Grundfos GO Balance Application

[hallra]

Hello Forum,

I have installed a Grundfos Alpha 3 pump, which comes with a companion mobile application called 'Go Balance', the two interact to allow the installer to "easily" balance the CH/HW system.

Now stupidly, Grundfos in their almighty wisdon, have decided that it would be very clever to not provide any manual or documentation on how to use the 'Go Balance' application....

As such, when it comes to ask for certain inputs to be manually entered by the installer, the installer (me) hasn't got a clue what should be entered or even how to calculate what should be entered.

I am stuck on two inputs:

1) Required Heat Power (W/m2)
- Examples given:
Old Buildings, Not Renovated 110-160
Built 1978 - 1983 95-115
Built 1984 - 1994 80-100
WSVO 1995 50-70
ENEV 2002/2007 35-45
EnEV 2009 25-40

From what I can gather, this is a static figure that is based on some sort of thermal standard the house has been built to... WSVO, ENEV appear to be German building standards...

2) Inlet Tempreature
- It has a description of temprature of water entering radiator.

Would this be a desired tempreature or should i be getting out my tempreature reader and take the temprature coming into the radiator.

My apologies if these are simple questions that are easy to answer, but being a DIY enthusiast rather than a professional, I'm am a little lost...

I have searched forums, google and Grundfos website without a hint of what is needed to be entered... Grundfos technical support was hopeless...

- I have logged a complaint with Grundfos, that may or may not lead to something...


Thanks in advance

Richard.

when was your house built

rough guess put 110 in the first one

55-60

Sorry should have mentioned that... "palm hits forehead"...

The house was built in 2015.
- Don't ever by a new build, it is built cheap as chips and nothing works..

 

[ShaunCorbs]

35-50 then

Thanks for your help Shaun.

Could you explain how you come to this answer, as I would like to try to understand the meaning of 'Required Heat Power' and the equation W/m2...

 

[ShaunCorbs]

In short w per m2

As new build are supposed to be insulated to the hilt they don't require as much heat so pump doesn't need to work that much / slower speed

I presume watts per metre square is a standard industry measurement, wonder why I couldn't find any information on it.

I agree that new build should imply that it should be insulated to the hilt, unfortunately mine has been built so badly, it has air leaks everywhere, making the insulation useless... I have been battling the builder (Persimmons) to get it corrected, especially as I'm disabled and the cold screws me... Finally after 3 years, LABC are taking it on, so hopefully sometime next year, the house might actually have decent insulation/warmth...
