Please our team of Engineers are contemplating using either deionised water or water gotten from water softening process as boiler feed water. Please kindly advise.
Thank you.

Depending on the boiler temp/pressure and the planned chemical treatments neither of these sources may be clean enough. Softening, replacing Ca ions with Na still leaves a lot of 'stuff' in the water.
Go back to the manufacturers guidelines and talk to water treatment experts.
