Heating systems for residential houses have been developed
using advanced architectural techniques. In addition, essential
factors - the regional climate, thermal conditions of the building,
lifestyle, and heating facility – affect the selection and operation of
the heating system.
A radiant slab heating system can operate transmitting power
quietly and efficiently with no noise at low costs of the initial
investment and with low maintenance. The floor temperature is
only slightly higher than the setting point so that the system can
use lower water temperature and be connected to other heating
systems.
Studies on heating methods are being carried out on the correct
supply flow rate and temperature to maintain a pleasant indoor
temperature. However, from the findings of these studies, dynamic
properties and heat amount changes vary with each method, and
indoor energy analysis is consequently becoming more important.
In the study of a floor radiant heating system, Friedlander [1]
and Adelman [2] recommended the outdoor reset control method
which controls supply hot-water in inverse proportion to a change
of outdoor temperature with continuous hot-water circulation.
