How Does a Heat Pump Hot Water Cylinder Work?
Unlike a traditional electric hot water cylinder, a heat pump doesn’t rely primarily on an electric element to generate heat. Instead, it extracts warmth from the surrounding air and transfers that heat into the water stored in the cylinder.
Think of it like a refrigerator working in reverse. A fridge removes heat from inside and releases it into the room; a heat pump hot water system captures heat from the outside air and uses it to heat your water.
Because the system moves heat rather than creating it directly, it can heat the same amount of water using considerably less electricity than a conventional electric cylinder.
Most systems also include a backup electric element. This can provide additional heating during periods of unusually high hot water demand or when required in colder conditions, helping ensure reliable hot water throughout the year.
How Much Can You Save?
For many households, hot water heating is one of the largest contributors to power bills. Heat pump hot water systems can significantly reduce the amount of electricity required to heat water compared with traditional electric cylinders.
Estimated Energy Savings
| System Type | Typical Efficiency |
|---|---|
| Standard electric cylinder | Higher electricity usage |
| Heat pump hot water system | Can use around 60–75% less electricity |
Actual savings vary depending on:
- Household size
- Hot water usage
- Shower and bath habits
- Power prices
- Cylinder size
- Existing system efficiency
Households with higher hot water usage often see the greatest long-term savings.
What Size Heat Pump Hot Water System Do You Need?
Choosing the right size system depends on:
- Number of people in the household
- Number of bathrooms
- Shower and bath usage
- Peak hot water demand
- Future family growth
General Household Guide
| Household Size | Typical Cylinder Size |
|---|---|
| 1–2 people | 180L–210L |
| 2–4 people | 250L–300L |
| 4–6 people | 300L+ |
| Large families or high usage | 300L–400L+ |
Homes with multiple bathrooms, teenagers, large baths, or high hot water usage may require a larger system.
