Hey can you reduce the temp on these things?

Our water is insanely hot and no doubt uses way more power than is needed

Darrenasked

What causes the system to ice up?

3 answers
Dux
Dux C.Dux

Hi Darren,

It's our pleasure to answer your question.

The formation of ice on the evaporator coil is a normal part of the heating process, the same as with a reverse-cycle air conditioner that is in heat mode. This can be effected by variations in ambient temperature as well as humidity.

However if there appears to be an excessive build up of ice, it could be an indication of a problem with the unit. If you are experiencing this, can you email through your full name (state this username as well), phone number, address where the unit is installed, model number and serial number of the unit to help@dux.com.au.

Best Regards,

The Dux Team

Robin D.asked

Is this unit a solar heat pump?

2 answers
Dux
Dux C.Dux

Hi Robin,

The Airoheat is an environmentally friendly heat pump, without the need for solar panels. Here's the link to the product on our website - https://www.dux.com.au/product/range/heat_pump.

Would you like to talk through your needs? If you can email through your full name, phone number and the state where the unit will be installed to help@dux.com.au we can get someone to call you back if that helps.

Best Regards,

Hi Robyn
The aero heat pump is a heap of junk and should be taken off the market. Please read all the negative reviews and avoid this company. Definitely not solar. Electric heat pump that is gauaranteed to cause you grief and a whole lot of money.


Dennis D.

Dennis D.asked

Airoheat D2FH00000C

We have noticed Orange / Rusty coloured water coming from the hot water taps mainly in the mornings. We have a full copper cold water service. The orange / rust colour is not evident every morning. My wife normally has a bath about 10.30pm most evenings, and the water is not turned on again until the morning,. So we assume that when the tank is refilling after using hot water that is when this orange / rust coloured water is occurring. We had Sydney Water check our cold water supply and they could not notice any discoloured water. They even disconnected the house from the main stop cock and ran the water for at least 10 minutes. So does anyone know what is causing this problem, and is it a potential health problem. Regards, Dennis - Croydon - Sydney

Hi Dennis,

From the information given, unfortunately it seems that the tank is beginning to rust. Given the age of the unit, we would suggest replacement with another heat pump or a 250L electric storage unit.

Bob

Bobasked

Airoheat D2FHG3000C

Do these units have an anode fitted inside the tank ? If so how often should it be replaced ? Thanks Bob.

1 answer
Dux
Dux C.Dux

Hi Bob,

Our 250L Heat Pump is fitted with a sacrificial anode.

To maximise the life of tank, it's good practice to replace the anode at 5 year intervals (or sooner in areas with poor water quality).

This work should be completed by a licensed plumber in conjunction with a tank flush and replacement of valves as required. You can book in a Service call by calling Dux on 1300 365 115 or registering online at www.dux.com.au/support-and-aftersales

Choosing not to undertake this work will not affect your warranty.

Best regards,

The Dux Team

Hi Yes,

There is one accessible sacrificial anode, a suitably qualified tradesperson will be able to change it for one to suit local water conditions. Our Service Agents will be able to provide this service as well, please call our After Sales & Service on 1300 365 115 Option 2 to book it.

Is it normal for the unit to ice up during warmer weather? If so how long does the de-icing program run for. It has been going at least 12 hours now. The water being supplied from the unit is much hotter than normal.

Airoheat D2FHG4HW0C

Hi,
Do you have any instructions on how to replace the anodes in an D2FHG4HW0C?
I'm trying to determine if I need a plumber to do this or it's a DIY task.
Thanks.

Get onto your local Dux dealer, especially if you are still within their warranty period. They have an owner's manual which you should have got when it was installed. It will tell you more in that manual. If you didn't get one, ask Dux for a copy or download from their website. They now warranty their enamelled steel tanks for 10 years so it is reasonable to expect to get 10 years before any leaks. We had our first leak before 2 years and the replacement just over 5 years.

Do not bother - just go back to electric system

I have hydrotherm system also and it has been working a treat for almost 5 years.

My plumber totally advised against heat pumps but had not heard of hydrotherm which might be a good sign and I also have had fantastic experience with that brand.

Big NO to dux and rheem ! Problems from the very beginning!

The dual outlets allow flexibility to connect separate hot lines to the bathrooms as well as to the kitchen/laundry areas.

Dazasked

My Dux Airo Heat hot water system is 9 years old and recently came home from a holiday to find water leaking from one of the self tapper screws holding on the top compressor section. The screw is 25-30 mil long and was installed at manufacture on the outer metal casing join at the back of the system. How can this be fixed as it's obviously pieced the inner tank and over time broken through, is Dux liable even though warranty has expired?

I have a dux airoheat hot water system.My daughter just noticed that the water is not hot as usual.Its warm.The house was built about 7 years ago with dux airoheat hot water installed. Any reason for this before i call out anybody please?

1 answer
Dux
Dux H.Dux

Hi Otunba,

Thanks for your question.

it’s difficult to diagnose without a service agent going to site. It could be that the tempering valve needs adjustment or replacement, there may be an issue with the power supply to the unit that has limited recovery time for the product or perhaps the unit hasn’t recovered fully i.e. to full temperature after a large load due to the recent colder weather. This could relate to the tariff the unit is connected to.

We recommend you book a service by calling 1300 365 115 or go online at dux.com.au and click on the "After Sales Service" link to find your nearest agent.

Thanks

Airoheat D2FHG4HW0C

Thursday night water seemed hotter than usual.
Friday the fan didn't cut out and water started to cool.
Saturday water lukewarm and fan still going, no cut out. Sighted three green lights on. Turned off power. Restarted later - no change.
Any ideas before I contact electrician. I could not afford weekend callout fee.
