Frequently Asked Questions
Q. "Why do I need to fill out an order acknowledgment form when purchasing one of the Triple Module tankless water heater?"
A. The manufacturer requires us to include this form with our shipment request so that they will have verification ("proof") on-file that they manufactured and shipped the correct heater. If you are ordering a 3-phase Eemax heater, you will need to print and fill out the order acknowldgement form (found below the ordering table of the model you want), and then fax or mail it to us. Special 3-phase heaters are manufactured-to-order and most residences are not wired for three phase configurations. Therefore, these special three phase are non returnable. The manufacturer will not ship your water heater until this form is received.
Q. "Why is the max flow lower for the staged turn on?"
A.The heating modules are set up differently to accommodate different flow rates.
Q. "How does the staged turn on work?"
A. Staged turn on models only use the heating modules needed to produce the desired output temperature.
Q. "Are all Eemax tankless water heaters designed to be hardwired?"
A.Yes, every tankless water heater by Eemax is supposed to be hardwired when it's installed.
Q. "Does the kW listed under each model represent the amount of energy they use if all the heating elements are on?"
A. Yes, the specification for kilowatt usage for all models show the maximum wattage with all heating elements on.
Q. "Eemax instant heaters specify the 'temperature rise' based on the GPM flow; what do you mean by this?"
A. Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.
Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be "essentially lead free" (less than 0.25% weighted average). For further information about how the law determines what is "lead free", rules regarding which plumbing products must be "lead free", and who these laws will affect, please view our page.
Q. "Can I install these tankless water heaters in my attic?"
A.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.
