Heat Pumps for Heating and Cooling The following guidelines are suggested in applications where a heated floor slab will be used to deliver heat derived from a hydronic heat pump: • The system is generally designed for heat output of 20 Btu/ hr/ft2 from a slab. • Tube spacing within the slab should not exceed 12 inches (6 inches preferred). • Slab should have a minimum of R-10 underside insulation. • Tubing should be placed at approximately 1/2 the slab depth below the surface. Doing so decreases the required water temperature need for a given rate of heat output. Lower water temperatures improve heat pump performance. • Any finished floors used should have a Total R-value of 1.0 or less Advantages The heat floor slab provides two important benefits: firstly, it minimizes the on-off cycling of the heat pump; secondly as the area of the heat release becomes very large, the required flow temperature of the water through the pipes becomes much less than that required by conventional radiator systems. The other advantages are: 79PDF Image | Heat Pumps for Heating and Cooling
