems to be that operating the lock-shield in the almost off position alters the volume of flow so much that the flow temperature falls as well as the return. The delta stays put whatever you do. Opening the lock-shield enough to get the flow temperature within, say, 10oC of the boiler flow temperature means losing the ability to control the delta as it's already pi$$ing through. Different radiators scale this problem in inverse proportion to their size so while I felt I was getting somewhere with in a handful of rooms with large rads, I went back to the old method for the majority of the radiators. Anyone got any pro-plumbing tips to offer me? Link to comment Share on other sites More sharing options...

Looks like a good destination for a evening outing. Cheers! Actually have some reasonable pubs around the place but none within walking distance... as defined by how long my bladder will hold out 🤣 Link to comment Share on other sites More sharing options...

JohnMo Posted February 8, 2023 Share Posted February 8, 2023 Hope that fixed the balancing, beer and food, or does that lead to an unbalanced system? Link to comment Share on other sites More sharing options...

Everything gets better with a few beers. Or just drink enough that you don't feel the cold 👍 Best to line the stomach first of course Link to comment Share on other sites More sharing options...
