With the energy price hikes coming in this April, the 84% spike in the price of household gas will push up the cost of running a gas boiler above the cost of running an electric heat pump, even ...
The lifetime cost of an air source heat pump will be affected by the price of electricity compared to gas (where available), and may take two to ten years to break even. [75] The IEA recommends governments subsidize the purchase price of residential heat pumps, and some countries do so. [78]
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry. HSPF is specifically used to measure the efficiency of air source heat pumps. HSPF is defined as the ratio of heat output (measured in BTUs) over the heating season to electricity used (measured in watt-hours). [1] [2] It therefore has units of BTU ...
The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
Those building high-performance buildings, or renovating an existing building for improved energy and climate performance, often seek to reduce greenhouse gas emissions by using a low carbon energy system such an electric heat pump instead of a natural gas furnace or hot water heater. In the United States, a growing movement is seeking to ...
