Right now, what you are getting is the opportunity to buy this fabulous leading edge technology Excel gas water heater at much  less than the manufacturers suggested retail price $ 399.

ODS Vent-Free technology:

ODS is to gas what a circuit breaker is to electricity.

More Info on the Oxygen detection safety-pilot (ODS)

ODS technology originated in Europe, and has been widely used in European gas heating appliances for more than 45 years with an outstanding record of safety and then adopted by U.S. manufacturers for all vent-free gas products such as logsets and camper heaters.

Consumer Product Safety Commission (CPSC) accident/incident data accumulated since 1980 show an unparalleled 100% safety record on ODS-equipped vent-free gas heating appliances. Industry engineers say the ODS pilot is to gas what a circuit breaker is to electricity.


If low levels of oxygen are detected **, by the ODS system, the flame extinguishes. The loss of flame causes the thermocouple to cool. This cooling sends a signal, which causes the gas valve to return to its normally closed position, thus turning off the fuel supply to the appliance. The unit will not operate until the living space is properly ventilated and adequate oxygen is introduced, and the appliance is manually restarted.

** Normal levels in the atmosphere is 20% oxygen , low levels of oxygen are 17% to 18%, .

It also comes with a redundant safety feature ( 20 minute shutoff timer ).    The unit will automatically shut off after working for 20 minutes .

NOTE: The ODS is not a standing pilot , it is only "on" when the appliance is working.

Igniter Electrode: With remarkable electronic technology that requires NO STANDING PILOT  the outstanding Excel heater saves up to 25% in gas consumption when compared to older technology lighted pilot lighted units.

In case of a power outage or no power supply such as in RV'S , campsites, boats and sailboats, you can still enjoy your hot water at home as it uses (2) size “D” batteries to ignite the electronic spark module.

RULE OF THE THUMB PERFORMANCE CRITERIA 

 

This unit is suitable for a Multiple Points of Use, for an entire home- with 2 1/2 bath.   However, no more than one point of use at a time is recommended.

Recommended  for  incoming cold water temperature above 50°F, however it can take lower incoming temperatures down to 40°F by reducing water flowrate (control knob can be adjusted to less water flow).

This amazing instant water heater is designed for one point of use at a time and it can be connected to the existing hot water piping. It is Ideal for small apartments, flats, hunting cabins and small homes as well as boats, sailboats, campers, RV’s  and mobile homes. 

Infinite applications can be found for the extraordinary Excel tankless water heater. Our customers also use them for washing stalls, horse trailers,  de-icing cars in the winter, outdoor camping,  RV´s,  Motels,  small roadside restaurants and other situations where endless and economical water heating is required. 

* LOW PRESSURE STARTUP TECHNOLOGY

 

The Excel Low Pressure Startup unit is outfitted with a magnetic water flow sensor , that allows the unit to work at low water pressure, especially those found in rural areas , RV's and Boats. 

All other tankless gas water heaters rely on the outdated rubber diaphragm scheme , that pushes  a pin that actuates a microswitch.

Pressures of the order of 30 psi are needed to move the rubber diaphragm on other older and cheaper units.

 

PURE COPPER (OXYGEN FREE ) HEAT EXCHANGER

 

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.[6] 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 2018 line of Excel Water Heaters.
