Is your neighbour registered by SEI to install Atmos boilers? If he is not then he cannot commission the boiler for the SEI grant. The grant setup for the gasification boiler is very different than for pellet boilers. For pellet boilers once you are on the list you can commission any pellet boiler, for gasification boilers only people trained by the importer or the manufacturer can commission that boiler. If you are registered for an ETA wood gasification boiler but not an atmos then you cannot commission the atmos

I disagree with this quote very much, I have been working with gasification boilers for nearly 5 years and there is a huge difference between the cheaper boilers and the more expensive systems.
I have worked with Atmos Boilers, Attack Boilers (almost a carbon copy of the Atmos) plus the ETA Heiztechnik SH Log Gasification boiler and there is no comparison between them. People have different reasons for buying a cheaper boiler or a more expensive one and that's ok but to say that there is no difference is not correct.
From my experience here are some examples of the differences
- A draught fan that runs at a continuous level with now temperature or O2 control.
- Variable speed draught fan that is controlled in relation to the temperature of the exhaust gas and the level of O2 in the exhaust. O2 level is an indication of the moisture content in the burning fuel and the quality of the fuel (hardwood or softwood). O2 monitoring allows the boiler to alter burning settings so as to always have optimum burning conditions.
- Primary air flap that is lifted open/close by a chain connect to a thermostatic valve in the boilers water. no secondary air control
- Automatic primary and secondary air valve control that is controlled in conjunction with the exhaust fan speed. The O2 meter dictates that opening of these valves, for example wood up to 40% moisture requires more oxygen to burn than wood with moisture as low as 20%.
- depending on the type of wood, and other factors the efficiency varies from 80% to 83% heat converted into useable hot water.
- A much higher range between 92% and 94% converted into useable hot water.
- Two doors means that to light the boiler you have to reach into the boiler to ignite your kindling. Once the kindling is burning you then have to fill up the boiler with logs.
- Three doors. You can fill the boiler completely in one go and then open the middle lighting door for ignition without having to worry about burning your fringe. Also, due to the O2 stat the ETA is able to determine when the boiler is running out of wood fuel and starts to run an ember preservation program that will keep hot embers (when burning hardwood) in the chamber so that ignition the following day is automatic. If you are burning softwood these embers turn to charcoal at a much faster rate, but lighting then is as simple as rolling up a newspaper sheet and lighting the charcoal.
- no weather influenced heating
- weather influenced heating with built in zone timers
- 5 years parts on heat exchanger, 12 months parts on everything else
- 5 years parts and labour on everything
I could go on but I think that you can get the message from that
