Questions and Answers
1. Q. I know very little about tankless water heaters, so how can I be sure that I am getting the best tankless water heater?
This is by far the most important question to be answered.
The original tankless water heaters were developed to be used for a single fixture i.e. a single sink or shower. The temperature control wasn’t and isn’t suitable for multiple fixture use (i.e. a whole house) but a majority of electric tankless water heaters still use modified versions of this earliest technology.
Almost any company can find friends, employees, or business associates to provide testimonials for their product but it is very difficult to introduce new and innovative technology that earns the national and international recognition that will demonstrate to you that it is a mature and proven product.
2. Q. How do I select the right model of tankless water heater?
Refer to the APPLICATION SECTION on this web site.
3. Q. How much savings can I really enjoy from a tankless water heater?
That will depend on the type of heater you currently use and the cost of utilities in your area as well as where you are able to locate your heater. You can expect to enjoy from 30-50% savings from your tankless water heater over an electric tank heater.
These savings don’t come just from not heating and reheating the water in a tank, as that is only part of the costs. In addition you are not keeping water heated as hot as you do in a tank. Piping losses can easily equal the standby (loss through a tank when not used) losses.
When you locate a tankless closer to your major use areas you reduce the hot water you run before it reaches the fixture. That means less hot water left in the pipes that you had paid to heat wasted as it cools down after use.
You could actually save more, in many areas, from your tankless water heater over a gas tank heater which is located in your home. Gas prices have risen and it’s not uncommon to see the cost for heating water with a gas tank exceeding $300.
In addition a cost that is not discussed is the cost of the loss of air through the vent in your home. This is air you paid to heat or cool. It’s like leaving a window open all year. This cost can easily exceed $100 a year.
4. Q. Will one tankless water heater take care of my house with 3 bathrooms, etc?
The answer is yes, but you need to remember that you are installing a water heating system and not just a tank.
Not only your needs, but your ultimate expectations need to be considered. We provide all the design information that you would need in the Applications Section on our web site.

5. Q. What about hard water conditions? Do tankless water heaters really reduce the amount of mineral deposits?
Our tankless water heater can significantly reduce mineral deposits but you need to understand how and why. Since water acts like an insulator and doesn’t accept heat rapidly;
mineral deposits are caused by a heating element getting so hot that the heat can’t be transferred to the water fast enough and so boiling occurs around the heating elements sheath. That’s the same reason that you get deposits at the bottom of a pan you use to boil water. This condition is common in tank heaters when the element turns on full power and no water is flowing.
The tankless water heater is unique in its patented technology, which causes of each its elements at all times to share equally the heating load. This means that if you have four heating elements and need to use 25% of your heating capacity, the tankless water heater turns on each of the four elements at 25% of their heating capacity. (Like lights on a dimmer)
All other tankless heaters will turn at least One of the four elements on FULL POWER every time the heater is used. Obviously the tankless water heater elements are each individually operating cooler thus less chance for boiling.
Additional boiling can occur when the heater is turned off. When you turn the water off and the heater shuts off, the heating elements are still much hotter than the water (latent heat) and will add that heat to the water. In the case of the other tankless water heaters the element that was on FULL will be extremely HOT when the water is turned off and literally boil additional minerals out of the water virtually every time the heater is turned on and off.
6. Q. How does a flow switch help reduce mineral deposits?
Flow switches do not regulate temperature. They only turn on power circuits that allow the heating elements to be turned on when hot water use starts on and off when use stops.
The tankless water heater microprocessor control does not need or use any moving parts in the water path - including a flow switch. There is no flow switch that has been designed that can eliminate latent heat.
Unlike a tank, you can and should operate any tankless water heater at lower temperatures, but this won’t change the BOILING from tankless water heaters in which that single element will always be turned on FULL POWER at shut down.
7. Q. What makes your water heater so unique from other tankless water heaters?
WOW! The answer to that question could go on all day.
Briefly, our tankless water heater uses DuPont high performance engineering composite resins for its heating chambers to virtually eliminate scaling and provide very long service life.
The heater uses true microprocessor (computer control) power control containing the software for the use of its multi-patented control technology.
This control assures you the benefits of very precise temperature control for comfortable simultaneous use.
8. Q. What about safety, including scald protection?
The essence of the tankless water heater technology is temperature control.
No other heater of this type provides equal protection by virtue of the our heater's very precise control of temperature conditions.
Our heater operate your forever at lower safe temperatures that eliminate scald potential In addition, the our use a myriad of safety devices to further insure the safest of any electric water heater operation including relays, which completely disconnect power to the heating elements after use.
Dual safety high temperature limit switches, dual water level detection circuitry to prevent the heater from turning on when there is insufficient water level in the heater.
Our heaters provide leak detection that sounds an alarm in the event that there is water leaking from the plumbing attached to the unit.
9. Q. Why is your tankless water heater larger (15" X 15") than the other tankless/on demand electric water heaters I have seen?
We at discovered a long time ago that it was critically important to increase the amount of water in the tankless water heater as you increased the power.
This way we made sure that even with high power elements, much safer temperature control was accomplished. Most instant electric water heaters today started at lower power ratings.
They have increased the power but not the water capacity (buffer) in the heater. This increases the high temperature conditions that occur when the heater is turned off. The latent heat, still in the elements, is added to the extremely small quantity of water the was already hot.
10.Q. What about electrical requirements?
Your homes electrical service should typically be rated at 150 to 200amps. You check this by looking at the main circuit breaker in your electric panel box.
The electrical information is provided in the ELECTRICAL GUIDE.
If you do not have sufficient electrical service you may want to consider upgrading your electrical service or just using the EXTENDER model in line with your existing tank.
11.Q. My electrical service isn’t sufficient today for the largest whole house system. If I purchase a smaller EXTENDER model do I have to buy an additional tankless water heater later when I do upgrade my electrical service?
The EXTENDER will insure endless hot water and not require you to presently upgrade your service. (See information in the models Section)
IN THE FUTURE, HOWEVER, IF YOU UPGRADE YOUR SERVICE, YOU DON’T NEED TO BUY ANOTHER TANKLESS WATER HEATER, JUST UPGRADE THE EXTENDER. IT’S EASY AND INEXPENSIVE.
