This water heater is a fantastic way to get hot water by simply running or driving your van. It can heat the water through the van’s coolant lines or using the 750 (120 VAC) electric element off your inverter when you’re not driving. Check out our blog post about this water heater.

We sell the stand-alone water heater as well as the water heater with an installation kit that includes all the parts you need to connect this up to your Promaster van coolant lines along with detailed installation guide and exclusive installation video.

Description

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
