Possible Causes
Air in heating loops, Undersized or failed circulator, Stuck zone valve, Incorrect boiler temperature settings
How to Fix / Troubleshooting
Safety: Turn off power before purging air or working on valves. Water may be hot.
- 1. Check thermostats: Ensure all thermostats are set to HEAT and above room temperature.
- 2. Feel supply and return pipes: At the Energy Kinetics boiler, compare supply and return temperatures for each zone. A very small temperature difference may indicate low flow.
- 3. Bleed air: Use zone purge valves or radiator bleeders to remove trapped air from the system.
- 4. Verify zone valves and circulators: Confirm that zone valves open and circulators run when their thermostats call.
If heat remains inadequate, a technician should check system design, pump sizing, and boiler firing rate.
