ZEWOTHERM at GET NORD: Expanded ZEWO ALPHA Range and Simplified Installation Solutions

ZEWOTHERM is participating in the GET NORD exhibition in Hamburg (19–21 November, Hall A1, Stand A1.140) with a focus on air-source heat pumps and comprehensive energy systems for residential and public buildings.

Expanded ZEWO ALPHA Range

The fully modulating ZEWO ALPHA family of air-source heat pumps complements the well-established ZEWO LAMBDA series. Currently available models are G7 (7 kW) and G15 (15 kW). For 2027, ZEWOTHERM plans to produce units with capacities of 10, 16/18, 21, and 35 kW, covering the range from single-family to multi-family homes.

ALPHA series heat pumps operate on the natural refrigerant propane (R290), provide both heating and cooling, and achieve a flow temperature of up to 75 °C. Thanks to their low unit height, the models are suitable for space-constrained installation areas: for example, the ZEWO ALPHA G15 is only 110 cm tall.

Simplified Installation: PowerBox ALPHA and Split Copar Storage

To reduce on-site work, ZEWOTHERM integrates all connection and control equipment into a pre-connected module called ZEWO PowerBox ALPHA. Tasks are divided among specialists: the heating crew connects the hydraulic components, while the electrician powers up the PowerBox. The package includes a matched hydraulic station with a built-in circulation pump, a changeover valve, and an electric auxiliary heater.

The split combined storage tank ZEWO Copar addresses the challenge of narrow basement openings and difficult access routes: the tank consists of two sections assembled directly at the installation site. Capacity is 500 or 800 L; the storage tank is compatible with both the ALPHA and LAMBDA families. Domestic hot water is heated in flow-through mode via a stainless-steel heat exchanger.

Solutions for Higher-Capacity Buildings

For higher capacity requirements, the stand will feature the ZEWO LAMBDA EU35L: modulation at A2/W35 in the range of 7–37.7 kW, SCOP of 6.06 in low-temperature mode. Cascading allows the unit to be used in large residential buildings and district-level solutions.

The prefabricated energy station ZEWO PowerCube is designed for serial heating replacement in municipal buildings, residential districts, and multi-family housing. The heat pump, storage tank, hydraulics, and control system are integrated into a single unit installed outside the building; on site, only connection to the building's utility networks remains.

Comprehensive Energy Systems

In addition to heat generation, ZEWOTHERM will present components for heat and energy supply at GET NORD: underfloor heating systems, domestic hot water systems, apartment stations, photovoltaic installations, battery storage, and the ZEWO Dynamics energy management system. The exhibition is complemented by information on energy services — thermal contracting, financing, and electricity tariffs for tenants.
