  • I think I have the heater settings figured out. With a little patience, it now works great and am very happy with it.
This water heater has great high end features of far more expensive versions. It is very well made and once the knobs are set for your particular needs, it works consistently. The 'water temperature' adjustment knob could use a better description. From tinkering with it, I concluded the 'water temperature' knob is really a flow rate adjuster. A higher 'water temperature' setting, makes the water heater turn on at lower flow rates (lower demand) but also limits the flow capacity. It seems to behave like a restricter, that increases the flow velocity which then triggers the heater to turn on, but like a restrictor, it also limits the maximum water flow rate. Turn the 'water temp' to a much lower setting and the heater flows a lot more hot water but also needs more water 'demand' (two small faucets together will do it) to trigger the heater to turn on. The gas knob simply adjusts the size of the flame. So with lower water flows (higher 'water temperature' knob setting) you will want a smaller flame to keep the heater from shutting off due to overheating from the lower water flow. So to clarify: A Higher 'water temperature' knob setting = more 'turn on' sensitivity but a lower maximum water flow rate. A Lower 'water temperature' knob setting = less 'turn on' sensitivity but a higher maximum water flow rate. Once you set the right 'sensitivity to flow' for your needs, then simply set the gas knob to a good water temp. I would err on the cooler side (lower gas knob setting) to keep the heater from over heating and shutting off. But if you have higher water flow setting (lower 'water temperature' knob position) the gas can be set a little higher. In order to warm the increased water flow. I hope this helps someone who was not considering this heater. It really works great, it simply needs a little patience to be set to your speciific water heat and flow needs. ... show more

  • Installation was easy with everything provided for venting
I have this installed in my detached garage/shop. It serves my need perfectly. I'm not wasting energy keeping water hot in a low use environment On-Demand is ideal for a Home shop. Installation was easy with everything provided for venting. (SS Piping could have longer) gas and water hookups standard. I'm using PEX water line with no issues. Operation of the heater has been trouble free as far as the heater goes. Operation and trouble for the operator is a whole other story. I fussed with the gas and water controls until is was blue faced with anger and frustration. I couldn't get a consistent comfortable temp, use the cold waster and the heater cuts off, turning knobs every witch way getting more and more confused wondering what i had bought. Sometimes you just have to walk away and not think to much or to hard. I didn't go near the heater for a few days. it was hard to resist not trying to adjust the temp to one liking. Walking away did the trick . Spending a life time with a tank water you mix your hot and cold water at the faucet to get your desired water temp. being this a base model for small applications this mixing is done at the heater and is now a set temp of your liking. One just uses the hot water knob to turn the heater on or off. The water temp that flows out will be what temp you configured at the tank. no reason to add cold to hot or hot to cold to get the right temp as you would do with a tank heater. My frustration was over with, I also canceled my appointment with a shrink as I thought I was loosing my mind. This a a no frills unit You have one temp from any of your faucets or shower heads with. You cant start out with a warm shower and slowly increase the amount of heat, You only get the temp that you set at the heater. for my situation being a garage/shop this works great. If my situation was having this model in my home it would not work to small and basic with just the one temp. Sometimes a HOT shower is in order Now that all is focus this is a trouble free, efficient, instant on demand heater I very happy with.. EcoTemp's owners manual is lacking in setup and operation instruction not offering a clear understanding of the heater single temp operation. they are also vague in other parts.This is common with products that come from Asia because translation is such a problem Detailed explanation and / or Q & A is not even attempted. If one temp for all doesn't work for you I'm sure their higher end models have at the faucet mixing or hot and cold. This heater is a great bargain if your needs fit this heater. it's well made and does what its supposed to do each time the hot water faucet is turned on delivering Eco friendly hot H2O. Update 5/25/2016 I'm back to nothing but anger and frustration with this heater!! I since installed a bathroom. Back to not being able to maintain a consistent water temp. In the beginning the heater was configured to my utility sink and it's natural flow rate. Adding a small sink for thje bathroom it's flow rate is much less than the utility. when attempting to use the bath sink anything can and does happen at each use. wild temp spikes or heater shut off. to get the heater to work in the new bathroom sink i first have to turn on the the utility sink hot water then go to the bathroom sink and slowly feed off of the hot running to the utility sink. why didn;t i just wash up at the utility in the first place. Says it all about this crap water heater. what a waist of hard earned money. Now I have to spend more I don;t have. ... show more

  • Dont Know wether to rate 0 or 5
The price was lowest compared to other brands. As others have said, it requires apx 1.5 gpm to start working, there are adjustments inside the unit to modify the diaphragm & micro-switch to start the unit with less GPM's going thru it. I modified the settings and micro switch sensitivity but will keep it functional as the present setup is a safety concern and it has a pretty fool proof logic.. simple. Next is to set all of the fawcetts to flow about the same which are on the water line so the unit can detect flow and all of the fawcetts have the same or desired heat..shower is my main concern with a low flow head.. (be cautious of the low flow, it may not trigger the unit to start) the unit is user set as to heat vs flow, it is not an automatic proportional design so some trial and error is involved. With that done, looking at the system it works very well once set, occasionally i have to turn off the fawcett and re open it if somehow it did not fire up, minor inconvenience. I think the 600 buck + units may start at a lower flowrate and proportionally regulate the heat vs flowrate to the set temp .. this is better when there are more fawcetts and when they are used at the same time thus avoiding the cold momentarily shower or when the flowrate is changed threw the Ecotemp just before it cuts off or is exceeded to heat vs flow, it gets hotter or cooler depending on load, this is good and bad .. if i want a bit more heat i cut back the flow and hope i am just before cut off sometimes it just right sometimes i get cold at the end.. So i do not know whether to rate this a 0 or 5.. If i had known this i would have gotten the 600 + buck unit but im happy enough with the Ecotemp knowing i can modify the guts for other applications if i need to and the price was a good deal. ... show more
