published

I had a gas storage hot water system. The gas bill was so high upto 300 dollar. I have get plumber to install the quantum heat pump hot water system. 270L. I am so happy. My electric bill does not gone high as I was afraid of and my gas bill gone low to 40 dollars. This product is very reliable and highly recommended.

Not worth the money

published

First impressions were good. Good savings on power bill after an initial outlay of $4500.00 it had just paid for its self after 6 a d a half years.
We fisr noticed our water pump cutting in and out a short an regular intervals, thinking we need to replace our pump after 20 years (can live with that) we then noticed a leak in our heat pump. Need a new heater there goes the savings. Were too from here?

How do I get Quantum to ring me back???????

published

I installed my current heat pump in November 2006 and have had relatively no trouble until I tried to order a top lid, which has badly rusted. After my initial ring to head office in Sydney, I was told the part was available and to just ring and order, simple really(really????).
I rang two days running and left the requested voice mail message with my query to order and the requested call back details - still waiting to be called back.
Subsequent to this I emailed the General Mangers P A and, guess what, still no response after approx. 3 weeks.
Would I recommend their after sales service, hardly.

Just over four years and they are all falling like flies in a Mortein storm.

published

I have NINE of these units on my property and due to poor manufacturing and an abysmal component failure rate I'm down to two that still function. One is working, the other needs to be coaxed into working as I have been told by a technician that certain electrical components were not made weather proof from the factory. More over, just trying to get a tech to fix these things takes upwards of a month and last time (and very much the last time!) I was handed a bill for nearly eight hundred dollars. At least when they stop working you can tell by the flash and bang from the electrical part that isn't weather rated properly as it arcs itself into oblivion.

not happy!

published

Thought we would save money with the energy efficient model, it lasted 6 years and the tank burst, the initial cost was approx $4000, so what we saved in power we just lost in having to purchase another hot water heater, but certainly not another Quantum very poor product life.

Quantum Heat Pump Under 3 Years Life

published

Quantum heat pump split after nearly 3 years. Quantum sold me a new one for 1400.00 delivered but still! They also get to keep the rebates. Cost of plumbing, electrician, etc. makes for a pretty expensive heater.

Steer clear

published

No problems here.

published

We installed a Quantum system (Heatpump hot water) in 1993 when we built our present home. As it's an old one you cannot get the gas (R21?) for it now but it's cheap and trouble free. Ours lives in the corner of the garage and makes little or no noise. This model has collectors on the roof through which the gas flows and exchanges the atmospheres heat. It seems to work best when it's raining or blowing and uses 500W. $20 a month for hot water....

Fantastic - Quantum hot water system

published

Hi, we've had our Quantum 340L heat pump installed for about 5 months now. We live in the Adelaide Hills and run the system using off-peak electricity. It has worked perfectly even during the cooler nights. Compared to our old element system (also used off-peak) we now only use about 20% of the energy. Our annual electricity saving is $650 pa (daily cost to heat water is 40c vs $2 per day). I was concerned regarding the noise from the other reviews but they aren't very noisy. We have ours located outside the kitchen windows and have trouble hearing it from inside the house. Fantastic. If you are looking for a reliable installer in Adelaide we used SA Hot Water and they were superb.

Cheap efficient water heater

published

We have had our 250ltr quantum heat pump for 9years...replaced small white cylindrical solenoid 3 years ago but no other issues. It runs for 2-3 hours like an inverter aircond so don't place unit near bedrooms. Our electricity bills are very low with this system on off peak1...wont heat up enough on off peak 2 as we discovered. Would highly recommend this system

Thank you Quantum Energy!

published

Just updating my experience with expensive and ineffectual repairs to our Quantum Energy Heat Pump (reviewed April 18). Thanks to Quantum's intervention, their service agent yesterday refunded the amount charged, less the call out fee which we agreed to pay.
After four weeks with no hot water we are now able to purchase another hot water system.

Good Product - Very Efficient

published

Our Quantum has just died after approx 20 years of use. Very cheap hot water. It was in the garage and we had no problem with noise or rust. We are going to replace this with the smaller 200L unit as we don't need the bigger size.

Noisy yes but used little electricity and compressor ran for 14 yrs. About what you'd expec from a fridge or similar. Hoped for more but pretty happy.

Stress purchase of a Quantum 270, by a high priced installer

published

Noisy & Unreliable - avoid!!!

published

Unfortunately installed these units six years ago and put up with the noise throughout that time. Neighbour thought we must have a very clean house as she thought we were using the ducted vacuum all the time! May have been more energy efficient, but having to switch from off peak to peak power meant they were no cheaper. Broke down after warranty and thankfully only $300 repair. Lived with these units until we sold the house and moved. Have nothing good to say about these units. Never again.
