Questions & Answers

Is this Water heater vented horizontally, through a wall, or can it be vented through my existing...

Is this Water heater vented horizontally, through a wall, or can it be vented through my existing pipe through the roof?
Asked by: Peter
I just had the bad experience that it has to be installed according to instructions with a horizontal vent through the wall and slanting downward due to water condensation. Forget using the old roof vent. Also stainless steel pipe, not galvanized or PVC. And new gas line must be 3/4" and has to be upgraded.. Expensive...

I have a cabin in Michigan. I drain the water several times a winter, how hard is it to winterize it each time.
Asked by: randy
Very easy If you get the add kit. Just open the flush kit and drain. Unplug the power first.

Eccotemp 45HI-NG 6.8 GPM WholeHome/Residential 140,000 BTU CSA Approved Natural Gas Indoor Tankless Water Heater is rated 3.2 out of 5 by 72.

Just days after hook up an error code appears. I repeatedly sent pictures and videos of a leak inside the unite from a copper elbow. The only option given me was to pay $127 to have it shipped 700 miles to be looked at. It was returned with a replaced electrical component but the leak was not touched yet a worse leak from torn O' ring when technician replaced fitting. In a call I was told that no leak could be found despite the images and videos sent but I was sent new O'ring to replace myself. The original was an obvious leak whenever water ran through the unit. I was sent a 2-part epoxy product that cannot be applied without great difficulty and could not contain the leak. Disabled with fixed income and a family I have been saving to buy a new water heater for 16 months now with cold water for daily use. This is my best recommendation!

Problem the installer came to give me an estimate and said I had to re-work the exaust piping out the wall instead with the current flue through the roof. I had to get steel piping because the heat was greater for the way this works, instead of PVC pipe with other appliances. This made it very expensive. The gas line also had to be changed from 1/2 to 3/4 because it cousumes more fuel when it runs making hot water. To me the savings was a wash but the install was too expensive. Works well if you get new construction....

Rated 1 out of 5 by from Ughh... Won't work with low flow faucets Just installed unit yesterday only to find that I don't have appropriate gpm flow rate (1.1) at sink for the unit to turn on. Recently installed a fairly standard low flow faucet, that will not work with the unit. Basically you have to have any faucet opened all the way to turn the unit on, otherwise, just icy water. If you live any where that you are concerned with water usage, do not buy this one, it won't turn on with low flow faucets at shower or sink, and you can't turn the water down a little to conserve water. It would seem easy to make the unit turn on with a low flow rate, but nothing is adjustable, have to remove unit and reinstall a different one, looking at the rheem, for $600 that turns on at .4gpm compared to this one's 1.1 gpm requirement.
