The Sonniger HEATER R fan unit heater (LPHW) is ultra lightweight for its type and ideal for all commercial and industrial applications: retail outlets; leisure centres; exhibition halls; warehouses; factories; garages; workshops; plant rooms.
Ideal for use with hot water generated from biomass boilers as well as gas and oil fired boilers. The R2 and R3 models can be used with ground source heating schemes also.
The ambient-air model operates as a de-stratification device mounted horizontally.
Note: heating outputs in the model selector (kW) are based on a mean water temp 70C & internal ambient temp 20C

The Sonniger Heater R unit heater (LPHW) is a groundbreaking solution for heating commercial and industrial buildings. It is uniquely designed and manufactured from expanded polypropylene which reduces the weight of a typical 70kW unit by up to 5 times that of a traditional steel encased unit heater. This results in ease of installation for the contractor, a lifetime casing guarantee for the customer and significant benefits to the environment.
