  • 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.

  • The Isotemp SPA Stainless Steel Marine Water Heaters are available in 5 sizes ranging from 15 to 40 liters capacity (15, 20, 25, 30 & 40 liters).

    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.

  • Using air which is blown through the condenser by a fan is the traditional way to remove the heat. It is important that the compressor compartment is well ventilated allowing cold air to enter from below and hot air to escape to the top.

  • Using air which is blown through the condenser by a fan is the traditional way to remove the heat. It is important that the compressor compartment is well ventilated allowing cold air to enter from below and hot air to escape to the top. The Isotherm Compact Classic is an air cooled compressor unit designed for simple installation in existing top or side-loaded refrigerator boxes. It uses a Danfoss Compressor to cool an evaporator fitted in your refrigerator box. Air-cooling is a traditional way of removing heat with a condenser where air is blown through by a fan. It is important that the compressor compartment is ventilated so that cool air enters from below and hot air is allowed to escape above. The lower in the boat the compressor is installed the more the surrounding air is chilled by the outside water. Two styles of evaporator are used, round and flat. The evaporator can be fitted in any position, and requires an installation opening of only 1-3/16" in the refrigerator wall. The temperature is adjusted by a thermostat which also has an ON-OFF switch. These units provide refrigerator capability with temperatures down to 36°F; except model 2017 has freezer capabilitiy (to 7°F) for a separated chamber. • All units come as complete pre-filled "do it yourself" kits • Amperage shown is with refrigerator filled to one half capacity • Cooling/venting fan included • Evaporator: O-shaped; model 2017 is flat and can be bent to fit • Compressor dimensions: 10.63"L x 6.31"W x 6.13"H (model 2017 is 12.44" long) • Weight: 20 lbs. (except model 2017 is 26 lbs.)
