Save Thousands with a New House Fan

Part of the buy tramadol fed ex EcoGeek home-improvement guide from A. Siegel.

Bit by bit, I'm EcoGeeking out my 1950s home. First the SEER16+ HVAC, then the light tubes into my laundry room, and now, the AirScape Whole House Fan (WHF).

Since I bought my home a decade ago, I'd been plagued by my old-style whole house fan (WHF). However old it might have been, this vertical fan sort of moved air (well, if I closed all but one or two windows), was an eyesore coming down stairs (a large dusty grid facing me), and was quite annoying when it came to changing weather (climbing into the attic to move the cumbersome homemade insulation into place). The fan was there and buy cialis pills often used (we really wanted to cut our energy use) but certainly wasn't the favorite part of just try! 50 mg viagra the house.

Well, along comes the energy audit and, even with that insulating system in place, the house fan ranked up there in terms of leaks out of the house. Another strike against this aging fan. Up to four strikes? Okay, time to finally get it out.

While we now have that SEER16+ air conditioning system, the preference is to viagra canada prescription turn it on as little as possible. Thus, with opportunity in front of me, the search was on for a new WHF that would meet my efforts to foster an Energy Smart house. After a long search, I became convinced that the canada pharmacy AirScape was the http://davenportinstitute.com/100mg-viagra best option and ordered one. Well, I didn't have a chance to see one before ordering and didn't  have a friend with one, so this was done with some trepidation. The results, almost three months in, suggest that concerns were unfounded.

Installation was extremely straightforward, one of the easiest DIY projects that I've encountered, probably manageable even without the instructions. The look is a major improvement. No longer is there a dusty large grill in my face every time I descend the stairs. Instead, there is a (smaller) grill overhead.

Noise levels have definitely fallen. The AirScape has four high-efficiency fans, rather than that old fan.

Cooling power is great. I can have low power to cool through the night or power up stronger when starting up.

But what is 5 mg cialis my real EcoGeek favorite element of the AirScape? What do I make sure to show visitors to the house? Actually, to make them listen to?

The whine at fan start-up and stop.

What, the whine? Why is that matter?

The AirScape comes with automatic insulating doors, with actuator-driven system for both opening and closing. Thus, the whine. No longer do I need to climb in and out of the attic just for fan insulation issues. (YEAH!!!) And the seal is tight enough to we recommend viagra overnight delivery eliminate that air leak issue.

The only problem: I live in the DC area (read: HUMID!!). A WHF is a wonderful thing for helping a home feel more comfortable but does nothing about that humidity. Even so, since having the how to get cialis in canada AirScape, the household air conditioning hours have fallen easily by 75%. That is an energy savings that I'm glad to be taking to the bank.

artificial breeze?
written by James, October 31, 2007
I know you said that you saw a marked decrease in AC usage, but how does the draw in feel? My parents, both from upper midwest so raised w/o AC, are both big proponents of the attic fan. Their new house is a ranch as opposed to a two story... long story short, the attic fan works only for one end of http://www.boehler.org/cheap-cialis-soft the new house and doesn't draw in that well (the artificial breeze is part of the perceived cooling) even when windows and tramadol overnight saturday doors are selectively opened. So, is this modern version a marked improvement in the artificial breeze?

Why active air?
written by P, October 31, 2007
Hi,

just wondering... it seems like wherever one goes in the US the ventilation systems are based on www.breinweb.nl active movement of air. In Europe, water based radiators and passive air ventilation is much more common.

In my experience, air based heating needs to be active all the time to work - when it's turned off it gets cold really fast - whereas water based radiators conserve the heat in the system and also create a much more even temperature...

Why go for air based in areas where the summers aren't really so hot that you need active cooling?

Am I missing something here?

If your house gets cold really fast when the furnace turns off, you need more insulation :) Sure, the radiators and the water in them add thermal mass, but if you had lots of thermal mass they'd probably be a pretty small contributor. And you'll be paying for ducts for cooling anyway.

On another note, I'm not sure how general my limited observations are, but in the US where I live it is http://www.filmusa.org/viagra-australia-no-prescription very common for multi-tennant buildings to have windows on only one side of a unit, even in the case of, for example, the one I live in, where every unit is a corner unit and could have windows on two sides for better passive ventilation. You need to set up fans. Three out of three places I stayed while on vacation in Germany had full natural cross-ventilation, windows on opposite sides.

Great tip

This is a a great tip most people wouldn't immediately think of - I've posted a link at GreenDeals Daily (http://GreenDealsDaily.com).

To seek to non generic levitra answer some questions ...
written by A Siegel ., October 31, 2007
1. Draw is adequate. Really, WHFs (this and others) will speak to power of fan unit and house. Almost certainly, my previous one was undersized. For as humid a region as DC is, the AirScape1700 is probably under powered but works to make the lowest priced viagra house more comfortable.

2. Part of path is 'strategy'. Fan on at night, pulling in cooler air/cooling house. Shades over windows to reduce sun. Perhaps, if someone is home, air conditioning might become required mid/late afternoon (to cut humidity and slightly reduce temperature). Since having the fan, very few occasions of 24 hour air conditioning.

3. To be clear, we are talking about WHFs rather than attic fans.

4. Good points re US vs Europe, and support point about insulation / air leaks. If there is bad insulation and significant air leakage, you're wasting power no matter the heating path. (And, well, I prefer -- for comfort and http://www.investordaily.com.au/discount-generic-cialis-online energy efficiency reasons -- radiant systems over forced air, but that is another issue.)

4. Interesting point about 'natural ventilation'. When conditions are windy/windier, the house fan generally is generic cialis mastercard not required. But, my home at least, there is not always enough natural air flow to rely on nature. (But, to be clear, the fan is not on 24/7/365.)

Cool roof too
written by Vin, October 31, 2007
Good points and review.

Also cools the roof for longer life and much less (or no) heat radiating from above, a big plus.

Use at night is common when it is cooler, best to pull air from low on the house where it is coolest. We live in MI w/o AC and do fine.

Thanks for the info we may change out our old fan also. Looks like a nice design depending on levitra online cheap cost.

Although we are able to pull a glued stack of order levitra TuffR foam board over the hole on ours from thru the fan by hand at the start of the winter with foam seals around the edge.

Vin ... thanks for contribution ...

You're right to do the foam board. I do a reasonable amount of DIY. That was scratched off the "honey do" list by getting the new fan. In any event, part of my issue was that I live in the DC area and there can be periods where the fan is relevant for two days, then I need cooling (or heating) for several days, and then there the fan is relevant, then not relevant for a month, then releveant for a week. It is a big plus that this remains ready to brand viagra for sale be activited 24/7/365 without my having to do anything. Thus, if in December, there is an afternoon (thank you Global Warming) at 75 degrees with the night predicted for 40, I could use the fan in the afternoon to warm the canada viagra mail house, freshen the air, and reduce my nighttime heating load.
