What is the best way to cut my power bill in Cromwell?
The biggest wins for Cromwell homes are the same as the rest of NZ: install a heat pump instead of plug-in heaters, put a timer on any heated towel rail, and switch to a night-rate plan for the hot water cylinder. The genuinely cold winters that push real-world heat pump efficiency down in this region mean heating is the single largest cost in winter.
