steel boiler

- 32 months

The boiler is constructed for burning pellets with a burner for pellets mounted  into the left or the right side of the boiler. The burner draws pellets from the storage tank by means of a screw conveyor.

The boiler can also burn dry wood after having dismounted the pellets burner.

The boiler is equipped with a gas exhaust ventilator, which withdraws the combustion gases from the boiler.

Advantages of the ATMOS D...P pellet boilers:

  • High comfort of heating
  • Ecological burning
  • Use of renewable source of energy
  • Automatic operation
  • Automatic ash removing – in case of installing with ash remover


ATMOS boilers must be connected to the LADDOMAT 21 or ESBE TV thermoregulation valve to achieve and keep the minimum temperature of water returning to the boiler at 65°C. The temperature of water exiting the boiler must be permanently kept between 80 – 90°C.

The default configuration of the boiler includes a cooling circuit to prevent overheating. You just need to buy the thermal release valve Watts STS 20.

We recommend installing these boilers with accumulation tanks.
