SEISCO Tankless Electric Water HeaterThe tankless water heater that others can only claim to be!After 14 years of research and testing, the SEISCO, whose technology has earned its developer 5 separate U.S. and many additional foreign patents, is recognized as the STANDARD for all tankless water heaters.The SEISCO tankless water heater has earned International recognition for providing the highest level of temperature control performance, reliability and safety in its operation over any tankless water heater anywhere in the world today. Application:Two-chamber models designed for point-of-use applications.This on-demand tankless water heater is the enabling technology for use as back-up to active renewable energy systems such as solar and geothermal water heating systems. The temperature activated control works effectively in re-circulating systems and in combination with tank-type heaters. Seisco RA-09The RA-9 is great for point-of-use applications such as coffee bars, single sinks and emergency showers in office & industrial warehouses; to comply to code. A perfect replacement for 10 & 20 gallon tank heaters in RV’s and small motor homes. Supplements existing water heaters and requires only one 40 Amp, 240 Volt electrical circuit.Seisco RA-11The RA-11 is great for point-of-use applications such as coffee bars, office & industrial warehouse wash sinks, single lavatory and emergency showers; to comply with code. Perfect for RV’s, small motor homes, Radiant Floor heating, and supplements existing water heaters. Requires only one 50 Amp, 240 Volt electrical circuit.Seisco RA-14The RA-14 is excellent for point-of-use applications at single showers and multiple sinks. Ideal for supplementing existing water heaters which are unable to satisfy user requirements in beach houses, hair salons, horse stables, hunting and fishing cabins. Great for small homes, condominiums and individual entities, where the incoming water temperature rarely falls below 75 degrees F. Radiant Floor heating systems, spas and hot tubs. Requires 60 Amp, 240 Volt electrical circuit.Product Benefits:• Continuous and Endless Supply of Hot Water • Space Savings • Safety and Health Benefits • Smart Technology • No Maintenance • Environmental BenefitsProduct Features:• UL 499 Approval Listing for Water Heating Applications• Works with tubing and manifold systems• No minimum flow activation required• Built-in DSM Utility Integration option• Compatible with Home Energy Management Systems• No moving parts• Very small & compact• Light weight modular construction• No restriction to flow• Standard 3/4 inch plumbing connections• Microprocessor digital control• Power sharing & variable power control technology• Continuous venting• Heats continuously only when needed, no storage• Self-diagnostics• Redundant safety devices• High performance polymer nylon chamber material• Rust & corrosion resistant• 2 Chambers The same advanced microprocessor technology and thermoplastic construction are used in both 2 Chamber and 4 Chamber models, therefore, many of the parts are interchangeable. There are no moving parts or flow restricting devices used in Seisco heaters. • Flow/No Flow DetectionSeisco uses a unique flow/no flow detection system utilizing temperature sensors for flow detection. In standby, the heater maintains a very subtle temperature gradient and flow is detected when there is a change in the gradient. • Microprocessor ControlThe advanced microprocessor control turns the power on through a set of relays and turns the power off when flow stops. The most important feature may be the patented "Power Sharing" technology which provides for evenly distributed power to the heating elements. This in turn, helps eliminate scalding potential, scaling and sediment build-up. • Control LogicThe control logic allows the power level to vary which is beneficial in minimizing the use of power for periods of less demanding usage. • Quality Construction: Seisco heating chambers are modular and molded of light weight thermoplastic materials. The chamber is specifically engineered for durability in harsh water heating environments and capable of withstanding extreme temperature swings and pressure changes. Heating elements, sensors and detection devices that come in contact with the water, are machined in brass or made of copper to help resist corrosion. Standard 1 inch, flanged screw-type heating elements are utilized which are interchangeable with heating elements available at local hardware stores. • 10 Year Limited Manufacturer's WarrantyNOTE: RA models are designed for residential applications. If used in a commercial application, the factory warranty is voided; if used with 208 volt [AC] operation, the available voltage and therefore the temperature rise are derated by 25%. Commercial units are available with full factory warranty in 240V and 208V.

There are several redundant safety features as well. • Dual high temperature switches on independent circuitry in addition to the control's internal high temperature shut down. • Dual low level detectors are used to prevent dry firing of the heating elements.• Electrical Surge Protection - Although the control board is protected against electrical surges, additional heater protection is achieved when the relays are opened during periods of standby, providing no path for the surge to reach the heating elements. • Venting System - The chamber is designed with a patented venting system that continuously vents harmful gasses and air during operation. • The microprocessor control is programmed to provide self diagnostics that significantly reduces troubleshooting and service time. In the event of a problem with the heater, the control emits a visual or optional built-in audible code. There is no maintenance required of the Seisco. However, there are clean-out plates below the heater chamber to allow removal of sand and grit that may build-up from a well water system.
Flow Rates:The flow rate for each model is given in the "Temperature Rise" section of the Product Specification Table above. Along with the temperature rise, the flow rate must also be determined in order to choose the appropriate Seisco heater. The flow rate is determined by the type of faucet and also, life style. Refer to the chart below for typical faucet flow rates in the home. However, if the desired life style in the home requires running multiple faucets at the same time, then the flow rates must be added together to determine the peak flow demand. The Seisco or the possibility of multiple Seiscos should be selected to match the peak flow rate.
Below are typical flow rates for new residential construction. There may be exceptions with new designer type fixtures and faucets. For instance, large custom body spa showers whirl pool and Jacuzzi tubs may have faucets with flow rates ranging from 7 gpm to 14 gpm. However, a combination of multiple Seisco heaters [preferably plumbed in a parallel configuration] can be installed to match these higher flow rates. The same peak design approach would be necessary for the anticipated life style of multiple flow rates occurring at the same time. Otherwise, use the table below and match the Seisco according to the peak flow and associated temperature rise of a single tub or shower.
