Gas Water Heaters

Featuring the best gas water heaters in New Zealand

Simply put, gas hot water heaters are used to heat water by pumping the circulating water through pipework across a series of flames. There are several different types to suit the needs of any home or business, which include tankless, storage, condensing, combination (combi), direct vent, and power vent gas water heaters. Only the best gas hot water heaters in New Zealand are featured on ArchiPro, an important part of a broader range of hot water heating solutions you can consider for your home.

Types of gas water heaters

Tankless (on-demand) gas water heaters

Tankless heaters heat water directly without needing a storage tank, providing hot water only when needed.

Storage (tank) water heaters 

Storage water heaters feature a large insulated tank that stores hot water for use when needed.

Condensing gas water heater 

Condensing heaters capture heat from exhaust gases and use it to heat the water, improving efficiency.

Combination (combi) gas water heaters

Combination heaters provide both space heating and hot water from a single unit.

Direct vent gas water heaters

Direct vent heaters use a vent pipe to bring in air from outside for combustion and exhaust gases back outside.

Power vent gas water heaters

Power vent heaters use a fan or blower to exhaust gases, allowing for more flexible placement.

Advantages of gas water heaters

Gas water heaters offer several advantages, making them a popular choice for both residential and commercial use. They are highly efficient, quickly heating water and providing a continuous supply, which is ideal for households with high hot water demand. Additionally, gas water heaters are cost-effective, often resulting in lower energy bills compared to electric models. They operate independently of electricity, ensuring a reliable hot water supply during power outages. Modern models also feature advanced safety mechanisms and are designed to be environmentally friendly by producing fewer emissions.

How to choose a gas water heater

Choosing the right gas water heater involves evaluating your household's hot water needs, considering the type of heater (tankless, storage, condensing, or combination), and checking efficiency ratings like the Energy Efficiency Certificate (EEC). Decide between natural gas or propane based on availability and cost. Consider the unit's flow rate or tank capacity, and ensure proper venting and installation space. Review maintenance requirements and warranty options, and balance initial costs with long-term savings. Finally, look for any available rebates or incentives to reduce overall costs.

Ongoing maintenance

Spending a little more on gas water heaters can save a lot of money in the long run, providing peace of mind. A one-time service costs slightly less than an electric one, and some home insurance companies offer failure coverage as a primary or optional feature. Adding breakdown coverage to an insurance policy is sometimes less expensive than buying a breakdown contract, though the benefits may differ.

Other heating and cooling solutions to consider

There are more than just gas water heaters to consider as a solution for your home. For instance, you could take an environmentally friendly approach and install a solar hot water heater, which has the added benefit of lower energy bills. However, if you are looking for something with easy installation that generates instant heat, you could use an electric water heater. If you prefer something with a tenured history of reliability and minimal repairs, a boiler is the perfect choice.
