Can I get the Eccotemp NE3 45HI in the outdoor model NE3 45H outdoor ( natural gas model). If I can get it, can I get it sent to the Nanaimo store for pickup. What would the price be?

Asked by: Rick A
Unfortunately, only 45HI indoor is being sold to Canada due to the extreme temperature. Thank you!

Is this set up ok for propane or is it for natural gas hook up only?

Asked by: joey b
The 45 series model does have an option for Liquid Propane and Natural gas

Does this Eccotemp draw much power? My camp is serviced with solar panels so I like to control what electrical appliances I have. Also I should be able to reuse the power vent that I have on my existing BOSCH water heater?

Asked by: billie60
1. The amount of electric power would be negligible. 2. You could reuse the power vent if you can connect it so that it starts when the heater turns on and stops when the heater is off.

Can this be used to replace the gas hot water tank in a mobile home?

Asked by: rick88888
We purchased this unit for a double wide permanent home and its works perfectly. It takes less space than the old hot water tank. Be sure to vent your closet door for sufficient air floor.

what is needed to install it besides z vent kit?

Asked by: Roger212
Save 200$. Don't buy vent kit. I'm used gaz vent pipe. Same like to gas furnace. Gas furnace use 2 inch pipe, and nothing wrong,have more power, like this water heater.Just installed reduser 4 inches to 3 inches. Use fire rated calking to connect to heater.after turn 90' 3 inches, and 3 in. ABC black pipe 2 feet long to go outside home.to end pipe connect turn 90' ABC Whit simple drain cover. Just need install pipe a little down. For protect condensation water doesn't go inside home. In Europe we use metal flexible pipe, little stronger like to dryer. And nothing happened. What is special in North America ? I recommend this water heater for middle size home. I have full bathtub, and shower , 3 sinks and have enough hot water. Good luck!!

Eccotemp 45Hi-NG 6.8-GPM 140,000-BTU Indoor Natural Gas Tankless Water Heater is rated 3.0 out of 5 by 8.
Rated 1 out of 5 by from Avoid At ALL COSTS Tech Support is a Joke! Purchased November 2021. Has had issues basically since the beginning. Tech support is a joke! They have you contact them through their webpage. You have to wait for them to respond, which will only be a generic test and not help the issue at all. E1 code and we have jumped through the hoops of flame sensor is the issue, the board is the issue, our shower head is the issue, the screen on the sink faucet is the issue. Vent is clogged, needs descaling. THE WATER HEATER IS THE ISSUE. Everyone CANNOT be having the same issue code and the heater isnt the problem. THIS IS A POOR DESIGN. We luckily purchased the extended warranty, so we're done with the showers turning ice cold mid shower. DO BETTER ECCOTEMP. Don't bother asking us to contact you, we have tried on multiple occasions and your "help" is never actually help.

Rated 1 out of 5 by from Stay away from all Eccotemp products! Their products are poorly designed and their customer/tech support is horrible. We purchased a whole-house heater; it didn't work properly from the start and the tech support people are totally clueless and incompetent. The unit is clearly defective but they continue to offer repair suggestions which don't even apply to the unit's problem. When I asked for a warranty replacement, I was refused. They don't honor their warranties either. Stay away.

Rated 1 out of 5 by from Short life Unit lasted about 5 years before the copper, in the heat exchanger started to rot. They won't stand behind the warranty. Even after they said that the venting was correct.

Rated 5 out of 5 by from Works great Great water heater, works wonderful I have 3 faucet and never lost pressure from the hot water .
Date published: 2022-02-25
Rated 4 out of 5 by from Good product I installed this unit a few weeks ago. So far it works as it should. The only install issue I had with the unit was the hardware that comes with it. It showed up earlier than originally planned
Date published: 2021-11-28
Rated 5 out of 5 by from Very Good Water Heater I have had this water heater installed for close to a week now and I have to say it is a very good product at a good price. Was very easy to install.
Date published: 2020-09-22
Rated 3 out of 5 by from Great water heater ... When it works I have a hard time knowing how many stars to give. As the tile states, it works great when it works. Maybe 8 months into owning his water heater we started getting an E0 code. After talking to live chat about the issue they gave me a simple solution. Unplug the white sensor wire and plug it back in. Seemed simple enough but then after that we started getting an E1 code as well as the E0 code. Ok, that wasn't the worse of it. The front display stopped working. Couldn't turn it off or adjust the temperature up or down. So I emailed tech support. After doing more tested throughout the coarse of a few days and a few emails, the said he would send me out a replacement computer board under warranty but I had to pay a fully refundable deposit. Ok well that deposit was $100 but it's refundable. Got the new board and installed it. Well that didn't solve anything and my display still can't be changed. So hey tell me they will send out a new unit but I have to pay a fully refundable deposit for the replacement water heater which is $700 or I can ship back my water heater and be without a water heater all together until they get mine and they ship me out a replacement unit. Well i have a 9 month old baby and i can't be with out a water heater for 2 weeks. So i get the replacement water heater and get it install, which was paid for by me be cause I am not a plumber and can't pull permits to work with natural gas. Low and behold the new unit still is going me an E0 code but the display works and no E1 code. Ok, so i email tech support again and get told to remove all y aerators and inline filter systems that are connected to the water heater as these units don't work with them as they cause too much back pressure. Ok so I try that and still getting an E0 code. Email each support again but this time I am getting told that because i live in Canada and the temperature is below freezing that the water can be too cold and can cause air pockets which might be causing the code. I have grown quite tired of the games and the loss of money i have had to shell out under warranty. I have had to pay for the problem unit to be shipped back plus for a plumber to install the new unit. Has to be the worst warranty process ever and i still have an issue. In the end i have learned not to buy an Eccotemp product because Canadian winters are to cold for them or maybe it's the aerators, or maybe its the plumbing in my house has been there since it was built. Guess i won't ever find out
