Unreliable

We get very frustrated when using the app to put our heating on as the flame light comes up to say it is activating and heating should come on - then you look a while later and it is back off again or flame indicator is off and the boiler has not come on. Very unpredictable

Awful

It’s awful. Doesn’t work, each function has to be done twice to work . Doesn’t connect frequently

Useless wireless connection

Changed WiFi and now stopped working

Very poor app

Absolutely useless! The navien app often fails to load on my iphone and the navien boiler regularly displays a fault of a blocked exhaust port. Which is a design fault apparently. I would not recommend navien to anybody. Rubbish.

Fails

Not good, wouldn’t recommend. You wait for it to connect, no problem, you input a temperature, it’s loads, no problem, you think it’s working, it’s not.

Navian heating/water system

The heating comes on when it shouldn’t (summer) despite the control AND app being set to ‘OFF’ The water is set to ‘INTELLIGENT’ which changes randomly to either’OFF’ other settings.
Engineers have been out three times within a year not to mention numerous visits from the fitter himself!
On a plus side, when it does work without a hit hitch, it’s fine, but the inconsistency drives me mad. In my opinion, I thinks it’s a waste of 7.5K

Unhappy

I’ve had the Navien boiler for 3 years and since the new technological thermostat was installed I cannot use it.
I don’t want 6 programmes.
I want to turn it on when I want it on and off when I don’t and I cannot do it! I’ve had gas people out to do it and I’m always sat in the cold with blankets to keep warm. Wish it was never installed!!!

App not working since update.

Water heating but not being timed.

Energy usage doesn’t work

On the whole ok but annoying when things change such as frost protection temperature changes

So disappointing 😞

New boiler, lots of promises and hype about the phone app. Has got better but loses info - history and glitches so all of a sudden it goes into holiday mode.

Holiday doesn’t work

Each time we set our house to holiday it broke and we could not turn it back on through the app

Recent updates have improved stability 11/25

I have been using this app for over a year now and am familiar with it. Recent updates have improved stability and it is a pleasure to use. Well done Navien developer team👏😀!

Smart App

As others have said the Smart app is very temperamental and typically requires the app to be fully closed and restarted. If buying again I would consider trying to find another form of smart controller as the Navien version is very poor

Leave well alone

The worst system ever. App is awful, boiler inefficient and unreliable. Out of action more times than it’s working. Would love to replace the whole thing

MRS JO

Very temperamental boiler and the APP is very annoying and unreliable. Very disappointed and would change to another boiler in a heartbeat.

Feedback

So love my Navien but my one grip is the timer on the app. It’s awful, your old one was must better. Can we please have it back 🤞🤞🤞

Could be really good

If the system has a fault the only way you know is when you notice the heating has not come on or if you happen to notice the error code on the thermostat! If Navien used the App to show error codes then you would know instantly because your device would be able to inform you, if set, immediately…

Not the best

Needs to be improved have to keep logging out and back in to get working, I had a hive system before this one and the hive worked perfect, so a huge disappointment, I was expecting better being the same brand as the boiler

Unreliable

Slow and often does not work.

Glitches

Good but the app glitches a lot. The data and graphs don’t work even though the boiler is connected. All in all I think you get what you pay for with the thermostat. Turning the heating on and off was the selling point really but the data and graphs would be much better to calculate usage etc.

If Navien invested a bit more time and money into the app they’d be on to a winner for sure
