Efficiency of DHP H12 at higher temperatures
« : 27.10.10 - klo:11:33 »
Can anybody comment on the COP of this pump for higher temperatures please?

All i have so far is:

http://heating.danfoss.com/PCMPDF/DHP-H_datasheet_VDBMB402_ENG.pdf
 
Heat factor  COP 4,4 at bow35
Output capacity  11 kW (At BOW35

Heat factor  COP 3,2 at bow45
Output capacity  10,7 kW (At BOW45

Anybody got a graph of efficiencies?  :-?

Also does this pump supply more motor power for higher KW requirements?  All I have is 2.6Kw for 35 degrees.   Can the user optimise the motor power?

Has anybody here got experience of the outputs of other pumps for higher temperature 40/55-60 radiators?

Any help appreciated.  

If you reply in Finnish i can use Google translator.

Hi Andrew,

How about this? First hit if you put term "DHP-H10" to Google.

Thanks.   info for 45 degrees but not for higher temperatures but it gives an idea of what might be possible.  

Have you any idea what return well temperature you would get in helsinki in a cold winter at the coldest point of the year from 190m single well?
