Loops in plumbing

[amwc]

Hi
Just wondering what the general consencus was on having plumbing that drops down to come back up in a central heating system? i.e. the hot pipe comes out of the rad drops down then goes along a bit then goes back up before joining the main feed. would this cause any problems apart from when draining?

no

probably 90% of systems are fitted this way at some point

thanks I was just wondering if it would effect the principle of hot water rising and weather hot water could in fact sink too?

 

[twgas]

As it's pumped there will be no heat rising effect.

That's not significant, assuming you're using a pump.
You need air vents on all high points and drain cocks on all low points.

 

[amwc]

got the vents and drain points but its not pumped at the mo its on a back boiler. would you recommend putting a pump in?

 

[twgas]

How old is this non-pumped (hard to believe)back boiler system?

 

[amwc]

about 3 months old?

 

[twgas]

I'm thinking you are not at all conversent with pumped and gravity systems.

 

[amwc]

Maybe not, but there is definately not a pump in this system hence my post in the first place asking about shape of the plumbing? Its a back boiler running three rads and hot water?

 

[twgas]

Are we talking solid fuel? if so I apologise as it may well be gravity (I don't do solid fuel)

 

[tamz]

Even if it is solid fuel it is not being described properly or it wouldn't work.
Very unusual to have 3 rads fed on gravity. That went out in the 60's.

 

[amwc]

yeah it is solid fuel sorry? would love gas but none in the village? so it is a bit like back to the sixties or even 20s but i'm just trying to get the best out of it. so you would put a pump in the system somewhere?
