Thermostat Start Control of SolarVenti® by thermostat

The SolarVenti® is so good that it is able to start on bright days even that there might not be any sun.

If heating contribution is important rather than just ventilation, blowing in cold or at least not warm air from outside can be avoided with tis thermostat setting it at the desired start temperature.

Humidity stop
fugtstop stainless

Patent app. ”Humidity stop”, which also function as a counter valve.

Besides beeing less expencive than a traditional counter valve you get more advantages:

  • Prevents flow of air from the house back into the collector
  • Decreases wind draft from outside (from the collector when it is not in operation)
  • Humidity Stop makes no noise
  • Prevents condensation dripping from the valve if there are pipes on a cold loft
  • Prevents intake of dust during a building process
  • Made in durable stainless steel and resistant to temperature

The Humidity stop is now standard in all SolarVenti® systems.
