Having warm water for showering and washing dishes while at anchor for an extended period can be a luxury for the cruising sailor. We at Custom Marine Products have come up with an easy and convenient solution; heating water using radiant energy from the sun.
Here's how it works:
Solar panels get quite warm on sunny days. The back of a solar panel tilted toward the sun may reach 140° F. Mounting a heat exchanger (collector) to the back of the solar panel enables the collection of radiant heat passing through the back of the solar panel. Circulating water from the water heater through the heat exchanger heats the water in the water heater. The water heater becomes a heat storage vessel. Water is circulated using a low draw circulation pump designed for this purpose so very little electrical energy is consumed.
You no longer need to run your engine at anchor to heat water.
Heat water to 115° F+ in an hour.
Kits are available for all CMP rigid panels and many other brands
Kits include: heat collector, insulation, panel backing, pump, tubing.
