OT swept Tees
Another off topic question for all you clever people...
I need to find a pair of "swept" tee junctions for a central heating system...
The idea is to streamline the flow in one direction to keep flow rates and efficiency high...
Im after 22mm copper solder or compression type swept tees...
I have checked the usual suspects, Screwfix, Focus and a couple of other places and they only seem to sell what appear to be normal Tee
junctions...
Can you actualy buy such a swept Tee, or am I just dreaming?
If so, where can I aquire a couple?
Loads of places sell larger bore plastic swept Tees.. like this

Yes you can get them, somewhere like plumb centre or PTS should keep them.

A couple of those in a CH system will make sod all difference to the overall flow and efficiency, save yourself the trouble and just use T's.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Its not your normal central heating system and the manufacturor of the heaters has specified these to make balancing the heat output easier....Not
sure if its just hype...

Its hype. Balance the system, (if it needs balancing), with the lockshield valves. Thats what they are for.
If its broke, fix it. If it aint broke, take it apart and find out how it works!

The only time swept tee's are needed is when radiators are run from a single pipe system which is not a very efficient system. If you are
desperate to acheive perfect balance use a reverse return system. Basically this means that the first radiator on the flow from the boiler is last on
the return to the boiler 2nd rad on flow 2nd to last on return etc etc until the last on the flow is connected to the first on the return. Sounds
complicated and is awkward to install.   
After reading this again it dosent sound right the first rad is connected to the flow pipe nearest the boiler and is connected to the return pipe
furthest from the boiler. Alcohol and plumbing dont mix hic

he crucial thing here is getting a balance between the two boilers.....They both require the highest flow rate possible on the shared flow and
return....
So swept tees were suggested to help this along..
