Hello everyone, first post here (as you can probably tell).
My condo was built in 2008, and some time before my unit was sold to the first buyer in 2010, the builder and the designer of the hydronic heating system both went out of business. I am trying to get a better understanding of the system, and the few HVAC people I called said I need to call the company that sold the system.
Hot water goes from the gas water heater into a circulator pump (Grundfos UPS15-35SFC), and from there into a manifold that sends the heated water to each of the radiators. The return from the radiators then goes back into the water heater.
The pump does not feed the hot water faucets, just the radiators.
The circulator pump gets power when any thermostat calls for heat. It also gets power periodically from a wall-mounted 24-hour timer.
My main question is why does the pump need to run daily?
Thanks ... Mike

- For health reasons (making sure hot water doesn't sit for a long time in the pipes before going back into the water heater)
- To prevent the pump from freezing (I mean mechanical freezing, not icing up)
- No good reason
