Benefits

Very high efficiency values for low running costs

Combined with a flue gas or condensing heat exchanger, the UT-H uses the energy supplied even more efficiently. Potential fuel savings of up to 15%. Additional efficiency components such as combustion optimisation and the high-quality Bosch insulation concept can further increase the efficiency of your boiler system.

Versatile operation for the manufacturing industry and district heating grids

The UT-H produces energy-efficient process heat as a single- or multi-boiler system in a high temperature range up to 225 °C at up to 30 bar. The Bosch boiler is particularly well suited to process heating systems in industrial and commercial applications, and to support heating plants.

Customer-specific design and future-proof technology

Bosch builds the UT-H according to project-specific requirements and with individual equipment. The boiler and burner technology are perfectly aligned for environmentally friendly heat production. The technology can be retrofitted to run on climate-neutral fuels such as biogas, bio-oil or green hydrogen at any time.

User-specific control which offers integration of other control systems and remote monitoring

The UT-H can be easily controlled using the Bosch CWC compact control or BCO boiler control. The pre-configured protocols enable seamless connection to your automation system. The optional MEC Remote access allows you to quickly spot any operational changes.

Custom designs for heat recovery boilers

Bosch offers custom UT-H versions for project-specific requirements, as a heat recovery boiler with firing and fourth pass for the proportional use of waste heat or as a pure heat recovery boiler. Existing waste heat sources, such as from CHP or gas turbines, can be used efficiently and sustainably – saving fuel and reducing emissions.

Proven and reliable construction Made in Germany

The applied construction principle used to produce the UT-H offers advantages in terms of service life and operating safety. The arrangement of the flame tube and reversing chamber ensures consistent heating even in cold conditions and reduces stresses in the boiler. The optimised water content enables the UT-H to quickly reach its operating temperature.
