ETA SH
20–60 kW Wood Gasification Boiler
The ETA SH boiler is one of the most efficient log systems available, with minimal user input needed. Any kind of wood can be burnt using ETA’s reverse combustion technology, with efficiency of up to 94%. The boiler automatically re-ignites itself through ember preservation for up to 24 hours and in winter it needs refuelling as little as once a day, less in summer. A highly efficient and simple log boiler. At full output it uses 87w of electricity or less.
Key Benefits
- Large fuel chamber – The large chamber can take a high volume of logs so you may only need to refuel it once a day.
- Re-Light Without Matches – Embers are preserved for up to 24 hours so it will automatically ignite additional wood.
- Oxygen Sensor (Lambda Control) – The special oxygen sensor continuously monitors exhaust oxygen and automatically adjusts air induction to ensure optimal efficiency burning any kind of wood while minimising carbon monoxide (CO) emissions.
- Simple ash removal and cleaning – Ash is easily removed from a single front door and the heat exchanger can be cleaned simply by pulling a cleaning lever.
- Complete Regulation – The easy-to-use display on the front door gives you real-time monitoring and adjusting of the accumulator tank, hot water tank and heating pumps.
- Reverse Combustion Technology – This burns the gas contained in the wood as well as the wood fuel, increasing the efficiency and making use of every bit of energy.
- One of the best Boilers in its Class - Approved by the BLT Weiselburg (Austria) and the TUEV South Germany the ETA SH qualified itself as one of the best boilers in its class with the lowest pollutant values and highest efficiency levels.
