Boiler wiring - Danesmoor + 2 external pumps

[James Palmer]

Hi All,
Thanks for the replies.

The 2 pumps are Grundfos UPS15-50x18 MKII, but not connected like in the link they are totally separate. They only have 3 input's L/N/E.

The pumps were put in to aid circulation as the 15/19 boiler wasn't really up to the job - I believe.
So I got a slightly bigger danesmoor (20/25) and was hoping it maybe a like for like swap, but only realised I had got the utility model so that's the reason for the questions.

Thanks

Speak to Worcester as it may be possible to swap the control module from one to the other

Have you always had independent control over the heating and hot water?

 

[James Palmer]

yes, is that unusual?

No but without seeing the system, pipe layout, etc it's guess work.

Hi Lee,
yes it is this actual one, that was me being tired and it has got the black control box dangling inside the boiler, so I have it already wired effectively (I guess) and just need to hook up the L/N/E to the new boiler from this?

Is it a grundfos pump plan system?

The control box/wiring centre should be fixed external to the boiler not dangling inside.

That will change when I sort it ....

Just read the OP again and your old boiler had an internal programmer so you are going to have to get a two channel programmer. Do you have a room thermostat and cylinder thermostat?
