[QUOTE="Frederick, post: 3671598, member: 17825"] Depends on installation. If its vented straight out, no. I am a licensed plumber in OK and I've installed naviens and rinnais. I personally would always have a 40 in my house. The thing about an instant hot water heater is that there is a lot more to go wrong with it, and I've seen the bills for replacing parts in a navien water heater. You need to run a cleaning solution through the isolation valves every 6 months but that's not a big deal. If you live on well water, I would not get a thankless. The high calcium content would eat through your heat exchanger very quickly. You can get a water softener, but that only mitigates the issue. Personally I would change my annode rods every decade or so and flush my water heater every 6 months if I lived in the country. Ymmv A navien is cool but personally 30 to 40 years on a 40 gallon tank is a no Brainer for me personally. Only makes sense if you have a specific need to go tankless imo. [/QUOTE]
