I have been looking for radiators with top feed connections. This is a for a bungalow with a concrete floor and suspected leaks in the buried CH pipework. I want to move most of the radiators anyway, so the logical thing is to install new CH pipe through the loft and drop down where needed. But don't want visible pipes or boxing everywhere. Most of the walls are solid, chasing is messy and a pain in the proverbial. I have heard of top feed radiators with an internal dip tube for the water inlet. This sounds perfect for my needs particularly if floor to ceiling height, but can't actually find any on the market. Does anyone know of any vendors that still exist for this type? I don't mind paying a bit extra within reason but I'm not really interested in 'statement' modern art sort of things.
