In episode #57 of the On the Job video series, Larry Janesky, owner and founder of Dr. Energy Saver, walks us through the installation of a high efficiency ductless heat pump.
A heat pump's job is to extract heat from the air to either cool or heat a home. During the summer, it will extract heat from the inside, and move it to the outside, to cool the living space. In wintertime, it will extract heat from the outside and move it to the inside.
Heat pumps are very efficient at extracting heat, even when the temperatures are very low outside. They will always be able to extract enough to heat up the home.
The unit being installed in this project is a split system, with an outside unit and three internal heads designed to serve three different zones of the building -- each with its own thermostat. In Air Condition mode, it has an 18 SEER (Seasonal Energy Efficiency Rating). In Heating Mode it has a 9.5 HSPF (Heating Seasonal Performance Factor) rating.
Heat is transferred between the external and external units through refrigerant line sets. The shorter the line sets, the more efficient the system is. A fan in the internal units then distributes hot or cold air throughout each of the three zones.
While it may seem like a disadvantage having the hot or cold air blow from a single wall mounted unit, a high efficiency ductless system is still able to effectively maintain comfortable temperatures because there is no heat loss or gain through the ducts. The ductless heat pump is a great option when there isn't a lot of space for bulky ductwork.
