ETA Combination Boiler eSH 16 to20 kW with eTWIN 16 kW
Flexible heating with
logs and pellets
ETA eTWIN: It stays warm even without refueling

You want to enjoy the advantages of a log boiler, but you also want it to stay warm even if you don't have time to refill it for a longer time?

Then the ETA eSH-TWIN combination boiler, consisting of an ETA eSH log boiler with an additional pellet burner, is the right solution.

It ignites automatically in both log and pellet mode - if no logs are inserted, pellets are fed fully automatically.

Convenient and flexible

No log boiler runs fully automatically, but the eSH comes close: normally, you only have to add logs once a day - and you don't even have to light it. The boiler lights itself when heat is needed. The eTWIN does the same and is even more convenient: if no logs are available and heat is requested, the pellet boiler starts fully automatically. The free choice between logs and pellets also allows you to react flexibly to future price developments.

The many advantages of wood
Heating with wood is not only better for the climate than oil & gas, but also for the wallet - and not only at the moment, but for many years, as the graph below confirms. Moreover, it is resistant to crisis, because wood is available in abundance in Europe. Soot emissions are always criticized, but these are massively reduced in the eSH log boiler and the eTWIN: The "e" stands for efÏciency and the option of installing an electrostatic precipitator, which uses electrical voltage to remove dust particles from the flue gas.
