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 ...
The Energy Department has tips on the most efficient temperature range for homes in the winter months.
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 ...
In most settings, heat pumps will reduce CO 2 emissions compared to heating systems powered by fossil fuels. [62] In regions accounting for 70% of world energy consumption, the emissions savings of heat pumps compared with a high-efficiency gas boiler are on average above 45% and reach 80% in countries with cleaner electricity mixes.

An air-to air system can be designed to transfer heat in either direction, to heat or cool the interior of the building in winter and summer respectively. Internal ducting may be used to distribute the air. [7] An air-to-water system only pumps heat inwards, and can provide space heating and hot water. [8]
