Heat Pump Running Costs Calculator
Calculate your daily, monthly and annual heating costs. Compare heat pump efficiency vs other heating methods.
Reduce Your Running Costs
🌡️ Optimal Temperature
Set to 18-21°C in winter, 24-26°C in summer. Every degree higher/lower increases costs by ~10%.
⏰ Smart Usage
Use timer functions and avoid frequent on/off cycles. Steady operation is more efficient.
🧹 Regular Maintenance
Clean filters monthly and service annually. Dirty filters can increase running costs by 15-25%.
🏠 Improve Insulation
Better insulation reduces heat loss, allowing lower settings and significant cost savings.
Frequently Asked Questions
How efficient are heat pumps vs electric heaters?
Heat pumps are 3-5x more efficient than electric heaters. They move heat rather than generate it, using 1 unit of electricity to produce 3-5 units of heat.
What affects running costs most?
Usage hours, power rates, unit efficiency (COP), and outdoor temperature. Colder weather requires more energy.
Are heat pumps cheaper than gas heating?
Generally yes in NZ. Heat pumps typically cost 30-50% less to run than LPG and are competitive with natural gas.
