NIBE F1345 is a powerful, flexible ground source heat pump which is available in the output sizes 24, 30, 40 and 60 kW. Up to nine NIBE F1345s can be combined in a single system to cover output requirements of up to 540 kW. NIBE F1345 has a high seasonal performance factor, and with less than 5 tonnes CO2 equivalent refrigerant volume per compressor module, NIBE F1345 does not require annual inspection. Two large compressors make NIBE F1345 perfect for properties with larger heating requirements. The compressors are switched on and off automatically for better output regulation, a longer operating range, less wear and tear and improved reliability. Thanks to smart technology, the product gives you control over your energy consumption and will be a key part of your connected lifestyle. The efficient control system automatically adjusts the indoor climate for maximum comfort, and you do nature a favour at the same time.

The NIBE HPAC 45 accessory gives your installation a high degree of flexibility. Combine your heat pump with NIBE HPAC 45 for passive or active cooling. It works, even while your system is continually heating hot water.NIBE HPAC 45 is easily controlled via the heat pump’s control panel, where both settings and monitoring are easily handled at the push of a button. This accessory’s timeless design means that it blends in well with your other heat pump equipment.
Active/Passive cooling (4-pipe). ACS 45 combined with a heat pump is a climate control system for heating and cooling houses and apartment buildings.
This accessory is used for the wall mounting of NIBE's compatible products SAM 40, SAM 41, FLM, F135 and Split installation of F730/F750
NIBE SOLAR 42 enables solar heating with your heat pump. With additional solar panels and VPBS you get a complete system.
ECS 40 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
NIBE SOLAR 40 enables solar heating with your heat pump. With additional solar panels and VPAS you get a complete system.
Extra heating circuit (recommended 80-250 m2 floor heating). ECS 41 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
An accessory that allows pool heating using heat pump. Max 17 kW. The heat pump controls the reversing valve, pool circulation pumpand any heating circuit circulation pumps via POOL 40.
Room sensor used to obtain a more even indoor temperature. RTS 40 has up to three functions:Show current room temperature in the heat pump's display. Option of changing the room temperature in °C. Makes it possible to change/stabilise the room temperature.
Communication and control. EME 20 is used to enable communication and control between the inverter for solarcells and heat pump/indoor module/control module.
With RMU 40 you can control and monitor your Nibe heat pump from another room in the house.
HTS 40 is an accessory that records humidity and temperature.
The NIBE VPB 500/750/1000 is an efficient, copperlined hot water tank with a wide range of applications which is developed for connection to a heat pump, gas or oil boiler. The NIBE VPB 500/750/1000 has insulation made of Neopor and polyester fleece, which provides low energy loss. The insulation and outer shell are detachable to facilitate installation. The NIBE VPB 500/750/1000 is designed for buildings with large hot water requirements and can be connected in parallel for maximum capacity.
A NIBE heat pump can be controlled and monitored by external Modbus equipped equipment.
NIBE PVT 40 makes it possible for your heat pump to use NIBE PVT panels as a heat source. The heat pump regulates the temperature of incoming brine in the summer, and closes the shunt valve in the winter when the temperature reaches the set value.
Passive cooling. PCS 44 is used when heat pump is installed in an installation with passive cooling.
Makes hot water priority possible at large heat pump outputs. (charging power between 15 and 40 kW), together with an SMO 10 and F1330-40. This also requires a hot water accumulator, for example, NIBE VPA.
Accessory card. An accessory card is required if step controlled additional heat (e.g. external electric boiler) or if shunt controlled additional heat (e.g. wood/oil/gas/pellet boiler), passive/active cooling 2 pipe, passive cooling 2 respectively 4 pipe or if hot water comfort is to be connected to F1345. An accessory card is also required if the ground water pump or external circulation pump is connected to F1345 at the same time that the buzzer alarm is activated.
ELK 15 is an immersion heater primarily intended for installation together with heat pump for heating. NIBE ELK 15 contains overheating protection and contactors to externally regulate the two power groups, 5.0 and 10.0 kW.
The NIBE ELK 213 is an electric heater designed for heating detached houses or smaller rental homes, as well as indirect heating of hot water. The NIBE ELK 213 can be installed together with a boiler, accumulator tank or heat pump. When installed together with a heat pump, for example, the electric heater automatically switches on to provide supplementary heating when the heating demand is greater than the heat pump’s capacity.
ELK 15 is an immersion heater primarily intended for installation together with heat pump for heating houses or
Electric boilers for additional heating for ground source heat pumps.
Energy measurement kit for indoor unit.
Auxiliary relay HR 10 is a connection box housing a contactor and a rotary selector switch. It is used to control external 1 to 3-phase loads such as oil burners, immersion heaters and pumps.
Combination valve for filling up the brine. Including insulation.
