| Abstract: | A methodology is outlined that has been used to study the sensitivity of the performance of portable electric and kerosene space heaters to several parameters, including: the price of fuel for the conventional central heating system, the price of portable heater fuel, the thermal integrity of the structure, the size of the room that the portable heater is used to heat, the setback temperature for the central heating system, the duration of use, rates of air exchange with other spaces, and geographic location. Results are used to identify the conditions for which portable heaters are most beneficial and to which parameters the savings are most sensitive. The results show that savings are most sensitive to the thermal integrity of the structure, the price of fuel for the conventional heater, the thermostat setting during setback, and the duration of use of the portable heater. Payback periods for portable heaters are found to range from several months to more than six years. |
