Radiators in series - good or bad?
 

I'm pricing up radiators right now - and there is a very good deal on
" radiator packs" in the Stelrad Softline range.

Bascially you choose whatever you want up to a "total btu" figure

Downside is maximum length of any rad (in this deal) is 1200mm, and in
some locations I need something a good bit bigger.

So - how practical is it to run two rads in series - i.e. straight
horizontal copper pipe out of the first and into the second, with trv
and lockshield at the respective further ends?

I figure it would only cost me two threaded male compression fittings
(and bit of pipe) to jump between the two rads- and have the two
function as one.

Any pitfalls here?

no big deal. Historic CH systems often had *all* the rads in series

I don't know how historic you're getting here. I've not come across any
such. Even single-pipe systems don't put the radiators in series: each
rad has a bypass pipe in parallel with it, and the rad+bypass
combinations are in series with each other. This is quite different to
what the OP is asking about, if you think about it.

brought next idea :

I cannot think of any serious ones....

The flow might be very slightly less, due to the extra restriction and
the second radiator from the flow side will run a little cooler, due to
the water having lost some of its heat in the first one.

If you link at top and bottom, then it's in effect exactly one
radiator. I've seen that done to make a radiator folded around
a bay window.

However, it's generally better to have multiple separated heat
sources in rooms which require a higher heat input to give more
even heating, so why not take advantage of the extra radiators
by separating them?
