Reduce Your Energy Bill With an Air to Water Heat Pump
If you’re looking for a way to reduce your energy bill by approximately two thirds, an air to water heat pump may be the solution for you. This type of heating system can operate at ambient temperatures as low as -13o. It can also replace 70 to 80% of your fossil fuel need.
Replace 70% to 80% of the fossil fuel requirement
It is clear that heat pumps have a critical role to play in building heating decarbonization. The energy supply sector is responsible for 35% of the global greenhouse gas emissions. This includes the use of fossil fuels for space heating, commercial and residential. Achieving the Sustainable Development Goals requires a shift toward clean fuels and lifestyles. Heat pumps can help reduce emissions in most regions.
Approximately 70% of all space heating energy in the United States is generated by fossil fuels. However, air to water heat pump advances in high efficiency and low temperature HP technologies have the potential to reduce these fossil fuel usage rates to 1% or less of all heating energy. In fact, a flexible pathway could enable the decarbonization of more than one third of the total fossil fuel-based space heating by 2050.
There is an opportunity to leverage existing fossil fuel infrastructure to support increased penetration of electric heating. In addition to increasing the penetration of clean energy, this strategy avoids the construction of new generation, associated transmission and distribution networks, and permits for some challenging projects. For example, the fossil-free gas system has the potential to avoid the buildout of 80 gigawatts of new generation and related infrastructure. These benefits reduce the risks of safety, security, and service interruptions for customers.
Using existing heating-driven fossil fuel delivery capacity, a peak-limited scenario can decrease the amount of fossil fuel-based heating to less than 3%. This would be achieved by maintaining a given fraction of current fossil fuel heating capacity in dual source systems (DSS) that include new heat pumps.
Advances in low-temperature HP technology have the potential to significantly reduce the amount of air to water heat pump fossil fuel-based heating in DSSs, as well as to expand the deployment of peak-limited HPs to 75%. As a result, the remaining 20% of heating capacity could be all-electric. If further advances are made in the next several years, the DSS capacity can be reduced by more than half.
Electrification is a powerful way to drive deeper decarbonization of the heating energy supply. However, there are many factors that need to be considered. Among them are the costs of installing heat pumps, the main running costs of heat pumps, and the availability of electric infrastructure.
Leave fossil-fuel equipment in place when replacing an existing furnace or boiler
Choosing to replace your old furnace or boiler with an electric heating appliance is an environmentally friendly and economical choice. There are several benefits to this type of heating system, including lower utility bills, lower carbon emissions, and a longer life expectancy. It also can help to reduce air pollution by generating less heat. However, if you are replacing your existing equipment with a new model, you might want to leave the fossil fuel equipment in place.
The most significant impact of using fossil fuels for home heating is that they produce a lot of greenhouse gas emissions. Natural gas, for example, is the dominant source of home heating energy in Canada. Fossil fuels are also used for cooking, hot water heaters, and other household appliances. In addition to producing air pollution, all of these products create large amounts of greenhouse gases, which contribute to climate change. These gas emissions are especially damaging because methane is much more potent than carbon dioxide.
The International Energy Agency (IEA) has recommended global fossil-fuel boiler bans in 2025. However, most old buildings are already required to follow zero-carbon-ready building energy codes, which require the installation of efficient heating equipment. Even new construction projects must comply with these requirements.
