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
