Hi Darryl,

Please ensure that the power to the solar module is left turned on at the power point, this will allow the solar module to circulate water to the collectors, providing frost protection.

The element can be powered on, but it should be powered back on a minimum of 24hrs before first use (perhaps arrange this with a neighbour), this is to ensure that the water is sanitized in accordance with AS3498.

Also run the taps to bleed any hydrogen out of the tank, ensure that there are no sources of ignition when this is occurring.

For any concerns, you can email directly help@dux.com.au.

Hi Rod,

Thanks for providing the details and raising the question.

There are no precise figures available on the running costs of an electric boosted solar water heater as there are too many variables.

Factors such as the location of the system, the orientation and pitch of the collectors, variations in UV radiation (which is what provides the heat input), hot water usage patterns as well as what is charged per kW/hr by your energy provider meant that even an average kW figure per day is difficult to give.

As the tank is boosted for 1/2 the storage volume only, worst case scenario there is little to zero UV input and the boosted volume of 200L is used in a 24hr period, 11.6 kW of energy will be consume heating up that volume to 60 Deg

The hot water pressure inside the house has dropped significantly to a point where you can't run two tapes simultaneously. Is this something that is serviceable or am I better spending money to replace a 13 year old unit??

Sunpro DN15DS (Storage Tank, Natural Gas)

After a day of cloudy weather we have no hot water next morning as the gas booster is not working.
I can get the booster to fire up after turning the power off for about 30 seconds.
What is wrong with the unit, does it need a component replaced. As well as this,the frost valve has decided to toss it in with water pouring out everywhere. I have temporary capped this as I don't want another $500 water bill like when this happen last time. This is very poor for a 4 1/2 year old unit and I feel like lodging a claim with consumers affairs (V cat) because the warranty is useless.

Hi Bill,

There may not be enough solar gain at your location to heat the water to 60 Deg C (the minimum temperature under AS3498 to sanitize the water from Legionella Bacteria).

Please check that the automatic boost element is turned on.

When it is very cold the gas boost will work but when the ambient temperature is above 7-8 degrees it won’t cut in. Can anyone help with this issue, cheers, Barry

Hi how long should the circulating pump on the hot logic run for before stopping, is it normal to be running constantly?

2 answers
Roy
Roy

When the sun is shining it is normal for the solar unit click in and out during the day. Hope that helps you.

Dux
Dux H.Dux

Hi Shane,

There is no set time period that the pump will run. Everything will depend on the temperature of the water in the tank and how hot the collectors are.

When the collectors are 10 deg C hotter than the bottom of the tank, the pump is switched on, circulating hot water from the collectors back into the tank. The pump will keep running until that differential is 2 deg C and the pump shuts off.

This cycle repeats until the tank top reaches 85 deg C or there isn't enough UV input to make the 10 Deg C differential.

Dux Prodigy products are not designed for connection to solar collectors. Sunpro is the product you need if you want to go Solar. New installations may also receive government STCs - you can read about the current STCs on our website at www.dux.com.au/rebates.

Thanks for advice just replaced burner senor after the logic controller and we have got water and a lit less money but although we have got water if you turn a tap on during shower it goes cold which never happened before and shouldn't so what would cause this. We have dux sunpro solar. This is meant to be our save money period.

Hi Ewan,

We would suggest having a plumber or one of our Service Agents inspect the Tempering valve as that may require servicing or replacement.

A tempering valve needing servicing/adjuistment/replacement could display symptoms similar to what you are describing.

Please note, the DN15DS boosts by gas the top 50L of water in the tank, the balance of the tank is heated by the sun when it is available.

High hot water use might exceed the booter's ability to replenish that 50L.
