WASTING SOLAR POWER? PAYING TOO MUCH FOR EV CHARGING?

Without a smart system, your EV might be charging from expensive grid power even when your solar panels are producing excess energy.

💸

HIGH CHARGING COSTS

Charging an EV on standard grid electricity can add over $1,000/year to your bills – negating the savings of going electric.

☀️

SOLAR OVERFLOW

When you charge without a smart system, excess solar often goes to the grid for mere cents, while your EV might draw power from the grid.

MISSED OPPORTUNITIES

Time-of-use discounts, free solar hours, and your home battery's output – a regular charger can't take advantage of these, leaving savings on the table.

📱

JUGGLING APPS & TIMERS

Manually switching plugs or using multiple apps (solar app, EV app, etc.) is a hassle. It shouldn't require constant attention to charge efficiently.

Heat Pump Hot Water: Energy Savings & Efficiency Explained

February 26, 20255 min read

Hot water is a necessity in every household, but traditional water heating methods can be expensive and energy-intensive. With rising electricity costs and a greater focus on sustainability, many homeowners are switching to heat pump hot water systems for a more energy-efficient and cost-effective solution.

But what exactly is a heat pump hot water system, and how does it help reduce energy consumption? In this guide, we’ll explore how these systems work, their benefits, and why they are a smart investment for Australian homes.

heat pump

What Is a Heat Pump Hot Water System?

A heat pump hot water system is an advanced water heating technology that uses heat from the surrounding air to heat water, rather than relying on traditional electric or gas heating elements.

This system operates similarly to an air conditioner or refrigerator, but in reverse:

✅ It extracts heat from the air using a refrigerant.
✅ The refrigerant is compressed, increasing its temperature.
✅ The heat is transferred to the water, efficiently warming it.

Unlike traditional electric water heaters that generate heat directly, heat pumps move existing heat, making them far more energy-efficient.

How Does a Heat Pump Hot Water System Work?

A heat pump water heater consists of three main components:

  1. Evaporator Coil – Absorbs heat from the surrounding air.

  2. Compressor – Increases the temperature of the refrigerant.

  3. Heat Exchanger – Transfers the heat to the water in the storage tank.

Step-by-Step Process:

1️⃣ The system draws in warm air through the evaporator coil.
2️⃣ The heat from the air is absorbed by a refrigerant, turning it into a gas.
3️⃣ The compressor increases the pressure, raising the refrigerant’s temperature.
4️⃣ The heated refrigerant passes through the heat exchanger, transferring heat to the water.
5️⃣ The refrigerant cools down and returns to the evaporator coil to repeat the cycle.

This process allows heat pump systems to use significantly less electricity than conventional water heaters.

How Does a Heat Pump Hot Water System Save Energy?

1. Uses Up to 75% Less Electricity

Heat pump hot water systems can be three to four times more efficient than traditional electric water heaters. Instead of creating heat, they move existing heat, requiring much less power.

✅ A standard electric water heater may use 4 kWh of electricity to heat water.
✅ A heat pump system can achieve the same result using just 1 kWh.

This reduction in power consumption leads to lower energy bills and significant long-term savings.

2. Takes Advantage of Renewable Energy Sources

Heat pumps work best in warm climates like Australia’s, where they can efficiently extract heat from the air year-round.

✅ They can be paired with solar power to reduce grid electricity use.
✅ They operate efficiently even in cooler temperatures, unlike solar-only systems.
✅ They require less backup heating than traditional electric systems.

By harnessing renewable thermal energy, heat pumps help reduce carbon emissions and overall electricity consumption.

3. Reduces Peak Electricity Demand

Many households use hot water during peak electricity pricing periods (morning and evening). Traditional electric water heaters draw large amounts of power during these times, increasing costs.

✅ Heat pumps use less power overall, reducing peak demand.
✅ They can be programmed to operate during off-peak hours, further lowering costs.
✅ Some models feature smart scheduling, optimising energy use based on demand.

This means households can maximise savings by heating water when electricity is cheaper.

4. Minimises Heat Loss Compared to Storage Heaters

Traditional storage water heaters continuously heat and reheat water, leading to standby heat loss. Heat pump systems:

✅ Use better insulation to retain heat longer.
✅ Require less reheating, reducing energy consumption.
✅ Can be installed closer to usage points, minimising heat loss through pipes.

By maintaining water temperature more efficiently, heat pumps prevent unnecessary power waste.

5. Long-Term Cost Savings on Energy Bills

Although heat pump water heaters cost more upfront than standard electric systems, the energy savings offset the initial investment.

✅ Households can save hundreds of dollars per year on electricity bills.
✅ The system typically pays for itself within 3–5 years.
✅ Many models qualify for government rebates, making them more affordable.

Over the lifespan of 10–15 years, a heat pump system can save thousands of dollars compared to electric water heaters.

  • Medium households (3–4 people) → 250L–300L tank

  • Large households (5+ people) → 300L+ tank

2. Noise Level

  • Some heat pumps generate noise similar to an air conditioner. Choose a quiet model if installing near bedrooms.

3. Climate Suitability

  • Heat pumps work best in warmer climates, but some models are designed for colder regions.

4. Energy Star Rating & Efficiency

  • Look for high efficiency ratings to maximise savings.

5. Installation Requirements

  • Ensure enough outdoor space with proper ventilation.
