Absolute piece of crap. Broke just after warranty expired, fixed it and it broke again 6 months later. Pure rubbish
Rubbish product, expensive to purchase and fix, with only one authorised repair person around. They are now an Obsolete products due to being an inferior product. Sorry I have nothing good to say.
Purchased in April 2015 for $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.
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.
Questions & Answers
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?
Quantum heaters are 'mains pressure' units which means that the storage tank is pressurised by the cold water inlet. Except for minor losses of pressure from the valves and pipe constrictions the pressure out should equal the pressure in.
It seems like yours is a plumbing problem. Good luck with it.
