Internal vs external blower for Wolf pro hood
Comments (9)While we wait for Terrace1919 to respond, I can relate that I have a Wolf Pro Island Hood with their (Broan/Nutone) 1500 CFM (rated) blower on the roof. Duct length from hood to blower is in the 15 - 20 foot range (never measured it). A section of the 10-inch duct incorporates a Fantech silencer. At full power (with MUA path, baffle and other parts pressure losses) flow rate is likely to be around 900 CFM actual through the 10 sq. ft. of hood aperture. One can talk normally around and across the space under the hood. There is noise, mostly baffle hiss due to turbulence, but it is not annoyingly loud for cooking. My blower has some rumble that a re-balancing could help, I suspect. Some of my ducting wears automotive damping material to suppress any conduction of blower noise along the steel duct. This hood fully captures the cooking plume from my 3500W induction wok located under the far end of the hood. Hood height above the counter is about 35 inches. Blower control is via a conventional (at the time) triac/diac circuit above the middle baffle area on the controls side. If you replace the internal blower with an external blower, it would be safest, without evaluating the potential power capability of the existing motor control circuit, to use the same power rating external blower. Otherwise, uprating the embedded blower controller is another possibility, if Wolf is willing or you are an electronics experimentalist. kas...See MoreFL on the right -Duet 97hex vs. LG WM3875 HVCA vs. Miele 4842
Comments (26)@ livebetter If your laundry area is so specifically designed to accommodate a dryer vent for a specific brand/model, then you have bigger problems if that machine breaks down. You will never be able to replace it with anything but the same brand/model since your design is so specific to that model. I'm talking about the positioning of your rear ducting to allow both machines to be pushed all the way back so as to be flush with your counter. Most likely any other machine, even if vented to the rear with the proper door swing, will not fit due to the specific ducting location of the previous machine. I live in Arizona where most homes are tract homes. Out here, swapping locations is simply not a concern because the vast majority of laundry rooms don't have custom cabinetry or counters built above or around their machines. My last set was an Asko and I was tempted to install a counter above them in the laundry room. If I had done this, well the design would have to be ripped out and re-worked for the larger Miele machines. Whatever you design for your machines, remember that you won't always have those particular models. Keep some flexibility in the design....See MoreCanopy Bed vs. Ceiling Fan
Comments (11)That's a really tropical style of bed...the kind that is usually seen in rooms with ceiling fans. If it were me, I would definitely move the fan so it is centered over the bed. (and I would not give it a thought towards future resale, let them, the new owners, move it if they want to) I've had mine over a bed before, but my DH wouldn't stand for it being in the center.. he thought the breeze would be too much...all depends what you feel comfortable with, temperature wise. But I made sure that it was still centered between the width of the bed... I just moved it down towards the bottom..not at the bottom. Of course, I didn't have those rails to worry about. That bed is beautiful and I could see it with a ceiling fan slowly circulating above making the curtains (on the canopy) flutter ever so slightly. I wouldn't put one of those super modern style fans with that bed...and I wouldn't try and hide a fan, either. Just make sure the size is proportionate to the rails. I don't think you need to be hesitant about moving the fan to be in the center of the bed....after all, people do that all the time with a ceiling light over a dining table...it doesn't look right when it is off center. People center the light with the table not the center of the room. I don't know what the decor of your room will be... but again, that bed would be very comfortable in a Tropical British Colonial room. I mean, it's Tommy Bahama. Elegant and understated tropical.

Comments (18)Obi - I'm using three Vornado fans, which provide a lot of airflow. Two designed for small room air circulation and blowing directly on my plants. One is permanently on, the other only for a day after watering. The third fan is quite large and circulates air up my stairwell and into the loft, reducing temperature greatly. It's set on a timer to start an hour after my lights go on and maybe two hours after they go off. The power setting is the lowest for each to save on electricity. I recommend buying a power meter ($40) or borrowing one free from your local library to decide on the optimal power vs airflow setting for your fans. Like Daniel, I have had no issues with more blueish (daylight balanced) lights. I do not believe red lights are required for succulents to flower. At least, I confirm this does not apply to my: Haworthia, Aloes, Echeveria, Huernia, Lithops, Faucaria, Crassula, Schlumbergera, Euphorbia, Aloinopsis, Gibbaeum, and Lapidaria. My experiment/research is ongoing and hope to add more to this list. =)...See Moreopaone
