Don’t buy. It’s a piece of rubbish
Don’t buy this system. It’s so crap and it’s not economical at all. Also, organising a service is impossible especially if you don live in QLD.
Please stay away from this piece of rubbish.
Poor Reliability Expensive
New Quantum heat pump hot water system installed to our newly build house in NSW. It was supposed to be a “great system”. The system was installed in early 2016. In May 2020 the valve started leaking. The warranty is only for 4 year so we are out of the warranty period. We have had a plumber look at it and recommended that the unit be replaced because it is not possible to replace the valve due to the way the tank is built. We have been told to stay away from this product, very costly and even more trouble to fix.
Think twice before buying this brand or product.
Purchased in February 2016 for A$5,000.00.
Eye Watering Maintenance Costs - Disappointing
Purchased 2 May 18. Have zealously tried to maintain it since then. Required $1,207.80 worth of maintenance on 8 May 20. Problems getting hot water and problems with low pressure, fluctuations in pressure and some damage to plumbing fittings on 6 May 20 and water running uncontrollably until 7 May 20. We have yet to pay for those repairs as well. Unfortunately doesn't live up to hype, expectations and costs associated with this unit. Feeling misled. Probably should have looked up this site before buying. Reminds me - It's Mothers Day this weekend. Am a bit concerned about a larger Quantum Model I previously bought for my mother's house.
Purchased in May 2018.
Dreadful Customer Service
This is our second unit & the first one lasted over 10 year this one hasn't made 18 months!
We have been without hot water for 5 days & were told by customer service that the repairman would call to arrange a service call but guess what NO CALL! several calls texts & emails to customer service but no answers. I'm sure they are waiting till we give up & go to a local hot water service provider so they don't have to provide the repair under warranty. All we want is to know when they will come so we can be home, make ongoing alternate showering arrangements & get on with basic living.
Purchased in July 2017 for A$3,200.00.
terrible and unfriendly customer service and making noise like a monster
1) terrible and unfriendly customer service
2) quantum machine makes noise very loud, same size machine, the next door unit is just quieter than mine.
3) they sent a technician to check, only stay for very short time and let the water out, and the technician checked the neighbour's machine (same size), even the technician said to me and the neighbour, mine is louder than my neighbour's. and I asked the technician if he can live somewhere like this, he said not really. The technician even didn't check the internal of the machine at all. But he s...
Never ever Quantum again.
Certainly I am very disappointed in Quantum as a company. We have several cylinders of which 1 has had to be replaced as it sprung a leak. Another has has a major repair done which Quantum refuse to acknowledge so I am left with the cost. Dealing with Quantum would rate as a "very bad experience" it takes heaps od emails and heaps of phone calls to get to any conclusion. Would never ever purchase anything made by Quantum ever again.
not a sustainable item
These, in theory, sound like a great alternative to reduce electricity costs. When you consider the exceptionally short life (8 years) and the annual costs of maintenance these water heaters are a very expensive system. Steer clear, the quality is not there and it was next to impossible to get after sales service
3 Units Installed All Failed with Leaking Tanks
Purchased 3 Heat Pumps and they worked efficiently. 2 of the units started leaking water from the tank and were replaced. Unfortunately the replacements did the same thing with the water tanks failing and leaking. The 3rd tank did the same and now quantum are refusing to fix the problem and I am off to the Consumer Tribunal to seek redress. I would not purchase a quantum product again as there are doubts to the water pumps durability and longevity. To have all 5 units suffer the same issue does not say much for the product
Excellent hot water service
Bought in 2008 and has given hot water in our cold climate with no need for boosters that other makes (Rheem) need. It runs, quietiy, for about 4 hours mid winter. It needed one service call to replace the starter capacitor for just over $100.
It's a pity our new house has Rjeem which is noisy and runs nearly all night.
no longer convinced
i researched these and was more than happy to buy.. it worked for about 3 years and then started to fail.. they came credit to them and replaced it as it was inside warranty. well 5 years down the track.. its happening again. What to do when u dont have money to replace them and u know longer have hot water. some major issues they need to sort out.
Technology at its worst
Purchased the Quantum Energy 340L heat pump in November 2009. Assured of its quality design and green house gas saving technology. After 2 years the inadequate electrical connections which were not weather proof failed and cost $350 to fix. Now after the 5 year warranty has expired the unit has begun to disintegrate due to electrolysis. It was an expensive purchase at $2750 installed and has proven to be very poor quality in terms of value for money and longevity. I would not recommend Quantum Energy products. You cannot contact them on the phone and the units cannot be fixed. Do not buy from them.
We have had our Quantum Heatpump for 5 and a half years. Warranty was only 2 years. At 3 years had to have the control panel replaced at a price of $580. Two and half years later, the control panel has needed replacing again. To say we are disappointed is an understatement. Would not purchase another nor would I recommend a Quantum Heatpump.
8 years old and leaking from the top.
We have a Quantum 315l cylinder, it's only 8 years old and it has rust all over the steel tank.
It's leaking from the top and you can push your finger through the steel tank up on top.
It's now the second one to go in 4 weeks.
It's for a Hotel, customers are always complaining about the noise.
Good enough for 11 years
We are now shopping around to replace our Quantum Unit after 11 years. It has been efficient, but noisy. The fan now needs to be 'kick started'. We will probably change brands as Quantum want $800.00 to replace the old one. We have never run out of cold water. It takes about 6 hours to complete a heat cycle from a cold start after a holiday.
Hot H20 from the air
We have a quantum water heater that is 9 years old.Had a new capacitor replaced 3 years ago.PLEASE NOTE-the water anode should (ideally) be replaced every 4-5 years.These anodes start off being about the thickness of a thumb and may end up about the thickness of a match!We run ours on a day tariff as the air is GENERALLY warmer than at midnight(the supposedly cheaper tariff time?).The price u pay usually dictates the savings. Also i see some reviews that say that their heater is in the shade!!- it doesnt matter-its all to do with the temp of the air!
Load of [censored word removed]
i have had the hot water unit now for 6 years and every year in winter it brakes down do not buy one the most expensive to run hot water that I have own. next time it brakes down it going to the tip and I will install solar ..
Sick of spending money on it
Need new capacitor evey year
Have had it for 3 years. We have the 340l which we were told would easily cater for a family of 4. Well, It doesn't. In winter we are constantly running out of hot water and it has just happened again. Fed UP. Cheap to run but you freeze in winter.
Doesn't effectively do what it is supposed to do i.e.Heat Water.
I think it's great.
We have had our unit since our house was built, finished in 2008. It has always worked well even though it is situated on the south side of the house. It is partly protected from the weather by the eaves and doesn't get any sun. It has had on one fault when a capacitor failed, easily fixed. I run it on a timer so that its not trying all night through the winter to heat water from cold air. I run it from 9am to 4pm and it usually only takes 2 to 4 hours to reheat. When we go away we turn it off, then when we come back it will heat up overnight even on the coldest nights.
It's cheap to run and reliable
Quantum's Heat Pumps are fantastic.
We live in an all electric house with a 2kw solar array that offsets our energy use and some. All in all, our total energy use is 4-5 kw a day and we generate around 10 a day in spring . I attribute our low total energy use to the Quantums ability to heat without a coil for a booster. I couldn't be happier. Solar Hot Water systems are becoming increasingly complex to install where as the Quantum can be located at ground level. We draw air from our sub floor to lift the intake air temperature therefor improving performance and are planning to ...use the exhaust as air conditioning with a inline fan and ducting. We have been party to 4 installations of Solar Hot Water and the complexity of additional load, diversion for glycol leakage, roof penetrations and the sheer visual weight of them as objects on a roof has made me adamant that I will never install a solar hot water system again Efficiency, Cost, Simplicity of installation
Questions & Answers
My quantum hot water service only gives me Luke warm water not HOT why
Just bought a house with a Quantum water heater and find the hot water pressure to be very weak. Is it common with these heaters?
I would like to know if different climates have a bearing on the performance of this product, I have read good and bad reviews about this we live in QLD Sunny Coast, so not sure if this would have an impact.
Yes, the warmer the air temp is, the quicker the system heats the water. I'm in a coastal suburb in Nth Brisbane, had my compact 270Ltr for 13 years, it provides hot water for 2 adults and 3 young kids. In that time all I have replaced is the anode once,(about to do it again) and installed a 24hr timer. The $200 timer, I believe is the reason my system has lasted for this long. I installed it because -A- I only need to heat the water once a day during the warmest part, the afternoon. and B- I have neighbours living about 3mtrs away, we get on well and I'd like to keep it that way. The fan is about as loud as an air con unit, which is fine during the day but not at night. It is a good quality timer, hard wired inside the house so I can easily flick a switch to override the auto function, in case I have extra guests or weather is not favourable. It has been a very good reliable heater for us as it should be for you. Mick
