Isotemp Stainless Steel Water Heaters are specifically designed for use in the demanding marine environment. They have recently become popular in conversion vans, slide-in truck campers, and small trailers. This popularity has come from their high quality components built in Italy, and their compact design. Isotemp water heaters are very rugged and are designed to last for years of trouble-free service. Thanks to the Isotemp reputation for dependability, long life and handsome design, Isotemp water heaters add value to every installation.
Construction
Unlike common aluminum-core water heaters, the Isotemp marine water heater features brushed stainless steel cover as well as 316-grade acid resistant stainless steel inner tank that is backed by a 5-year limited warranty. Isotemp achieves the highest capacity by optimized positioning of the engine water heat exchanger as well as the electrical immersion heater. They are positioned in the lowest part of the tank where the water is coldest in order to ensure an equal heating of all the water in the tank. The water inlets and outlets are specially designed to minimize the mixture of cold and hot water.
Temperature
Water is heated to 160+ degrees with just the electric heating element alone. With the engine heat exchanger, water can be heated to 190+ degrees. The innovative thermostat-controlled mixing valve mixes ships water with the hot water to deliver the temperature you want at the faucet. This mixing action speeds recovery time and extends the volume of hot water you get from a smaller tank.

Fitment and installation
The Slim Square earns its name: 16 x 7 x 22 in and 35 lb, so it tucks into the narrow bays and under-bench spaces where a round tank will not go. The tank is 316-grade acid-resistant stainless inside a brushed stainless cover, backed by a 5-year limited warranty. Heating is a 115V / 750W immersion element that takes the full 4.2 gallons to 160+°F on electric alone; the built-in engine heat exchanger can push it to 190+°F if you tie into an engine coolant loop. In our own van builds we run the electric element only — no engine tie-in — and it is all the hot water a van needs. A thermostat-controlled mixing valve blends the output to the temperature you set at the faucet, which also stretches the usable hot water from the small tank. Max pressure 7.0 bar.
