Can some of you weigh in on what you feel is the best wired outdoor reset and why? I am currently installing my building envelope and need to plan for this penetration now.I will be linking this up to an Air to Water Heat Pump heat plant to be used with radiant hydronic ceiling panels.Many ThanksSeanSee More
"It could be that the ridge vents themselves have caused an increase in humidity. Did you remove standard box vents when you installed the ridge vents? Do the ridge vents have a fabric bug screen?

This group will focus on the issues associated with incorporating renewable energy sources like Solar PV, Solar Thermal, Geothermal, Small Wind, Small Hydro into the Residential Energy Efficiency and Sustainability business model.

"Various studies have indicated very little air flow along surface of duct (for ventilation - have not studied forced air). So if this is for venting, the screws would not be an issue at all as the pressures are to low.
