Heat Pump Hot Water Pros and Cons

Advantages

• Significantly lower electricity use for the same hot water
• Works with the way your household already uses hot water
• Well suited to replacing ageing electric cylinders
• Supports moving away from bottled or reticulated gas
• Available as integrated or split configurations
• Contributes to lower household energy consumption

Drawbacks and considerations

• Higher up-front installation cost
• Requires suitable outdoor space and airflow
• Produces fan and compressor noise during operation
• Efficiency drops in colder ambient conditions
• More components than a simple cylinder, so servicing matters
• Not always practical in apartments or tight sites

Who should think carefully

If your hot-water usage is very low, if the only viable outdoor location is close to a bedroom window or boundary, or if you are planning to sell in the short term, the economics and practicalities may favour a conventional cylinder.

A site assessment by a qualified installer is the only reliable way to answer this for your property.
