New tankless water heater question

Wouldn’t I smell it in the house then by the unit itself if it was leaking in the pipes around it?


I would think so, mine is mounted outside the house, in FL that's an option and it eliminates putting in the exhaust pipe/vent.

Not necessarily. The excess unburnt gas might be going out the exhaust pipe. That's why you smell it outside, but not inside the house. The Rinnai unit on the house I managed, was mounted on an exterior wall at chest level and you could stand 1' from it and NEVER smelled any gas, ever. Running or in stand by.

I installed my Rheem tankless unit in 2009 (we LOVE it) and I've never smelled natural gas around the exhaust.

If you are smelling it and they detect it when it's off then by all means call the installing company.

Mix up a bottle of water and dish washing soap, spray the connections on the hoses going to the unit, see if there are any bubbles, if so, that's the leak, you can do that yourself.

We have a Rinnai Unit on the house, smell no gas when it's running or not, we did have a time where you would smell gas, had the company out and they determined the valve on the LP tank had a slow leak.

He stated "valve on LP tank" (as the one sitting outside) not "valve inside water heater". Wink
Of coarse you don't have a tank, since you're on natural gas. Smile
