A. O. Smith has expanded its Cirrex line of solar thermal water heaters, now offered in 16 package systems. The all-in-one system captures up to 70% of the energy used to heat the home from the sun at a relatively low cost compared with other options. Adding more panels and a larger tank will further increase the system’s effectiveness. The Cirrex system is OG-300 by the Solar Rating and Certification Corp. (SRCC) and eligible for a federal tax credit of 30% of the total installed cost with no maximum. Additional state and local incentives may also be available.
