Should we use the Heatpump?

The Energywise website (run by the NZ Government agency EECA) has a calculator which allows you to work out how much electricity your appliances are using.  https://www.energywise.govt.nz/tools/running-costs-calculator/#!/

According to this site a 6kW heatpump uses just over 1kw of power per hour.  That means it costs about 28c per hour to run a heatpump.  So here are some comparisons to get you thinking about whether you should use the heatpump and keep warm.

One $5.00 coffee

​

= 17 hours of running your heatpump

= running your heatpump for 1 hour per day for 17 days

So if each person in a 5 bedroom flat gave up just one $5 cup of coffee at some stage during the year, the whole flat could run the heatpump for 3 hours every day for 1 month.

One $20.00 Big Mac large combo delivered by Uber Eats

​

= 71 hours of running your heatpump

= running your heatpump for 2.3 hours per day for 1 month

$25 of liquid refreshments

​

= 89 hours of running your heatpump

= running your heatpump for 3 hours per day for 1 month

= running your heatpump for 6 hours per day for 2 weeks.

So if each person in a 4 bedroom flat gave up $25 of refreshments at some stage during the year, the whole flat could run the heatpump for 3 hours every day for 4 months.
