Hi

I would like to convert from an internally located mains mains cylinder to an outside located heat pump hot water cylinder.

I'm unclear on whether I need Auckland Council Building consent? The AC website says I do but I think that may be for newly installed HP systems ie new houses.

What is confusing is I've found a Building Act 2004 exemptions document (August 2017, version 3) that indicates I don't need consent (via exemption 38).

I rung the council to enquire but haven't heard back yet.

Any help appreciated.

Simon
