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.

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 ECS 40
Allows the heat pump to control a second heating circuit (zone) with a different temperature requirement. For up to 80 m² of underfloor heating
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.
