Wondering why it s more humid upstairs than downstairs.
In floor heating muggy.
High or low indoor humidity can damage the floor in different ways.
Indoor air that s warm and moist humid is less dense than dry air which makes it rise.
Some basements just have a dirt floor and water vapor can easily enter the basement through the soil.
How it works hydronic underfloor heating uses hot water to circulate through the pipes.
This ultimately results in wasted energy and an overwhelmingly muggy atmosphere containing airborne allergens.
There are no drafts with this type of heating except for building envelope infiltration and or mechanical ventilation.
Without dehumidifier on muggy days i m sure rh level would be at least 65 in basement.
In our case the air is the tea and the moisture level would be those sugar crystals.
Well it s actually normal to a certain degree.
Unlike conventional forced air furnaces radiant floor heating has no ducts or radiators to contribute to dust collection.
However the outside rh and indoor humidity levels can vary dramatically especially during the heating season.
Think about when you ve experienced a hot muggy day.
As you heat cold outside air the rh drops significantly.
However if the relative humidity is greater than 5 then.
Hotter air can hold more moisture than cold air so once hot muggy air cools it becomes even more humid and muggy.
As it is i m on the lowest speed of a three speed dehumidifier and i have that on a timer so it s not on all the time.
Humidity related wood floor problems.
So here s a good rule of thumb.
The floor is warm to the touch.
To prevent this from happening cover the floor with sheets of 6 millimeter plastic.
Overlap the seams of the plastic to prevent moisture from getting through and attach the plastic to the walls with tape or staples.
I m pretty lucky here it s not that severe but if i can lower that by 15 20 i can save alot on electricity.
In hydronic heating systems the warm air is being lost through single glazed windows and other openings.
