"How does the staged turn on work?"
Staged turn on models only use the heating modules needed to produce the desired output temperature.
"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.
"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 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.
"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 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.
"The Eemax tankless water heaters info 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 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.
