Excel Pro: Modulating Technology
Tankless water heaters can be further divided into two categories according to their heating capability: "full on/full off" versus "modulating".
Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies.
Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit.
The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.

EXCEL TANKLESS WATER HEATER FAQ’s
Q. What is a tankless water heater?
A. Most people in North America currently use a storage tank water heater to provide hot water in their homes. A storage tank water heater wastes energy by keeping water hot 24 hours a day, even while you’re at work or sleeping.
A tankless water heater, on the other hand, does not store hot water. It heats the water instantly as you use it.
Q. How can a tankless water heater heat water instantly?
A. When you open a faucet, the flow of the water triggers the heater to turn on. Whether you use gas or electricity, the powerful gas burners will turn on, rapidly heating the water as it passes through the unit. The water is heated instantly, and the time it takes to obtain hot water is directly related to the distance the hot water has to travel from the water heater to where hot water is being used. The burners or elements then shut down when you shut off the hot water. The energy that is consumed is only for the hot water that is being used.
Q. What are the advantages of using a tankless water heater?
A. Because a tankless water heater turns on when you open a hot water faucet and turns off when you close the faucet, the energy that is consumed is only for the hot water that is being used. Since there is no storage of water, and thus no constant heating and re-heating of stored water, you’re not wasting energy heating water when you don’t need it, such as when you’re sleeping or not at home. This energy savings translates to dollar savings for you and reduced impact on our environment. Furthermore, since a tankless water heater heats the water as you use it, you can have an endless supply of hot water, provided you size the unit appropriately
Q. How much money can I save?
A. Depending on which model of tankless water heater you purchase, and what size storage tank you have now, and if it runs on gas or electricity, you could save anywhere from 5% to 69% off your hot water heating bill. How? Most homes use hot water for a cumulative total of about one hour per day, yet they typically keep 40 or 50 gallons (oftentimes more) of water hot 24 hours a day. Having a system that eliminates the storage and heats water only as you use it can dramatically reduce your energy consumption.
Q. Can it really provide an endless supply of hot water?
A. Yes. Because storage tank water heaters store a finite amount of water, when that amount is used up your shower goes cold and you have to wait for the heater to heat the water back up (this is known as recovery time). Because a tankless water heater heats the water as it passes through the heater, you can never run out, provided flow limitations are not exceeded
Q. Are there other benefits of a tankless water heater?
A. There are many advantages of having a tankless water heater in your home. Besides the money savings, endless hot water and smaller impact on the environment, a tankless water heater:
Q. Will I still get the hot shower I’m used to now?
A. Yes, provided you buy the right tankless heater for you . Tankless water heaters are able to function at a variety of temperatures that you can choose, and can produce hot water at the same flow rate as your standard single-headed shower provides now.
Q. Will one tankless water heater service my entire house?
A. Yes. You must choose the proper model to suit your home’s hot water needs, which is based upon the maximum flow of hot water you need at any one time . We sell tankless water heaters that are capable of handling one shower at a time and others that can sustain a maximum of three showers operating at the same time.
Q. What if I have very hard water?
A. Since tankless water heaters do not store hot water, minerals have less of an opportunity to settle out of the water column and build up inside the heat exchanger. Additionally, the flow of hot water through the coiled heat exchanger flushes the product each time hot water is used. The use of a water softener is fine with a tankless water heater, and is recommended if you commonly experience hard water problems in your home.
Q. What limitations do tankless water heaters have?
A. Because this type of water heater heats the water as you use it, the volume of hot water that it can deliver is directly correlated to the amount of its energy input. The bigger the burners or heating elements in the unit, the higher the volume of hot water that it can deliver. Today tankless water heaters come in various sizes to suit most homes’ needs. Even if you need to be operating multiple showers at once, tankless water heaters can keep up
Q. How do I properly size a tankless water heater for my home?
A. You need to choose the model that can deliver the volume of hot water to meet your needs. The best method for sizing this type of water heater is to know how many showers each model can run simultaneously. We have models that can run either one or two showers at a time. And remember, a tankless water heater can deliver endless hot water, shower after shower.
Q. Can I fill a hot tub with a tankless water heater?
A. Yes. Because tankless water heaters provide an endless supply of hot water, you can fill a tub of any size. It is only a question of time, meaning that our larger units can fill a tub faster than our smaller units. Keep in mind that some tubs draw water at high flow rates, so it may be necessary to limit the flow so that the tankless water heater can adequately heat the water that is being called for.
Q. Is this a new technology?
A. No. Europe, Asia and South America, where energy costs are more expensive than here in North America, have been using tankless water heaters for 75 years. ExcelAmerica has been selling and supporting tankless water heaters in the United States since 2002. However, Americans are now more energy conscious and are aware of the carbon footprint of their appliances and are just now learning of this technology and its benefits
Heat exchangers are devices that transfer heat in order to achieve desired heating or cooling.
An important design aspect of heat exchanger technology is the selection of Pure Copper (Oxygen Free) to conduct and transfer heat fast and efficiently.
Pure Oxygen Free Copper has many desirable properties for thermally efficient and durable heat exchangers. First and foremost, copper is an excellent conductor of heat. This means that copper's high thermal conductivity allows heat to pass through it quickly. Other desirable properties of copper in heat exchangers include its corrosion resistance, biofouling resistance, maximum allowable stress and internal pressure, creep rupture strength, fatigue strength, hardness, thermal expansion, specific heat, antimicrobial properties, tensile strength, yield strength, high melting point, alloyability, ease of fabrication, and ease of joining.
The combination of these properties enable copper to be specified for heat exchangers in industrial facilities, HVAC systems, vehicular coolers and radiators, and as heat sinks to cool computers, disk drives, televisions, computer monitors, and other electronic equipment. Copper is also incorporated into the bottoms of high-quality cookware because the metal conducts heat quickly and distributes it evenly.
Non-copper based heat exchangers or Regular Copper with tin bath cheaper versions are also available in the market , they are less efficient and have a short life.
Pure copper heat exchanger are customarily used only by top of the line tankless gas water heater manufacturers like Rinnai, Takagi, Rheem , Noritz and this new line of Excel Water Heaters
