I'm unsure of the model, but my proflo gas water heater is large. I had the Thermocouple replaced March last year and the plumber cleaned the ignitor or something that had a little soot. Now it is again switching off after a day or so. The themocouple and pilot looks fine. To me it looks like an airflow problem. The only area I can see where there is air flow is right at the top. Alternatively I could remove the panel at the base. I heard you need to clear dust.. but at the top.. can't see any. Please help. I rather check first before paying ridiculous $'s for a plumber when I think this is more of a safety shut-off due to air flow restriction. PS.. I cannot read the serial/model but thinking it's at least 5 years old. The paper etc is worn away.

We have just had a brand new Dux 315 L electric hot water system installed after Christmas. It has a water hammer after using the hot water that will not stop unless we turn the hot water tap on slowly and then turn off slowly. Recurrs hours later, often in the middle of the night. Daily problem. It started within 10 days of installation.

I am thinking of replacing a HardieDux HDE125l November 1988. I think it’s a dual element. The base is rusting badly. It is in a holiday home - indoors. I have had no problems at all but it won’t last another 30 years. I’m looking at a 250l continuous tariff as there are more people at peak times. The property is on an island so I’d use a local plumber. I turn the heater off if we are away a few weeks. Is this a good idea? Can I get a 250 dual element?

Hi Frank, We currently only manufacture 315L twin element tanks. If the unit is not being used for a period of time, the power to the element should be turned off. The power to the tank should be switched back on about 24 hours prior to use to allow the water to heat to temperature and be properly sanitised. Before powering the tank back on, open a hot tap fully to discharge any air that might be trapped in the system. Best Regards, The Dux Team

Do you need to remove the plastic insert's in ports before pluming?
3 answers
Suggest you contact DUX at: help@dux.com.auThe plastic inserts are there to prevent entry of foreign objects before installation. They should be removed just before connection.Hi Rassie, The plastic inserts are part of the internal plumbing of the unit, they are not removed. The plumber simply screws the nipple into the socket and in turn the nipple screws into the plastic, this is a part of the product design. The plumber still uses their normal sealing methods on the nipple. Best Regards, The Dux Team

Hi. My proflo 50l is brand new snd keeps activating circuit breaker in main meterbox. I pushed the reset switch the first time this happened but now its bypassing the the unit and settling off house breaker in meterbox. In fact this happens as soon as you plug the unit into the PowerPoint. Could this be fried thermostat or possibly dodgey element? PowerPoint has been checked and no fault there. Any suggestions for a remedy to this problem would be appreciated? Thanx Scottie.

But, suggest you contact DUX at : help@dux.com.au ..... and/or a good local Electrician.Hi Scottie if the unit is brand new you need to get back to the manufacturer or supplier/installer. it seems like a product fault

Can the "seal' on the base of the sysytem be replaced as water is leaking from here?
2 answers
Dear Janelle, our system has just been installed and is brand new. If a seal is faulty it most definitely is replaced under warranty. My understanding is that we have a ten-year warranty of which I am yet to test. Under consumer law this warranty could be extended depending on how long such am appliance should really last. I would immediately contact DUX by phone and or email with a Mobile photo if possible and get them to replace the seal under warranty it should not be leaking. If the seal cannot be simply replaced then DUX should replace the system.Hi Janelle, Thanks for your question. Please contact our After Sales & Service on 1300 365 115 Option 2 with the serial no. of the unit and to arange a service call. A leak at the base could possibly indicate an issue, one of our Service Agents would need to attend to inspect. The 50W136 has a 7-year tank leakage warranty. Thanks, The Dux Team

I'm trying to set a timer on my 50w1 to utilise my solar panels . It is currently set from 4am to 9am and 4pm to 9pm and there is plenty of hot water. But from 4am to 6am there is no sun and 7pm to 9pm there is no sun so these 4hours are on grid 3.6 kwh x 28 cents per day. I'm thinking of changing it to 5am to 9am dropping 1 on grid hour and 2pm to 9pm gaining 2 solar hours. How long should the water stay hot if not used?

Hi Martin, Thanks for your question, our Product Specialist team will get back to you shortly. Best Regards, The Dux TeamHi Martin, 50L heaters by their design (same for all manufacturers) are not as energy efficient as larger heaters such as 250L and above. A lot of external factors will come into how long the water stays hot in the heater, from the ambient climate to pipe insulation, etc, etc. We cannot advise on the blend of PV input vs on-grid supply. From cold to hot, the unit draws 15A/hr and reheats in approximately 50 minutes. A solar PV electrical engineer might be able to advise further. Best Regards, The Dux Team
