A wealth of important information below, so please read.
The DAW1215-SS 120 Volt heater was previously also marketed as the CH1215-SS with the CH standing for Cabin Heater. In the CH version the optional thermostat and an attached power cord was included.

This is the heater we have used while living aboard full time in the northeast.

Although the CH is no longer available, the DAW heater itself is the same, but the thermostat is now an option that you add during installation along with a locally sourced power connection/cord and cord grommet.
(We suggest the PT-1 thermostat for 120 Volt models and the PT-2 for 208/240 Volt models.)
With no maintenance other than vacuuming out the dust seasonally we finally had our first fan failure after 15 years and that was the unit in the head that is exposed to more moisture and dust than any of the others.
We usually keep the thermostats at the highest setting and simply adjust the wattage as the outside temperature changes. This keeps the fans running 24/7 so there is no stale air and moisture build up.
Our 6 heaters, spread throughout the boat, are always running in winter, but never at full power, just enough power to stay comfortable. Turn up the wattage on cold days and at night, then turn down during the day.
The thermostat however is great when away from the boat for freeze protection or to limit power use when not needed.
Keep in mind, these are cabin heaters and ARE NOT ignition protected
bilge or engine room heaters for use where explosive vapors may collect.
Watch the total number if watts you draw, so you don't overload or blow circuits. Our boat is usually built with two 30 amp circuits, 1 for domestic use (outlets, water heater, microwave, etc.) and 1 for air conditioning.
The air conditioning circuit is used for half the heat in the winter and we added one more 30 amp circuit for the remainder of the heat. With this arrangement, the load is divided and we don't have to worry about a circuit tripping on a cold night. If you are unsure, ask your local marine electrician.

and 3 wattage/power levels
(Choose the model that's right for your boat)
300 Watt (Usually in stock)
Perfect for mild temperatures and single motors with nothing else in the compartment.

600 Watt (Special Order, allow extra time)
Used for mid-range temperatures on a single engine or dual-engine in milder climates.

600 Watt MiniMax (Special Order, allow extra time)
Same as above, but smaller and more versatile. Mount in any position (6"x4"x3 1/8")

1000 Watt (Special Order, allow extra time)
Ideal for very cold climates, such as the North East or Great Lakes or a dual motor engine compartment. If there’s additional equipment in the compartment, including tanks or generators, we suggest two 1000W units.
We use 300 watt heaters in our boat here in the North East, but as liveaboards the entire boat is heated and these just provide a little extra for the engine compartments that already get some heat from the cabin heaters.
