And just because you did not experience the above does not mean there isn't an issue with these units. Hope this is a fair statement.

Its strange you come here praising the forum owner but won't address the oil found in in your boiler, the issue with your boiler is not just a reliability issue but the high cost price by installers, the high maintenance fees and the high cost of repair once an installer finds out the home owner...

If we had a hurricane Sandy once a year and affected by it, it would still be more cost efficient to steer clear of a Navien thankless.

It would take years to make up for the outrageously over priced installation costs when compared to a conventional water heater. A $400 water heater plus $700 to install at most vs a $2000 tankless with a $5000 installation price tag, thats aside from the constant failures of sensors that on...

Also still unsure why anyone would change out their tank water heater thats been maintenance free for years and easy to replace when needed with the above Navien.

The unit is not converting plastics into oil, the oil is fabrication oil used in the making process of the heat exchangers and other aluminums. Once its wiped down once it will not return. Navien wont admit to it and will try to blame it on the exhaust pipe being too close to the intake and...

Ensure you report this to the below agencies, very curious what an investigation will find by your plumber. https://www.saferproducts.gov https://www.cpsc.gov/

What's more astounding is homeowners will still consider them.

That's unfortunate that that's all you gathered from his post.

This should be pinned to the top of the Tankless forums. Electric tanks have been nothing but reliable, near maintenance free ( Anod rod and elements maybe every 5 years), great on energy usage, cheap installation cost and any plumber can work on them, no venting pipes, exhaust or gas needed...

Just noticed you replaced the Flow switch. Disregard the below but might help someone else.

Just curious if that's a Monoflo setup with a loop in the basement. If so ensure the arrows are pointing in the right direction on the Monoflow valves. You can see this arrow faintly on the valve below. If it is indeed a Monoflo, I would investigate around these valves...

Upfront cost for a tankless plus installation plus maintenance, lack of support from companies, will render these units highly inefficient when compared to a tank water heater that costs fractions. These units are popular in Europe due to small size apartments without basement access, a...

Sounds like your running on a curve using temp readings from your outdoor sensor and since its still warm in NY it will do what you describe and stop around 140, when it gets colder it will reach the 150 or whatever yours is set to but it will pass the limits your currently seeing. Ensure your...

Why not just tell him and everyone what it really is instead of wasting everyone's time?
