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.

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.

LATEST REVIEWS
Great experience dealing with hotwater.com.au, I had several questions about how the transition would work to disconnect our existing gas and install an Istore heat-pump to run off our PV system and all the staff were extremely helpful.Even though it took me awhile to finally commit they were able to redo my old quote quickly when I did decide to go ahead.Quote was extremely competitive and everything was clearly written / explained. The 12 months interest free Zip option was also a nice touch.It’s been a few weeks since install and everything has been working perfectly, I look forward to seeing the savings and knowing that I am having a positive impact on the environment at the same time.
Response from the owner: Thank you so much for sharing! We're thrilled to hear that you had a such a great experience with us. It was a pleasure to help and we hope you have a fantastic week 😊
Very helpfull man on the phone. Happy with quote and installation.
Response from the owner: Thank you Lyn, I'll be sure to Let Pat know 😊 we appreciate you taking the time to leave us a review, have a wonderful rest of the week.
We are very happy with the unit. Liam and his offsider (sorry name escapes me) were friendly and did the job in a professional manner. They cleaned up well and explained the workings of the heater
Response from the owner: Thank you for your review, that's great to hear! I'll be sure to pass this onto Liam & Braeden 😊 have a lovely rest of the week.
Supply and installation of new gas hot water system was all done in 24 hrs from initial inspection on old faulty appliance. Excellent service.
Response from the owner: Thank you Ken for leaving us a review, it's great to hear and we really appreciate it 😊
The technicians arrived on time. They asked if I wanted them to remove their boots before walking on the carpet. They worked steadily and efficiently. Due to the age of the heater they advised me to purchase a Co Meter. I have followed this advice ! I am very happy with the service given !
Response from the owner: Thank you so much Bev, that's excellent to hear! I'll be sure to pass this onto the team 😊 have a wonderful week!
Customer service second to none. Decided to buy a heat pump and landed in the best possible position for this costly purchase, starting with hotwater.com.au's informative website. Purchase and installation (thanks, Mark and Liam) were so easy and professional. All necessary documentation followed from Natika in the office, an absolute gem. When hot water failed on a Saturday night due to an idiosyncracy in weekend timing for this model, Natika answered our cry on Sunday morning and, although I managed to get hot water back on, by Monday Liam was dispatched to check out the system. Total confidence this end. Thanks, hotwater.com.au!
Response from the owner: Thank you so much for the lovely review Pamela, it was our absolute pleasure to help. It's so great to hear and an amazing start to the week. Apologies again about the weekend timer. Have a lovely, warm and dry rest of the week 😊
Thanks so much for your wonderful service. The guys went over and above to help fit my new instant gas hot water system. Hotwater.com.au already saved me nearly $2000.00 for the same job quoted by others and then went out of their way to save me more by working out a way to fit the unit into the available space. I am so grateful guys.Recommended highly!!!
Response from the owner: Thank you Glenys for the lovely review, that's wonderful to hear and I'm glad we could help 😊I'll be sure to pass on your kind words to the team. We really appreciate it, have a great rest of the week!

The first thing I would like to say is to commend HOTWATER.COM.AU for installing the iStore heat pump hot water system very efficiently and professionally at my home on 9 May 2024. The two plumbers undertook the installation with minimum interference to our normal activities, and left the house with little evidence that they had been present for just over 2 hours, except for a spanking new hot water system located outside the house. The electrician came after the plumbers had left but spent a bit more time than the installers inside and outside the house and above the ceiling. He did a great job wiring up the hot water system and reorganising the primary and secondary switch boards. The plumbers and electrician were extremely respectful and considerate of other people, and took away all unwanted materials, including the entire old solar hot water system from the roof. They left my house with the guarantee that the equipment would work perfectly, and so far the system has not missed a beat. We are getting a good supply of hot water when required and are extremely pleased to have chosen hotwater.com.au to be the supplier and installer. We received two Government rebates which was a bonus indeed. The staff at the office were easy to communicate with and ensured that the installation went smoothly. All in all, the changeover of the hot water system at my home was quite painless, thanks to the highly trained technicians who carried out their assignments with care and dedication.
Response from the owner: Thank you so much Andrew for the fantastic review!!! We appreciate you taking the time to write such a glowing & extensive review. I'm so glad to hear everything went smoothly with the installation and still continues to be with the units operation. The iStore has definitely been a fan favourite. Thank you again for the kind words, we hope you have a wonderful rest of the week! 🥰 it's been a plesure
Called for a quote for 270L heat pump. Not only were they the cheapest, but Hotwater.com.au were able to install the next day. Very professional and would recommend to anyone.
Response from the owner: Thank you so much for your review Wes, have a wonderful week! 😊
Good service easy company to deal with. Fast and efficient installation. Highly recommend
Response from the owner: Thank you very much Amanda, that's fantastic to hear and a great end to the week 😊. We really appreciate it, we hope you have a wonderful weekend!
A very pleasant experience from start to finish. Minimum 4 phone calls and 3 emails for promptly supplied information and quote. Installation was provided in a professional pleasant manner on time and at a lower cost than quoted despite a last minute positional request from me.Old unit removed from roof and disposed of..Well done to entire TEAM much appreciated.Andy
Response from the owner: Thank you so much Andrew, that's wonderful to hear! I'll be sure to pass this on to the crew 😊 thank you again for providing such a glowing review, we really appreciate it.
Absolutely excellent service. After receiving over the top quotes from 2 other companies called hotwater.com.au. No call out fee, I was given a quote over the phone, literally thousands cheaper! Hot water unit was installed the next day. The plumber they sent was on time, very good to deal with and professional. Even though the installation took longer than expected there was no extra charge. I can’t recommend this company highly enough. Quality service with affordability are a rare thing these days, hotwater.com.au gives both. Well done
Response from the owner: Amazing! 🥰 Thank you so much Tony for leaving such a glowing review, we really appreciate it! Have an excellent weekend

We had iStore 180 installed one week ago, Hotwater.com.au did everything they promised. Happy with the price, product and service.
Response from the owner: Thank you Trevor, that’s fantastic to hear! Glad everything went smoothly 😊
Had a Reclaim Heat Pump installed by Hotwater.com.au in February. Brilliant experience from start to end. From initial contact with Natika with very competitive quote she had installation fitted into our tight schedule. The communication by her was second to none. The installation team were great and fitment was perfect. The Reclaim Management team from interstate were also very impressive. The System is so quiet and hotwater supply is better than ever and so inexpensive to run, but expected from the top of the range system. After a very disappointing dealing with another 'Adelaide Heat Pump' company over 4 1/2 months it was so refreshing to deal with Hotwater.co.au . Totally RecommendThankyou Natika and team.Cheers Morgan and Kerry
Response from the owner: Thank you so much for your kind words, Morgan and Kerry! We're thrilled to hear about your positive experience with our team. Your recommendation means a lot to us, and we're grateful for the opportunity to help. Cheers to many years of reliable hot water supply!
Helpful staff that are clued up on rebates/schemes to get some money back. I found the heat pump installation smooth, 180lt good size for 3 people, even with long showers and hot water is quicker than instantaneous hot water. It is more expensive initially, but should pay for itself in gas savings.
Response from the owner: Thank you so much Malcolm, we love to hear it! We really appreciate you leaving us such a detailed & wonderful review. Have a great rest of the week 😊
Friendly professional staff, excellent service. Much appreciated.
