Solar and Pellet Heating Systems

Pellet heating systems for single-family houses are §currently a strongly growing market; however pellet §heating is seldom installed together with solar §heating, though it is a promising combination. The §present book is based on the author's doctoral §thesis written at KTH, the Royal institute of §Technology in Stockholm, Sweden and investigates how §electrically heated single-family houses can be §converted to pellet and solar heating systems. There §is a strong focus on system design and how to design §and operate the systems so that the annual system §efficiency and solar gains can be maximized. §Technologies for increasing the solar gains are DHW-§units for hot water production and the use of hot §water for heating of dishwashers and washing §machines via a heat exchanger instead of electricity §(heat-fed appliances. The possible reduction of CO-§emissions by combining pellet heating with solar §heating are also investigated. The method is based §on measurements modeling and system simulations §using the dynamic simulation program TRNSYS.
