Move pump?

[Irish]

Evening all The neighbour of where I'm working today asked me to have a look at their ch today said it's not getting hot in loft conversion, old system, been p flushed, boiler looks big enough too handle the work (at a rough guess), pump is on the ground floor right at floor level, pipe work looks good enough for supplies to upstairs. Would it help if I moved the pump to the airing cupboard on the first floor? as it seems a long way for it to try and pump it round
Thanks in advance

I would be looking at air locks and balancing before doin all that hard work

 

[Irish]

Yeah sealed system so shouldn't be airlocked and apparently the guy that did the plumbing already balanced it

 

[Puddle]

Loft conversion often equals builders plumbing work,pipe runs to rads could be a bit imaginative !

imho

 

[Irish]

Haha true puddle!! But I can see it's nice neatly clipped 22mm running up in the airing cupboard but it could be a lot different under the lovely chipboard floor upstairs

 

[SimonG]

Well if it's clipped and 22mm it wasn't a builder!

pump on the way out????

Has it ever worked properly?

As it is a sealed system have you tried raising the pressure say to about 1/34 - 2 bar?

 

[Irish]

No only had 20 minutes fiddle with it as I didn't want to br there all evening, what would raising the pressure do ?

Really better to rule out partial flow due to airlocks or balancing issue (despite it's supposed to be done).
If there is a hot water cylinder, make sure it has a valve to balance it, as the coil is a massive short circuit if not balanced.
Can easily be the pump unable to do the height. If nothing else obvious, & pump is not blocked, change pump to a new, compatable type for size of house & type of pipework & rads - ie restrictive or not.
I would suggest a 6m head pump for a
small/medium house. I have seen fairly new pumps in perfect clean condition suddenly unable to do the harder parts of a system & a new pump sorts it - can be a head scratcher as it is rare. I assume the pump motor was going slow.

You sure Obama ?

Raising the pressure would have the same affect as raising the head.

What is the system pressure at present?

 

[Irish]

1.5 bar

What about larger pump ?
