At the core of the Q Solar air heaters, the special permeable solar radiation absorbers (SRA) transform solar radiation into heat and efficiently transfer it to the air which passes through their pores.
The SRAs are used in more than 50 Q Solar heaters models, each suitable for a different application. The Q Solar Optimized Design provides the most efficient and economical heater for that application.
As seen above, both efficiency and the raise in air temperature T* are considered in the analysis of the solar air heater performance and used in the Q Solar Optimized Design.
Since Q Solar heaters have high efficiency and low cost, they produce the lowest price heat.
