Radiators

[Irish]

So, I have a tall radiator climbing the wall of my sitting room.

It is a B&Q special and puts out about as much head as hand warming glove.

1) Does the quality of a radiator make much difference to the heat?

2) Are there rolls royce brands for heat quality?

Thanks.

Maybe it's full of air or the valve isn't fully open/faulty?

assuming it's actually getting uniformly hot (as in there's water circulating in it), then it;s heat output is governed by it's surface area, water temp and surface finish.

all rads usually come with a BTU/Kw rating, looking at B&Q:

B&Q Vertirad Vertical Panel Radiator White 445 x 1500 mm - 2088 BTU
small conventional Kudox Double Radiator 600x600mm - 3662 BTU
Large conventional Kudox Double Radiator 600x1400mm - 8198 BTU

see the difference?

Yeah, noticed this when recently sizing up a trendy vertical radiator for my living room. Despite some of them being enormous (and enormously expensive) none of them produced more heat than the 'normal' relatively small double panel radiator that is there now. Gave up on the idea for a large room but may get something fancy for the bathroom.

This makes sense. The heat is consistent but i can put my face against it even when it is at full tilt! The room previously had a double rad and was boiling. Now we struggle to warm the room.

I wonder if it's plumbed the right way? I fitted a tall radiator with inlet and outlet at the bottom so I had to put a blanking plug (supplied) in the middle so the hot water was forced to the top.

Then there is definitely a problem with the rad or more likely the install .

Have you got the flow temperature high enough? You need 70 degrees plus for a radiator to get near it's rated output.

Even at full tilt it has issues.

The secret is out though. I had two weeks there this year (June and August - sunny, warm, great craic).
