NIBE™ F1155 GROUND SOURCE HEAT PUMP HEAT PUMP WITH ROCK, GROUND OR LAKE AS HEAT SOURCE. • Optimal annual heating factor thanks to the inverter controlled compressor. Minimal operating costs, the compressor increases/ decreases speed according to the prevailing heating demand. Software controlled circulation pumps that supply the heat pump and the heating system with suitable flow. It also gives you the opportunity to control comfort in your home no matter where you are by using NIBE UplinkTM. Display unit with large and easy-to-read colour screen (TFT). – User friendly control system. – cons and text for clear information about status, I temperatures and settings in the heat pump. – indoor sensor included. High temperature range. – upply temperature 70 °C S – eturn line temperature 58 °C. R Integrated clock with real time function for scheduling changing of hot water and indoor house temperature. Prepared for (with accessory): – ool heating (POOL40) for both pool and spa. P – ontrol of up to four heating systems (ECS40/ECS41). C – tatus and settings via NIBE UplinkTM or via SMS S (SMS40). – ctive / passive cooling with PCM 42 or HPAC 40. A Easy to remove the cooling module. NIBE F1155 NIBE™ F1155 is a heat pump for heating small houses and smaller multi-occupancy houses. The heat pump automatically adjusts itself to the output requirement of the house during the year. When more heat and hot water is required, the output increases, when not so much is needed, it drops to a lower speed. This results in optimal savings as the heat pump always runs at the correct performance all year round. Both the low energy circulation pumps and the flexible hoses are integrated, and the brine circuit can be connected on either side. Particle filter supplied. The heat pump can be connected to an optional low temperature distribution system. e.g. radiators, convectors or under floor heating. An integrated 7 step 7 kW immersion heater connects automatically as necessary. (can be connected to a 4-step 9 kW immersion heater). F1155 is constructed on a robust frame with durable panels and effective soundproofing for the best possible comfort. All panels are easy to remove for easy access when installing and for any servicing.

INSTALLATION METHOD Rock The heat pump collects a proportion of the rock’s stored solar energy via a collector in a bore hole in the rock. Brine to heat pump Brine from heat pump Sleeve pipe Ground water level Active borehole (water column in rock) Surface soil The heat pump obtains a proportion of the ground's stored solar energy via the buried ground collector. The heat pump obtains a proportion of the water’s stored solar energy via the lake collector that is anchored on the lake bed.

HOW DOES F1155 WORK? Principle of operation F1155 consists of heat pump, immersion heater, low energy circulation pumps and control system. F1155 is connected to the brine and heating medium circuits. The heat from the heat source (rock, soil, lake) is taken up via a closed brine system in which a mixture of water and antifreeze circulates. In some cases, the ground water can also be used as heat source. An intermediate heat exchanger should be used to protect the heat pump in such cases. In the heat pump evaporator, the brine (water mixed with anti-freeze, glycol or ethanol) releases its energy...

GOOD TO KNOW ABOUT NIBE™ F1155 Transport and storage F1155 should be transported and stored vertically in a dry place. Position the heat pump on a firm base, preferably on a concrete floor or foundation. Use the heat pump’s adjustable feet to obtain a stable set-up. Install with its back to an outside wall, ideally in a room where noise does not matter, in order to eliminate noise problems. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem. Wherever the unit is located, walls to sound sensitive rooms should be fitted with sound...
