Construction The REFO boiler is made of 6mm certified boiler steel and tubing. The circular shape of the boiler is a clear advantage, since this construction eliminates residual welding stress. The working temperature is always in excess of 61ºC, owing to the use of a by-pass thermostat and a pump in the return line. This arrangement prevents corrosion. For the combustion chamber and the gas combustion tube only replaceable stainless steel and ceramic elements have been used. This ensures perfect combustion without radiant heat losses when the gas is being burned. In every respect these are boilers with a long working life. Control panel The REFO microprocessor control panel has a very user friendly design. The user interface consists of a control thermostat, an overheat thermostat, a knob for fuel type / fuel quantity, a main switch and a button for forced auger operation. There is also a digital display showing the smoke temperature. The control system automatically adjusts to the varying heat requirements throughout the year, so that the output of the REFO boiler varies between 10% and 100%. However the lower limit depends on the condensation level in the smoke stack. All the electric wiring is carried out in the factory; for the connection to the mains an earthed 230 V plug is to be used. Safety The auger feed from the bin to the boiler has a pitch which helps to prevent the fire from moving backwards. During operation the blower produces an overpressure in the bin for the same reason. The auger tube is further provided with a thermostat controlled sprinkler, with a water container mounted inside the boiler cabinet. Maintenance The REFO boiler has vertical boiler tubes with the draught going downwards in the tubes. This is a great advantage since dust and ashes from the combustion fall downwards in the smoke chamber (no need to clean the boiler very often). For cleaning, the boiler door is opened and the ash bin with fly ash and dust can be pulled out and emptied.
