Our large family house had a Quantum Heat Pump HWS for over 16 years and it served our family of 4 well. Sadly the tank started leaking and we looked to buy another Quantum heater.
Frankly it lasted so long as I changed the anode every 5 years or so, tested the relief valves and installed a water filter unit to keep sediment down, its amazing how dirty they get.
I contacted Joe and he suggested the 250L Sanden Unit. (I later opted for the larger 350 Litre unit).
Quantum are now built in China and after reading a number of reviews not ma...ny people seemed happy with them anymore. The Sanden isn't the cheapest option but given I'm expecting it too be a 15 year investment I took the long view that it will pay for itself in time. Joes guy arrived as promised, he was an interesting character in himself.

We've had problems with our Sanden heat pump since we got it back at the end of 2015. It started with corrosion of the external covering of the tank and around the water inlets/outlets meaning constant leakage. We've had to replace the thermostat within the first year as we were getting no hot water. And for the last few months for some reason it has been switching off so every time we want a hot shower we have to remember to go out and turn the power off for a minute then restart it to crank it up again an hour before we shower! I'm not happy and living 2.5 hours from Perth, no-one seems to want to come out and help us sort it out. Great when it works, but too many issues.
Oregan Air Conditioning North West Sydney what a great installation!
A year ago when the service technitian representing Rheem told me my Rheem Heat Pumps compressor was gone and I should replace it I was unhappy. It had been troublesome since it was installed in 2009. I decided to check out Sanden after reading their reviews and Greg from Oregan Air Cond came by to quote me. He was honest and reliable and fixed the Rheem unit in 5 minutes and left without charging me. He could have easily said the Rheem was kaput and quoted me for a Sanden.
Fast forward 12 months and the Rheem finally gives up the ghost. I w...ent back to Greg and got a Sanden this time. For an extra $500 more than the Rheem they are twice as good. They only use 4 watts that's half the power the Rheem unit uses. That's because the heat exchanger used CO2 and has a bigger surface area than the compromised Rheem unit where all that stuff is housed on top of the water tank. The Sanden unit is far superior in my opinion and the separate compressor means a much less complex design that can be more easily serviced. I'm highly impressed with the product and Greg and his lads were great installers and took a great deal of care to have the install looking neat and included extras like an isolation switch at the unit itself.

Wonderful until it breaks down
Not at all happy with my Sanden heat pump. $5000 and three years later it has died and I now learn that it only had 3 years warranty. How can this possibly be described as an economic and efficient system?
No word on whether it can even be repaired. If I have to replace it, I certainly won't be investing in another Sanden.
Thanks Australian Hotwater Cardiff
Thanks to Chris at Australian Hotwater Cardiff NSW for a swift next day install of our new Sanden 315 litre heat pump hotwater system. I can't believe how quickly Chris mobilised his team to get a family of 8 out of cold water (Bosch 16H LPG system failed) and into a system that is supposed to be the best on the market so quickly and without fuss. Zane our installation technician did a great job, working alone to get us piping hot water in less than 6 hours considering it was a major system upgrade and long pipe run. Thanks Zane for a neat and...tidy job. Also Zane had to drive to Bulahdelah through peak hour traffic and arrived with a can do attitude - not to mention it was freezing cold winters day. I hope to be able to give an update on the Sanden 315 system within a couple of months. So far I consider it to be ultra quite, unobtrusive (I got a 315 litre short tank) and provides piping hot water (better than the Bosch 16H piece of scrap metal) From my research the Sanden system is the best on the market. I will update my review in 6 months.

Sanden Heat Pump hot water system super quiet!
We have just had a Sanden 315L heat pump installed by Pathfinder Plumbing in Brisbane. It's early days, but so far so good, the system is very quiet, and we certainly have plenty of hot water :) Phil Gilliland of Pathfinder did a great job of the install, very tidy and professional work, he obviously takes pride in what he does! Turned up on time, got the job done, cleaned up afterwards, I would thoroughly recommend him if you are after one of these systems. Phil had the system installed before some places I had asked for a quote had even come back to me!!!
We had a Sanden Heat Pump installed two and a half years ago by Pathfinder Plumbing, Kenmore in Brisbane. We have been thrilled with its efficiency, and quietness. Phil Gilliland came when he said he would, and performed the installation to the highest standard. Recently a small part caused a leak at the top of the storage tank. Phil came immediately, and fixed the problem at no charge. I cannot speak more highly of the Sanden pump and Phil's professionalism.
Not happy with the product
I had a Sanden system installed 5 years ago and have had problems with it the whole time, we keep getting error EO40 on the heat pump which trips the system out All the time, have tried cleaning filters, putting new in line filter on, have had no help from the initial sales person, very disappointed with the after sales service, even from Sanden head office, no one seems to want to fix our problem, looking at replacing it, a total waste of $10,000.00
Sanden Hot water heat pump
I purchased the Sanden Hot water heat pump after hearing great things about the performance of the system which uses carbon dioxide refrigerant. We have found this is a great product that uses a natural refrigerant that works with minimal capacity loss right through Tassie winters, and is so cheap to run. I was sceptical at first but the system is definitely worth the investment over a conventional electric HWS. My power bill for just hot water dropped easily by 75% after installing one.
Well, apart from being very quiet, this thing is very cheap to operate, costs seem to be about a third of a 2.4 kw conventional hot water service and with the 300 l tank draw down is never a problem even with 4 people in the house.
The only point I would make is that the inlet water filter has blocked twice causing the unit to trip out but that was after we had been away for two extended periods of time hence there was no flow through the unit and I suspect a little algal growth may have been the cause of that. The fix is simple, turn the wate...
Excellent Water heater
After over 5 years of problems with a Rheem Heat pump water heater we decided to replace it with this Sanden Eco Heat pump. Peter Hungerford, who installed it is a real deal, the Sanden has been working well, and very quiet and no more complaints from my neighbours. This water heater is the best.
Does everything I was told it would do. Quiet and efficient. I especially like being able to utilise my solar panels power production during the day to power the system. Sanden allow you to simply program when the systems mandatory daily heat cycle occurs. Innovative solar water heating that's located under the house out of sight.
Amazingly quiet and efficient
Four months ago we replaced our off peak HWS with a Sanden heat pump and 315 litre tank. This is an amazing system. When first installed the weather was cold and it took only two hours for the water to heat, using about 3 kW. Now, in early summer, heating is taking just over an hour and using about 2 kW. We have set the operating time to commence at 11 am (EST) to make the most of our solar system. The pump is so quiet, barely audible when standing nearby. It will be interesting to look at the power consumption over a year - at this stage it lo...oks like the saving will be about 70-80% when compared with the off peak system. We couldn't be more pleased with the advice and service provided by Breaze Energy Solutions, Ballarat. Simon assessed the site and our requirements, answered all our questions and followed up to ensure we were happy with the installation. Overall, we are greatly impressed with the Sanden heat pump.
We enquired about a Water Heat Pump & looked @ lots of reviews on all brands of units. After serious consideration we decided to settle on a Sandon Eco water heat pump. When we first heard the price of the unit we were abit put off but realised if you want the best on the market that's what you have to pay. Thank you Peter Hungerford from Energy Solar Solutions for all your advice & professional workmanship & installation on the unit. We are very pleased. We would not hesitate in recommending Peter in doing your job.
Ps.A big thank you again Peter for a perfect job well done.

My partner and I were required by council regulations to install a solar pergola or a solar hot water system on our build. After reviewing our options, we were not too thrilled. Whilst we desired solar hot water, our limited roof space would have made it impossible to invest in solar energy in the future should we choose this option. Then we heard about this heat pump. Well, it all sounded a little too good to be true and, after the rebate, was not that much more expensive then installing solar. We decided to give it a whirl. Well we couldn't b...e happier with out decision. Six months on we've had no issues. The pump itself is so quiet we forget it's even there. There has been no impact to our electrical bill and we have a constant supply of hot water. My partner and I love our heat pump and would readily recommend it.
heat pump on new house
After reviewing builders choice for the heat pump on our new house and researching what was available I am glad I decided on this unit. It is efficient in power use, quiet in operation and I haven't had an issue during 4 months of use so far.I live in SW Western Australia and was worried about low ambient temp affecting performance during winter,even at temperatures near zero this unit continues to produce consistent hot water to my house, I would recommend this unit
A quiet achiever, far superior to our old Quantum 340 heat pump.
After our 6 year old Quantum heat pump imploded due to electrolysis we checked the reviews on most efficient and cost effective hot water alternatives and settled on the Sanden Eco 315 heat pump which best took advantage of our solar array.Ben Cole from Newgen Solar in Melbourne visited us to outline the attributes of the system which included very quiet fan operation, stainless Australian made 316 tank with a 15 year guarantee, ( no annode needed ), quality installation and removal of our defunct unit. He took care of the govt. rebate and true to his word had the whole thing organised to be installed the next day. Cost with the rebate was $4500. I will give you all an update when the unit has been in operation for 6 months.

Quiet as a mouse, efficient, money saving
Have had our Sanden Eco Heat Pump 315L for just over two months now. Runs on overnight tariff for a household of 5 and have had hot water 24/7 with no issues. The unit is so quiet when running it is unbelievable (yes I got up in the middle of the night to listen to how quiet it was) The Sanden replaced a 15 year old Rheem 250L electric storage unit which was using 11.5kWh a day on average. In comparison the Sanden uses 2.6kWh a day on average since install to heat a 25% larger tank of water . On the Sanden website they state a saving of 78% over a conventional storage hot water service. My figures absolutely support this claim. Loving this amazing product
not suitable as an hydronic hot water system - as the retailer advertised
Sanden are a good company in our experience. However do not purchase this System if you plan to use it for Hydronic heating your home. Enter Store in Eltham advertised and sold it for this purpose and it doesn't work efficiently nor does it heat as it should. I expect it would be OK for hot water alone. There is lots of info from Sanden as to its effectiveness. but under no circumstances buy this thinking it will work, as Enter Store have advertise, as a solar heat pump for hydronic heating, it was Not designed to do so and don't let them tell you otherwise.
Pls note I'm rating this for hydronics not hot water
Peace of mind. Simply quiet and efficient
Quieter than my aircon and only cost 1/4 electricity to run.
Yes the up front cost is pretty high but it will pay it self back in about 3-4 years.
Would never live without one if we ever moved.
And the unit is pretty smart as its a separate system so you only need to replace one unit if the tank or heat pump broke
Questions & Answers
Hi, we are thinking to get a heat pump system for our place. We have three bathrooms (one of which is used infrequently for visitors). Will the heat pump heat enough water for showers for all these bathrooms, if we have a full house? Would hate for people to have a cold shower.
Who can fix mine, I live in Lancefield Vic, it loses pressure and water goes warm, Sanden inform me they do not have anyone in my area
Where would the ideal spot for a ring main return be plumbed in on a Sanden heat pump...?
Would it be (A) where the hot water goes in to the cylinder from the heat pump, (B) where the cold water comes out from the cylinder to the heat pump or (C) where the cold water enters the cylinder from the main cold water supply...?!
