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.

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.
Please help.

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?

Wnat temperature is the hot water set at?

I think it is set around 60. When installed, the plumber went back and forth between the unit and the hot water tap furthest away until he was happy with the temperature, so it could even be higher. It does feel geat when using it though.

Hi Jim l am a Fully Licenced Plumber and recently installed a Therman 26 at my own house and from day one have the same problem you are having. I have tried everything possible to rectify this myself and are waiting on Reece to contact me after Christmas, I am very disappointed in this unit and at the moment will not install any more until l can get it sorted. I will let you know how l go. Cheers Paul.

Probably the shower heads water saving device that's causing the problem

Catalyse

Did you know that instantaneous hot water systems (HWS's) require a certain amount of water to pass through per second to stay active? For example if you turn your hot water tap on really lightly you will notice it doesn't stay hot. So low water pressure is the issue causing your problem. That said, low water pressure can come from 1 of 3 things:
1) you have low water pressure to your property (the least likely in suburban Australia)
2) you have a water saving shower head that doesn't allow enough water through even on full pressure (most likely, just remove the flow restrictors in it, sometimes 2 inside)
or
3) You have installed the HWS without a controller, and therefore have to use a tap to mix hot and cold water to get the correct temperature. Thus using less pressure from the HWS and substituting some or maybe even half of the pressure with mains water. In this case you will need to have a controller installed so you can run the hot water on max with no cold water mix.

Good luck!
