Q Solar ARC2Q Solar ARC2














Details:

  • The owner installed himself the 2 Q Solar ARC, each having an area of 2.1m2
  • The units are equipped with AC fans to provide high heating efficiency
  • During sunny winter days the solar air heaters provide all the necessary heating.
  • The output of both heaters is of up to 4kW (depending on sunshine)
  • The solar heaters made savings of about $4/day and paid back in about 3 years
  • During 10 years of service, the heaters will provide 1/3 price heat.
  • The real savings are larger because the fossil fuel price is increasing.
  • Q Solar were surprised to subsequently find out that the owner, Mr M. Whiters is a HVAC engineer who thoroughly tested our solar heaters and has presented this testimonial.


Large Q Solar air heater for a tourist villa in Eastern Europe

Brief:

  • Location: Eforie Sud, Eastern Europe (450 latitude)
  • Multi-storey tourist villa
  • Installation on a South-facing wall with about 15 degrees azimut offset
  • The owner said:"...very reliable, do not require maintenance and I make important savings".

Q Solar for villa

Details:

  • The task was to provide heat to a villa comprising 30m2 tourist units
  • For a unit, we installed a Q Solar ARC having an area of 6m2
  • The solar heater is equipped with an AC fan
  • During sunny days the solar air heaters provide all the necessary heating.
  • In sunny weather it delivers 60-700C air at the outlet; in cloudy weather 30-400C
  • The heating power output of a solar heater during sunny days is of about 3.5kW
  • The solar heater made savings of about $3/day and paid back in about 2 years
  • During 10 years of service, the heaters will provide 1/4 price clean heat.
  • The real savings are larger because the fossil fuel price increases.
  • The owner, Mr Cristian Mamo has presented this testimonial.

air pre-heater for burner

Details:

  • We installed a Q Solar ADU air pre-heater of 25m2 for an LPG burner .
  • The solar heater did not need a fan because the burner has a blower fan.
  • During 10 years of service, the heater could provide 1/5 price clean heat.

Details:

  • Above is a satelline image of the 307m2 solar heater
  • The beneficiary required to dry about 2 tonnes of product from 98% to 4% moisture
  • The 4GJ of net heat requirement had to be transmitted through 5.3m3/s of air
  • We installed a Q Solar ADU air heater, of 307m2
  • An LPG burner compensates during times with low solar radiation.
  • Drying tipically takes about 20 hours, therefore we have made and installed a 22 tonnes heat accumulator to allow drying when there is no sunshine.
  • The heat accumulator also diminishes the maximum air temperature from 700C to 600C not to destroy the bio-active substances of the product.
  • An LPG burner provides backup, but cannot heat the air as uniformly as the solar air heater
  • The nominal power of the solar heater is 210kW for the given conditions
  • The solar air heater can provide about 3GJ of heat ($135) per day
  • If used 3 days/week, the solar air heater could pay back in less than 2 years
  • During the 7 years of warranty, the heater could provide 1/4 price heat.
  • The director of the company, Mr A. Scott has presented this testimonial.
