Why Go Gas?

Energy Efficiency

First and foremost, one of the most compelling reasons to choose a gas water heater in New Zealand is its efficiency. Gas water heaters, whether they are natural gas or LPG, tend to heat water much faster than electric hot water cylinders.

For a household with a high demand for hot water, especially during New Zealand’s colder months, this can be a major advantage, ensuring you always have not water when you need it.

Additionally, even in the event of a power outage, most gas water heaters will continue to operate, ensuring that you have access to hot water at all times (unlike with electric hot water cylinders).

Cost Effectiveness

Another reason to opt for a gas water heater is the cost-effectiveness. Although the upfront cost of a gas heater may be a bit higher than an electric hot water cylinder, the operating costs are often significantly lower.

This is because LPG and natural gas are generally cheaper than electricity in New Zealand, especially given the rising electricity costs in recent years. Over the lifetime of the water heater, this cost difference will often result in considerable savings, making gas water heaters a very good economical investment for the long term.

Environmentally Friendly

Lastly, when compared to coal-generated electricity, natural gas is a cleaner-burning fossil fuel, producing less harmful emissions and reducing the environmental impact.

To add to that, advancements in technology have led to the development of condensing gas water heaters, which are even more efficient and environmentally friendly. For those concerned about their carbon footprint, a gas water heater is a step in the right direction.

How to Chose the Right Gas Water Heater for Your Home

If you are looking to upgrade to a gas heater or install a new gas heater on your property, here are some things you need to consider.

  1. Size of the Water Heater

    Firstly, you need to consider the size of the gas water heater, which is determined by your household’s hot water needs.

    This is typically calculated using the ‘First Hour Rating’ (FHR) which estimates how much hot water the heater can provide in the first hour of usage. For instance, a family of four will typically require an FHR of approximately 340-380 liters. However, this could vary depending on individual lifestyles and peak water usage times.

  2. Energy Efficiency

    Secondly, consider the energy efficiency of the unit. Energy Factor (EF) is a measure that indicates the energy efficiency of a water heater. The higher the EF, the more efficient the heater is.

    More efficient heaters may cost more upfront but will save money in the long run due to reduced operating costs. Look for models with a high EF rating and those certified with an Energy Star, indicating that the model meets or exceeds energy efficiency standards.

  3. Type of Gas Water Heater

    Finally, consider the type of gas water heater. There are two main types: tankless and storage tank heaters.

    Tankless (instantaneous) heaters heat water directly without the use of a storage tank and are more energy-efficient since they eliminate the standby heat losses that come with storage water heaters. They also take up next to no room since they are only a small unit. However, they provide a limited flow of hot water per minute, which may not keep up with your demands.

    On the other hand, storage tank heaters have a ready reservoir of hot water and can serve multiple outlets at once, but may consume more energy due to standby heat loss which requires them to heat the water more. They also take up more room, since you need to install the storage cylinder somewhere which is often quite large.

Remember to also take into account the cost of installation and maintenance, as well as the product warranty. You will also want to consider factors such as the availability of natural gas or LPG in your area and the design of your home.

My first experience with complex was great from the very start, very good and upfront communication, a key trait I respected was they always did what they said they would at the time they said they would, and communicated well along the way, and also provided guidance around “why” for some things which helped in decision making. The whole team is super professional, the workmanship was standout, they don’t take short cuts, and the team were very polite and so clean, taking shoes off in the house and really cleaning up after themselves. It’s really these little things that make a big difference in my view. Every job since then I’ve had the same experience and would easily refer these guys to friends and family. I deal with Nathan the most, but the whole team has been great in my interactions with them also. Highly recommend

I enlisted Complex plumbing to do a couple of jobs on a rental property. They were great communicators and made sure that they were completing the job exactly how I wanted. They suggested a range of taps that would be suited to the fit out and gave information on what they thought was best suited to the job. As I am really busy this helped me out a lot. The job was completed promptly and I was really pleased with the end result. I have already referred them to other friends.

We enlisted Complex Plumbing to work on both our Bathroom & Kitchen major Renovations and we really couldn’t be happier! Jason & his team were great to deal with and kept us in the loop from the outset. The pricing was very competitive and Jason made sure to guide us through the entire process by giving us a range of different price points & options. The team was clean and tidy when working . Really very very happy. We have already recommended their services to our family & friends and will definitely use them for any future jobs/projects! Thanks again Jason!

I contacted Jason to come do some plumbing work during our renovation, moving our entire water system and kitchen fit out. Him and his team were extremely reliable, professional and diligent. Work was immaculate - couldn’t recommend any higher. I would give him 10 stars if possible!

I happened to see Jason's phone number on the van at our street. So I had no hesitation calling Jason when I discovered a leak from my laundry tub. Just ONE minute after my phone call with Jason, the plumber is at my house!! How efficient and responsive! The plumber spent his precious time here investigating the leak in the middle of his busy project! Really appreciated! Out of all, there was no charge for the work! The plumber was in a hurry to his scheduled work and had to return another day to repair, but my husband figured out to repair the leak at the last. We definitely recommend Complex Plumbing! Thanks a lot Jason.
