These collectors are ideal for a number of purposes.
Can be linked in series to make bigger systems for people with larger houses or that wish to make a larger percentage of their annual hot water with solar.
Space Heating - when used in larger systems, multiple collectors can be used to assist in heating both residential and commercial buildings.
For small and large houses with limited roof space where a larger collector will not physically fit.
Use as a demonstration unit in your showroom.
Use for solar water heating in off grid cottages.
Although this is only a 20 tube collector, it produces a lot more heat than many of its competitors who charge double or triple the price.
