Logamax plus GBH172iT gas condensing hybrid system.

The Logamax plus GBH172iT combines gas condensing technology with solar heat or other renewable energies intelligently to make efficient use of the benefits of each energy source. This dramatically reduces the volume of CO2 emissions. And since this helps towards the fulfilment of the climate targets, the Logamax plus GBH172iT is also eligible for government subsidies.

Overview: Product.

At a glance:

  • All-rounder for system integration of renewable energies such as solar, stoves or air to water heat pumps
  • Buderus hybrid technology with a significant efficiency advantage in comparison with standard combi cylinder solutions
  • Integrated hybrid mixing valve to reduce sources of faults and the effort required for installation

Overview: Product.

Compact and efficient:

  • Minimal installation surface thanks to the combination of a wall mounted gas condensing boiler and DHW cylinder in one appliance
  • Efficiency class A+ and high modulation range of up to 1:8 (heating) and 1:10 (domestic hot water)
  • BEG-ready: Integrated energy consumption and efficiency display provides information and facilitates optimisation

Overview: Product.

Maximum convenience for domestic hot water whilst small in size.

  •  Integrated 100 l stratification cylinder and domestic hot water output of 30 kW
  • Surpasses the domestic hot water convenience of a wall mounted condensing boiler with adjacent 200 l DHW cylinder with indirect coil
  • Unlimited 38°C water temperature in a standard shower (14l/min)
  • Fill a bathtub (200 l) at a water temperature of 38°C in 10 minutes

Assembly: Hybrid technology.

Buderus hybrid technology for the highest level of system efficiency.

  • Integrated hybrid mixing valve for safe and quick assembly without sources of faults
  • A significant efficiency advantage in comparison with standard combi cylinder solutions
  • No storage of fossil energies in the buffer

The integrated hybrid mixing valve.

  • Internal 3-way mixer for priority usage of renewable heat from the buffer cylinder
  • Efficient use of existing heat sources
  • Quick and precise control of the required flow temperature (heating circuit and domestic hot water)
  • Integrated control function to protect against scalding

Assembly: Plug & Warm.

Plug & Warm – for significantly faster installation.

The buffer cylinder can be connected to the Logamax plus GBH172iT directly and without additional effort. No additional mixing valves or control elements, or – for a heating circuit – no low loss header or external heating circuit set are required. The result is: A highly compact design, significantly reduced effort required for installation and a considerable reduction in sources of faults.

Optimum accessibility during assembly.
Because it is possible to connect the horizontal connection set (CS10) and the shut-off valve connection set (CS28-1) before installing the wall mounted gas condensing boiler on the cylinder.

Assembly: Plug & Warm.

Good accessibility thanks to a modular design.

The connection set is installed via the integrated connecting plate. The piping is aligned at the top or at the side (left/right) depending on requirements. With the direct connection via the CS42 set, the connection can be made directly on the appliance provided by the customer.

Delivery in stages enables convenient transport and refitting. The two-piece casing facilitates accessibility for assembly and maintenance. It can also be removed for a flue system that is already installed.

Sophisticated construction.
The insulation on the plate heat exchanger for domestic hot water heating can alternatively be used as a collector trough for residual water during removal.

Overview: Transport and maintenance.

Makes your work easier:

  • Hassle-free transport: Supplied in two parts
  • Particularly maintenance-friendly: Two-part appliance cover for convenient maintenance
  • “Plug & Warm”: Convenient installation thanks to an intelligent assembly concept

System: System integration.

Modular design enables expansion.

This is system expertise how we like it at Buderus: The Logamax plus GBH172iT opens up various possibilities for efficient, renewable and future-proof system integration – from solar central heating backup to integration of pellet burners or stoves, or a heat pump.

System: System integration.

Basis: Solar central heating backup.

  • Four Logasol SKN4.0 or SKT1.0 solar collectors, Logasol KS0110 SM100/2 solar pump station
  • Ideal combination for an introduction to solar central heating backup
  • Solid Logalux PNS400/5 buffer cylinder
  • The best price-performance ratio

System: System integration.

Convenience: Solar central heating backup and/or stove integration.

  • Four or five Logasol SKN4.0 or SKT1.0 solar collectors, or eight Logasol SKR10 vacuum tube collectors, Logasol KS0110 SM100/2 solar pump station
  • Efficient and flexible Logalux PNR500/750 EW-C buffer cylinder with temperature-sensitive return flow supply
  • Stove integration for use of biomass, such as with the balanced flue Logastyle Lamina pellet stove

System: System integration.

Premium: Air to water heat pump and photovoltaics.

  • Easy integration of a heat pump that has been set up externally via a hybrid box incl. hybrid manager HM200
  • Optimum combination with photovoltaics thanks to thermal storage of self-generated current in the buffer cylinder
  • Increases self-sufficiency and domestic consumption rate
  • Logalux P200 heat pump buffer cylinder

The hybrid box.
This is the link between the buffer cylinder and the heat pump outdoor unit. Therefore, no additional indoor unit for the heat pump is required because the hybrid manager HM200 controls the interaction between the wall mounted gas condensing boiler and the heat pump. What's more, the pre-assembled box means that it is exceptionally easy to assemble and saves time during installation.

System: Subsidy.

Renewable ready.

“Renewable ready” is the prerequisite for subsidies for wall mounted gas condensing boilers. To do this, they must fulfil the following criteria:

  • Hybrid-compatible control technology
  • A detailed planning concept for future use of renewable energies in the heating system
  • Cylinders for the future integration of renewable energy
  • Hydraulic balancing

The Logamax plus GBH172iT gas condensing hybrid system meets these requirements exactly.

System: Subsidy.

Climate protection is worth it.

Renewable heating systems and efficient buildings are being promoted as part of the climate package. This includes heat pumps, pellet stoves and solar thermal systems. Benefit from state subsidies and let us advise you.

The new BEG.

The new BEG (German federal government subsidies for efficient buildings) is replacing the existing programmes from the Credit Institute for Reconstruction (KfW) and the Federal Office of Economics and Export Control (BAFA). Proven elements have been developed further and bundled into three sub programmes, which is intended to make the subsidy programme easier to understand for citizens, companies and municipalities.

Buderus is BEG-ready:
Buderus already complies with the recording quantities of heat and the energy consumption and efficiency display required as part of the BEG individual measures from 2023, enabling customers to monitor and optimise their consumption.
