A split system for heating is a type of heating system that is composed of two main components: an indoor unit and an outdoor unit. The indoor unit is typically installed inside the home, and it is responsible for providing the necessary heat to the living space. The outdoor unit is installed outside the home and is responsible for providing the energy to power the indoor unit. This type of system is beneficial because it allows for more efficient energy use, as the outdoor unit can be used to power multiple indoor units. Additionally, it is a great option for those who want to reduce their energy bills, as the outdoor unit can be used to capture renewable energy sources such as solar or wind power. Split systems for heating are becoming increasingly popular, as they provide a cost-effective and efficient way to heat a home.
