Heat pump with a wide performance range
The new Hargassner air-to-water heat pump Airflow-M with a capicity range of 5 to 20 kW is suitable for detached and semi-detached houses as well as for renovation projects. It heats or cools as needed and delivers highly efficient performance. Customers are also impressed by the heat pump’s compact size, modern design and quiet operation. As a monobloc heat pump, the heart of the system – the refrigeration circuit – is located in the outdoor unit, simplifying installation and eliminating the need for an additional refrigeration technician.
The choice of three different indoor units – Basic, Style and Comfort – allows easy customisation to suit individual application. The simple installation and cutting-edge control units also impressed both trade visitors and end users.

Full-service provider of renewable heat

Just as exciting is the new Nano-PK 38-65 kW pellet boiler for the medium output range. This brings modern nano-pellet technology to commercial, residential and public heating systems. The compact Smart-Duo 17-30 kW combi boiler is also unique. It has a 2-zone combustion chamber for pellets and logs, enabling crisis-proof and cost-effective operation. An optional “eCleaner” can be integrated into both appliances, which reduces fine dust levels to a minimum. The boilers also impress with their modern design and extremely small footprint, making them ideal for installation in any boiler or utility room.

A small insight
Further innovations
For buildings with no space for a storage room, a maintenance-free garden shed offers a perfect solution for an outdoor pellet bag silo. Developed in collaboration with our partner Biohort, the HighLine garden shed has a modern design, and offers excellent value for money.
The new generation control features a capacitive touch display and modern remote controls. The integrated ‘Intelligent Weather Function’ optimises the control of your smart Hargassner heating system by using the three-day weather forecast for your location to automatically adjust the temperature. This saves both energy and heating costs!

In addition to new products, Hargassner also showcased proven systems such as pellet, wood log and combi boilers, wood chip systems, thermal solar panels and all related accessories.
Visitors to the trade fair were able to discover the MAGNO high-performance boiler, which has a capacity range of 300 kW to 2.5 MW, designed for commercial and industrial applilcations. It is also used in regional district heating plants to provide heat for public buildings and entire towns.
A wide range of pellet storage systems, wood chip extraction systems in different sizes and designs and a variety of refuelling systems are available. If there is no space for a heating or storage room in the building, Hargassner offers ready-made outdoor heating modules with one or more boilers.
