Why is my Daikin EHVH08SU23EA6V not heating or cooling properly?
- GGary Lewis DDSAug 4, 2025
If your Daikin Heat Pump isn't heating or cooling as expected, start by checking the temperature setting on the remote controller, referring to the operation manual for guidance. Also, ensure that all shut-off valves in the water circuit are completely open, the water filter is clean, and there's no air in the system, purging if necessary. Confirm the water pressure is above 1 bar, the expansion vessel is intact, and its valve is open. Check that the water circuit resistance isn't too high for the pump, consulting the ESP curve in the "Technical data" chapter. Verify the water volume in the installation is above the minimum required value.
