A powerful double-circuit gas boiler with a closed combustion chamber from one of the largest manufacturers of heating equipment — Bosch Thermotechnology GmbH. It is the top model from the 2015 Logamax U072 line. It features an impressive useful thermal power (35 kW), moderate overall dimensions of the body, a practical microprocessor control system and high efficiency. It is positioned as a product of the middle price category, intended for organizing heating and hot water supply systems in private houses, apartments, office, commercial and household premises with a total area of up to 280 m2. Thanks to the use of a closed combustion chamber and a forced smoke exhaust system, it works with a relatively simple coaxial chimney system and can be installed directly in residential areas. The B...uderus Logamax U072-35K boiler is a highly integrated complete solution that includes an 8 liter expansion tank, a three speed low noise circulation pump, a modulating stainless steel burner, reliable gas automation and a full range of sensors for safe operation. This model is insensitive to moderate voltage drops in the electrical network and is able to maintain performance at reduced gas pressure.
