If supplemental heating is absolutely necessary, invest in an energy-efficient space heater with built-in thermostats and timers. Water Heaters Average Wattage: 4,500
For example, in winter it might be 2 °C outside and 20 °C inside, making a temperature difference of 18 °C or 18 K. If the material has an R-value of 4, it will lose 0.25 W/(°C⋅m 2). With an area of 100 m 2, the heat energy being lost is 0.25 W/(K⋅m 2) × 18 °C × 100 m 2 = 450 W.
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
