Isotemp 601521 Slim 15 Electric Marine Water Heater - 4 gal.

The Isotemp 601521 Slim Water Heater comes from the distinguished line of Isotemp products, internationally acclaimed for their excellence in the marine industry. Specifically tailored for marine and campervan use, the Isotemp water heaters are used in over 160 major boat brands, including center console, pontoon boats, cruisers, sailing boats, and mega yachts. The Isotemp water heaters are not only characterized by their elegant design but also their rugged construction, ensuring that you have a safe and abundant supply of hot water on board.

Engineered with the challenging marine environment in mind, the Isotemp 601521 features a 316-grade stainless steel inner tank that is acid-resistant, guaranteeing longevity and performance. Unlike conventional aluminum-core water heaters, this unit comes with a brushed stainless steel external cover that adds a layer of durability and aesthetic elegance. The water heater also incorporates state-of-the-art components like an extra-long, corrugated coil for high heat exchanger efficiency and a special 7.0 bar/100 psi safety valve for easy winterization. Backed by a five-year limited warranty, this product promises years of trouble-free service.

The Isotemp 601521 is designed for efficient power consumption, featuring an immersion heater of 115V / 750W. The unit is optimized for even heating, with the engine water heat exchanger and the electrical immersion heater positioned at the tank's lowest part. This ensures that all the water in the tank is uniformly heated. It comes with stainless steel mounting brackets and a 360° adjustable mounting feature, allowing for horizontal or vertical installations.

The Isotemp 601521 comes with a thermostat-controlled mixing valve that regulates the water temperature, mixing hot water with the boat’s water to deliver your desired temperature. This not only extends the volume of hot water but also protects against accidental scalding, a crucial feature given that water heated with engine heat exchangers can reach temperatures of 190 degrees or more. The water heater is also insulated with ultra-thick polyurethane to minimize temperature loss, making it an excellent choice for those who prioritize both safety and comfort.
