Not All Heat Pumps Are Created Equal! Your Savvy VIC Guide to Choosing the Right Size, Features & Future-Proof Tech

Not all VIC heat pumps are equal! Plum Heating & Cooling's savvy guide to choosing the right size, features (COP, LFP) & future-proof tech.
Not All Heat Pumps Are Created Equal

So, you’re excited about upgrading to a super-efficient heat pump hot water system for your Victorian home – fantastic! You know about the potential bill savings and those juicy government rebates. But now you’re facing a sea of options and wondering, “Which one is actually the best for me?”

It’s a critical question because, you guessed it, not all heat pump hot water systems are created equal! Choosing the right model goes beyond just the brand name; it’s about matching the size, features, and technology to your family’s needs, your home, and our unique Melbourne climate. Picking the wrong one could mean not enough hot water, or not getting the best possible efficiency and savings.

Don’t worry, Plum Heating and Cooling is here with your savvy Victorian guide to cut through the jargon and help you select a true champion – a system that’s perfectly sized, packed with the right features, and truly future-proof!

Size Matters (A Lot!): Getting the Perfect Fit for Your VIC Home

First up, let’s talk size. It might not be the most glamorous topic, but getting it right is essential.

  • Too small? Get ready for those dreaded cold showers, especially if everyone needs hot water around the same time.
  • Too big? You’ll pay more upfront and could be heating more water than you need, which isn’t peak efficiency.

While a very general guide is about 50 litres of hot water per person per day, a more reliable approach for Victorian homes, considering households can change over a system’s 10-15 year lifespan, is to size based on the number of bedrooms:

  • 1-2 bedrooms: A tank around 150-225 litres is often suitable.
  • 3 bedrooms: Look in the 225-300 litre range.
  • 4 or more bedrooms: You’ll likely want 300 litres or more.

Also, chat with your Plum Heating and Cooling expert about your family’s hot water habits: How many bathrooms? Simultaneous showers? Do your dishwasher and washing machine heat their own water? If you plan to use timers with solar PV, a slightly larger tank might be beneficial to store enough heat between cycles.

Beyond the Brand: Must-Have Features for Your Victorian Heat Pump

Once you’ve narrowed down the size, it’s time to zoom in on the features that will make a real difference to performance, running costs, and longevity here in Victoria.

  • The Efficiency King (COP): The Coefficient of Performance (COP) tells you how efficient the unit is. Aim for a COP generally above 3.5. Crucially for us, ask about its performance at lower ambient temperatures (like 5-7°C) to ensure it’s still a star performer during those chilly Melbourne mornings.
  • Winter Warrior Mode (Frost Protection): Essential for Victoria! Ensure the model can operate efficiently down to at least -5°C to -10°C and has robust frost protection or automated defrost cycles. This prevents ice build-up and maintains performance when the temperature plummets.
  • The Green Heart (Refrigerant Type): Look for systems using low Global Warming Potential (GWP) refrigerants. R744 (CO2) – used in some Reclaim Energy models – or R290 (Propane) are much kinder to the planet than older types and CO2 models often excel in cold climates.
  • The Sound of Silence (Noise Levels): Heat pump hot water systems typically range from 35-55 decibels (dBA) – like a fridge or AC unit. If it’s near a bedroom or neighbour, aim for quieter models (<45 dBA if possible). Some CO2 systems, like those from Sanden or Reclaim Energy, are noted for very quiet operation around 37-38 dBA.
  • Warranty Wisdom (Your Peace of Mind): A solid warranty is crucial. Look for good coverage on the tank (7-10+ years), compressor (5+ years), and other parts/labour (2-5+ years). Remember, the VEU program requires a minimum 5-year total warranty for eligible systems.
  • Smart & Thrifty (Timers & Solar PV Optimisation): To truly maximise your savings, especially if you have rooftop solar, look for systems with smart timers or dedicated “solar modes”. This allows you to schedule heating to use cheaper off-peak electricity or your own free solar energy. Efficient systems from brands like iStore are also great contenders here.
