Hot Water Upgrade

Hot water heat pumps offer a smarter, more energy-efficient way to heat water while significantly reducing your electricity bills. Instead of generating heat like traditional systems, they absorb heat from the surrounding airβ€”delivering powerful performance using far less energy. This means lower running costs, long-term savings, and a greener hot water solution for your home.

With government rebates available under the VEU program, you can upgrade to a high-efficiency hot water heat pump at a heavily reduced costβ€”making it one of the most affordable and rewarding home upgrades today.

Whether you want lower bills or a greener lifestyle, Greentastic’s solar panels and batteries deliver dependable performance, long-term savings, and sustainable energy for every season.

I recently had a new hot water system installed by Greentastic Pty Ltd. as it stopped working just like that.Thanks to Manish for arranging its installation as urgent next day and I couldn't be happier with the experience. From the initial consultation to the final cleanup, the entire process was seamless and professional.The customer service throughout the entire process was outstanding. Thanks to Sumi for helping in documentation and processing application. I will recommend company services to my friendsThanks once again

I would like to caution anyone approaching this company. Over the span of two weeks from when I was first contacted by them while looking for an AC system, they have been incredibly pushy pressuring me to take on their service. They called me everyday despite me advising that I was busy with work and I need time to look through product reviews, decide which units to install etc. Ravi (Sales Manager) did not relent with the calls, voicemails and emails telling me to "hurry up". He also pushed for only one brand "Midea Apollo series" which is not a familiar brand to me (thus requiring me time to do my due diligence). They did not provide other brands Mitsubishi, Fujitsu etc. When I advised him I was not proceeding further, he hung up on me straightaway leaving me incredibly shocked and disrespected, considering the boundaries I felt he crossed with his relentless calls. While I can't speak for their installation service, I have never countered this type of boundary-pushing customer service before, and would like to warn others of what they may encounter.

I recently used Greentastic for my heating and cooling needs, and I’m extremely satisfied with their service. They took the time to understand my specific requirements and recommended the Carrier 17kW reverse cycle system with AirTouch 5. Thanks to this system, I can now control 8 different zones individually, which helps me save on energy costs.A special mention goes to Ravi, who was outstanding throughout the process. He quickly adjusted quotes based on my changing needs, which helped me make an informed decision without any hassle.While there was a slight delay with the old ducts being left on my lawn for a couple of days, they were promptly collected by the cleaning service afterward. This small issue aside, the overall service was excellent, and I’m very happy with how everything turned out. I highly recommend Greentastic for anyone looking for heating and cooling solutions.

From the beginning,the services was impeccable ,they really care about what actually i want not just pushing to sale something that I dont need. The installation was scheduled as early as a week after the sales being agreed. The installation it self was smooth and fast. Really recommended place to buy your airconditioning.. Thanks Greentastic, and thanks to Saiful and Manish for their assistance. Cheers

We had an emerald 270 electric hot water pump installed. Greentastic were great to deal with. They were cost effective with straight forward pricing upfront and excellent communication. The installers were excellent and went above and beyond, to make sure all was ok.The time frame from initial inquiry to installation was extremely quick. Would highly recommend Greentastic.

I had five air-conditioning heads installed, initially they gave me four remotes and then rectifed their mistake by hand delivering a fifth remote. They even took the rubbish away which doesn’t happen very often with other companies.I couldn’t recommend them highly enough for service and quality of product so far.

Since having my new heat pump installed, I've been very impressed. It keeps my home comfortably cool in the summer and nice and warm in the winter. The best part? My energy bills have noticeably decreased thanks to the heat pump's efficiency.
