The new residential heat pump system can be configured modularly and requires less than 150 grams of refrigerant, allowing it to be installed indoors. The system integrates with M-Tec’s energy management platform and supports multiple heat sources, photovoltaics and battery storage.
Austrian manufacturer M-Tec has presented a new propane heat pump for homes that offers a heating power of up to 26 kW and is suitable for indoor installation.
The new product is designed for single-family homes, multi-family homes and office buildings. Its flexible configuration makes it suitable for both new construction and renovation projects.
The company said the heat pump system is modularly configurable, with all versions staying below the safety-relevant refrigerant limit of 150 grams, allowing it to be installed indoors.
Up to four 6.5 kW units can be combined in a vertical modular system, which can be cascaded up to three times for a total output of 78 kW, the company explains. The system is centrally controlled and has an 8.8 kW electric heating element for peak load, redundancy and rapid heating.
On request, the system can also provide active or passive cooling. M-Tec offers an optional 200 liter hot water tank.
“Simply connect and you’re done: Our individually configurable heat pump modules do not require any special ventilation concepts or gas detectors, because they always remain below the safety-relevant refrigerant limits of the applicable standards,” says Peter Huemer, CTO of M-Tec.
A source management system is integrated, allowing the heat pump to operate with geothermal energy, groundwater, photovoltaic thermal (PVT) modules and air. Thanks to the active management system, multiple heat sources can be combined. The PVT mixer supports source temperatures from -25 C to 80 C.
The heat pump can also be integrated into M-Tec’s “E-Smart” energy management system or into third-party systems. This enables a complete solution including solar photovoltaics, battery storage and charging stations. Features such as control under Article 14a of the Austrian Energy Sector Act (EnWG), variable electricity tariffs and self-consumption optimization are also supported.
