System S6 is a 6kw output split air-to-water heat pump system for domestic climate control. Created by Dimplex, it is ideally suited for energy efficient heating and hot water in new build properties. It has been designed as a low carbon, high efficiency system for detached and semi-detached houses, with plug and play installation and simple controls for intuitive operation. Utilising intelligent inverter technology, the system can operate in outdoor temperatures down to -25°C producing hot water up to 60°C. The solution uses refrigerant R32, which has a low GWP. This creates a more environmentally friendly solution which improves the building's carbon footprint. The indoor unit has a compact footprint of 60 x 60 cm and contains everything required for climate control within the dwelling, including a 210l hot water cylinder.
