Then make a firewood and check the thermocouple and the valve behaviour (by simulating the air admission with your stove manual controller) To put the Arduino regulator in automatic mode, you have to put the potentiometer to 100%. The disadvantage of the electronical method is that the method needs power, and that it is considerably more expensive. Reply It is sometimes assumed that taking air from outside through a duct saves energy because the stove doesnt use up indoor air and cause outdoor air to be drawn in through leaks to replace it. In the 1980s, when large exhaust systems like downdraft kitchen range exhausts began to cause spillage from fireplaces and stoves in reasonably tight houses, a consensus quickly formed around the idea of bringing combustion air from outdoors, just as had been done in mobile homes for decades. .

Our next project will be installing the domestic hot water coils in the spring. Supplying outside air keeps your warm air in the room instead of sending it up the chimney to be replaced by cold drafts entering your space through cracks around windows and doors. Fire needs oxygen to continue. This means less work, less wood use and an improved combustion. The first is to replace the air sucked out of the house by the wood burner, based on the idea that houses are airtight and the wood burner will use up all the oxygen. You can get some nice PID curves by getting the values with Arduino serial port and plotting them. Where necessary the indoor air pressure should be controlled to minimize depressurization. With the regular old fireplaces and pot belly stoves we know and love, that replacement air is going to be many, many cubic feet per minute and is going to be in the form of cold air seeping in through cracks, under doors, around windows any way it can get in. very smart. struggling to stay alight, open up the main vent as much as possible to get the Paul( London). But it doesnt matter which theory you pick; none of the three stands up to scientific scrutiny. The extent of building depressurization is deducted from potential chimney draft, like this: theoretical draft depressurization = net draft. So the air consumption of a wood stove is a tiny part of a much larger exchange of air between the house and outdoors. Exactly what i'm looking for. It was very easy to install. The boiler requires very little maintenance and is simple to operate. Certain wood stoves might not have to have a fresh air intake specifically connected to outside the house, since it can get enough air from inside the house.
