Hi

One of my friend has had a quote for mixergy unvented cylinder 150l

The installer mentioned the cold water header tank in the loft will be required but the CH header tank will not be required.

I may be wrong but my understanding is unvented is mains pressure

Can anyone please confirm if the cold water header tank is needed

Will 150L be enough for 4 bedroom with 5 people

The installer mention to my friend the cylinder will heat 5 times faster than his current indirect cylinder

In my opinion I feel cold water header tank is not required and mains pressure is required but haven't really done any work on mixergy just need someone opinion
