Panel convector radiators

[Pete~M]

Hi. I've been trying to find one of these radiators with 3/4" bsp inlets, but I can only seem to find them with 1/2". Does anyone know of a make that does this, or would it have to be a different style of rad required?

Some Commercial radiators have 3/4" tappings,

Why do you need 3/4 tappings ?

Heating system is an old one pipe commercial system, there's an issue with flow through the designer radiators in the property. I'm looking to change the rads, and wanted to keep everything in 3/4".

be carefull, lots of designer rads will not work on a one pipe system, check before you buy if the have a baffle fitted

Yeah well that's the current issue. So was just trying to find a conventional panel convector, but with 3/4" tappings.

You would be better contacting the Manu and asking if their rads will work on a 1 pipe system, they work OK but need an awful lot of balancing to work properly, not really a DIY job, many heating engineers wouldnt go near it never mind a DIY job

Is the system pipework copper or malleable iron?,
you will also need 'high flow' radiator valves specifically for one pipe systems.

It would probably have been designed around old cast columns, they came with 3/4" or bigger tappings, they not an option?

Be lucky to find 3/4" domestic panels with that size, probably be bespoke or commercial .... commercial would tend to be big sizes though through 3/4".
