The NORDIS ULTIMA MONO SPLIT HLT9MONO-S / HLT-9-250-3S is a complete home comfort system providing space heating, cooling and domestic hot water production in one integrated solution.

The set combines the HLT9MONO-S outdoor unit with a floor-standing HLT-9-250-3S indoor unit incorporating a 250-litre domestic hot water tank. Its All-in-One design saves valuable installation space and eliminates the need for a separate hot water cylinder.

The heat pump delivers up to 9.52 kW of heating capacity at A7/W35. Full inverter technology continuously adjusts compressor output according to the building’s actual demand, helping maintain stable indoor temperatures while reducing unnecessary electricity consumption.

The system uses natural R290 refrigerant with a global warming potential of only GWP 3. R290 supports high energy efficiency and enables a leaving-water temperature of up to 75 °C.

This makes the system suitable for new low-temperature homes with underfloor heating as well as renovated buildings and radiator systems requiring higher water temperatures.

At a 35 °C water outlet temperature, the system achieves an A+++ energy class and a SCOP of 4.85. At 55 °C, it achieves an A++ class and a SCOP of 3.65. Heating operation is available at outdoor temperatures down to -25 °C.

The integrated 250 L domestic hot water tank is manufactured from durable Duplex 2205 stainless steel. DHW priority control heats the tank when required, while the automatic disinfection programme supports safe and hygienic hot water operation.

The indoor unit incorporates a two-stage 9 kW backup electric heater with 3+6 kW control. Factory-integrated components include a Grundfos circulation pump with a 9 m head, Vortex flow meter, LK Systems three-way diverting valve and two 5 L expansion vessels.

A modern 7-inch colour touchscreen provides clear control of heating, cooling and domestic hot water. Built-in Wi-Fi enables remote operation, while weather-compensated heating curves automatically adjust water temperature according to outdoor conditions.

Dual-zone control can supply different water temperatures to two circuits, such as underfloor heating and radiators. Smart Grid Ready functionality supports integration with intelligent energy-management solutions.

The system is designed for quiet residential operation. The outdoor unit has a sound pressure level of 39 dB(A) at one metre, while the indoor unit produces only 20 dB(A).
