Choosing between a hot water heat pump and a gas hot water system is a frequent dilemma for New Zealand homeowners to face. Both have different pros and cons, but understanding their differences is sure to help you make the right decision for your home, your wallet – and the environment.

A2W Plumbing explains all in this article.

Gas water heating

We begin with gas water heating as one of the traditional methods of heating water for a NZ home.There are many pros and cons to gas water heating, and in a rapidly-evolving world where climate change is a tangible threat and gas supply is uncertain, it’s unfortunate to admit that this once-popular solution to hot water heating is no longer as economical or desirable as it once was. Read on for more.

The pros

1. A Continuous Supply of Hot Water, Never run out of hot water
2. Lower Upfront Installation Cost
3. Lower running costs than a traditional, resistance hot water cylinder

The cons

1. No stored hot water so no hot water available during a power cut
2. Monthly line charge or bottle rental for gas can be higher than your actual gas usage charges
3. Burning Gas or LPG Produces Damaging Carbon Emissions

Hot water heat pumps – and why you should choose them

Hot water heat pumps, otherwise known as air to water (A2W) heat pumps, also come with their own advantages and disadvantages. However, it can’t be denied that their advantages far outweigh the traditional benefits of gas hot water heating!  Read on for more.

The pros

1. Extremely Energy-Efficient – Up to 70% Less Energy Used Than a Gas System
2. Fewer Greenhouse Gas Emissions Produced
3. Installed outside, so don’t take up valuable space in the home

The cons

1. Higher Initial Installation Cost – most banks now offer a very low finance “green loan” to help with upfront costs
2. Less Effective in Very Cold Regions – Which Doesn’t Apply to New Zealand!

Ultimately, you should choose a hot water heat pump for its energy efficiency, long-term environmental benefits, and the impressive cost savings that you will accumulate over time. Saving money and the environment is an undeniable advantage that gas hot water heating simply can’t compare to.
