Quick Overview

Ruben BO 21kw Contemporary Stove with 4 Port Back Boiler. "Eco Design 2022 Compliant"


A stylish wood burning and multi-fuel stove, that incorporates a large ceramic glass window, silver door handles / controls and an integrated back boiler for hot water and central heating. Hand built in Europe to a high standard and finished in charcoal dark grey (almost black), with a choice of Red or Ivory coloured sided, the Ruben BO is a substantially constructed stove, and is finished to the very highest of standards.


The integrated back boiler offers 7kw to water heating, leaving 8kw to room heating. There are 4 water connections on the rear of the stove, 2 x flow and 2 x return, all connected to one chamber - size = male 1" BSP. The 18.64 litre back boiler on this stove is extremely efficient and will heat up to 10/12 radiators and domestic hot water.


The back boiler is designed to be used on an un-vented hot water system up to a maximum operation pressure of 2 bar, (rated up to 4 bar) it can also be used on a non pressurised "vented" hot water system. 


In addition the back boiler incorporates an internal cooling coil, which runs through the main back boiler. The purpose of the coil is to cool the water within the back boiler before it reaches boiler point. This is achieved with an additional control valve called a TAS valve. The cooling coil is designed to be fed by a mains cold water feed, and the cooling water is then discharged to waste water drain. The mains cold water feed is controlled by a mechanical TAS valve which monitors the temperature of the water within the back boiler and opens when the water reaches 96 degrees. This releases a burst of mains-cold-water, which is released through the cooling coil, thus reducing the temperature of the water within the back boiler. The cooling water is kept separate from the water within the back boiler and therefore no contamination can take place. The mains cold water is then discharged to an outside drain. 


When using the Ruben BO 4 port stove with an un-vented hot water system,  we recommend that you install a 25 litre expansion vessel and at least two 3 bar pressure release valves. We also recommend that you use our approved "thermostatic pump station" in order to increase the efficiency of the stove. Please note that the TAS valve is not included with the stove.



Primary and secondary air controls allow complete and effective control over both the burn rate and temperature output, in order to maximise the efficiency of the stove. The iStove Lux also has an advanced pre-heat air wash system that ensures the large glass window stays clean to give a clear view of the flames. Further features include a large removable ash pan for easy cleaning and maintenance and a multi fuel fire grate.


The stylish design and clean lines compliment the contemporary look of this compact, yet high output stove.
