Boilers combine economy with compact design

The boiler options are equally appropriate for tall buildings, offering 8 bar maximum pressure; while being lightweight (290 to 595kg when empty), so the range is suitable for roof top applications where structural limitations may be a consideration. Inspection glass and ignition electrodes can be fitted in different locations to suit space limitations – and there is the option to specify a room-sealed version, with no change to the standard boiler.

Like their predecessors, the R600 models are designed for single or cascade applications: sharing load and optimising system flexibility, particularly for routine maintenance work.

It is not just practicality that Stokvis has applied to the design of its new boiler range:  all offer the performance benefits of the manufacturer’s water-cooled, down-firing, premix burner system. The fully modulating burner facilitates high turn down ratios to optimise efficiency at low system loads, while the robust stainless steel heat exchangers provide the boiler with a very long life

As a result the R600 range boilers deliver an eco-friendly class 6 NOx level, and are able to return seasonal efficiencies up to 110.4%.  The construction of the units even includes the sustainable aspect of fully recyclable component parts.

 Optional extra low loss headers are available, and if being used in a retrofit application onto existing systems, Stokvis Econoplate plate heat exchangers can be incorporated to create total boiler isolation from what might be a contaminated system. 

Control options include those to address dual heating zones; a master\slave cascade control for up to eight boilers; a room unit for each heating zone and a choice of sensors including outdoor temperature compensation, DHW, heating zone and a low loss header sensor for cascade applications.
