TC.230.07.MAR2014 Solar Boiler™ Technical Specifications; page 1 of 8 Solar Boiler ™ Solar Domestic Hot Water System Technical Specifications SRCC Certification # 100-2006-005A – CSA # 243150 Thermo Dynamics Ltd. 101 Frazee Avenue Dartmouth, Nova Scotia Canada, B3B-1Z4 Tel: (902) 468-1001 Fax: (902) 468-1002 Email: [email protected]www.thermo-dynamics.com A. General Information 1.0 System Description: The Thermo Dynamics Solar Boiler™ system is a revolutionary concept in solar domestic water heating systems. It is a solar preheat system using the external Side- Arm™ heat exchange system pioneered by Thermo Dynamics and the Micro-Flo® collector system for unsurpassed heat exchange efficiency. 1.1 Warranties: Thermo Dynamics Ltd. warranties the Micro-Flo® collectors and Solar Boiler™ heat exchange module for ten (10) years, all other components are warranted for one (1) year. 1.2 System Options: Micro-Flo® collectors are available in 1.2m x 2.4m, (4' x 8'). The Solar Boiler™ system can have either one or two Micro-Flo® collectors installed. Collector mounting hardware is available for either sloped or flat roof installations. 2.0 Product Use: Year round domestic and small commercial hot water preheat systems. Ideal for remote locations where power electrical power consumption is limited or unavailable. 2.1 Geographic and Climatic Limitations: None. Freeze protection, using food grade antifreeze, protects the system in cold cli- mates. In hot climates over temperature protection is provided by thermostatic system shut off.
