Best pump for a 55 radiator closed pressure central heating system.

I was just about to post a picture of my infected wound but decided against it at the last moment.

It does sound that there are more than a couple of issues with the set up the pump possibly being 1 of the.

You could look at separating the floors out and fitting an individual pump to each circuit, less work for each pump and if one fails still got the other 3 floors going!

You say you keep adding apartments and rads, every time you added a rad did you take the flow and returns back to the primaries of from the nearest feeds?

Are all the rads in the system re-balanced when you add a new one?

The rads are 600 x 1000 are they sized for the room at -20 you want bigger than standard I would think, our calcs work on about -5 I think.

Is the underfloor ran from the same boiler as the 55 rads? rads pulling 100ish KW how much does the underfloor pull all from a 66kw boiler?

Just a couple of thoughts for you to mull over!

someone should have spent some time designing this system before they started..

I think he's got the message, help cannot be at hand with such a mess, must be something to do with that EU we are in,
I know how I am going to vote if I am still alive.
