Needless to say our ancestors were not too worried about heating their log cabins. The large fireplaces had no problem reheating the one or two rooms where they lived. Of course, now that the boxes are family sized, people often feel that there is something different about how they are heated, and the good news is that the standard system Will also work in a newspaper house as a traditional structure.
Almost all log houses are built with at least one fireplace. At first we thought that our beautiful soap-top roof would heat the entire house, and we would use our forced-air propane heat as a backup. Alas, we have all been mistaken. Because we have a cathedral ceiling with a large loft, the heat of the stove goes directly to the floor, requiring two ceiling fans to recirculate the warm air. We were expecting this, but we also thought that the heat would spread parallel in the rest of the open space (dining room and kitchen). Not on your life! Even sitting on the sofa about 15 feet from the stove, I need a blanket. I am uncomfortably cold in the kitchen. I think if we had a regular ceiling, the heat could have been where we expected, but the ceiling volume of the cathedral ejected our calculations. In addition, the soapstone stove is designed to operate 24 hours a day, 7 days a week, and because we both work for life, the stove does not light up to the evening. This wood stove must be heated slowly at the risk of cracking of the stone, so, when it really cooks, we are ready to sleep.
Older fireplaces have traditionally sucked up all the warm air from the room, but modern designs are more efficient at recirculating heat. The most energy efficient fireplace is built in the center of the house, so that the heat from the pile is not lost to the outside. External batteries can create rear reflections if the fire is turned off, making the fire more difficult to light. If you plan multiple fireplaces, putting two of them (facing adjacent rooms) will give you the opportunity to build a chimney with two flues. Or you could put a fireplace over your oven, allowing two more smoke ducts in the same fireplace. A direct vent chimney will eliminate the chimney, but you will need to understand how to hide the vent on the outside wall. Or, if you are using a wood stove, you can squeeze the pipe through the wall and go up the outside, building a box around the pipe to simulate a fireplace. Depending on the look you want, you may want to leave the hose in the room and send it through the roof. This will give more heat.
It is a good idea to consider your heating and cooling needs early in the design phase. Although log homes are naturally energy efficient, it is not wise not to dispense with your system. You could possibly heat your entire home with a huge fireplace or wood stove, but the township will likely have minimum standards before issuing a building permit. In addition, you must consider the resale value. I know a person who tried to sell a $ 1 million handmade wooden house without a furnace, and, as you may suspect, the buyer never came. The house was classified as unfinished, and the installation of the heating system after the fact was too intimidating. A similar problem exists if you are trying to move away from the central air conditioner. Yes, log homes stay cooler in summer, but these August "dog days" can give you a perfectly unhappy night's sleep and a prospective buyer will probably not be as tolerant as the original homeowner. Indeed, our mortgage company would not consider granting a construction loan if we did not understand central air conditioning.
If you want to preserve the space of the ducts, you can use the forced air heat with the same ducts serving the air conditioner. Propane or oil are generally the fuel of choice in rural areas. If your interior wall space is limited, there are companies specializing in very small and high pressure piping systems that fit tight angles; These systems typically require a much higher initial installation cost. When you use traditional ducts, you want to keep the corners to a minimum, which helps in designing prominent walls that carry air directly to the second floor. An open floor plan offers a challenge, as it must be kept in mind that the rooms on the floor must be heated in any way, and you will need power and Return vents to create an efficient airflow. If you want to use complete interior walls, you will need to find another way to run the ducts, electricity and plumbing. We made this mistake, and there are not enough vents back in our room. The air is stuffy in summer even with the windows open.
Where do the aeration vents go? Since all our exterior walls are complete logs, many of our vents have been placed on the ground. If your inside walls are made of sheet metal or tongue, you can put the air vents where they normally go. One thing I would have liked to have done was to review the plan with the HVAC contractor because it put the aeration vents in places that I found More troublesome. Sometimes this can be helped, and sometimes it can not.
If you have energy and prefer to leave your thermostat to a minimum, you will find that the south side of the log house tends to be warmer than the Nordic exposure. Because the sun tends to descend closer to the afternoon horizon of winter, it is beneficial to organize your large windows facing south; During the summer, the sun will cross the roof, so it does not overheat your home. However, you may find that the north side of your house – which will not have direct sunlight – could be significantly cooler. The best solution is to install radiant floor heating (if you can afford it). Although this system requires a boiler instead of an oven, floor heating uniformly calibrates heat in your home, eliminating the blues from the north. With radiant floor heating, you must keep the thermostat stable all the time; The system is not designed to be denied when you go to work. In addition, you can use the boiler to heat your hot water as well, eliminating the need for a water heater. On the other hand, you will always have to install ducts for air conditioning.
Overall, the same considerations apply as in the regular construction. We thought we could go through a single heating and cooling zone, but in retrospect, two areas would have solved a lot of problems. In the long run, it is cheaper to do it properly in the first place. The redevelopment of a newspaper house will not be a breeze!
