Which is Cheaper, Air Source Heat Pump or Gas Furnace Heating?

Which is cheaper, air source heat pump or gas furnace, depends on many factors, including regional electricity prices, natural gas prices, house insulation performance, etc. In general, air source heat pumps are usually more economical than gas furnaces in long-term operating costs.

1. Operating cost

The air source heat pump system is driven by electricity and absorbs heat from the outside air for heating. Its energy efficiency ratio (COP) is usually around 3-4, that is, 1 kWh of electricity can generate 3-4 kWh of heat energy. In contrast, the operating cost of gas furnaces is higher and is directly affected by natural gas price fluctuations. For example, in the measured data in Taiyuan, Shanxi, the operating cost of air source heat pumps is about 326.4 yuan per month, while that of gas furnaces is about 2,800 yuan per month.

2. Initial installation cost

The initial installation cost of the air source heat pump system is higher, but its service life is longer, and the design life of core parts can reach 15 years. The initial installation cost of gas furnace equipment is relatively low, but its service life is shorter, usually not more than 7 years.

3. Environmental protection and safety

Air source heat pumps use clean energy, have no emissions, are more environmentally friendly and safer. Gas furnaces produce greenhouse gases such as carbon dioxide during combustion, which pollute the environment and pose safety risks.

4. Long-term economic efficiency

Although the initial investment of air source heat pumps is high, due to their low operating costs, they may be more economical in the long run, especially in areas where electricity is relatively cheap. In addition, the cost of air source heat pumps is easier to predict and control.

Air source heat pumps are usually more economical than gas furnaces in long-term operating costs, especially for families with low electricity bills and environmental protection. However, the specific choice still needs to be considered comprehensively based on individual family circumstances and local energy prices.
