DHC-E Tankless Electric Water Heaters
tankless electric water heaters # DHC-E models
These tankless electric water heaters feature:
  • Control Temperature Simply by Setting a Dial - Set the knob on the front cover and enjoy water temperatures between 86°F (30°C) and 125°F (52°C). Change the desired temperature at anytime. No purchase of a remote selector control is necessary. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.
  • Best Warranty in the Industry - Three years manufacturer's parts warranty.
  • Code Compliance Made Easy - The water temperature required by codes can simply be dialed in at the unit. The 100% accuracy of the water temperature is guaranteed by sophisticated electronics. No need to worry about mixing valves that go out of adjustment and wear out.
  • No Scalding - The electronic control system in the DHC-E does not allow the water temperature to go above 125°F (52°C), which eliminates the possibility that scalding may occur. On the other hand, 125°F (52°C) water is sufficiently hot for most uses.
  • Simple Design of Plumbing System - There is no need for a T & P valve, drain or mixing valve. The design of the hot water plumbing system gets very simple and straight forward due to the advances introduced with the DHC-E.
  • Sleek design fits in anywhere - Due to its small dimensions and attractive housing the DHC-E can be left unconcealed in many applications.
  • Seismic-Proof Construction - DHC-E is a tankless water heater system, and is thereby not subject to seismic code. There is no need for preventative construction, as required when using a bulky water storage heating system.
  • Superior, Reliable Performance - The DHC-E has two temperature sensors and one flow sensor which feed their readings into the unit's proprietary microprocessor control. Three heating elements are engaged in stages, achieving the temperature you desire. The DHC-E continually monitors the water temperature it produces. DHC-E Tankless Electric Water Heaters deliver instant hot water.
  • Ideal for restrooms or kitchenettes in an office or commercial/industrial setting: office buildings, gas stations, stores, schools, malls, hotels/motels, warehouses, restaurants, manufacturing facilities
  • In a residential setting, they are suited for the following applications: bathroom sinks, kitchen sinks, laundry areas, small cabins, boats/RVs

Note: Prior to ordering, please check/confirm the temperature rise limits of all brands of instant tankless water heaters to make certain that they will meet your needs. We guarantee that they will heat as the manufacturer states in the specifications, but instant heaters are not for every water-heating application and will only offer the heat rise stated for each model.



Frequently Asked Questions

Q. "How does the Water Heater Scale Inhibitor System prevent corrosion?"
A. It forms a thin protective layer on the inside of pipes and metal parts. This film or layer is microscopic in thickness and will not build up over time.

Q. "Will the Water Heater Scale Inhibitor System change the taste or odor of water?"
A. No. The active ingredient is colorless, tasteless, and odorless when used as recommended.

Q. "Will an instantaneous water heater save me money on my utility bills?"
A.In many applications you can see a savings. There are some variables that could reduce the amount you save. One example is you will not run out of hot water, so longer showers could cut into your savings. Also, the cost of electricity, propane and natural gas in your area will affect the amount of money saved. The higher the cost for the energy type used to heat your water, the quicker you can recover the higher initial cost of installing a tankless versus tank style water heater.

Positives:

    You will never run out of hot water. "You want an hour long shower? No problem!"
    Electric units can be installed at the point of use.
    You're not paying energy costs to heat water 24 hours a day.
    They're easy to install.
    Our electric units don't require a T&P valve (no tank!) - if code allows
    Installing a tankless water heater can indeed be a bonus to the environment (why should we choose wastefulness when we're talking about finite natural resources?)

Negatives:

    They all need a minimum flow rate & pressure to turn on.
    The faster water flows through them, the lower the temperature rise. So, if you expect to take a shower while the clothes washer is running, you will need to select a unit sized to your maximum hot water flow requirements. (Gas units generally handle this a little better than electric models)
    Electric units need heavy gauge wire. Example: the 9.5kw must have 8ga wire and a 50amp breaker.
    Gas units need a much larger, special flue pipe and larger gas supply than a conventional water heater.
    At times they can produce very hot water. It's easier to get scalded.
    Gas units are more complicated than a conventional water heater.
    With some brands, parts are hard to find (not a negative if you originally purchase from us, as we like to carry parts for the units that we sell).

Summary:
Tankless water heaters have their place. They're not "the answer" to every hot water need, but if they're used correctly they can be the solution to many of them.

Q. "What is siliphos?"
A. Siliphos is a water treatment compound; a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems and to prevent the build-up of scale in plumbing. It is made from a blend of food grade organic phosphates, and has been approved by the USDA for drinking water and all food applications. It is safe for ingestion by humans, animals, and plants, and does not build up in waste water.

Q. "What does it mean to have ANSI Certification for lead free plumbing products?"
A. Laws requiring plumbing products that come in to contact with drinking water to be essentially lead-free (0.25% weighted average) have been passed in California, Louisiana, Maryland, and Vermont. In order for companies to ship these plumbing products to locations in CA, LA, MD and VT, they must be ANSI certified lead free.

Q. "What is CA AB 1953, LA Act No. 362, MD HB 372, and VT S.152 and how is this different from previous low-lead legislation?"
A. The United States Environmental Protection Agency (EPA) regulates the amount of lead in drinking water under guidelines established in the Federal Safe Drinking Water Act (passed in 1974; amended in 1988 and 1996). This Act defines "lead-free" as not more than 8% lead in pipes and fixture fittings. PLEASE NOTE: Use of the term "lead-free" varies between the new legislation in CA (AB 1953), LA ( Act No. 362), MD (HB 372), and VT (S.152), and in the current Federal Safe Drinking Water Act requirements. In the new legislation for CA, LA, MD and VT only (as of Jan 2013), it will mean 0.25% or less (weighted average). Similar national legislation is scheduled to go into effect Jan 2014.

Q. "Is the Water Heater Scale Inhibitor System's active ingredient safe?"
A. Yes! All ingredients used are 100% pure food grade materials. They are approved by the USDA and meet purity requirements as a food additive by the World Health Organization.

Q. "What are the best reasons to install a Scale Inhibitor System?"
A. The system inhibits scale build-up and protects the piping from corrosion, which helps maintain efficiency and extends the life of the system.

Q. "What happens if you don't change cartridges often enough on the Scale Inhibitor System?"
A. The original water condition and problem will reappear. Hardness will begin to build up again, which you want to avoid.

Q. "Can I install this scale inhibitor upside down?"
A.This scale inhibitor can be installed in any direction with the filter pointing in any direction as long as the water flow direction is correct and the system has suitable pressure to function properly. Please note, the manufacturer recommends that the filter be supported if the Venturi tee is not installed horizontally with the filter outlet pointing downward. Also, if the Venturi tee is not installed horizontally with the filter outlet pointing downward, it may be more difficult to catch the remaining water in the line when replacing the cartridge. As always, please consult with a trusted local professional if you are at all unsure about correctly installing this scale inhibitor.
