1. NZ Government Heat Pump Guidelines

The New Zealand government provides guidelines for heat pump sizing to ensure energy efficiency and optimal performance. Proper sizing helps maximize the Energy Efficiency and Conservation Authority (EECA) benefits and potential subsidies.

2. How the Calculator Works

The calculator estimates heat pump requirements based on:

• Room/area size in square meters
• Geographical location (North vs South Island)
• Insulation quality of the space
• Primary usage (heating, cooling, or both)

Note: This tool provides estimates only. For precise calculations, consult with a certified heat pump installer or use official government tools.

3. Importance of Proper Sizing

Details: Correctly sized heat pumps operate more efficiently, reduce energy costs, and last longer. Oversized units short-cycle, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Measure your room dimensions accurately. Consider the building's insulation quality and whether you need primarily heating, cooling, or both functions.

5. Frequently Asked Questions (FAQ)

Q1: Are there government subsidies available?
A: Yes, EECA offers various subsidies and programs for energy-efficient heat pumps. Check the EECA website for current offers.

Q2: How accurate is this calculator?
A: This provides general estimates. For precise sizing, consult with a professional installer who can perform a heat loss calculation.

Q3: What's the difference between North and South Island requirements?
A: South Island generally requires more heating capacity due to colder winter temperatures.

Q4: How does insulation affect heat pump sizing?
A: Well-insulated spaces require smaller capacity heat pumps as they retain heat better.

Q5: Where can I find certified installers?
A: The EECA website maintains a list of approved suppliers and installers eligible for government programs.
