If you are a boating enthusiast and will be using your boat during the winter months, you will want to install a cabin heater to keep you warm. The heater that will best suit your needs depends on the size of your boat and how much money you are willing to spend for that comfortable warmth. Installing a cabin heater will take a little time, but as long as are patient and skillful, you will appreciate your new construction.

Where to Install Your Heater

Location of your heater is of vital importance. Your heater must be placed in a position that will give you maximum performance while also being located where your ducting routes run. Your boat's battery and fuel tank are primary sources of operation for your heater. You will also need to ensure that the heater is not too far away from those sources. Try to avoid having to use sharp angles in your ducting. If your ducts are constructed with less angling, you will get the maximum heat penetration from your heater. Angles that are too sharp often reduce the heater's performance.

Installing the Heater

After you have determined where your heater will be, it is best  to run your ducting in a location that will prevent the ducting from being damaged if the waters you are navigating become turbulent. Once your heater is secured in the location you determine is best, you will have to install the vents.  Some boats will have pre-cut holes. If these holes are convenient to the location of your heater it is acceptable to use them. Drill holes carefully so that you won't damage the the outside appearance. Before you begin ducting, ensure that you push the thermostat and control wiring through the newly drilled holes. The ducting will have to be covered with plastic bags to so that you won't cause damage to the thermoduct insulation. Place insulation over the ducting for additional protection.

Getting Fuel to Your Heater

Your heater uses a solenoid pump. This means the pump draws fuel from your boat's fuel tank and forces it into the heater. This is an important step and must be performed carefully for your safety. You will need to get a lift pipe that fits to your fuel tank. After fitting the pipe, gently curve your copper pipe to your tank and attach it securely. Now that the lift pipe and fuel pipe are connected, run a second pipe from the tank to your heater.

Your heater comes with an exhaust system. A swan neck exhaust is best as it will not allow water to get into the exhaust and potentially damage your heating system. To attach your exhaust system, you must drill a hole into the transom and check for accuracy by taking the exhaust outside your boat and seeing that the two holes line up. After verifying, add a marine sealant to get a secure fit, and attach the skin fitting for the exhaust.
