Due to the way air source heat pumps work, they can bring major cost savings in some circumstances. They use the air outside as a natural heat source, as opposed to actually generating heat like electric, coal-based or gas fired systems. Of course, they do still use electricity to run, but produce more heat energy than the energy they consume.
Whether you’ll see significant savings will depend on several factors, including the type of system you're replacing, the efficiency of the air source heat pump installed, and how well insulated your property is (which we’ll address in the cons).
Lower Environmental Impact
In using less energy in the heating process, you’re also lowering CO2 emissions, so in the same way they save you money, ASHPs also reduce your carbon footprint.
