About and SolarBair

I started this site because good information about solar and hydronic heating is hard to find. To design and install durable, efficient and cost effective heating systems, good information is essential. Much of the literature you will find is provided by manufacturers and sales people and is biased towards their products. Information from other sources is often inconsistent or context dependant. Data from the SRCC (Solar Rating and Certification Corporation), while hopefully impartial, needs to be interpreted. With this site I hope to provide good, impartial information covering a wide range of solar thermal and related topics. A lot of the information out there results in only a shallow understanding. This site will cover the basics but will also include in-depth information about specific system components. I will conduct the search and distill the information into a presentable form for the visitors of and

As a user of this site you should know I am a master plumber and hydronic heating professional with a mathematics degree and over a decade of experience in the field. I am available to do consulting, design and local installation work for a negotiable fee.
