Ground Source Heat Pump

Product information
Advantages

The NIBE S1155 Ground Source Heat Pump is designed to make everyday living quietly comfortable and reliably efficient. Quiet operation means it won’t disturb day-to-day life. With an A+++ energy rating and the naturally steady temperature of the ground, it delivers consistent warmth across the seasons, with efficiency levels up to five times that of a gas boiler.

Fitting the S1155 is straightforward and flexible. It’s available in one output and its built-in inverter technology automatically adjusts how hard it works to match your heating needs, gently increasing or decreasing output to maximise comfort. The hot water cylinder is separate from the heat pump, which is ideal for retrofit projects where a cylinder already exists or where extra hot water capacity is desired.

The S1155 is compatible with the myUplink app, so you can check in and adjust settings from your phone or tablet whenever you like. Choose a NIBE Pro installer and you’ll get an extended warranty for extra peace of mind. Additionally, the S1155 is eligible for FlexiServ; servicing carried out by NIBE’s own engineers to keep everything running smoothly.

The system also plays well with others: it can integrate with NIBE ventilation accessories, solar inverters, pools, or an additional heat source to create a complete home solution. And because it’s eligible for the £7,500 Boiler Upgrade Scheme grant, you can reduce upfront costs as you move to low-carbon heating.

myUplink

With the help of the Internet and myUplink, you get a quick overview of the heat pump's status and the status of the heating in your home. This flexible solution allows you to easily monitor and control the heat and hot water production. If the system is affected by operational disturbances, you will be notified quickly with a push notification and via e-mail.

Filling and flushing kit used during the installation or maintenance of a ground source heat pump system. Allows filling or topping up of the brine circuit. For heat pumps up to 30kW

NIBE ROT 10

Wireless room thermostat

NIBE THS 10

This wireless sensor allows you to read the temperature and humidity in a room or climate zone using the myUplink app. On the heat pump you can see the current room temperature or change it in °C. THS 10 replaces the fixed indoor sensor. Because it is battery powered, it is easy to install. Mount the sensor in your room and connect it to your NIBE S-Series heating installation.

NIBE PCS 44

Provides passive cooling by circulating cold fluid from the ground collector loop through a building’s cooling system.

NIBE CDS 10

Wireless temperature, humidity & CO₂ sensor to be paired with NIBE S-Series controllers

NIBE ACS 45

4-Pipe Passive/Active Cooling Accessory

NIBE FLM S45

An exhaust air module that recovers heat from indoor ventilation air and transfers it to the brine circuit, boosting the efficiency of the connected ground source heat pump. It also provides mechanical ventilation, improving indoor air quality while helping reduce the size of the ground collector needed.Compatible with S-Series heat pumps.

NIBE ELK 15

Three phase back-up electric immersion heater - 15kW

NIBE RMU S40

Wireless touchscreen controller

NIBE VPB 500-1000

NIBE ECS 41

Extra heating circuit (maximum 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.

NIBE AXC 40

The AXC 40 is an accessory card paired with NIBE domestic Ground Source Heat Pumps such as the SXX56 range, used to control and communicate with additional systems, such as extra climate systems, shunt-controlled additional heat, step-controlled additional heat, passive cooling, active cooling, etc.

NIBE HR 10

A relay box accessory that acts as an interface between the heat pump and external devices, e.g. immersion heaters, cooling modules, external heat sources. It lets the heat pump turn other equipment on / off depending on the systems needs.
