Changing radiator on one pipe system

[Matt0029]

I have a rad. To swap and pipework for the rad. To hide in a wall on a one pipe system. The rad. That is in is a 1600 double but only 300mm heigh. Its an original rad. From when the system was put in 70s I think. Will a 1600x600 double panel/convector work on this system?

Or do I really need to recommend converting to a two pipe system? The boiler that is in is a worcester bosch. Only 3 years old. Not sure why it wasn't converted then. The customer has just bought the house.

If it’s not broken why fix it?

One thing to be aware of is that they use special TRVs that are quite pricey (£40+ each).
