Roof snow melt systems – each has a different method to connect to the distribution system of heating in your home or building. Some types are more efficient than others in providing space cooling for the building, but it is the property of the distribution. All types of GSHP still get energy from ground loops. Which transfers the heat absorb into the internal cooling loop. It happens after that heat is what makes the difference between types.
Roof snow melt systems is probably the most commonly used is water to air heat pump. They are used for homes with forced air systems, and essentially replace traditional furnaces. Ground loop brings the heat is absorbed into the cooling loop (water portion of “air to water”). Refrigerant which is then compress and cycling in front of the fan coil unit to be sent through. The distribution duct work to the home (air section “of water into the air.” This process can also be a switch in reverse to provide cooling to the structure.
One possible design problem is the size of the ductwork. Because geothermal systems are considered as low-temperature heat source, a higher volume of air required to provide the same heating or cooling load. Roof snow melt systems this well will require ductwork larger to accommodate larger air volume.
