Tankless Water Heater- PFAS, BPA, etc

[Mugatu300]

Hello all, interested in the Navien NPE-240A2. Tried contacting them to no avail. It looks like there are a lot of plastic components on the inside of the unit. Does anyone know if any of these come into contact with water and if they contain: PFAS, PVC, Phthalates, BPA, or microban style antimicrobials? Thank you.

If so, would a tank style water heater be considered less plasticky or "toxic"?

atmospheric inhalation of the few plastic fittings in the waterway is extremely minimal.

But it is possible correct? And there are plastic components that come into contact with the water as it traverses through the unit?

I'm not sure which would be considered more plastic: tankless with all its parts or a tanked system with the dip tube...

I just looked at the parts diagram and a lot of the adapters are black plastic. Just a bit scary to think about super hot water passing through all this plastic- does anything leech out into the water? I know I'm not drinking hot water but still ingest some whether its shower, bath, washing face, washing dishes, brushing teeth, washing produce, etc. For example, look at this part:

Most of the water way is plastic, but the parts are like the plastic pex fittings. Similar material. It doesn't (or at least isn't supposed to) leach into the water.

PVC is the only material that I know of that has this problem and it's only a problem if you heat the water. Pvc isn't allowed into hot water piping for this reason.

I'm not sure what type of water you drink, but there's likely more contaminates from other sources. The water heater is probably the least worrysome when it comes to this.

Yes, i understand its not totally avoidable but we are trying our best and hyper sensitive now that we have some little ones. Thats also why we dont have any PEX in the house after some studies came out showing chemical leaching. Copper only.

There have been recent studies that found more microplastics in glass than in plastic bottles. It seems like it is practically unavoidable at this point...you shouldn't be drinking the hot water anyway so exposure to any if present would be minimal.

I hear you, just again we are kinda OCD now with the infant. We've been seeing articles about those microplastics being absorbed through skin so we got worried about giving baby a bath lol.

Best things you can do is let kids play in the mud and eat their buggers. It boosts their immune system. All these germo-phobes with their alcohol sprays and masks are the first ones to get sick. Your body needs good and bad bacteria's.

New research is mouthwash is a no-no now. Kills all the beneficial germs in the mouth. Turn the TV off and enjoy life people.
