    SPLIT is a system for heating, cooling and producing hot water for small houses. The system consists of an outdoor module (L8 SPLIT/L12 SPLIT), which utilises the energy in the outdoor air and sends it to the indoor module (HM 8-12 SPLIT), which takes care of the regulation and heat distribution in the house.
