I have two radiators that are hot at the top. From about half way down they
are cool to almost cold at the bottom. seems strange to me. I would have
thought they would be hot all the way down. Any ideas ?

Ditto ... just get the rads ouside and flush both ways with hose pipe
and watch the orrible gunk come out :-)
Probably cheaper just to buy a couple of new rads. They are
reasonably inexpensive and you would know then that they were all
clear. Stelrad do a Softline rad which is a simple but attractive
household rad. All you should need to do is turn off the valves at
both ends then remove and replace rads. Just make sure before you
start that the wall brackets are in the right place.
They should be hot all the way down. Have they always been like this or did
they once work OK then stop working OK? Have you got a conventional boiler
with an unpressurised system or have you got a combination boiler with a
pressurised system? What happens to the two non-heating rads when you turn
all the others off? Do they heat up properly?
Yes theydid work.
Have you got a conventional boiler
It looks as though I will have to tough it out this winter and strip the
system down in the spring to give it an overhaul.
I had an old cast iron boiler for 25 years and it was good at heating
radiators and water.
It finally gave up and I had this new (6 Years ) boiler and new radiators
fitted with pumps and switches fitted. It failed to fire up the day after it
was fitted and has never been satisfactory.
Now if I turn it up too far it kettles. So I turn it down and it is not hot
enough. I have just purchased a pipe thermometer and the best I can get
from the outlet from the boiler is about 60C.
At the radiators this equates to 40C. or less with the added complication of
cold bottoms on two of only four rads. When the Hot water is on the
radiators drop to about 32C
If I had any money I would rip it all out and start again but like a lot, if
not most people today, I have enough debt to sink me without taking on more
spending although I have to balance this with the rising cost of fuel.
