We bought ours about 3 years ago, a 150L model. In the Adelaide hills, so relatively cold. Has been very reliable, only had the relief valve leak but that was replaced free of charge under warranty. Fairly noisy compared to the newer reverse-cycle aircons.
Hard to know who is astroturfing in these reviews, but at least my review can't be taken for that...
noisier than it needs to be
runs a lot in cold weather
Ok but not as cheap to run as expected, not as reliable, nor as quiet as I expected.
Should have installed in on north side of house - so would have been in hotter environment.
Supposed to be efficient - when it was new, it seemed to be!
We have an earlier model (1999 or 2000, I forget). It is not storm rain resistant - heavy driving rain will get in via the air vents and drop/run/pour down onto the unprotected controller board. Quantum have developed a rain cover for the board ($50) probably fitted now on newer models - but Quantum never cont...
Produces cheap hot water however if you can use solar hot water (like I had on previous house for 20+ years with no trouble) do so. What you may pay extra in initial cost will be worth it for the convenience and maintenance savings of a passive system.
I bought the domestic version in 2006. At the time the RECS were only worth $300 so cost me $3000 for the system alone. Has been running (well mostly) for 3 years and does indeed save power and the hot water recovers well after being turned off when on holidays.
It is noisy however I live on a...
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?
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.
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
Cheers for that valuable feedback Mick.
