Attached is diagram of a hot water system, the boiler will be oil fired and emitters will be 3/4" baseboard. I decided to use delta T pumps to vary the flow rate based on the heat load. Do you see any issues using these types of pumps or setup?
In the scenario 1 zone is calling for heat, the load is low compared to the boiler capacity. How does the boiler react? Meaning does the boiler cycle on and off, to avoid reaching the boiling point of water. Which I would think would be a bad thing in a hot water system. Pleading my ignorance if someone could explain...
Thanks in Advance
