The Energy Department has tips on the most efficient temperature range for homes in the winter months.
Available rebates and tax credits through the Department of Energy may help pay for energy-efficient products and replace heating systems that are 15 years old or older. Funding is available for ...
Here are some ways to stay warm and save money while heating your home as you prepare for winter.
The heat pump itself can be improved by increasing the size of the internal heat exchangers, which in turn increases the efficiency (and the cost) relative to the power of the compressor, and also by reducing the system's internal temperature gap over the compressor. Obviously, this latter measure makes some heat pumps unsuitable to produce ...
A counter flow heat exchanger is the most efficient type of heat exchanger in transferring heat energy from one circuit to the other [citation needed]. However, for a more complete picture of heat exchanger efficiency, exergetic considerations must be taken into account. Thermal efficiencies of an internal combustion engine are typically higher ...
The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.
If you use electric heat, consider replacing it with a high efficiency ductless mini split heat pump system, which can lower electricity use by as much as 40%. Insulate hot-water pipes and warm ...
While a heat sink is a static object, a fan often aids a heat sink by providing increased airflow over the heat sink—thus maintaining a larger temperature gradient by replacing the warmed air more quickly than passive convection achieves alone—this is known as a forced-air system. Ideally, heat sinks are made from a good thermal conductor ...
