Nowadays, hot water heat pumps are often termed ‘the most efficient water heater’ possible for New Zealand homes. But, this moniker doesn’t answer the question of how energy efficient they are. This is where we at A2W Plumbing and Heating feature! Our blog post answers every question you may have about the efficiency of a hot water heat pump– read below to find out more.

A hot water heat pump uses around 60-75% less electricity than traditional electric hot water systems

It’s true that a hot water heat pump – because it uses electricity to extract heat from the air, qualifying it as a renewable energy system – ultimately utilises around 60-75% less electricity in operation than a traditional electric hot water system.

Similarly, it also uses around a third of the energy needed by gas water heating!

A hot water heat pump provides substantial cost savings because it is renewable

If we take into consideration the purchase, installation and energy costs of a hot water heat pump, New Zealand homeowners can save up to $5,090 over a 15 year period compared to an LPG gas system, which increases to $6,760 over 15 years if compared to piped gas water heating. This is because you rely on a lesser amount of electricity from the grid, and you’re not spending on gas cylinders that are also prone to leaking! If you live in an area with higher electricity costs, or your house has solar panels installed, your savings will be even greater – testifying to the great energy efficiency of a hot water pump heater.

Hot water pump heaters generate lower emissions

Very little carbon dioxide is emitted to power hot water pump heaters, particularly because they operate from New Zealand’s renewable electricity grid! They save around 7,000kg of emissions throughout a 15-year period as opposed to gas or LPG water heater systems, which were the conventional and popular option for New Zealand households in the past.
