Reg Gasked

Hello I have a Therman 26 unit installed about 5 years ago. It has worked perfectly until 12 months ago. During a shower it will go cold for a couple of minutes. I have good pressure, plenty of flow going through the shower head and new taps. It seems to be worse in summer when running the shower at a lower temperature. Running town water and gas. Any suggestions?

Hi Brian,

So we can assist you with your question, can you please provide a detailed description of what is happening with your unit and your best contact details to update@thermann.com.au.

You may have selected the wrong type of unit as our Thermann continuous flow units do not have a pilot light.

Thanks

Hi Joel,

Thank you for your inquiry!

In regards to your question! You will need to replace the current controllers with the Thermann universal controller, as the electronics in the unit will not recognise your current controller!

Hi Brian,

Thank you for your enquiry. I would encourage you to contact your Plumber to ensure that there is power to the Thermann unit. Depending on the units age, 5* or 6*, there potentially could be an issue with the fuse?, due to a power outage or power surge within the property. If you need further assistance, Could you please log on to update@thermann.com.au , and a Thermann Technical Specialist will be happy to assist you in this matter.

We have just purchased a Thermann on recommendation from our plumber but finding that the water is just not hot enough, we are showering in just hot water and its still not hot enough, can the temperature be adjusted to make it hotter????

Hello - I had a similar issue if located in Vic, caused by the Thermann unit being tuned to 50 degrees as required by Vic regulations, My old unit was 60 degrees, the plumber never informed of this before replacing. Suggest you call Reece Plumbing who manufacture the Thermann, and work with them to tweek unit to increase temp if indeed you are located in Vic.

Mine stopped again tonight, whilst the lpg is half full, it would not work, flicked on the new cylinder and it was ok? Any ideas as to what this could be?

Hi Mr David Holder,

Thank you for your inquiry. The issue you are experiencing may be potentially caused by a faulty LPG regulator, but we would recommend that you contact your plumber and identify the static and working gas pressures.
We are happy to assist your plumber if need be? They can contact us via our website http://www.thermann.com.au/contact

Is there any way to stop the unit sounding like a car horn when a hot water tap is turned on or off? Our plumber installed it on the wall outside our bedroom and it’s driving me insane. It should come with a warning that it’s not a quiet device!

I have a therman 26. Last month was having a shower in the ensuite.. All of a sudden it went cold. I'm running on lpg. Thought bottle was empty but no. Turned on hand basin tap that went hot. Turned on the shower cold. Turned on basin tap again. Went hot. While still running basin tap turned on shower. Hand basin tap went cold. All other taps go hot even the other shower. As soon as i turn on the ensuite shower things go cold.

I just had installed the Thermann 26 GCF. Heater . So far no complaints.
Can you suggest a backup power supply option for the ignition were there is a power blackout ?
Last year we endured 3 days without power. So a backup option would be nice.
Cheers.

Hi Unimaton,

Thankyou for your review and we are delighted you are enjoying your Thermann Continuous Flow Hot Water.

The unit needs a continuous flow of electricity to operate correctly, 240v. May I suggest if you are looking for a back up supply you may need to contact a Solar PV Battery back up supplier as an alternative power supply.

Hi Mal D,

Thank you for your inquiry.

The answer to your question is yes. The Thermann Continuous Flow Hot water unit can be converted from Natural Gas to LPG. May I suggest that you contact your Plumber and he or she can purchase a Thermann Conversion Kit from Reece Plumbing.

Gas Continuous Flow 6 Star

I'm doing a new build and I'm thinking of looking at installing a Thermann C7.
Who does their warranty service work if I buy it through Reece.
I have heard that if there is a problem with them that they replace them but not service them onsite.
Is this true?
