    Isotemp Water Heaters General Features:

    • All Isotemp water heaters use two thermostats: a temperature thermostat and a safety thermostat designed to trip in the event the tank is run dry
    • All Isotemp water heaters come standard with a mixing valve
      • Every Isotemp tank features a safety mixing valve that regulates the temperature of the water coming out of the tank so that water heated to 160+ degrees will not scald boat owners or their guests
      • Temperature of the hot water coming out of the tank can be adjusted to the preference of the owner by turning the mixing valve on the water heater
      • This feature allows the thermostat to be set at a higher temperature, while keeping the user safe from scalding
      • It also extends the capacity of onboard hot water by using only a fraction of the water in the tank to produce the desired water temperature
    • Standard heating elements are 750 watts which won’t overload generators or trip dock breakers
    • All Isotemp products are CE certified and manufactured in ISO certified facilities
    • All Isotemp tanks are covered by a 5-year limited warranty against leakage due to manufacturing defect or corrosion and a 2-year warranty on all other parts
    • 750 Watt immersion heating element as standard on all Isotemp Water Heaters
      • 1200 Watt and 2000 Watt Elements are available as an option (Special Order Only)
        • Note: 2000 Watt heating element is only compatible on 230 Volt versions

    Isotemp Slim 25 Marine Water Heater Features:

    • Specifically designed for use on yachts and boats, and built with highest quality components to ensure long service life in the marine environment
    • Aluminum mounting brackets adjustable 360° for horizontal (deck) or bulkhead (vertical) installations
    • Engine water heat exchanger and immersion heating element positioned at bottom of tank to ensure consistent heating of all water in tank
    • Extra-long, corrugated coils for high heat exchanger efficiency
    • Water inlets and outlets specially designed to minimize mixing of cold and hot water
    • Thermostatic mixing valve conserves hot water, protects against accidental scalding and minimizes power consumption
    • Special 7.0 bar / 100 PSI safety valve makes winterization easy
    • Internal tank, engine water coil and fittings made of AISI 316 stainless steel
    • External jacket / tank and mounting feet made of non-magnetic AISI 304 stainless steel
    • Ultra-thick polyurethane insulation minimizes heat loss
