Advantages of This Water Heater
Besides instant hot water, even faster hot water delivery than a tankless water heater, other advantages of this invention are low cost, longevity, and zero maintenance.
To make the installation faster and simpler, the tank assembly comes with its power cord attached, and both water inlet and outlet connector hoses. The
installation should take less than 10 minutes.


1. The tank is made of a strong non-corrosive fiberglass reinforced plastic. The tank inlet and outlet connections are also of non-corrosive plastic. Thus, no corrosion can ever occur. 

2. The heating element is not inside the tank immersed in water, but is external of the tank, and is essentially a sealed heating blanket wrapped around the tank. Since the heating element is external of the tank, and not immersed in water, the element is never subjected to the galvanic corrosion that all other water heaters experience.

3. The design of the heating element prevents overheating even if the tank has no water in it.


1. The design of this water heater requires no maintenance over its entire life. The tank itself is a corrosion proof tank housing.  Since the heating element is external to the tank, the heating element cannot experience the electrolysis that every tank with an immersible heating elements experiences. 

2. Whereas all electric water heaters with immersible heating elements require an anode rod to reduce corrosion induced tank failure, or heating element failure, or inlet and outlet connection failure, or the anode rod itself’s failure, it is a certainty that that a water heater with an immersible heating element will require maintenance and flushing, plus, at some point the anode rod will need to be replaced with a new anode rod.

3. Water hardness is always a serious problem with conventional, tankless, and recirculation systems, and so they require maintenance. But with this water heater water hardness is not an issue at all.

Here is a quote from a well known conventional water heater manufacturer.

“Properly maintained, your water heater will provide years of dependable trouble-free service. It is suggested that a routine preventive maintenance program be established and followed by the user. 
It is further recommended that a periodic inspection of the operating controls, heating elements and wiring should be made by service personnel qualified in electric appliance repair.
A water heater’s tank can act as a settling basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. It is suggested that a few quarts/liters of water be drained from the water heater’s tank every month to clean the tank of these deposits.”

Warranties on today’s currently marketed hot water heaters vary from 1 year to 12 years life on leakage, but only 1 to 6 years on switches, elements, and anode rods.

We know that a kitchen sink requires a reasonable flow of hot water, something that a 120 volt tankless water heater cannot deliver. Even a 240 volt tankless won't work at a kitchen sink unless it is extremely high power. Here's a wild example of how much power you have to have.

                                                                            Tankless Water Temperature Calculation
                                                                 GPH (gallons per hour) = KW*400/(temperature rise in °F)

                                                                                               volts   240
                                                                                                amps   50
                                                                                          watts = 12000
                                                                                             = Kwh     12
                                                                                      Kw * 400 =  4800
                                                                                temperature rise = 65°
                                                                                              gph  =   73.8
                                                                maximum flowrate  gpm   =    1.23

It is doubtful anyone would want a high amperage, high cost 240 unit under their kitchen sink. Your main circuit breaker may not be able to handle that. Compare this to the Homewater which delivers 1.5 gpm.

The homewater is a low wattage heater. Its water input comes from the home's 50 gallon conventional tank. Because the heating element is wrapped around the outside of the tank, the homewater heats the mass of tank and water, and then mixes hot water in its tank with any cooler water arriving through lengthy plumbing to kitchen.

Lastly,it is calculated that the payback on a tankless water heater might be 22 years, and the payback on the Homewater is under 4 years.
