Imperial to Metric rad replacement

[bwerd1]

I need to replace some rads downstairs due to age.

It looks like I’ll need to install tails with extensions (20mm either side for neatness) as the new rads would be 40mm to 45mm narrower.

My main concern is that all the rads downstairs have tails with drain off plugs and they are needed as the downstairs rads need to be drained individually during a full drain down.

Do extensions tails with drain off exist? I’m confident enough to swap the rads as I’ve had them off to flush previously but I’d be less confident moving pipe work.

It’s a vented system and for replacing inhibitors so might as well do everything at once.

Or am I planning this wrong?

Thanks

You can still buy imperial sized radiators.
If you like the design of them, Myson Roundtop rads are still available in imperial sizes.
Might not be your choice.

You could fit on of these on one side and the extension on the other
