System Overview

floor design and sizing the harvest radiant system is considered a low temperature radiant system as such, there are a few practices that can help get the best performance out of a lower temperature radiant floor use longer loop length than typical to help achieve a low return temperature, e g , 250 500 ft length use a “double back” layout, i e the warm supply pipe is always next to the cooler return pipe to achieve a uniform temperature across the floor the higher the radiative transfer capacity of the floor, the better system performance and efficiency will be in addition, the calculated heating capacity of the floor should always exceed the design load of the building calculate the heating capacity of the floor floor capacity = heat flux (btu/sqft/hr) heated floor area (sqft) \ plumbing overview \ wiring overview
