This is a general guide but there are several factors that affect the efficiency of a solar thermal system:
- Domestic Hot Water: 10 tubes per person
- Hydronic Radiant Floor Heating: 2-4 tubes per 10 sq. ft. area
- Swimming Pool Heating: 3-4 tubes per 1 sq. ft. area at 40-50% Coverage
- Solar Hot Tub Heating: 50-75 tubes for up to 450 gallons
- Insolation Level
- Collector Orientation
These factors must be taken into consideration when designing the system. Our engineers are well trained to notice these points and design the system to compensate for these and other impediments that might hinder the performance of the system.
