Motor-Aided Spark Ignition
Combination Gas, Electric Water Heaters: use your engine’s cooling system to warm your water as you drive!
Utilize your motorhome’s engine coolant to aid water heating with a “heat exchanger” to circulate the engine radiator coolant through an embedded tube on the external wall of the porcelain lined steel tank as you drive. This method warms your water using engine heat in an environmentally efficient way. The motor aid option also increases the capacity of the engine cooling system in many instances.
