Marine/Boat Hot Water Heaters

Compare our Marine Hot Water Heater Kits to find the best kit for your boat. Instead of having to run your engine, these easy to install and affordable kits can provide enough hot water to comfortably shower and wash dishes
First, select the type of kit that best fits your needs (make sure to read information about freezing temperatures below.) 
Then use the table below to decide how many panels you will need for your hot water tank. 
 If it regularly freezes in your area, we recommend purchasing a "Freeze Protected" Kit. These kits operate year-round, without needing to be drained when the temperature drops below 38  degrees Fahrenheit. Our Marine Direct Circulation kit must be drained during freezing temperatures. Damage from freezing may cause the panels to leak, and voids our 10 year leak warranty

Find your location on the map below. Use the table to approximate the amount of panels you will need for optimal efficiency. 
If your panels are more than 25 ft from your water heater(50 ft total run), we recommend adding an extra panel. Extra panels can always be added after your installation is complete.
