This is quite the system

A mini-split splits the action of a heating or cooling system to allow different rooms to be controlled to different temperatures. These are great solutions that can actually lower one’s monthly heating and cooling costs. Ductless mini-splits can lower monthly costs because one doesn’t need to set a temperature for the whole house or building if only one room is going to be occupied. Using a number of temperature sensitive elements and thermostats, the house or building can be divided into different zones. The size and number of the zones are completely customizable based on the owner’s desires. Although larger zones will still require a lot of energy to change the temperature of relative to the outside conditions, the size is completely up to the owner. More zones that are small in size can lower the energy costs in the long run because less energy is consumed to change the temperature of a small room. There is a trade-off in cost, however, because more zones mean more sensors and equipment to install. In the long run, having each closed-off room as a zone is the most economical choice. Mini-split infrastructure is implemented in many newly-constructed buildings right off the bat. The ductless nature of mini-splits also make them a great choice for retrofitting homes that have older central heating and cooling infrastructure already installed. The only thing required for installation is a small drilled hole in the wall leading to where the outside refrigerant unit can be connected. Further, these types of systems can also be used on homes and buildings that currently have hydronic or radiant heating systems as well as older heating systems that might be using gas heat or oil heat.
