Hi Andt,

To answer your queries:

1. The rads I mention are not as old as the antique types you mention
so I guess I mean old versions of more modern panel types.

2. I thought it was the typical triangle shape heat distribution but
it also sounds a bit like the top only and either end of rad heating
you suggested (I get the impression I am, not beong clear!)- when we
cleaned one out last year, it worked perfectly for a couple of weeks
before going back to the orignal useless heat distribution.

3. Yes, the new rads are in BTU/hr so I guess the existing pipes
should be ok. Phew.

I think we'll get a bloke round to change the rads and see how we get
on then. Fingers crossed it will be fine!

And get a powerflush on "all" pipes. Then run the system on 80C all the
time. If you are getting new rads get low surface temperature rads as these
can be safely run at 80C.
