Heat exchanger with ALU plus technology.
High‑quality Buderus wall mounted condensing boilers work with cast aluminium heat exchangers with an efficiency of up to 98 %* and a very low power consumption in standby mode (2 watts). The ALU plus surface finish reduces dirt deposits and combustion residue – for lower maintenance costs and a long service life.


Products: Logamax plus GB192i
Optimally equipped:
The new Logamax plus GB192i
When optimum efficiency and outstanding comfort are top priorities, look no further than the innovative Premium type series, featuring high‑quality black or white titanium designs. The Buderus ALU plus heat exchanger and expanded modulation up to 1:10 lay the foundations for a system energy efficiency rating of A+.
The Logamax plus GB192i can easily be expanded with a heat pump, solar heat or biomass to form a future‑ready hybrid system.

Service: Subsidy.
The BEG subsidy programme.
The 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.
