The Excel heater saves energy and water by instantly delivering hot water upon opening the hot water tap. Its unique and beautiful design will lavishly decorate your kitchen or laundry room.
What is Vent-Free? A Vent-Free appliance can be installed inside and does not require cumbersome and costly installation of flues and ductwork because it is outfitted with state of the art ODS (Oxygen Depletion Safety shutoff device).
Electronic Ignition: no standing pilot required.
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, you can still enjoy your hot water at home because it uses (2) size ?D? batteries to ignite the electronic spark module.
Compact Exquisite Design:
The Excel Gas Water Heater’s compact design, the size of a 18 flat panel monitor, takes up reduced space and attractively decorate modern living spaces.
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, campers, RV?s and mobile homes.
It delivers over 96 gallons of hot water an hour with a 45 degree rise in temperature. This means that if your tap water is at 65 °F, it will instantly deliver 96 gallons of hot water an hour of water at 110 °F.
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 and water pressure is available at 10Psi.
Perfect for Sailboats and Cabin Cruisers with active ventilation systems in place.
Used in Australia, Europe and Japan for many years, this technology is now revolutionizing the way we heat water in America.
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.
How the ODS works:
The ODS system consists of three main components:
Thermocouple: A device consisting of two pieces of dissimilar metals joined together at one end (hot junction). When the hot junction is heated, the thermocouple produces DC voltage to the other end. It powers thermoelectric gas valves and when used is a safety feature on gas hearth products.
Pilot Burner: A precisely designed, oxygen sensitive pilot burner that regulates flame characteristics; A thermocouple positioned in the mantle of the pilot flame; and a safety shut-off valve operated by means of a “normally closed” soleniod.
The pilot is designed to be stable within a very narrow operating range. The thermocouple responds to changes in the pilot flame characteristics and, when heated, generates a signal, which keeps the gas supply valve in the open position.
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.
It?s tamper-proof, every ODS system contains a precision orifice made of an industrial Rubi. This orifice is designed to disintegrate with any attempt at drilling it out to enlarge the pilot flame.
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 (NOT INCLUDED) to ignite the electronic spark module.

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.
