Isotemp Waterheater BASIC 75 Stainless Steel 20 gallon, 750W/115V with safety mixing valve, USA Plug

Isotemp Stainless Steel Marine Water Heaters are specifically designed for use in the demanding marine environment. Isotemp features a brushed stainless steel cover and a 316-grade stainless steel inner tank that is backed by a 5-year limited warranty against leakage due to corrosion or manufacturing defect.

Isotemp Stainless Steel Water Heaters achieve the highest capacity by optimizing the position of the engine water heat exchanger as well as the electrical immersion heater. These 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.

All Isotemp tanks come standard with the innovative Isotemp Temperature Control Safety Mixing Valve which protects users from scalding hot water. Water heated with engine heat exchangers can be heated to 190 degrees or more which can scald those unfamiliar with boat water heaters. Water will also be heated to 160+ degrees with just the electric heating element alone. By adjusting the valve, the Isotemp thermostat-controlled mixing valve mixes the boat’s water with the hot water to deliver the temperature you want at the faucet. This mixing action also speeds recovery time and extends the volume of hot water you get from a smaller tank.

The Basic 40 and Basic 75 are the only two models that have the double engine heat exchanger option. The double coil is sometimes used by boaters who have hydronic heating to maximize use of the heating. They are often used in conjunction with two engines such as a main engine and a generator to take advantage of the surplus heat provided by two separate sources.

• Extra long, corrugated coils for high heat exchange efficiency
• Special 7.0 bar / 100 psi safety valve

• Ultra-thick insulation for lowest temperature loss
• Electrical plug and play immersion heating element, especially designed to heat also the water at the bottom of the tank
• Thermostat mixing valve protects against scalding and delivers consistent temperatures at the faucet
• Standard 750 watt immersion heating element heats water quickly but will not overload generators or dock breakers
• Optional 1200 w/115/230 volt or 2000 w/230 volt elements for larger tanks
• Robust design
• Water tank in 316 grade stainless steel
• External cylinder in stainless steel
