Bleeding calorifier

Sort of as per the title. Have discovered a slight leak on one of the unions in the engine bay taking water to the calorifier. Question: if I take it off, replace the PTFE tape and do it up again, will I need to bleed the calorifier and, if so how do I do that ? Thank you.

With ours open the hot bath tap as this closest to the calorifier and wait until the water runs at a steady pace. i.e. not accompanied with any air.

I suspect he's talking about engine coolant circuit going to the calorifier coil rather than the main tank contents of the hot fresh domestic supply itself which your method would bleed air from.

 

If I'm correct in my assumption,  I have a bleed valve in the high point of both the feed and return lines close to the calorifier for the purpose OP refers to, but I fitted them myself!  They work a treat... but only if you have them. ;)
