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!

We have just enjoyed a hassle free process of changing over from a heat pump that has served us well for almost twelve years to a new one supplied and installed by GM Hot Water Beginning with a prompt quote and other useful information from Natika in the office to the installation by the Plumbers and Electricians we can say without hesitation that thus far it has been a job well done. So keep up that good work.

We have just had a new Rinnai solar hot water system installed by GM Hotwater. Our experience has been excellent right from working out what system we needed to the installation and paying for it. The trades being Plumbers and Electricians were very efficient and tidy throughout the install. Great to converse with and worked right through lunch in order to get the job done. I can definitely recommend this company if your considering a hot water system. Lyndon

Very prompt service and straight to the point supplying a great offer not worthy of shopping around for a better deal! Natika updated myself on weekends and before business hours proving to go above for the customer. The two lads who fitted our HWS were great service men and although having a big job late in the day to complete, they happily removed all our old solar and tanks to make the end product just that little better removing an eye sore we had on the front of our roof!

Brilliant work. Service was super fast- barely a few hours after calling and my new system was up and running. Staff were also fantastic- very friendly and went out of their way to explain what they were doing and why. Can't rate them highly enough. Will absolutely call again if I even run into any issues 🍻

It's a pleasure dealing with GM Hot water from A to Z. The quotes were done efficiently and professionally. Within minutes the options were emailed and clearly explained. The service was second to none. A plumber was at my doorstep early next morning and the job was done timely. His pleasant personality and workmanship were admirable.

They came out and replaced my water heater just a few hours after I phone then. The insulation was fast and neat, he also replaced all the old exposed copper and installed two new taps. I would definitely recommend them. the insulation cost was $750 cheaper than another quote I had received, so always do your own research and get three quotes minimum.

From my first enquiry on a new hot water service to installation the service was outstanding. Unsure initially of the right size for my needs, Natika provided me the relevant information and reccomendation which helped make a decision. The installer Aaron was friendly and very efficient. He advised me at key points during the installation process.I was very appreciative of his understanding of the process. Price was fine by me. I felt it was value for money. I cannot praise the team enough. THANK YOU!!!

Everyone I have been in contact with from the company has been excellent to deal with. The plumbers were punctual, polite, clean and did a fantastic job. Prices were reasonable for the job and I didn’t feel like I was being taken advantage of or ‘ripped off’. I will definitely use them again.

Natika was so helpful with advising us on costs and the different types of Gas HWS available. She had us booked in the next day and Mark advised and quoted us on the job. Bradley and Sam did a great job, very professional and neat job done in such hot weather. It was a pleasure dealing with your company from start to. Glad we used a local company. 😊

Having received a quote from elsewhere, I was SHARPE enough to check around and HOTWATER quoted 55% less (on a final invoice of $1,200 you can work out how high the original quote was!). Very impressed with the whole process and competitive price. Aaron was friendly, thorough and explained everything as he went along. Nitika also followed up the next day, leaving a very detailed message. You're never quite sure when you pick a company cold from the Google search, but these guys were great.
