Is a geothermal heat pump a better residential heating option than a boiler

If you are looking to install a new HVAC system in your home, a residential geothermal heat pump or a boiler may be ideal for your home, depending on your region and your home’s HVAC needs.

A geothermal heat pump system uses a pump to distribute the liquid, such as water or a mixture of anti-freeze and water, into the ground, where it is either cooled or heated, depending on your home’s temperature requirements.

On the other hand, like most conventional systems, a boiler needs a fuel source, usually gas or oil, which is burned to generate heat. In a boiler system, heat is transferred through water distributed to rooms via radiators, where the heat of the water is expelled into your indoor air. You should tailor your heating system to suit your lifestyle and home needs. When choosing between a geothermal heat pump and a boiler for your home, the heat pump has the upper hand in terms of efficiency. Many older boilers are only 50 to 70 percent efficient, which means 20 to 25 percent of the energy consumed ends up wasted. However, modern condensing boilers can achieve efficiency levels of up to 92 percent, with only 8% wasted. Replacing an older boiler with a newer model may significantly reduce carbon emissions. However, even the most efficient boiler cannot outstand the efficiency of a geothermal heat pump. Geothermal heat pumps have the potential to achieve up to 350% efficiency since they only use a small amount of electricity to generate 3 to 4 times more heat for use in your home.
