TIS PRO is a modern boiler that does not require connection to electricity and is characterized by a long burning time with a single fuel load.
The boiler is designed for burning non-wood biomass in the form of straw briquettes and is equipped with a mechanical air draft regulator that allows maintaining the desired temperature.
These boilers are primarily intended for export.


Thanks to its unique structural design, the boiler fully recovers the thermal energy generated from the burned fuel.
A special secondary air supply system ensures complete combustion of flue gases, with temperatures reaching a maximum of 130°C, resulting in very high efficiency and up to 12 hours of operation on a single fuel load.
The boiler features wide-opening doors and a cast-iron grate for convenient operation.
One of its main advantages is the large combustion chamber (larger than comparable competitor models), which contributes to the long operating time of the unit. This model can also be connected to a domestic hot water tank (DHW).
The boiler’s design allows for the installation of a controller and fan.
It is made from high-quality steel — the water jacket and heat exchanger are constructed from special boiler-grade steel (P265H) up to 6 mm thick.
Operation and cleaning of both the boiler and the heat exchanger are performed from the front side.
The housing has a modern powder-coated finish combined with 50 mm of insulation, ensuring reliable and long-lasting operation throughout the boiler’s lifetime.
TIS PRO is equipped with a boiler draft regulator.
When properly used and maintained, the boiler is designed to operate for at least 20 years.
Warranty:
5 years for boiler body tightness
2 years for all other components
