M-TEC launches first propane heat pump with up to 26 kW heating capacity, suitable for indoor installation and containing less than 150 g of refrigerant
A modular system kit for geothermal energy, groundwater, PVT and air
With the introduction of its propane heat pumps with a heating capacity of up to 26 kW for installation inside buildings, M-TEC is setting a new standard in heating technology. The heat pump can be configured in a modular fashion and, in all variants, remains below the safety-relevant 150 g refrigerant limit for propane.
The solution is based on an innovative stacking concept that connects several heat pump modules with each other, thereby reducing the amount of propane R290 refrigerant required. A total heating output of up to 26 kW can be achieved. Available for ground, water, PVT and air heat sources.
Simply connect and you're done: our individually configurable heat pump modules do not require any special ventilation concepts or gas detectors, as they always remain below the safety-relevant refrigerant limit specified in the applicable standards.
Configurable concept in modules
Whether for detached houses, multi-storey residential buildings or office buildings, whether for new builds or renovations: the modular concept allows flexible configuration for a wide range of requirements. Up to four heat pump units with an output of 6.5 kW each can be combined in a vertical modular system, which can be cascaded three times to achieve an output of up to 78 kW.
The central control system regulates the cooling circuits, heat sources and heating circuits, among other things. An 8.8 kW electric heating element for peak loads, redundancy and fast heating phases is already integrated. Depending on customer requirements, cooling can be active or passive (i.e. without heat pump operation). For high tap capacities, M-TEC offers an optional 200-litre hot water tank.
Integrated source management
M-TEC has developed and optimised the heat pump system for geothermal energy, groundwater, PVT modules and air. Active source management allows the combination of several heat sources such as deep boreholes, geothermal baskets, ice storage, air evaporators and PVT collectors. An integrated PVT mixer enables source temperatures of up to -25 °C and +80 °C.
Intelligent energy management
The new heat pump can be integrated into both M-TEC’s E-Smart energy management system and third-party systems. E-Smart provides a comprehensive energy solution that integrates photovoltaics, battery storage and charging stations. Control in accordance with Section 14a, variable electricity tariffs, self-consumption optimisation and much more can be installed with ease.
The modules can be combined as required.
- 6.5 kW heat pump module (HPM): Inverter-controlled unit (2–6.5 kW) with R290, speed-controlled brine and heating circulation pumps, expansion vessel (12 l), optionally with active cooling.
- Control and hydraulic module (OTM): AP440 heat pump control with IM105/IM110 expansion module, 8.8 kW electric heating element, safety thermostat, hot water changeover valve, upward or rear connection piping (light version) and optional PVT mixer.
- Passive cooling module (PCM): Heat exchanger with changeover valve for cooling without compressor operation.
- Boiler module (DHWM): 200 l hot water tank with integrated heat pump central control.
