    SEISCO Tankless Electric Micro-Boiler
    The 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.

    Product Applications:
    Seisco SH Series tankless electric space heater is designed for use in residential and commercial hydronic space heating applications such as radiant floor heating, baseboard, hydro-heat pump and snow melting systems.

    This new micro-boiler is the ideal replacement for traditional boilers and tank-type heaters and is the enabling technology for use with active renewable energy systems such as solar and geothermal systems. The temperature activated control works effectively in low pressure and re-circulating systems.

    2 Chamber Models: SH05, SH07, SH09, SH11, SH14
    Perfect for driveway snow melting, room additions, small shops, small condos, garages, cabins, etc.
     
    4 Chamber Models: SH18, SH22, SH28
    With optional equipment, these models can be used as the single heat source in combination systems for potable hot water and space heating.

    Minimum AMP whole house electric service recommended:
    SH18 - A minimum of 125 AMP
    SH22 - A minimum of 150 AMP
    SH28 - A minimum of 200 AMP

    •     2 and 4 Chambers Models
    The same advanced microprocessor technology and thermoplastic construction are used in both 2 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 Detection
    Seisco 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 Control
    The 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 Logic
    The 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.

    • 5 Year Limited Manufacturer's Warranty

    SAFETY FEATURES:
    Seisco was designed with a complete array of dependable safety features to prevent harm to the user and the heater. 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.

    • A leak detector is mounted on the casing that in the event of a leak sounds an alarm to the user.

    • 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.
