Not only is an efficient heater a wonderful luxury, it greatly extends the sailing season.

It was about 40° F when I got to the boat the other day. Had a few small projects to accomplish and I needed to complete some reading for a college seminar I teach one night per week.  When we rebuilt the Far Reach we installed a small Danish designed gravity drip heater called a Refleks M66MK.  It is normally set up for diesel fuel but since we don’t have an inboard engine we jetted  it for slightly more efficient kerosene.  The combusted fuel is vented out of the boat via the flue and a Refleks smoke-head.

The fan on the heater top is called an Eco Fan. It runs through a process called the pelitier effect which is the result of the second law of thermodynamics—heat flows from an object at a higher tempature to a body at a cooler temperature.  The fan sits on the cast iron heater top-plate.  The fan base absorbs heat which in turn moves towards the cooling fans.  In the process, the heat passes over a thermocouple.  As as a result, a small amount of electricity powers a 12 volt fan located in the fan body, which drives the fan blade.  The fan does a wounderful job of moving the warm air around the boat.  It can also be repositioned to blow the heat in any direction desired.

When I arrived at the boat it was 42° F.

In no time the boat was toasty warm. The Refleks Heater Has settings from 1-8.  We had it on level 1 or 2 … so it’s very efficient.

It took maybe 40 minutes to get the temp up to 72° F.

The boat is wonderfully comfortable and quiet.  Like a well made tiny house but ready to go to sea and serve as our magic carpet to any place we may desire.
