An oil furnace is the heart and soul of your homes heat regulation and air flow system. When the old furnace becomes old and tired, it is good to find a new unit that can match the outputs and save you money in the long run on efficiency.
Dealing with Conversion Issues
If you are converting from electric or gas to an oil furnace you will want to be sure you have the correct set-up for the new unit you are putting in your home. Double check electric voltages and the fuel line connections. Generally the electric connections will be the same, and your serious conversion issues come from the type of fuel lines you are presently running. These can be fairly inexpensive to purchase and can be installed quite easily, you are going to want to check the new units specifications in regard to the type of inputs you will want when installing it.
To hook up your new oil furnace on an existing oil furnace set-up you will simply want to connect the fuel line to the unit once you have it secured in place. During the initial positioning of the new furnace, take into account which direction the various hook-ups are facing and try and line them up to the old lines as closely as possible. This way when you go to connect the existing lines to your new furnace, you will not be scrambling to make an extra 2 to 3 feet of length on a connection to come together, which also prevents you from moving the unit again to make things fit. Most furnace oil line connections are of universal size, thread and diameter to make for easy servicing by Field technicians.
Electric lines coming into your oil furnace should be easy and minimal. With electric lines you can easily extend these without much work if they fall short of the target connection, and this should be your last concern when lining up your new furnace. Your electric connections should easily be wired in the same way you take them out of the old unit, be sure your voltages are correct to avoid burning out the electrical system in the furnace or your home.
Intake and Outtake Ports
Your oil furnace functions by taking in the cool air from ground level in your home and then passing it through the heater in the unit itself, where it heats the air and pushes this out the hot returns throughout your home. You will want to make sure that your cold return intakes and the hot air returns line up with a tight seal to prevent pressure loss.
Air Pressure Checks
You can make your oil furnace more efficient as well by having your home pressure tested. This is where your home is sealed shut and they run an air pressure device to check for structural leaks. These leaks can make your furnace work harder and even cause yur home to loose cool air in the summer and warm air in the winter into the outdoors.
