Low rates and easiest to calculate/understand shipping/handling for tankless water heaters
"Why is the max flow lower for the staged turn on?"
The heating modules
are set up differently to accommodate different flow rates.
"What's the difference between the parallel turn on and the staged turn on?"
The parallel turn on will give you a higher maximum flow rate, and it needs a higher flow rate to turn on than the staged turn on.
The staged turn on will turn on with a lower flow rate, and it handles a lower maximum flow rate than the parallel turn on.
"How does the staged turn on work?"
Staged turn on models only use the heating modules needed to produce the desired output temperature.
"Does the kW listed under each model represent the amount of energy they use if all the heating elements are on?"
Yes, the specification for kilowatt usage for all models show the maximum wattage with all heating elements on.
"Are the single point, flow controlled and MARINE/RV water heaters field adjustable?"
No, only water heaters that say they are thermostatic allow you to adjust the temperature of the water heater.
"When it says "turns on with at least .5 or .7 GPM" how do I know which water heaters turn on at .5GPM or.7GPM?"
The water heaters that have a temperature listed under the .5GPM flow column are the water heaters that will turn on with only .5GPM. If there is no temperature listed in the .5GPM column, then the water heater starts when there is .7GPM flow.
"Are all Eemax tankless water heaters designed to be hardwired?"
Yes, every tankless water heater by Eemax is supposed to be hardwired when it's installed.
"Why does it say the water heater can have 3/8" or 1/2" pipe compression fittings?"
The water heater comes with an adapter so the pipe compression fittings can be used as 3/8" or 1/2" pipe.
"Why does it say the water heater can have a top or rear entry electric?"
There are holes made in the top and the rear so the customer can set up the tankless water heater as a top entry or a rear entry electric. The choice is left up to the customer when they install the water heater.
"Why does it say the water heater can have a bottom or rear entry electric?"
There are holes made in the bottom and the rear so the customer can set up the tankless water heater as a bottom entry or a rear entry electric. The choice is left up to the customer when they install the water heater.
"Your products specify the 'temp. rise' based on the GPM flow; what do you mean by this?"
Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.
"Will an instantaneous water heater save me money on my utility bills?"
Yes, in most applications you will see a savings. There are some variables that could reduce the amount you save. One example is you will not run out of hot water, so longer showers could cut into your savings. Also, the cost of electricity, propane and natural gas in your area will affect the amount of money saved. The higher the cost for the energy type used to heat your water, the quicker you will recover the higher initial cost of installing a tankless versus tank style water heater.
Positives:
You will never run out of hot water. "You want an hour long shower? No problem!"
Electric units can be installed at the point of use.
You're not paying energy costs to heat water 24 hours a day.
They're easy to install.
Our electric units don't require a T&P valve. (No tank!)
Installing a tankless water heater will indeed
be a bonus to the environment (why should we choose wastefulness when
we're talking about finite natural resources)?
Negatives:
They all need a minimum flow rate & pressure to turn on.
The faster water flows through them, the lower the temperature rise. So,if you expect to take a shower while the clothes washer is running, you will need to select a unit sized to your hot water flow requirements. (Gas units handle this a little better than electric models)
Electric units need heavy gauge wire. Example: the 9.5kw must have 8ga wire and a 50amp breaker.
Gas units need a much larger, special flue pipe and larger gas supply than a conventional water heater.
At times they can produce very hot water. It's easier to get scalded.
Gas units are more complicated than a conventional water heater.
With some brands, parts are hard to find (not a negative if you originally purchase from us, as we like to carry parts for the units that we sell).
Summary:
Tankless water heaters have their place. They're not "the answer" to every hot water need, but if they're used correctly they can be the solution to many of them.
"I am looking for an electric tankless water heater having less than 15 amps 120volt. Do you offer any?"
Unfortunately low amperage/wattage doesn't produce much "instant" heat (no matter what). The elements that we offer are almost 100% efficient (meaning
that almost all of the heat that an electric element produces is already transferred into the water).
You simply can't buy any brand (anywhere) of tankless water heater that uses less than 15 amps at 110volts that will give you much of a heat rise. We wish it possible as we would be able to sell many more
electric tankless water heaters. If you only have 110-120 volts you might wish to consider using a small water heater instead of a tankless heater. Just click here to see those.
"Can I install these tankless water heaters in my attic?"
Without seeing all of your plumbing piping, etc. it is difficult for us to answer with a
straight "yes" or "no." One must be sure that a possible water siphoning condition can not be created as these fantastic electric tankless
water heaters can not have air in the lines. Water siphoning out of any brand of electric tankless water heater might damage the heater or element
when the element is on and there is no water (or not enough water) in the lines. Air should not be touching the elements.
"Will the Hot Water Heater Scale Inhibitor System change the taste or odor of water?"
No. The active ingredient is colorless, tasteless, and odorless when used as recommended.
"Is the Hot Water Heater Scale Inhibitor System's active ingredient safe?"
Yes! All ingredients used are 100% pure food grade materials. They are
approved by the USDA and meet purity requirements as a food additive by the World Health Organization.
"What are the best reasons to install a Scale Inhibitor System?"
The system inhibits scale build-up and protects the piping from corrosion, which helps maintain efficiency and extends the life of the system.
"How does the Hot Water Heater Scale Inhibitor System prevent corrosion?"
It forms a thin protective layer on the inside of pipes and metal parts. This film or layer is microscopic in thickness and will not build up over time.
"What happens if you don't change cartridges often enough on the Scale Inhibitor System?"
The original water condition and problem will reappear. Hardness will begin
to build up again, which you want to avoid.
Help save our environment by saving energy.
Stand-by heat loss wastes a LOT of energy.
Installing tankless water heaters saves
energy, as well as your pocket book in the
long run. Think future! Think green.
Think Tankless!
