Energy saving and comfort with Daikin Multi+ Multi+ from Daikin is the latest innovation in heat pump technology for the home. This high-efficiency unit combines room cooling and heating with domestic hot water in a single energy-saving system. Such is the cuttingedge nature of the technology that Multi+ recently won the Best Renewable Product category in the Architects’ Choice Awards at Architecture & Building Expo. The Multi+ heat pump uses state
of-the-art technology to create a comfortable home all year round, while always ensuring a plentiful supply of hot water. Drawing on the external ambient air, Multi+ saves energy and keeps running costs down. Furthermore, user-friendly controls with app-controlled access allows settings to be adjusted to fit around individual needs. Requiring minimal space, the Multi+ is quick and easy to install, making it an ideal replacement option for domestic hot water (DHW) systems where air conditioning is also a requirement. Offered with a choice of domestic hot water storage capacities
of either 90lt or 120lt, the Multi+ heat pump can be connected to two or three air conditioners, allowing the system to be extended according to household needs. A wide range of indoor units, with several award-winning designs, are available to meet aesthetic and room space requirements, including wallmounted, floor-standing and concealed ceiling models. Programmable settings allow users to schedule system operation around their own lifestyle without compromising on energy savings or home comfort. The system also features a weatherdependent setting, where the water temperature is actually determined
automatically by the external temperature. In the event the outdoor temperature drops or rises, the unit compensates instantly without requiring user adjustment. This prevents any sudden changes in the water temperature at tap points. The Multi+ allows homeowners to set priorities for air conditioning and DHW depending on preference. Space heating and DHW heating can be set to operate simultaneously for maximum comfort and efficiency. Where cooling is required, the previously-heated DHW is used, providing cooling and hot water at the same time. The A/C priority setting ensures air conditioning stays active for maximum comfort. Additional hot water will then be heated with the electric booster heater as required. Switching to DHW priority deactivates the air conditioning while reheating the water with the heat pump, saving on energy bills. Once the DHW operation is complete, the outdoor unit can be switched back to A/C operation. The Multi+ heat pump has been engineered to provide the highest standards of reliability and efficiency, incorporating several important innovative design features, including an innovative fan design with speciallyshaped fan blades that significantly reduce sound emissions and lower power consumption. These are concealed behind an elegant front grille. Available from September 2022, the Multi+ is a clever idea for temperature regulation for homeowners who want to conserve resources and save energy costs without compromising on their home comfort.
