Your review: Replaced an older EEmax tankless heater that was 10 years old. other than the water supply and discharge fittings being a different size. I was able to stop into the local hardware co and get a set of Shark Bite reducers that worked great.
This heater makes no noise and does not make the lights flutter when in operation like the earlier model.
Pros: it is what the said it would be great for our camp in Maine. Smooth swap out from old to new when you have what you need on hand.
Cons: installation manual should have better information on pipe sizes. The old EEMAx guide was detailed.
