Emma Jonson What does humidity non-condensing mean?
If the relative humidity is high enough, and the air temperature is high enough, the water vapor will condense on cooler surfaces. This is the dew you see in the morning. Since dew typically has lots of atmospheric “dirt” in it, it’s quite conductive, more so if you live near the ocean. Non-condensing means “No dew”.
Is 85% humidity high or low?
Experts generally agree that the ideal indoor humidity levels for comfort and for avoiding health effects are between 35 and 60 percent. When you’re spending time in a home or workplace with humidity levels in excess of 60 percent, it’s increasingly likely that you will experience certain health issues.
What is condensing humidity?
The “condensing humidity” is the value of relative air humidity at which, when it is exceeded, the vapour condensation will occur on the surface having some specific temperature. The introduction of condensing humidity provides direct normative assessment of the temperature field calculated for some construction.
What does 60 humidity feel like?
At 60 percent humidity, 92 degrees can feel like 105 degrees. And, according to the National Weather Service, that can bump up yet another 15 degrees if you’re out in direct sun. Most people agree that a hot day becomes increasingly unbearable when it’s humid out.
What is the difference between a condensing and non-condensing tankless water heater?
Condensing tankless heaters use a dual heat exchanger design to make maximum use of the energy delivered to the system. Non-condensing tankless water heaters utilize a single heat exchanger so they vent more heat in the exhaust gases. Smith tankless hot water heaters have built-in freeze protection.
How do I protect my camera with humid weather?
5 Ways to Protect Your Camera in High Humidity Conditions
- Acclimate Your Camera.
- Silica Gel Packs.
- Keep a Lens Cloth With You.
- Dry Your Equipment.
- Avoid Changing Lenses.

What is the difference between condensing and non-condensing humidity?
Non-condensing moisture remains as water vapour exerting its own partial pressure to the atmosphere and, in an enclosed, non-condensing environment – ie at a temperature above the dew point – very approximately complies with the gas laws (Charles’and Boyle’s).
Is 90% humidity uncomfortable?
Forecasters watch the dew point, not relative humidity, because hot air can hold more moisture than cool air. At 90 degrees, we feel uncomfortable at dew points of 65-69 degrees. Dew points above 70 degrees feel oppressive.
Does a non-condensing tankless water heater need a drain?
Non-condensing tankless water heaters utilize a single heat exchanger so they vent more heat in the exhaust gases. A condensing tankless water heater will need a condensate drain, while a non-condensing water heater will not.
