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. Wondering what temperature to set your thermostat at? This is the ideal heat setting
The Energy Department has tips on the most efficient temperature range for homes in the winter months.
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.
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 ...
Some systems use a heat pump to help charge and discharge the storage during part or all of the cycle. For cooling applications, often only circulation pumps are used. Sorption and thermochemical heat storage are considered the most suitable for seasonal storage due to the theoretical absence of heat loss between charging and discharging. [5]
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 ...
