Will this product work in the winter with below 0 temperatures? If not what would you recommend for year round attic ventilation from a gable end vent

It is controlled by a thermostat and really doesn't need to run unless heat builds up. If your roof can get to 85 degrees when it is 0 outside then yes it will kick on.

BT, this solar fan, because it has a thermostat that opens @ 85F would only circulate hot, humid air. If you are looking to circulate air @ lower temps., you would most likely need a fan that was ac elect. and controlled manually with a switch. I suppose you could remove the thermostat and the fan would operate whenever there was enough sun for it to run.

The question is not what the temperature is outside but what the temperture is present in the attic that you want to remove. The thermostat that comes with the Rand Solar powered attic fan is rated at 85 degrees. If you want to remove the air at a lower set point you will have to get an adjusteable thermostat.

Sure - as long as you have sunlight it will come on. You can use it with OR without the thermometer. If you use it with the thermometer, it will only come on at 85 degrees or higher AND with sunshine. If you don't, it will come on whenever you have sun on it.

I just went outside to check and it is running like a charm at 18 degrees. Another good result of continuous winter use is what appears to be a lower incidence of icicles/ice dams even with the 12 inch roof soffit on my house and up to 2 feet of snow on the roof.

The component that shuts off power below temp is inline on one cable, you can unplug it and get continuous power, but i dont know if the motor was designed to run continuously.

I have the unit installed in my attic in New York. Doesn't get quite as hot here but any attic is pretty hot during the summer months and now we're into the winter and all seems to be well.

I used this product in the interior sheathing of my roof. I created an air space with 2 in styrafoam strips...don't see why that wouldn't work in your scenario...just need it to breathe a bit....jmho

I have mine mounted outside to my porch ceiling. Lately it's been between -2 and 30 degrees F. It has been working perfectly the whole time.

Does this do well in small rooms with absolutely no heat during a Midwest winter? Or is this generally purchased to supplement other types of heat? Our little cabin has 2 rooms approx 15x15 ft. Outside temps are likely to be below freezing for the majority of 2-3 months or so. Thanks!

I can't see why not. If you build a plywood frame around it or fit it to the window size as you would a window air conditioning unit, it should work. Keep in mind weather could possibly enter the vent if you keep it in all year.

I also live in the NE (MA). Although the louvers close by themselves, they are not a good seal against warm air (air that you just paid to heat) escaping. If you have the fan at a high spot in the house, the pressure will be for the air to force its way out throught this loosely sealed, and un-insulated opening. It is unlikely that cold air will come down, but you will lose significant heat through this opening. The cold air will be drawn in elsewhere in your house to replace the air that you are losing here. So, with that said, here is what I did: I built a plywood box lined with foam insulation. The open bottom rim is lined with weatherstripping. It is sized to be bigger (L X W) and a bit taller than the fan assembly. It simply sits over the fan assembly in the attic during the heating season. Also, I made a "cap" of plywood, thin insulation, and weatherstripping that is held against the louvers on the living side of the fan assembly by straps that go around the fan support struts (they pass through, and partially hold open the louvers). Thus, the fan is sealed from both sides, and this prevents any warm air escape through the whole house fan. The bottom line here is that the real issue is to eliminate, as much as possible, any air that you have just paid to heat from passing through this loosely sealed opening in the most heat-loss-vulnerable part of your house. I don't know how this help forum works, but if there is a way, I can send you pics of what I have done if what I have given you is not clear.

We did not seal the attic vents etc as we have very little wind. The product worked for us.

I agree with idget. Unless you already have one of these, I'd look for a product designed for horizontal mounting. You could also just passively vent hot air into the attic and use this fan (at an attic gable vent for example) or your existing attic ventilation to send the heat from the attic to the outside.

I live in Nome, Alaska and I used this in my attic this winter to insulate a kitchen vent. I was very pleased with the result and it was easy to install.

I live in a large loft with alot of living space. We have a sliding steel door that is the only thing separating us from the elements outside. I've opted to run this inside and so far so good. I'd say as long as you have a lot of ventilation you will be just fine. Also, the wick should be cut enough to not give off any toxic soot - so keep it short.

Yes and no it can work but it may be against code. If you are venting it through the chimney you are supposed to use a steel liner. Venting it directly outside is fine though.Mine is currently venting out the chimney unlined but i will have the lining put in this spring.

We are in Australia and have been using these alarms summer and winter, lowest here would have been -2 degrees. As long as you use non rechargeable batteries they should work fine

Assuming you are insulating underside, this product should work well. I used it to insulate the attic and worked well. Follow the directions spray evenly.

I have several of this model mounted outside my house under the eaves for a number of years. They have worked perfectly even in this latest cold snap. Down south here the lowest we have experienced recently was 22 degrees. The eaves protect them from most of the rain. The heat and humidity of summer hasn't had any effect.

Well I have three of these in a 900 square foot cabin at 4000 foot elevation, I don't expect to heat the house this way, it is about freeze protection while I am gone.Never had a freezing problem yet, and it has been below zero within the last few months

Hi..unfortunately I just purchased this and have not had our winter as of yet. I would not feel comfortable assuming how it will do.
