A 44 m2 Low Flow Solar System for Domestic Hot Water

Abstract

Publisher Summary This chapter discusses a solar system for domestic hot water that has been constructed at a boarding school called Sofartsskolen situated in Sonderborg, Jutland. The system is the first in Denmark designed for larger applications than single-family houses and making use of the attractive low-flow principle based on lower flow, smaller piping, and stratification in the storage tank. It is also among the first internationally operating systems based on this principle. As in most larger solar applications, the system supplies heat for both domestic hot water use and considerable heat losses in the circulating piping of hot water. The system has functioned without problems until now and is currently being monitored. The monitoring period will clarify the advantages and disadvantages using the low-flow principle for larger systems. The system is of significant importance for the future design of larger solar systems in northern countries.
