Frequently Asked Questions
This section is continually expanding; this is just the beginning!
How do you keep it warm in the winter?
Any source of radiant heat works best. A camping propane heater (ex: Mr. Buddy Heater), a gas fire ring, a vent-free gas fireplace log, are great solutions. Most of these have catalytic inverters so your air stays clean and safe. I recommend you buy a carbon monoxide reader that will alert you if the air is unsafe to breathe. This has never happened. Because the walls are breathable, fresh air is always the air you have inside.
Another solution is radiant floor heating. There are a few designs for that, contact me if that is what you want to do, and I will offer you some suggestions.
How warm does it get?
As warm as you like it! When it is 0°F outside, it will become 75°F inside in 30 minutes. It usually rises 30°F in temperature every 10 to 15 minutes, depending on how high you turn on the heat.
How is it possible that it stays so warm?
The PleniSphere® is equipped with a double-walled air pocket technology. Two very high-quality canvas walls overlay each other, with a 4" pocket of space in between. The wall of air acts as an insulator and holds the heat inside.
How does it hold up in the snow?
This snow melts away as soon as it lands on the roof. The warmer air inside is sufficient to prevent any snow accumulation. I have even been gone for days at a time when there was a snowstorm, came back to a blanket of snow on the ground, and the PleniSphere® was free of any of it. I simply left the heater running on very low.
Do the PVC pipes break or crack in below freezing temperatures, or when exposed to sunlight or high winds?
The PVC pipes that make up the frame are covered at all times by two layers of canvas. This prevents any sunlight from reaching them directly and keeps them separate from the outside. When the structure is heated on the inside, it keeps the pipes warm. The pipes can sustain high winds and will bend rather then break. No pipe has ever broken or cracked.
How much wind can it withstand?
When properly anchored to the ground, the materials and construction are rated to withstand up to 80 mph winds. Depending on the soil that you are in, you use up to 5' long rebar stakes or 3' steel stakes to anchor your structure firmly on the ground. This will give it tremendous structural stability.
How much condensation builds up on the walls?
None! The walls are breathable. Unlike nylon tents, or any poly material, these are 100% cotton, yet highly durable quality canvas.
How does it perform in the rain?
Because the canvas has been treated with a non-toxic water resistant treatment, when water lands on it, it is immediately repelled. Additionally, only the outer layer is ever exposed to water. The inner layer stays dry. Even several days of torrential rains will not affect it. I have lived in Ocean Shores, a town on the coast of Washington state where it rains 80" per year to prove it!
