Energy Kinetics Domestic Hot Water Production Failure

No domestic hot water or hot water runs out quickly, but space heating works.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed DHW circulator, Fouled plate heat exchanger, Faulty DHW sensor, Stuck DHW zone valve

Safety: Water may be hot; use caution.

1. Confirm DHW priority: Run hot water and check that the Energy Kinetics control indicates a domestic hot water call.
2. Check DHW circulator temperature: Feel the DHW circulator on the boiler. It should get warm and vibrate when running. If it stays cold, it may not be operating.
3. Inspect mixing valve: If a thermostatic mixing valve is installed, ensure it is not stuck or set too low.

If hot water remains inadequate, the plate heat exchanger may need cleaning or replacement.
