I highly recommend this organisation. I bought a heat pump water heater to replace gas instant. The whole process took about maybe 2 weeks from first enquiry to installation - amazingly fast! They were very responsive to questions, I was given good advice about available systems (the one I originally wanted was not available), it was a competitive quote and they organised all the rebates so I didnt have to work it out for myself. Thanks very much for all your help.

I am pretty happy with the service of HOT WATER COM AU. From quoting to installation, easy, professional and quick for each step. They don’t charge for quoting and be honest with government rebate that has exhausted at the end of year. Comparing to the other company that I also contacted which charge for quoting and hide the fact that two rebates are available but one exhausted. Change from gas to heat pump water system is much easier than I thought when I chose HOT WATER COM AU to do it for me and price is pretty good as well. Highly recommended!

This business is exceptionally helpful, honest,polite and friendly.
They are always ready to help even when we had an initial issue with the Hot water heater.
This was definitely NOT their fault but they helped us solve the issue anyway.
Their communication and replies to questions are superb .
Any business is happy to take your money but the quality of the business is what they do when there is an issue and this is the gold standard for customer service.
This business passes that test with flying colours and I could not recommend them more highly.
Emphatically recommend.

Great experience with Hotwater.com
From the very start of my enquiry, with Natika, who not only answered questions about Thermann x Split Heat Pump unit, but supplied additional info as well, right through to the installation, which was carried out smoothly, was excellent.
The unit has been installed now for over a week and has proved to be great, using solar power to heat our water supply. Can’t recommend the unit more and also the work carried out by Hotwater.com. Thanks a heap guys.

Hot water unit broke down and Ray white called a plumber. Purity plumbing and gas comes over and provides a quote for $1,800.00 to fix and install.
As I was at work and had no time to sort this out I decided to proceed. Thankfully, it was close of business and installation was to be done the following day.
When I went home, I searched online and came across these guys in a facebook ad. Called them early in the morning, spoke to Nitika and could not believe the quote of $1,295.00 supplied and installed SAME DAY, EXACT SAME RINNAI B20 MODEL! Absolutely no dramas, no call out fees, nothing! These guys saved me $500.00. I wish all plumbers were like this open and upfront quotes, no bull shit. Unluckily for me, Purity plumbing and Gas proceeded to charge me $165.00 for call out and quote. Thanks to these guys, I still saved $335.00 🙏🙌❤️

Thank you Patrick & Sam.
Patrick and Sam did an absolutely fantastic job replacing my old hot water system with a brand-new one. From start to finish, they were professional, efficient, and incredibly knowledgeable. They arrived on time, explained everything clearly, and worked diligently to ensure the installation was done to the highest standard.

Not only did they complete the job quickly, but they also left everything clean and tidy, which I really appreciated. Their friendly attitude and attention to detail made the whole process smooth and stress-free.

If you’re looking for reliable and skilled professionals, I highly recommend Patrick and Sam. Thanks again for the excellent work!
Cheers, Greg

We have had a heat pump water heater installed today. The quote (initial recommendation via Solar Quotes website) was provided promptly, as well as further answers to questions, including options and prices. The installation was done professionally, thanks to Cory and Braeden, and the unit is working fine. No reservations in dealing with Hotwater.com.au at all.
