Details of ETA SH Boilers
1.LARGE FUEL FILLING SPACE: fuel capacity of 150 litres in the SH 20/30 models and 225 litres in the SH 40/50/60 models means that refueling intervals kept to a maximum. 2. ZONE ISOLATED AND ANNEALED COMBUSTION CHAMBER: The combustion chamber is lined with a high temperature ceramic Fire Brick that is light and prevents ash build up. 3. LAMBDA SENSOR: The SH boiler uses a lambda probe to adapt the firing process to suit differing types of wood, it identifies the energy density of the timber through the oxygen content of exhaust fumes and then adjusts the burning process to suit. 4. EASY REGULATION: The control panel allows for easy, and accurate, regulation of the boiler, buffers, water cylinders and circulating pumps. 5. RE-LIGHT WITHOUT MATCHES: When you refill the chamber with new fuel you don’t have to go messing about with

6. GASIFICATION: Secondary burning of carbonised gas from the wood fuel (normally lost to the atmosphere in the exhaust gas) reduces emissions and ensures optimal usage of all wood fuel burned in the combustion chamber.Temperatures in the combustion chamber can reach up to 1200 °C as a result. 7. PRIMARY AND SECONDARY AIR ACTUATORS: The primary and secondary air valves have a regulated position feedback link to the main control panel; this allows accurate and subtle control of primary and secondary combustion whenever required. 8. SILENT COMPRESSOR: The boiler has a barely audible, step-less, regulated induction fan with speed feedback to the control panel. Max electrical power consumption of the motor is 76W. 9. EXHAUST GASES: Seamless replacement of previous boilers due to monitored exhaust gas temperature, feedback loop to control panel. 10. EASE OF REGULAR MAINTENANCE: Regular maintenance is easily done through the main front door, there is no need for extra side doors and hard to reach hatches. 11. EASY CLEANING: the heat exchanger is the easiest of tasks, just pull the shaker handle on the outside |
