NIBE S1155-25 Ground Source Heat Pump

Description

NIBE S1155 is an intelligent inverter-controlled ground source heat pump without an integrated hot water tank, which makes it very easy to place in spaces with lower ceiling heights. A separate hot water tank is easily selected based on the home's specific hot water needs. Thanks to the heat pump automatically adapting to the current heat demand, optimized energy savings and consistent indoor comfort are achieved all year round. With long experience in power-regulating ground source heat pumps and one of the market's widest ranges, NIBE is a leading player in modern inverter technology.

NOTE! Velltra assures that all NIBE products marketed and sold by us are manufactured in Sweden and contain components of the highest quality, especially adapted to the Nordic market and its challenging climate.

Perfect adaptation to needs and flexible installation

The leading inverter technology provides continuous adaptation of the output to the property's conditions. Since the unit lacks a built-in water heater, it is an excellent fit where ceiling height sets limits, while the option of a separate hot water tank makes it easy to meet greater needs for domestic hot water.

Top-performing energy efficiency and economy

The NIBE S1155 delivers a high annual heat transfer coefficient (SCOP), resulting in a very low operating cost over time. With an efficiency in the absolute top class (A+++ at both 35 °C and 55 °C) and a high COP value of 4.68 at B0/W35 according to EN 14511, stored solar energy is extracted from the ground, rock or groundwater in an exceptionally gentle and profitable way.

Connected home automation and user-friendliness

The integrated S-series technology transforms the heating system into a natural part of the connected home. Equipped with a clear color touchscreen, integrated wireless connectivity and support for smart wireless accessories, the climate can be optimized automatically using, among other things, weather forecast control. Via myUplink, full overview and smooth control are provided directly on a smartphone or tablet, and the system can also be integrated with voice assistants for convenient everyday use.

Warranty and security

Please note that the manufacturer’s full warranty is not applicable for units bought in Sweden and installed outside Sweden.
