GAS HOT WATER SYSTEMS
ABOUT GAS HOT WATER
Gas hot water systems burn gas to heat water which generates far fewer greenhouse gases than using electricity from the grid. Gas systems can come in either a gas storage water heater, or a continuous flow/instantaneous water heater.
Gas storage hot water systems will usually have a continuously burning pilot flame which ignites a burner to heat the water in the tank when it is required. Usually the unit will have a thermostat which tells the system to heat the water in the tank if it drops below a specified temperature.
A continuous flow or instantaneous gas hot water system doesn’t have a storage tank as it simply heats the water via a gas burner which is activated when a hot water tap is turned on in the house. It only heats the amount of water that is required instead of continuously heating a full tank which means they can have large energy and cost savings. More importantly, what this means for the consumer is that with a continuous flow system you will never run out of hot water.

PROS AND CONS
OUR RECOMMENDATIONS
If you’re looking at upgrading your current gas system or connecting for the first time, we recommend installing gas continuous flow. With higher system warranties, 6 star+ energy rating & optional temperature control, this style system can suit the largest or smallest of families, only heating the water that you use.
Love a long shower? Never do you have to worry about running out or fluctuations in temperature as the water is heated as it flows through the system.
Temperature control provides safety & comfort to those with young kids and also saves on water & gas usage. Set your controller anywhere from 37 up to 50 degrees without the need of turning on a cold tap.

From the very first conversation on the phone under trying circumstances, Natika talked me through the process of replacing my hot water service and gave me excellent information to get the best possible result with great pricing to match. Natika’s customer service was brilliant and I have no hesitation in recommending this company. Bradley the plumber turned up early to get the job done and when we had to change the initial plan he came up with a great solution which gave me a much better result. Bradley was personable and very knowledgeable about his craft. Very happy customer wth the service, price and quality of work carried out !Definitely will use these guys again.5 starts for sure!

Really impressive service from the first phone call to the last set of paperwork. Efficient, quick and a great job. Felt totally comfortable with every aspect. I appreciated their advice and they welcomed my shopping around to compare price and service standards. Gave me confidence in their quality and they didn’t disappoint. On-site the guys were great, explained what they were doing and why and got on with the job. Same day service, great pricing and a terrific result. Totally recommend them.

Our experience with GM Hotwater was excellent. My wife sent an email through the website and I got a phone call within around an hour. The young lady on the phone, Natika, was a gem. She has a bright and bubbly personality as well as being very knowledgeable in regards to hot water systems. She answered all of my questions and also informed me of a few things that I did not know. She arranged to get a plumber out promptly and my hot water service was repaired. The young lad that did the repairs was polite, efficient and did the job quickly. Again when I spoke to Natika the following day to pay my account there was more of that vibrant personality again. A pleasure to deal with and I would be more than happy to recommend them....Jeff

Initially spoke with Andrew after existing HWS died. He was very helpful in assisting us to make a decision on a replacement and made arrangements promptly. Then had excellent follow up from Nitika with a quote and answers to a few more questions. Sam arrived earlier than scheduled to do the installation and was professional and friendly.Overall turnaround to get hot water running again was really quick which was greatly appreciated on a cold winters day

We had just moved in to our newly bought house and found that the hot water service was leaking. Made a call to GM Hotwater and the gorgeous lady helped me with my queries and booked us in for a quote/repair/replacement. Ryan arrived on time, was super friendly and he was so helpful. We ended up replacing the unit after our discussions with him. He had great knowledge on the Rinnai products and what we needed. He tided up a few bits and pieces from the previous installer (without asking as he was concerned about some of the fittings) and I would recommend him a thousand times. Great Job Ryan!
