A heat pump is a heat exchanger system many households use as a cheaper alternative to a conventional furnace. The difference between a furnace and a heat pump is that it does not require any energy source other than electricity. 

There are three types of heat pumps according to the principle:

  • Air source heat pump
  • Water source heat pump
  • Geothermal heat pump

Air source heat pump

This type of heat pump uses two sets of copper coils. These two coils exchange heat by condensation and evaporation. It is a unique thing about heat pumps; they are used in summer and winter. The device only needs to reverse the heat exchange cycle between the two sets of coils. It is also the reason heat pumps are cheaper alternatives for furnaces. 

Because a conventional furnace burns fuel to produce heat, naturally, the energy consumption bill rises. 

You can get several types of heat pumps at goodman heat pumps for sale.

  • Air-to-air heat pump: It exchanges heat between indoors and outdoors. It is suitable for any household.
  • Air-to-water heat pump: Exchange heat between the radiator and outdoor air. It is suitable for houses with floor heating systems.

Water source heat pump

These heat pumps are suited for households close to any natural water body or underground hot water tank. Here the working principle is the same air source heat pumps. But here, waterworks as a heat exchange medium. 

Here, instead of copper tube coils, copper pipes are used to make large heat exchanges submerged in water. The pipeline stays a minimum of 8ft underwater. The temperature in the deepwater stays relatively throughout the year. Hence, water acts as the perfect medium for heat exchange. Often underwater systems are cheaper to install. But they are more expensive than air-source heat pumps. Water source heat pumps are of two types. 

The goodman heat pumps for sale have all the available systems in the market. 

  • Closed-loop system: Here, liquid refrigerant is used to fill up the copper pipe. Which is fitted in a closed-loop coil. 
  • Open-loop system: Here, open-ended pipes and pumps circulate water to exchange heat.  

Ground source heat pump

This heat pump uses natural ground temperature to dissipate heat. As the water bodies, the underground temperature is also stable throughout the year. Therefore, plastic pipe coils are embedded underground to act as a heat exchanger. 

There are multiple types of Ground source heat pumps:

  • Closed-loop system: Here, chemical antifreeze solutions circulate inside a closed coil to disperse heat underground. These are installed in a horizontal or vertical configuration, wherein order the coil is parallel or perpendicular to the ground surface.
  • Open-loop system: Here, a water pump circulates water from a nearby water body through an underground pipeline to dissipate heat and exchange heat inside the household. 

These three types of systems have their pros and cons. Like, underground heating systems are more efficient than air-source systems but less efficient than water-source systems. But underground systems installation is the most expensive.
