Residential Energy Recovery Radiant-Heated Slab System for Melting Snow

Abstract

This paper introduces the feasibility of a flue gas energy recovery system that applies recovered waste energy to the proposed energy recovery radiant-heated slab system (ERRHSS). Through application of a runaround coil system to a 32.2 kW indirectly fired natural gas residential furnace, energy was transferred outdoors to melt snow on a radiant-heated slab by way of cross-linked polyethylene (PEX) tubing and a small circulation pump. A full-scale model was constructed and its overall performance resulted in an adequate heat supply to melt the snow from a
