HEAT PUMP HOT WATER SYSTEMS
ABOUT HEAT PUMP HOT WATER SYSTEMS
Heat pump hot water systems work similarly to that of an air conditioner, by taking hot air from its surroundings, and using that to heat water. They operate on electricity, but as they use a refrigerant gas to heat the water and not the electricity directly they are quite a bit more energy efficient than electric hot water systems.
However, for South Australian consumers this may not directly translate to financial savings. Due to their reduced electricity usage & reliance on the temperature, most manufacturers will only connect a heat pump hot water system to your general use electricity tariff instead of the cheaper controlled load tariff that a standard electric hot water system would be connected to. This generally means the savings are minimal, or sometimes you will even be paying more. A lot of information you find online regarding savings are based on QLD or NSW tariffs which are cheaper for day use.

PROS AND CONS
OUR RECOMMENDATIONS
Heat pump solar hot water systems are an efficient technology which in some very specific situations can save money and energy, however in South Australia our lack of time of use electricity tariffs and cooler climate overnight mean that consumers end up running the system for longer hours at a more expensive cost. Additionally, heat pump systems generally come with the lowest warranties on the market so the overall lifetime of your system is likely to be shorter.
We have found that South Australian consumers generally end up spending more on electricity and maintenance of heat pump systems than a comparable sized solar or gas system, and as such generally do not recommend them for South Australian homes.

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.

These guys are really good and very professional. The customer service from Natika was a breeze, the quote was very fair and detailed and they did what they said they would with no surprise cost. Ryan the plumber was really great, prompt, polite, friendly, well presented and on time. He did an awesome job too. The Electricians that came to install my powerpoint were very nice too.I definitely recommend GM Hotwater and would use them again in the future should the need arise.

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!

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 thePlumbers and Electricians we can say without hesitation that thus far it has been a job well done. So keep up that good work.
