How to Buy the Ideal Window Exhaust Fan

!: How to Buy the Ideal Window Exhaust Fan

Window fans are easy to incorporate in any interior design as much as windows are a natural, energy-saving way to sustain proper ventilation. They are fans intended to be placed within the frame of a window, and a lot like their natural precursors, they have been designed to circulate cool air, as with a window cooling fan, as well as clean air, as with a window exhaust fan. For today's severe summer heat and temperature fluctuations, these fans provide a cost-friendly, energy-efficient solution.

While a heater keeps rooms insulated and an air conditioner cools them down, a window exhaust fan expels stale air to make sure the cool air you are breathing is actually fresh. Unless your home or office interiors require absolutely cold temperatures, an exhaust fan creates a cool breeze at a fraction of the cost of an air conditioner. Industrial fans generate greater centrifugal action for carrying cool air all throughout.

Consider a window fan that can be switched between intake and exhaust modes. Nice features your fan should have, because they are common enough, include two or three sleep-friendly quiet speeds, an automatic shut-off thermostat or timer, and easy to see lighted controls. Invest in an exaust fan with a 360 degree dual-axis rotation, if within budget, so it rotates horizontally and vertically.

The typical window exhaust fan has an electricity powered motor but a solar powered portable fan comes in handy for producing a cool breeze wherever you are. A window fan doubling as a table or floor fan would be another smart investment.

Portable Generator or Backup Battery System?

!: Portable Generator or Backup Battery System?

Do I need a battery backup system for my pellet stove or a backup portable generator?

The answer hinges on the length of the "average" power outage where you live. If you live in an area where power outages are infrequent and last less than 10 or 12 hours, a battery backup system for your pellet stove makes the most sense.

Battery Backup System

A 10 hour battery backup system comprised of excellent, yet reasonably price components costs around 0. This is half the cost of a generator system of comparable quality.

Although a portable generator has the capacity to generate power for many appliances, a backup battery system can also be sized to service more than one appliance.

Portable Generator

As I write this article, an ice storm is snapping power lines across the Midwest and hundreds of thousands of households are without electricity. It will take utility crews working round the clock a week or more to restore power.

When a power outage is measured in days rather than hours, you'll need a backup power source for more than just your pellet stove. These would be your survival appliances like the fridge/freezer, stove top burners, well pump, a few light bulbs and, most important of all, the large screen TV.

The most noticeable difference between a battery backup system and a portable generator is the noise. While a battery backup system provides a silent transition to "off grid" power, a portable generator will be a noisy reminder to your neighbors that you had the knowledge of foresight to plan ahead for the safety and comfort of your family.
