I want to replace our water heaters before I have to replace them (we have 2 - 50 gal). They are 14 years old. The prior two we had only lasted 7 years before they leaked, soaking the carpet in the guest room and destroying the wall between the garage and guest room.
I’ve been looking at the Navien NPE-240A and wondered if anyone has gone tankless and how its worked out.
We have a hot water circulating pump now and the tankless heater comes with one. Our master bath (not intentionally offensive) is about as far from the garage as possible and still be in the house. Without that pump, I’d finish a shower before the hot water arrived. When the first pump died, we showered in the guest bath until it was replaced.
It is looped. We bought a new spec house, and the recirculating pump and loop were already in. Ours uses a thermostatically controlled valve, but I have seen them with timers or on/off switches. We just unplug ours when we’ll be away for more than a couple of days.
Tank or tankless doesn’t change how long it takes for hot water to reach a fixture.
My house was built with a hot water recirculating system that we regulate with a timer and a thermostat, which keeps the operating costs to a negligible amount. Having a recirculating system is the only way to have near instant hot water, and it is definitely worth having one. I would never build a house without one.
Our 26 year old 50 gallon tank heater still works great, which may partly be due to having a recirculating system that reduces sediment build up.
I wouldn’t mind going tankless, but don’t know if the cost/benefit is worth it. Especially since we have a recessed concrete silo, with a built-in drain, in case the tank ever leaked. It seems hard to justify the fuel savings, vs. the much higher cost for going tankless. Of course, if you tend to run out of hot water, tankless would make sense, or perhaps a larger tank heater.
If you run out often, it’s worth it. I had a teenage girl when I had one. She had a friend that love to take baths. They would sit in there for hours draining and filling the huge tub. A normal heater wouldn’t have been able to do it.
