Combicesse atmos DC GSP (eligible)

ATMOS GSP combi boiler for wood and pellets

_____________________________________________________________________________________________

Note on funding!

The Atmos GSP series combi boilers are split in terms of funding. The 25 and 30 kW combi boilers are eligible without a particle separator. The 18 and 40 kW combi boilers only meet the requirements with a particle separator.

We only offer eligible options online.

If you would like the 18 kW or 40 kW combi boiler variant without a particle separator and without a pump, please let us know in advance and we will prepare an individual offer for you.

For those who want to heat with wood inexpensively but still enjoy the convenience of an automatic heating system, our GSP combi boilers are the perfect solution. A major advantage of the ATMOS GSP combi boiler over other products is that the combustion chambers are arranged one above the other, thus requiring minimal space. This space-saving feature has made GSP boilers highly sought after and they have become firmly established since their market launch in 2012.

The GSP series includes the boiler types DC18GSP, DC25GSP, DC30GSP, and DC40GSP, and most recently, DC25GSP-PA and DC30GSP-PA (with particle separator). All boilers are equipped with the A25GSP pellet burner and receive government subsidies due to their high efficiency of over 90% and low emissions.

For assembly:

The wood component of the DC18GSP is based on the DC18GSE, and the DC25GSP, DC25GSP-PA, and DC30GSP, DC30GSP-PA are based on the DC25GSE and DC30GSE wood gasifiers, respectively. Behind the upper door is the filling chamber of the wood gasifier. This chamber is very large (as is the case with the GSE wood gasifier). The DC18GSP holds 85 liters of wood, and the other two boilers have a filling volume of 125 dm³ and hold Logs up to 58 cm long. This makes wood heating more convenient, as a large amount can be added at once during the filling process.

Behind the middle door is the combustion chamber of the wood gasifier. This consists of ceramic combustion bowls, which give the boiler a long life and ensure excellent combustion values. If, after years of wear, the ceramic parts become worn and require replacement, each individual ceramic part can be replaced inexpensively and easily.

Behind the lower door is the pellet burner's combustion chamber. If desired by the system operator, this can be started automatically once the buffer tank has cooled down. In conjunction with our JBR Wi-Fi control system, this process can even be controlled remotely via phone, tablet, or PC.

Equipped with Dual Belimo

The ATMOS GSP combi boiler (like the GSPL and KC SPL combi boilers) features a Belimo actuator that performs two functions. First, it reduces the air supply in pellet mode when a defined flue gas temperature is reached. This ensures the boiler's high efficiency. The second function, the Belimo, closes the same air damper 100% when the boiler is in pellet mode. This eliminates falsified flue gas values, and the boiler can be adjusted and measured without any modifications.

Pellet burner A25 GSP

Unlike the standard A25 burner, the new ATMOS A25GSP pellet burner features a Belimo actuator that completely closes the air duct when the GSP boiler is in wood-fired mode. This prevents air circulation through the pellet burner, allowing the boiler to be measured and adjusted immediately in wood-fired mode. Automatic switching to pellet mode after the wood has burned out is therefore fully possible.
