Column radiator microbore

[tomsim]

Can column radiators perform ok on microbore? Would be 8mm copper

 

[denso13]

Yes, no problem.

So I'm getting heat to the flow then the heat is working is way up and across the coloums. But the return is only Luke warm

 

[denso13]

Is the radiator heating ok?

 

[tomsim]

Not great yet. The flow pipe is hot going too it. Then the heat has started to work it's way up the columns and through the radiator. However the return pipe is only Luke warm.

Installed the correct way up? Lockshield open correctly?

 

[tomsim]

Yeah I installed the arrow so it flows through the correct way. The baffle forces the flow up the radiator heat is going up to the top of the radiator it is just struggling to return by the looks of it

 

[tomsim]

Any other ideas. Could it still be an air issue?

 

[denso13]

Turn all of the other rads off and see if it is any better.

 

[tomsim]

Because the radiator is getting hot. But can feel much hear on the return. Water must be flowing through it

 

[tomsim]

If no flow it wouldn't heat up at all?

 

[CountryFan]

If no flow it wouldn't heat up at all?

Correct. Have you turned others off? Did balance the system?

 

[tomsim]

I did turn the others off and it started to perform better. Though I still wasn't getting much heat on the return pipe to it. I think the boiler cut out water at required temperature. I'm going to try again tomorrow. Just wondered if there was anything I could try

Sounds like the system needs balanced.

Though I still wasn't getting much heat on the return pipe to it.

Never mind that, you want the radiator to heat, not the return pipe.

Thanks so the return could still be coldish but the radiator could heat as it is dipisatating most of the heat through the radiator
