Overview

The Precision Temp ShowerMate propane marine water heater with patented VariFlame controls delivers an endless flow of hot water for the ultimate shower. It is perfect for boaters who don't want to leave the comforts of home behind while on the high seas.

The heater operates only when the hot water outlet is turned on. The VariFlame control system keeps the water temperature constant regardless of the flow rate or incoming water temperature. With 55,000 BTUs of heating capacity, the ShowerMate has five to six times the power of typical tank heaters - and all without engine power or shore power. It’s lightweight, compact, efficient and installs almost anywhere. In fact, the typical boat owner can expect to use very little propane for all this comfort; estimated 920 gallons of shower temperature water per 20 pounds of propane.

The ShowerMate propane fired tankless water heater is stainless steel construction and can be mounted as a closed combustion system for safety and peace of mind.
