1 System overview and customer benefits
1.1 System overview
Space heater 48-65kW View without casing
Potential applications
The Space heater units are intended for use as heat generators for closed domestic hot water
central heating installations and for central domestic hot water generation in households.
The Space heater units are delivered only as circulation water heaters with unit outputs of 48 and
65 kW. The domestic hot water generation is used in combination with domestic hot water cylin-
ders (FT series; solar cylinder).
─For radiator and underfloor heating, as well as peak-load boilers (Space heater unit types).
─Space-saving installation in the central utility room for the modernisation and new construction
of non-residential buildings, such as offices, businesses, restaurants, ...
─Flexible installation for systems and applications, e.g. cascade applications, hybrid applica-
tions, etc.
─Open-flued or room-sealed operation with a system-certified flue gas system.
─ErP compliant with an efficiency of 94%, A+ (combined with class VI control; ERP)
Equipment
─High-efficiency pump, water pressure sensor
─Stainless steel integral condensation heat exchanger
─Integrated cylinder/domestic hot water control system with prioritising diverter valve
─Diagnostics system with illuminated plain text display
─eBUS, integration for "Connectivity" available as an option.

Example: Heating system without low loss header; 1 x non-regulated heating circuit; domestic hot
water supply; 1 x MiPro; 1 x MiLink
Area of application: Single-occupancy house
Remote access via "MiConnect"/MiPortal
New! For 7-coil and 9-coil heat exchangers (48 kW + 65 kW)
Additional software function for the direct supply of the heating circuits, possible
without low loss header.
The direct supply is made possible by a new software function and a new 3 way valve (Orkli 11/4").
