I have Wirsbo in-floor heating powered by Grundfos pumps.
My well went dry last winter while the pumps were running, and the symptom was that the Grundfos pump was hot and loud. After that (when I got water back), in-floor heating didn't work.
We replaced the Grundfos, but it still got hot and loud. We suspect that air-bleed off was frozen due to the hard water, and when the new pump was installed, the pressure was high due to the air and no water moved and the pumps overheated again. Does this sound right?
Questions:
1. Is there anything I can add to my setup to make it more fault-tolerant for cases where the well runs dry?
2. Any special process we should follow when replacing the Grundfos pump to make the system operational again?
3. Are the other pumps I should try (other than Grundfos) that might be better for this situation?
