Replacing vented HW cylinder with unvented.

Posted by Mark Huckvale, on
I have an Ideal Icos 18He system boiler with vented HW cylinder. Assuming mains pressure/flow is sufficient, is it possible to swap vented for invented cylinder and run off this boiler?

Yes no problem, make sure the plumber has his unvented licence though as the tank has to be registered with the local authority. Regards Tim
