I just had installed (yesterday) a Navien NPE-240A. After 24 hours I'd say it's doing great - but I sure would hope it's doing great after only 24 hours. LOL
Can someone explain how the internal tank and internal recirc actually works? (I don't have a recirc loop in the house - so it's not doing any external recirc.) The manual and product documentation only says it's purpose is to eliminate/reduce cold water sandwiching.
Does it keep the buffer tank hot all the time? Or does it only do the internal recirc if the buffer tank is hot and water is called for? I think the benefit in this scenario is some of the buffer is used to pre-heat the cold incoming.
It's the details of exactly what happens and under what scenarios is what I'm trying to understand.
Thanks.
