You can’t have an efficiently heated or cooled home without some knowledge of a heat pump’s power consumption. It is something every homeowner in New Zealand should be aware of if they are after comfort but not looking to see their electricity bill run away with them. Modern heat pumps are well suited to that sort of thing.
We have put together this guide to show you the ins and outs of how much power these units consume, what you can do to keep energy costs down and which is the best heat pump NZ has on the market. We will also go over the times you may want to call in the professionals for something like Refrigeration repairs Auckland from Airperfection.
What is Heat Pump Power Consumption?
When we talk about a heat pump’s power consumption, we are simply measuring the electricity it takes to run the unit. But in terms of efficiency, they are in a different league from your average heater. A conventional device will make its own heat, whereas a heat pump merely moves it from one place to another.
Key Insight:
A heat pump typically produces 3–4 units of heat for every 1 unit of electricity used.
