Bosch Powerstream Pro Tankless

Electric Water Heaters


The Powerstream Pro Tankless point-of-use electric water heaters from Bosch are an innovative solution to heating water at the source. With many to choose from, you can customize your water-heating usage. Go tankless with a Powerstream Pro Tankless water heater from Bosch.

Point-Of-Use Electric Tankless Model # RP12PT
Point-Of-Use Electric Tankless Model # RP12PT
Features:

Water is heated as it flows through the Powerstream, so you will never run out of hot water.

The Powerstream Pro is ideal for 1 sink at a time & is the perfect solution for home and office sinks.

Powerstream Pro is a premium water heating product that uses a solid copper heat exchanger and copper sheathed heating elements to instantly heat water. A durable plastic housing protects the interior components.

Because of the safety switch that these heaters have, the elements on these heaters will not burn out if they are "dry-fired" (i.e., powered without water running through them).

Powerstream Pro features a compact design and can be mounted in any direction (with the exception of the RP12PT) - making it the ideal point-of-use water heater for virtually any sink installation.

The Powerstream Pro model RP12PT features thermostatic control. In warm climates where ground water is 60°F or higher, it can deliver a low-flow shower.

  • Unlimited hot water - Water is heated as it flows through the Powerstream Pro, so you will never run out of hot water.
  • Saves energy - Powerstream Pro is 99% efficient and heats water only when the tap is turned on. And, Powerstream stores no hot water, so there is no standby heat loss.
  • Saves water - Instant hot water means no more wasting water while waiting for water to get hot. Such cold water "run out" accounts for 80 billion gallons of wasted water per year in the U.S.

Frequently Asked Questions

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. "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.

Q. "What is CA AB 1953 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) and VT (S.152), and in the current Federal Safe Drinking Water Act requirements. In the new legislation for CA and VT only, starting in 2010, it will mean 0.25% or less (weighted average).

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 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. "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.

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. "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. "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.
