Energy-efficient circulation pump (Class A) – ensures even heat distribution with reduced energy use
Mixing valve options – thermostatic or constant temperature control for safe supply temps
Over-temperature protection – prevents overheating (approx. 55–60 °C max supply temperature)
Adjustable bypass valve – supports single-pipe systems and optimises flow/temperature balance
Compact, corrosion-resistant design – bronze and high-quality materials for long service life
Flexible control options – room thermostat, thermostatic head, or remote capillary sensor
Quick installation – modular setup with integrated components
The Lowara BM Mixing Modules are designed for efficient heating control in hydronic (surface) heating systems, making them suitable for both new installations and retrofit projects. They allow surface heating circuits to connect directly to radiator circuits, eliminating the need for a separate low-temperature loop. Ideal for floor heating retrofits or room installations up to 200 m², each module comes fully equipped with a circulation pump, thermostatic or constant temperature mixing valve, bypass, and built-in over-temperature protection.
Surface heating area:
BM Mini – up to ~40 m²
BM Eco / larger models – up to ~200 m²
Max system pressure: 10 bar (1 MPa)
Max radiator circuit temperature: up to 110 °C
Max surface heating supply temperature: ~55–60 °C
Differential pressure tolerance (radiator circuit): up to 1 bar (100 kPa)
Pump power consumption:
BM Mini – approx. 25 W
BM Eco – 9–35 W (depending on operating conditions)
Connection sizes:
Boiler circuit – ¾″
Surface heating manifold – 1″ (varies with model)
Materials: bronze valves, stainless steel pump parts, durable thermostatic component
Retrofitting floor heating into existing radiator-based systems
Individual room or apartment heating with independent temperature control
Compatible with high-temperature radiator boilers (up to 110 °C)
Energy saving through efficient circulation and precise control
Flexible installation – suitable for both visible and recessed setups
Safe and reliable – built-in protection against overheating
BM Mini KF
Thermostatic head with remote capillary sensor
Includes: bypass, over-temperature protection, bleed screw
BM Mini RT / KR
Electrical drive + thermostat or constant temp control
Optional cabinets and accessories
BM Eco ZR
Zone terminal block and pump shut-off module
Compatible with manifolds, flow meters, and shut-offs
Heating area: up to 200 m²
Boiler circuit temperature: up to 110 °C
Surface heating supply temperature: ~55–60 °C
Pressure rating: 10 bar
Pump power: 9–35 W (larger modules), ~25 W (smaller modules)
Connections: ¾″ (boiler side), 1″ (floor heating side)
Controls: thermostatic head, room thermostat, or constant temp controller with over-temperature protection
Yes, they are suitable for new builds and retrofitting existing radiator systems, allowing direct connection to surface heating circuits.
Each module includes a mixing valve with thermostatic or constant temperature control, ensuring the surface heating supply remains at safe, comfortable levels (~55–60 °C).
Depending on the model: BM Mini up to ~40 m², BM Eco/larger modules up to ~200 m².
