Heating your home through Dunedin’s long, cold winters is a reality every local homeowner faces. With power prices rising and older homes still common across the region, choosing the most efficient and cost-effective heating solution matters more than ever. Heat pumps have become a leading choice, but how much does it really cost to run one in Dunedin?
At McClelland Refrigeration, we’ve spent over 30 years helping homeowners and businesses across Dunedin and Otago stay comfortable all year round. In this guide, we’ll break down the real-world costs of running a heat pump, what affects your power bill, how to maximise efficiency, and how our services can make a tangible difference to your comfort and energy usage.
Key Takeaways
- Heat pump running costs in Dunedin depend on home size, insulation, temperature settings, and unit efficiency.
- Our expert installations and regular maintenance services keep systems running at peak performance.
- For many homes, switching to a well-installed heat pump offers long-term savings over electric or gas heating.
- We offer in-home assessments to recommend the right-sized unit for your space.
- Professional servicing helps reduce energy waste and extend the life of your investment.
- Our expertise extends to commercial climate control, refrigeration, and integrated systems.
What Affects Heat Pump Running Costs in Dunedin?
Dunedin’s climate means heat pumps often run for longer stretches, especially in older, less insulated homes. The cost of running your heat pump depends on several factors that we assess during every consultation:
- Size and model – Larger systems and older units may draw more power. We help clients choose the most energy-efficient model based on their space, number of rooms, and layout.
- Temperature settings – Setting your heat pump to 20°C instead of 24°C can significantly lower energy use without sacrificing comfort.
- Usage habits – Running a unit all day versus targeted use during the morning and evening can make a noticeable difference to your power bill.
- Insulation levels – Homes with good insulation require less heating to stay comfortable. We often recommend reviewing insulation as part of any upgrade conversation.
- Installation quality – An incorrectly installed system can cost you more over time. Our team ensures proper placement, accurate sizing, and complete testing for every install.
- Local environment – Homes in exposed or coastal parts of Dunedin may require more frequent heating cycles, and our technicians take these microclimate factors into account.
How Much Could You Expect to Pay Monthly?
Most homeowners in Dunedin can expect monthly running costs between $40 and $120 during the peak of winter, depending on house size, insulation quality, and how the heat pump is used. For a smaller, well-insulated home using a hi-wall unit wisely and intermittently, bills might sit under $50. Larger, open-plan homes or villas with older insulation and extended heating periods can fall on the higher end.
For ducted systems servicing the entire home, expect slightly higher usage but a better comfort-to-cost ratio, especially when replacing multiple standalone heaters. Our in-home assessments help clients understand these trade-offs clearly and confidently.
We also factor in your home’s layout, sun exposure, ceiling height, and preferred living zones. Our recommendations aim to maximise comfort in the spaces you use most, while keeping costs manageable and efficiency high.
Keeping Your Heat Pump Costs Low All Year Round
Our services are designed to help you get the most out of your heating system every month of the year. Here’s how we help you reduce unnecessary energy use:
- Book a seasonal maintenance check before winter or summer to clean filters, inspect electrical components, and ensure the system is running efficiently.
- Use heat pump timers and Wi-Fi controllers to pre-heat rooms before use, avoiding unnecessary all-day operation.
- Maintain stable temperatures instead of constantly switching your system on and off, which can consume more energy.
- Consider upgrading to a modern inverter model with higher energy star ratings if your current unit is over 10 years old.
We supply and install a wide range of heat pump solutions tailored to Dunedin conditions, including hi-wall units, floor consoles, in-ceiling cassettes, and ducted systems. Our advice is grounded in experience and backed by local knowledge. Whether you’re heating one room or an entire home, we provide the right system with the right controls to keep you warm efficiently.

Why Our Installations Make a Difference
Installing a heat pump correctly is vital to its performance and your power bill. Every Dunedin home is different—from heritage villas in Mornington with high ceilings and draughty windows, to compact modern units in Mosgiel. Our qualified technicians assess your home’s unique layout, construction materials, insulation quality, and usage habits before making recommendations.
We supply and install trusted brands like Fujitsu, selected for their performance in cold climates and reliability over time. Each installation is carried out with precision—from correct outdoor unit placement to avoiding airflow blockages and ensuring your system runs quietly and effectively.
For ducted systems, we take extra care with insulation and sealing to prevent heat loss between rooms. These details can significantly impact how much power your system uses and how long it lasts.
Comparing Heat Pumps to Other Heating Options
When we speak with Dunedin homeowners, many want to know how heat pumps compare to alternatives. Based on our experience across hundreds of installs, here’s what we’ve found:
- Wood burners are great for ambiance and strong heat output, but they require regular fuel, proper storage, and can be difficult to regulate. They also may not meet clean air requirements in some areas.
- Electric heaters are easy to use and affordable upfront but become costly with prolonged use. Many of our clients are surprised by how quickly the savings stack up after switching to a heat pump.
- Gas heating provides fast warmth, but ongoing fuel costs and emissions can outweigh the benefits for many families.
Heat pumps offer the advantage of dual-function heating and cooling, better air quality, smart control options, and significantly lower long-term operating costs when installed and serviced properly. They are also more sustainable for households looking to lower their carbon footprint.
