Heating your boat without Electrical Power!

For small boats 20-25ft, the Newport Solid Fuel Heater is a small stainless steel solid fuel heater that uses no electrical power at all. This is good news for sailors who are very aware of power consumption on board and know that every amp counts.

Requires 3” diameter chimney parts.
Minimum 4ft of chimney is required, a 6ft straight run with no elbows work best.
Chimneys 6ft or longer we highly recommend a barometric damper.
Permanent fresh air vent needed in the area of the unit.
Decorative laser cut door.
Creates a dry heat to dry out the moisture inside the vessel.
Removable ash drawer for easy cleaning & damper control.

This bulkhead mounted solid fuel heater is a reliable yet beautiful source for heating your boat. The maximum output of this heater is meant for 8000 BTU’s with a minimum of 3000 Btu’s. This heater is designed for heating your boat,  a small area, or as an aesthetic feature of your boat. Combustion options include a 1” piece of wood, a handful of charcoal briquettes, peat or presto log. There is a short video from a customer of Dickinson showing Presto log burning –

Installing your Heater
Location – Plan your heater’s location prior to installing to ensure the location chosen will fit the specifications and safety clearances. Combustible material closer to the heater then the specified safety clearances must be lined with insulation or cement board and a metal liner with a 5” standoff for air movement behind. Another alternative is using insulation or cement board and ceramic tile. The back of the heater and the first length of chimney pipe should also be lined with such material.
Here is a simple diagram to show you.

Mounting – The heater has the appropriate brackets attached to secure the heater to the bulkhead. Locate the heater as close to the floor as possible for maximum stack length and to provide good heat convection for heating your boat. The location must also take into consideration stack configuration and ensure that the chimney above deck is clear of any obstruction.

With regards to ventilation. you MUST replace the air inside your boat at the same rate that the heater is removing it. The higher the heater’s burning rate, the more air the heater will require. If the airflow is blocked or restricted, the heater will burn inefficiently, creating soot, blow out and can be a health hazard. A permanently open fresh air inlet MUST be installed or dedicated to the heater. This inlet must be at least 3″ in diameter. Ducting fresh air to the heater is also an option. It is important to create and maintain positive pressure inside the boat. High winds can draw air out from the boat and thus create negative pressure. This condition can result in downdrafts. Ensure that when you do have windows open that they do not create a suction effect in the cabin due to the window’s position and the wind direction. In a similar way, it is possible for the air intake on your engine to suck the air out of a cabin if it is not properly vented.

The heater is a natural draft appliance and it creates its draft pressure like a chimney in a wood stove. The rising, heated air in the chimney pulls fresh air into the heater as it rises up the chimney and exits the flue cap. The greater the draft pressure, the more able the heater will be to resist strong winds, overcome flue elbows that inhibit draft and the hotter you will be able to get your heater without sooting. A CO alarm should be installed in the boat as a form of good practice.
