Warning; Using 15/50 pumps for the DHW

Post  mike on Tue Mar 29, 2011 1:03 pm

I keep coming across Gledhill units.
Which have the normal every day Grundfos pump fitted.
Instead of the original.
The impellers are different.
The normal every day Grundfos pump IS NOT SUITABLE when a Plate Heat Exchanger ( PHE) is being used and where sensors are involved.

I quote the following;

Hello Mike,
Further to our telephone conversation, I can confirm that the Grundfos pump we stock is in fact different to the standard one that most merchants stock – ours modulates down to about 50 – 60 volts whereas the standard ones stop at about 150 volts.
I hope this answers your question.

Regards,
Paul Nettleton,
Spares Manager.
