The Whale Seaward 6-gallon galvanized heater in 240V is a compact unit for boats with 240-volt AC systems. Its 1500W element heats a 6-gallon tank, which suits smaller boats with one head and a galley. Front heat exchanger connections let engine heat warm the water while underway.
Whale designs these heaters specifically for harsh marine conditions. The galvanized steel cover gives dependable corrosion resistance for less money than stainless or epoxy, at the cost of a little more weight. Ignition-protected controls are built in.
Make sure your shore power and onboard wiring are 240V before ordering. A magnesium anode is available separately to help prevent corrosion inside the tank. Browse more Water Heaters for larger tanks.
