Installation was easy, technician had no significant issues. 6.8 unit supplies enough hot water to a 3,100 sq. ft. home with 3 bathrooms within minutes. Whether there will be any cost savings on the gas bill remains to be seen.

Relatively easy to install (once you have all the connectors, pipe/pex, shut offs, etc.) Longer to get the parts than to install it. One big thing is that it does not come with a pressure relief valve and nobody carries them in stock so you have to order. Best to do this while waiting for the unit to arrive. Might have to play with the temp control if your water pressure to the house is not strong.

Hi Joel, your response didn't answer my question. My question requires a "YES" or "NO" response to be satisfied. Can this be exhausted out a conventional 100 year old roof top chimney?

Asked by: TheDude
No, it cannot.

Can this be exhausted out a conventional 100 year old roof top chimney?

Asked by: TheDude
The Eccotemp requires a Category III chimney such as the Z-Vent stainless kits sold on the Home Depot website.

Why can't I vent this through my existing chimney like a regular tank?

Asked by: lori
After talking to the gas fitter he explained that when the tank turns on (for the short amount that it is on for) it uses more gas than a regular tank water heater would in that time frame and therefore the exhaust is hotter. The plastic venting on tank water heaters just isn't rated to deal with the heat difference. Or at least that's part of it

Home Depot is this correct... “Z-flex” 4” horizontal vent kit (or vertical) is the correct vent kit for installation in Saskatchewan, Canada?

Asked by: Genni55
The Z-flex vent kits are certified and approved on a national level in Canada but to ensure that the product is up to code in your area, it's important to verify with a regional registered gas installer.
