Vertical Radiators

[NigelE]

I am Renovating my house and have decided on Vertical radiators. the radiators have arrived with 6 ports. can these radiators be plumbed from the top or, must they be plumbed from the bottom? Anyone have any advice?

Just make sure they're hung and plumbed in the right way - I'm sure someone with proper plumbing knowledge will be along shortly. I have two friends who both went for vertical radiators and they didn't work properly. After all sorts of shenanigans with plumbers/manufacturers it turned out in both cases the radiators had been hung upside down. Now rectified and working perfectly.

Thanks Celeriacacaca, Will do.

because hot water rises, if you plumb a radiator just from the top, only the top will get hot.

If you want to, you can plumb ordinary rads inlet at the top, and outlet at the bottom (opposite end)

vertical rads are intended to be plumbed at the bottom, and have internal baffles to encourage the hot water to fill all the columns. If they are upside down these baffles will be in the wrong place.

Thanks Piglet John, it was confirmation that was required more than anything else. I do have a follow up question though! Are there any specific problems or do you have any additional advice about bedding the pipework into the walls?

If you have a wooden floor, I would certainly run the pipes under the floor. If they must come down from the ceiling, you would do better to have them exposed, or one day somebody will drill or nail into them. It is undesirable to make a big chase into a wall as it will be weakened. If you have an old 9" solid brick wall I suppose you could do it. There are rules I have forgotten about acceptable chase depth as a percentage of the wall thickness. It is different for horizontal and vertical chases.

Exposed pipes can be painted to match the wall.

Thanks John.

Or you could box them in . The trouble with exposed pipes they are dust and web prone, and difficult to paint behind the pipes. I boxed em in kitchen and was quite inexpensive to make.
Very interesting regarding plumbing in vertical rads though , might come in handy one day when I get a new rad for the bathroom. The current one is going rusty at the bottom, and is so narrow it's next to useless

The pipes I boxed were floor to ceiling by the way, not parallel floor running.
