EDIT: you're right, as of June last year a tempering valve is required when replacing HWU's http://www.fairtrading.nsw.gov.au/bi...ol_devices.pdf

Can you adjust the valve at all to provide a better mix?
There was a flow restriction in the line - plumber replaced the old restrictor with a new one and now you probably need a full harness to stay in the shower.
