Understanding Doorway Fans And Which Ones To Invest In
Wood stoves are appealing because they work slowly and without electricity. But in general, it makes sense arranging items in the house properly so heat from the stove can flow to where it's needed most. If this can be achieved, the role of a doorway fan is eliminated completely.
For example, if you have a two story house with an inbuilt wood stove, the source of the heat would be located in the open plan main floor for efficient heat distribution. In this case, the bedroom and the upper floor will naturally stay cooler, which is just fine for most people. Again, the basement stays cooler, which is okay if that space is used for storage and other utility tasks. As long as the house is well sealed and insulated, heat from a single source can be evenly distributed.
However, the problem is, most homeowners don't have time and the luxury to design their homes around these requirements. Therefore, for this category of people, something must be done to boost heat circulation around the house.
If you choose to install your wood stove in the basement to keep wood chips, fuel and ashes out of vicinity, then it is highly likely that you'll have a hard time moving heat upwards. In fact, there is no one effective solution that can address this problem, which is why most architects don't recommend it at all.
You could install floor grilles to help move the much needed heat upstairs. However, the problem is that such grilles will have to be extremely large to allow sufficient air to pass through them. Furthermore, the hot air must have a dedicated path upstairs and a large path which carries replacement air back to the basement.
But regardless of what you do, never try blowing hot air from an enclosed basement upwards because the resulting difference could create a backdraft.
So if you have a spacious house, you should make sure that the hot air is circulating efficiently and conveniently. This calls for the use of doorway fans which blow this air across rooms for even distribution.
These are portable fans designed with a cord and plug. Because they are usually hung on the top of the door, their heights allow them to pull warm air so it can be transferred to rooms that needs it.
Most of them fit nicely on the top corner of the doorway. However, take note that some models may be noisy than others -- it is generally believed that newer models tend to operate quietly than older ones. Again, the price tag dictates what you get as a doorway fan.
Doorway fan examples worth purchasing
The EntreeAir fan is designed like a quarter piece pie to fit well on the corner of your door. The fan is readily available on Amazon with prices being low as ever. Prices generally start at $29 all the way to $50. Check this link http://is.gd/Y16csZ to find out. You should be able to select from the list of fans therein.
Another brand by the name Minuteman consumes 25 watts. EntreeAir, on the other hand, runs on 27 watts of energy. It's good to know the slight differences in power consumption. Keep in mind that the cost of running a fan for 24 hours a day, 30 days a month is $1 on average. But assuming that you can make your own fuel, the cost of running these fans can pay for themselves in one heating season.
Through-the wall fans
These are fans that have openings on both sides of the wall. The motor and blade are also incorporated into the unit to propel hot air efficiently.
These fan pieces automatically become a part of the house, so they are connected to an easy-to-reach switch for convenience. The fan should also be located high up the wall. And if possible, it should be situated away from the doorway.
The reason why you should place them high up the wall is that hot air needs to moved by the ceiling and into the next room. So it is good that the fan could send the hot air towards the floor of the room which is away from the heat source.
You can shop around to see what suits your heating needs. But regardless of the type of fan you buy, it should be efficient and affordable to run. Otherwise, it beats logic to use a doorway fan that is costly to run yet the same results can be achieved with another fan that is cheaper to run.
