  • HYDRO-THERMO IRRIGATION MAT
    Publication number: 20120111972
    Abstract: A hydro-thermo irrigation mat (10) is comprised of a base sheet (11), a water-permeable root-shielding top sheet (12), and a capillary mat (15) of absorbent material therebetween. One or more flat pliable drip tapes (18) are loosely disposed in spaced-apart relationship between the top sheet (12) and the capillary mat (15). Hot water convection tubes (25) are disposed co-axially with the drip tapes (18) but between the base sheet (11) and the capillary mat (15). The drip tapes (18) are connected to a water supply line (22) and the hot water convection tubes (25) are secured to a hot water supply line (28). Water within the mat is heated and distributes heat from the hot water convection tubes (25) substantially throughout the mat.
