Glass House Floor Capturing Solar Heat
Glass House Exterior, May 2013
for Blanke Permatop floor. The solar heat captured in the floor will be transported via warm water into flexible heating tubes embedded in floors and walls of the house (shown in lower row of photographs here).

Entire floor will be covered with the blue plastic/glass fibre mats Blanke Permat. The structure and bonding of the mats using a fast setting special powder dispersion glue Blanke GlUEMAX (6) on the Blanke Permatop main element (1, 2, 5) spares the floor screed. In other words: the mats are the bedding layer for the tiles.
The finished floor consists of the following 4 layers (from top to bottom):
air temperature outside: 19 - 22 degrees Celsius, full sun,
water temperature in pipes in floor before solar irradiation: 22 degrees Celsius,
area heated in the house (i.e. outside glass house) has about same size as glass house area irradiated by sun,
stationary water temperature at Permatop outlet: 27 - 29 degrees Celsius.
The sun heats also the aluminum construction, which in turn heats the air within the glass house, this air being much warmer than the glass house floor.
pure air convection through left door (sliding door) having an area of 6 square meters, from glass house into the adjacent 32 squaremeter room,
stationary temperature profile in glass house: 29 degrees immediately above the floor, 45 degrees near the irradiated beams of the aluminum construction.
