How do you measure a radiator ?

How do you measure a radiator, ready to change it to a new double one ?

Last year I decided to change a towel rail so measured centre of pipe to centre of pipe thinking this was correct. The plumber had actually said it's a 600mm rail, but as he hadn't actually measured it, I assumed he was wrong. He returned about a week later to carry out several jobs, but when he came to fitting the towel rail there was a problem. Luckily I managed to take it back and buy the 600mm one, which I should have bought in the first place.

Now we want to replace an existing single radiator with a double and it'll be fitted by the same plumber so I don't want to make the same mistake again. He thought I was a chump then, so not sure I want to be a bigger chump now.

From side to side surely?

I would measure the widest part of the rad, namely the points at which the tails (readipes) meet the rad.

https://companyblue.co.uk/blogs/new...commend you to measure,on the towel rail size.

You may however find that the old rad is imperial rather than metric (which is the norm these days). If so, you will need a slightly larger or smaller rad.

With a tape measure

Sizes are typically height first - top or bottom end to end - not the centre

Towel rads are alway outside edge to outside edge, pipe centres are a supplementary measurement.
